YBS ThermaQuilt - 32mm Multi-foil Insulation

Product Functions

ThermaQuilt is a rafter level, pitched roof application product, that effectively deals with all forms of energy transfer by reflecting infra-red radiation.

It is effective in winter by reflecting heat back into the building. In the summer ThermaQuilt works as a barrier to solar overheating, which reduces the need for artificial cooling systems as it prevents the accumulation of heat within the building.

ThermaQuilt can also be utilised in wall and floor applications.


Product Properties & Benefits

ThermaQuilt is a very flexible, easy to fit, multi-layer insulation thermally tested achieving a high thermal resistance of up to 2.07m²K/W for ThermaQuilt accompanied by a 38mm air cavity either side of the material.

Due to the special composition of multi-layers of insulation, ThermaQuilt effectively deals with all forms of energy transfer (i.e. conduction, convection and radiation). ThermaQuilt works most effectively by reflecting infra-red radiation. This means that not only is ThermaQuilt effective in winter by reflecting heat back into the building and cold out, but also in summer.

ThermaQuilt is a very effective barrier to solar overheating, reducing the need for artificial cooling systems as it prevents the accumulation of heat within the building.
