Interior paints Types– Distemper

Distemper is the oldest type of interior paint. It was traditionally made by mixing water, chalk, and pigments with animal glue or resins as binders. Earlier, it was the most commonly used paint for interior walls, especially in the early 1980s. Over time, distemper has evolved and is now available in different types and improved grades to meet modern interior requirements. People often confuse distemper with whitewash, but distemper delivers far better finish, durability, and performance. Unlike whitewash, which uses a simple lime-based coating, distemper offers better coverage and a longer service life.

Workers apply distemper directly over plastered surfaces without using primer or putty. They must remove it before repainting with modern finishes. It does not serve as a suitable base coat for superior paints.

There are two types of Interior Distemper paints

  • Dry distemper ( water based paint)
  • Oil bound distemper (OBD)

Dry Distemper

Dry distemper is a water-based interior wall paint made from chalk, lime, glue, and water. Painters apply it using a brush, and it provides a better appearance than traditional whitewash. Manufacturers supply dry distemper in powder form, which users mix with water and glue before application. To achieve an even and smooth finish, painters apply a minimum of three coats. This type of distemper creates a rustic or earthy look, making it suitable for ceilings and low-traffic interior areas. However, dry distemper is non-washable and has limited durability. Due to its low cost and simple application, homeowners consider it the most economical interior paint for residential use.

Oil Bound Distemper (OBD)

Oil-bound distemper (OBD) is an improved form of distemper that contains drying oils or varnish, which provide better water resistance. It is available in ready-mix form and can be applied using a brush or roller. When applied in at least three coats, it delivers a smooth matte finish. One of the key advantages of oil-bound distemper is that it is washable, making it more suitable for interior walls. The presence of drying oils improves coverage area and allows the surface to dry within four hours. OBD is affordable, durable, and available in a wide range of colours. It is commonly used on plastered surfaces, brick walls, and ceilings in residential and industrial interiors. Compared to dry distemper, oil-bound distemper offers better durability and performance.

Distemper forms available in market

Distemper availability in the market includes several improved formulations designed for better performance and finish. Today, distemper paint is commonly available in the following three main forms:

  1. Acrylic distemper
  2. Synthetic distemper
  3. UNO acrylic distemper

Acrylic Distemper

Manufacturers formulate acrylic distemper as a water-based paint using acrylic copolymers, making it an eco-friendly choice for interior walls. It delivers a smooth matte finish and offers better durability than traditional distemper. Painters find it easy to apply, low in odour, and well suited for residential interiors that require affordability with improved performance.

Synthetic Distemper

Synthetic distemper is a water-based, oil-bound interior wall paint designed to offer improved strength and durability. Available in a wide range of ready-made shades, it delivers a consistent and attractive finish. Over time, the oil-bound film hardens, resulting in better washability and longer-lasting performance compared to conventional distemper paints.

UNO Acrylic Distemper

UNO Acrylic Distemper is a cost-effective, water-based acrylic distemper developed for interior wall applications. It offers good washability and durability while maintaining a smooth matte finish. Available in over 950 shades, it provides long-lasting color retention and is ideal for budget-friendly residential painting projects.

Best interior wall paint finishes – Emulsion paints

Emulsion paints use a water-based formulation, produce very low odour, and remain the most preferred choice for interior wall finishes.They provide a smooth appearance, excellent durability, and easy maintenance, making them suitable for residential and commercial interiors.

The main ingredients of emulsion paint include pigments, acrylic or vinyl resins, water as the solvent, and performance-enhancing additives. The acrylic resin is present in an emulsion form and acts as a binder, helping the paint adhere to the wall surface while holding all ingredients together after drying. Pigments provide colour, opacity, and protection against ultraviolet (UV) light.

Emulsion paints are quick-drying, washable, and long-lasting. Most stains can be cleaned using mild detergents without damaging the finish. They emit very low VOCs, making them eco-friendly and safe for indoor use. Unlike oil-based paints, emulsion paints produce minimal odour. For best results, primer and wall putty coats are required before applying the final emulsion paintwalls and minimises the odours which are a part of other oil-based paints. Emulsion paints requires a primer coat and putty coats before applying finish paint.

Types of Emulsion Interior Paints

Emulsion paints are commonly called plastic paints, plastic emulsions, or acrylic emulsions. Technically, all interior emulsion paints use a water-based formulation, while plastic emulsion represents a refined type with a higher acrylic binder content. Therefore, while all plastic emulsions are emulsion paints, not all emulsion paints qualify as plastic emulsions.

Plastic emulsion paint is a water-based acrylic wall paint that provides a smooth and uniform finish. Compared to ordinary emulsion paint, plastic emulsion offers better washability, higher durability, and improved stain resistance due to the presence of acrylic resins. These properties make plastic emulsions the most preferred choice for modern interior walls.

Types of Plastic paints are as follows

  • Matte finish plastic emulsion
  • Eggshell finish plastic emulsion
  • Satin finish plastic emulsion
  • Semi-gloss plastic emulsion
  • Gloss plastic emulsion

Matte finish plastic emulsion
Provides a smooth, non-reflective finish that hides surface imperfections well. Ideal for ceilings and low-traffic interior walls requiring a soft, elegant appearance.

Eggshell finish plastic emulsion
Offers a slight sheen with better washability than matte. It suits living rooms and bedrooms where designers need a balanced combination of visual appeal and durability.

Satin finish plastic emulsion
Delivers a silky, pearl-like sheen with good stain resistance. Commonly used in high-traffic areas like hallways for easy maintenance and enhanced durability.

Semi-gloss plastic emulsion
Has noticeable shine and excellent washability. Ideal for kitchens, bathrooms, and areas exposed to moisture or frequent cleaning.

Gloss plastic emulsion
Provides a highly reflective, shiny finish with maximum durability. Best for doors, trims, and feature walls where strong visual impact is desired.

Understanding Thermal Bridging: Causes and Solutions

Leave a comment

Thermal Bridging in Buildings occurs when heat transfers through parts of a structure. This happens where insulation is reduced or interrupted. In construction practice, thermal bridges often happen at junctions, edges, and penetrations. High thermal conductivity materials allow heat to escape in these areas. Understanding the types of thermal bridging helps designers identify repeating, geometric, and point bridges within building envelopes. The causes of thermal bridging often include poor design detailing, structural elements passing through insulation, and improper installation practices. Over time, the effects of thermal bridging lead to heat loss, higher energy consumption, surface condensation, and mould growth. Additionally, thermal bridging insulation issues reduce overall thermal performance and occupant comfort. Addressing these aspects early improves energy efficiency, durability, and sustainability in modern building design.

Thermal bridging can have a major impact on a dwelling’s overall thermal efficiency, even in very well-insulated homes. According to recent studies, thermal bridging has been found to be responsible for up to 30% of a home’s heat loss.

In this blog, I will show you what exactly is thermal bridging, its consequences, causes, types and strategies to reduce them. Let’s get started.

What is a thermal bridges in Buildings and Construction ?

A thermal bridge is a part of an object that has a higher thermal conductivity than the surrounding areas. This allows heat to flow through it with the least amount of resistance. The object’s thermal resistance is reduced as a result of thermal bridges. It is also known as a cold bridge, heat bridge, or thermal bypass.

Thermal Bridging occurs when heat flows away easily through a part of the construction. This part has much less thermal resistance compared to its surroundings. This leads to uneven heating in a building.

Thermal bridges in buildings and construction are areas within a structure where heat flows more easily. This happens due to breaks or weaknesses in insulation. These bridges usually occur at junctions between walls, floors, roofs, balconies, and around openings such as windows and doors. When materials with high thermal conductivity pass through insulated layers, they create paths for heat loss during winter. They also lead to heat gain in summer. As a result, thermal bridges reduce energy efficiency. They increase heating and cooling demand. They may also cause surface condensation and mould growth. Identifying and minimizing thermal bridges in buildings and construction is essential for improving thermal performance, occupant comfort, and long-term building durability.

Effects of Thermal Bridging

Effects of thermal bridging significantly influence the energy performance and durability of buildings. Thermal bridging occurs when heat transfers through areas with reduced insulation, creating unwanted heat loss or heat gain. In buildings and construction, these weak points lower thermal efficiency and negatively affect indoor comfort. Understanding the effects of thermal bridging helps engineers and designers improve insulation detailing, reduce energy consumption, and enhance building performance.

  • Thermal bridging in buildings will increase the amount of energy needed to heat and cool a room. 
  • Results in condensation of moisture inside the building envelope
  • Cause thermal discomfort. 
  • Causes additional heat losses in colder climates and require more energy to mitigation
  • Increased heat loss in winter and heat gain in summer
  • Higher energy consumption and utility costs
  • Reduced overall thermal performance of the building envelope
  • Formation of cold spots on internal surfaces
  • Risk of surface condensation
  • Growth of mould and mildew
  • Discomfort for occupants due to temperature variations
  • Degradation of building materials over time
  • Reduced lifespan of insulation systems
  • Failure to meet energy efficiency standards and regulations

Thermal Bridging Causes

Thermal bridging causes arise mainly from design and construction gaps where insulation is interrupted. This interruption allows heat to pass through structural elements and junctions. As a result, energy efficiency in buildings is reduced.

  • The points where the wall and the floor come together
  • Wall-to-roof junctions
  • Pipe and cable access holes in the building envelope
  • Window and door reveals
  •  Steel wall links in masonry work, (e.g. cavity walls)

Types of Thermal Bridging

Types of thermal bridging describe the different ways heat flows through building elements where insulation is reduced or interrupted. Identifying these types helps designers control heat loss, improve energy efficiency, and prevent moisture-related problems in buildings and construction.

There are several types of thermal bridges, which can be further classified as follows:

  • Geometric thermal bridging
  • Material thermal bridging
  • Structural thermal bridging
  • Repeating thermal bridging
  • Point thermal bridging

Geometrical Thermal Bridges 

Geometrical thermal bridges are induced by the building’s geometry, as the name implies. They are more likely to occur with complex building forms. So it’s best to keep the overall design as simple as possible to avoid them. The examples include:

  • Corners of exterior walls
  •  Wall-to-floor junctions 
  • Wall-to-roof junctions 
  • Junctions between adjacent walls

Material Thermal Bridging

Material thermal bridging occurs when building materials with high thermal conductivity pass through or replace insulation layers. Materials such as steel, concrete, and aluminum allow heat to transfer more easily than insulating materials. As a result, heat escapes in winter and enters the building during summer, reducing energy efficiency. Material thermal bridging commonly occurs in wall studs, beams, columns, and fasteners. Identifying and minimizing material thermal bridging is essential to improve insulation performance, reduce energy loss, and enhance indoor comfort in buildings and construction.

Structural Thermal Bridging

Structural thermal bridging occurs when structural elements penetrate the building envelope and interrupt continuous insulation. Elements such as balconies, floor slabs, columns, and cantilevered beams create direct heat flow paths. These structural connections significantly increase heat loss and may cause surface condensation and thermal discomfort. Structural thermal bridging is common in reinforced concrete and steel structures. Proper detailing, thermal breaks, and improved design strategies help reduce structural thermal bridging and improve overall thermal performance in buildings.

Repeating Thermal Bridges 

Repeating thermal bridges follow a trend. And it is “repeated” over a large area of the building’s thermal envelope. The examples include:

  • Steel wall ties used in masonry cavity wall construction
  • Ceiling joists used in cold pitched roofs when insulating at the ceiling level
  • Split created by timber framing when insulation occurs between the studs

Thermal imaging of a building highlighting areas of heat loss, illustrating the effects of thermal bridging.

Repeating thermal bridges are normal and predictable. But still, they result in significant heat loss. Because of that, we should consider thermal bridging when calculating the U-value and during planning, design, and construction.

Point thermal bridging

Point thermal bridging occurs at localized points where small but highly conductive elements penetrate the insulation layer. Common examples include metal fasteners, anchors, screws, and fixing brackets used in building construction. Although each point bridge is small, their combined effect can lead to noticeable heat loss and reduced thermal performance. Point thermal bridging may also cause cold spots on interior surfaces, increasing the risk of condensation. Minimizing point thermal bridging through proper detailing and low-conductivity fixings improves energy efficiency and overall building performance.

Non Repeating Thermal Bridges 

  • Thermal bridges appear periodically. And, they are located where the building’s thermal insulation has a split in it.
  •  Non-repeating thermal bridges can form where materials with different thermal conductivity come together to form the envelope. 
  • Examples include reveals around windows and doors, loft hatches, and other openings in the building’s thermal envelope.

Why should we avoid thermal bridging?

Let me give you a set of reasons that would prompt you to avoid thermal bridges during construction of a building.

Decreased Insulation Effectiveness

  • Buildings that are airtight and have high levels of insulation may be more vulnerable to thermal bridges. 
  • When high levels of air tightness and insulation are present, thermal bridges can account for up to 30% of heat loss. 
  • During the warmer months of the year, thermal bridges can actually cause an increase in heat gain. This can contribute to overheating of the indoor room.

Increased expenditure of energy

The amount of heat lost depends on the intensity and frequency of thermal bridges. it’s best to design and construct buildings with no thermal bridges. If you don’t, you’ll end up spending more money to maintain a constant and comfortable indoor air temperature. This will undermine the intention of installing energy efficiency measures in the first place.

Greater risks of Condensation, mould, and rot 

  • Thermal bridges can cause interstitial condensation within walls and other building elements.
  •  Since it cannot be seen from the inside or outside of the house, interstitial condensation can be extremely hazardous. 
  • As the interior temperature falls below the dew point, moisture in the warm air condenses into water droplets.
  • Mold growth is one of the most common side effects of condensation. 
  • Invisible mold can develop out of reach, resulting in poor indoor air quality and negative health effects for building occupants.

Strategies to reduce Thermal Bridging

Depending on the source, site, and form of construction, there are many methods that have been proven to minimise or eliminate thermal bridging. The aim of these approaches is:

  1. Either create a thermal break where a building component would otherwise stretch from outside to inside.
  2. Or, minimise the amount of building components that span from outside to inside.

 These are some of the strategies:

  • Using a continuous thermal insulation layer, such as rigid foam board insulation in the thermal envelope.
  • Lapping of insulation where direct continuity is not feasible.
  • Usage of Wall assemblies with double and staggered walls.
  • Using Insulating Concrete Forms (ICFs) and Structural Insulated Panels (SIPs).
  • Reduce the framing factor by removing unnecessary framing members.
  • Increased insulation depth by using raised heel trusses at wall-to-roof junctions.
  • Installation of high-quality insulation with no voids or compressed insulation.
  • Adding a gas filler and a low-emissivity coating to double or triple-pane windows.
  • Installing windows with thermally broken low conductivity frames.

Keep this strategies in mind so that they can help you construct a building with zero thermal bridges. Hope you found them useful. Let’s know in the comments.

Key Takeaways

  • Thermal bridging in buildings occurs where insulation is reduced or interrupted, allowing heat to flow easily.
  • It can account for up to 30% of total heat loss, even in well-insulated structures.
  • Thermal bridges commonly form at junctions, edges, penetrations, and structural connections.
  • Major effects of thermal bridging include increased energy consumption, condensation, mould growth, and occupant discomfort.
  • Thermal bridging causes often relate to poor design detailing, material choices, and construction practices.
  • The main types of thermal bridging include geometric, material, structural, repeating, and point thermal bridges.
  • Repeating and point thermal bridges may appear minor individually but cause significant cumulative heat loss.
  • Proper identification during design is critical.
  • Continuous insulation and thermal breaks reduce risks.
  • Accurate detailing improves energy efficiency and building durability.

Conclusion

Thermal bridging is a critical factor that directly affects the energy efficiency, comfort, and durability of buildings. Thermal bridges in buildings and construction allow uncontrolled heat flow due to insulation gaps, material conductivity, and poor detailing. Understanding the types of thermal bridging, along with the causes of thermal bridging, enables designers and engineers to address weak points in the building envelope. The effects of thermal bridging, such as heat loss, condensation, mould growth, and increased energy costs, highlight the importance of proper planning and execution. By adopting effective strategies like continuous insulation, thermal breaks, and improved construction detailing, thermal bridging insulation issues can be significantly reduced. Addressing thermal bridging early ensures sustainable, energy-efficient, and comfortable buildings that meet modern performance standards.

      Thermal insulation

      ALC panel got a unique cellular structure that constitutes around 75% to 80% air bubbles. These air bubbles are responsible for their low thermal conductivity. The ALC panels got a k value nine (9) times less than concrete and twice less than bricks. ALC panels got the highest thermal rating of R30 in the industry.
      The low thermal conductivity helps ALC panels in maintaining and retaining indoor temperatures. The indoors will be kept cool during summers and warm in winters. ALC panels can reduce substantial energy loads and thereby generates an energy bill savings of around 25%.

      High fire resistance

      ALC panels got a unique cellular structure. They provide a superior fire rating of around 4hr for a 100 mm thick panel. The melting point of ALC panels is over 1600 degrees Celsius. It is much higher than the typical building temperature of 650 degrees Celsius. ALC panels do not release smoke or toxic gas during a fire incident.

      Acoustic insulation- ALC panel

      ALC panels possess natural sound insulation properties. They can also reduce mechanical vibrations to an extend. Noise insulation of these panels ranges between 40-60Db depending on the thickness of the panels and surface treatments. They can function as sound absorption and a sound resistance material simultaneously, which is not possible with other building materials. A good STC rating of around 44 is ideal. This enables ALC panels to be used in areas designed to have high acoustic performance. Ideal for hotels, hospitals, commercials, and residential uses.

      Heat Strengthened glass

      Heat strengthened glass follows heating of annealed glass to a temperature of around 650-700 degree. The cooling process is much slower than the process used in the manufacturing process of tempered/toughened glass.

      Heat-strengthened glass is a semi-tempered glass. It retains the normal properties of ordinary float glass. Heat strengthening adds strength to the glass by inducing surface compression and limiting the breakage chances. For heat strengthened glass the compression induced is in the range of 6000 to 9000 psi. However compression induced is around 11000 to 20000 psi in the case of fully tempered/toughened glasses.

      • Heat strengthened glass provides necessary resistance to heat build up during external applications.
      • Heat-strengthened glass differs from tempered glass in surface compression and possess mechanical strength of about 1.6-2 times that of annealed glass.
      • These glass got excellent thermal stability, whereas its flatness and light transmission is equal to that of annealed glass and much better than that of tempered glass.
      • Three times more resistant to thermal stress in comparison to normal annealed glass.
      • It can withstand temperature difference of 100°C (in range of 50°C to 150°C) when compared to ordinary annealed glass which can withstand up to 40°C.
      • Heat strengthened glass is less susceptible to spontaneous breakage.

      Toughened glass

      Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to shatter into small granular chunks instead of splintering into jagged shards as ordinary annealed glass does. The granular chunks are less likely to cause injury.
