YBS ThermaQuilt - 32mm Multi-foil Insulation

YBS Thermaquilt 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.

Product Applications

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

ThermaQuilt is a highly effective multi-purpose product that 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.
