Kingspan Thermawall TW55 is an insulation material specifically designed for wall applications within residential and commercial buildings. Thermawall TW55 is manufactured with Nilflam technology. TW55 is made up of a high-quality fibre-free rigid thermoset polyisocyanurate (PIR) core. Both sides of the core have facings that are bonded to low emissivity composite foil during the manufacturing process. The foil facings improve the thermal resistance of any unventilated cavity adjacent to the board. This product is manufactured with a blowing agent with zero Ozone Depletion Potential and Low Global Warming Potential.
Key Features:
- Insulation for Steel Framing and Timber Systems
- Thermal conductivity as low as 0.022 W/m.K
- Convenient for use with steel and timber frame wall constructions
- Does not get affected through air movement
- Easy to install and handle
- Perfect for refurbishment
- Non–deleterious material
This board can be cut using a fine-toothed saw, this is accomplished by measuring the boards to size and making markings if necessary. Then placing the boards on a surface that allows the saw to go all the way through the board. A knife can also be used to score the board, then snapping the board over a straight edge, and then cutting the facing on the other side. Any of cut of the insulation board should be kept in case of gaps within the installed insulation.
Protective clothing is recommended to prevent particles that are produced from cutting insulation boards, from being inhaled or irritating to the skin and eyes. Goggles, face masks, and gloves can also be worn to provide protection.
Providing your home with the correct insulation materials will provide a more energy-efficient and sustainable environment by helping towards the prevention of global warming and climate change. Kingspan is a commitment to providing sustainable insulation and has made a commitment to help our planet. All Kingspan packaging is 100% recyclable.
The Kingspan packaging should not be considered as protection for the board against weather condition. The insulation board should be stored on a flat surface in weatherproof conditions preferable inside a building. If the boards should have to be stored outside the correct weatherproofing materials should be provided. Boards that have been allowed to get wet should NOT be used.
Kingspan Kooltherm TW55 can be installed in a range of methods. These methods include:

Frequently Asked Questions
Is TW55 vapour resistant?
Kingspan Thermawall TW55 ensures there is a layer of high vapour resistance on the warm side of the insulation layer. This will avoid condensation. If required, Vapour check plasterboard can be applied to increase the vapour resistance of the wall lining, this product is Kingspan Kooltherm K118, which contains an integral vapour control layer which is the use of a layer of polythene sheeting. You can also apply two coats of Gyproc Drywall Sealer
What is a building envelope?
Every home has a thermal envelope. The thermal envelope is a structure in your home that separates the air inside of the property from the air outside of the property. This includes anything intended to keep the air inside such as insulation, windows, floors, outer walls, and outside doors. The thermal envelope’s purpose is to improve the thermal conductivity in the property and prevent heat transfer from the interior of a building to the exterior. It keep the heat in during winter and the heat out during the summer creating a more comfortable and temperature controlled environment.
What is U-value?
A U-value is a sum of the thermal resistances made up of the layers that make the entire building element such as, a roof, wall, or floor. It also includes adjustments for any fixings or air vents. A U-value value shows, in units of W/m²·K, the ability of an element to transmit heat from a warm space to a cold space in a building, and vice versa. The lower the U-value, the better insulated the building element. Working out the U-value can help achieve set by building regulations.
