Below we cover the facts about SuperQuilt
2.2.10 Fire performance – From the KIWA BAR-19-113-P-A-UK Test report – Download it here
The Product is classified as European Classification E* (combustible), in accordance with BS EN 13501-1.
The Product has a low rate of heat release and a low rate of fire growth when ignited. The Product will melt and shrink away from heat.

8.1 SuperQuilt has a reaction to Fire Classification of Class E in accordance with BS EN 13501-1 : 2007.
8.2 The insulation MUST NOT be carried over junctions between roofs and walls required to provide a minimum period of fire resistance.
2.2.3 General design considerations – From the KIWA BAR-19-113-P-A-UK Test report – Download it here
The uncompressed Product is most thermally effective with a minimum 13 mm or 20 mm non-ventilated air cavity (formed using timber battens, structural timbers (studs) or internal metal framing profile) on both sides of the Product.
SuperQuilt is 42mm thick – to achieve its stated thermal performance, it required an air gap of between 13 and 20mm’s. To achieve this, it is recommended that battens of 38mm are used to facilitate the required air gap.
Due to the thickness of Superquilt, the RECOMMENDED batten depth, the glazing bars and the cladding, if installed to the manufactures specifications the insulated ceiling would come down around 6 ½ to 8 inches. Therefor apart from wooden conservatories, almost all companies who install Superquilt use 25mm battens – This makes it impossible to achieve and maintain the 20mm air gap required and recommended for the customer to gain the stated U-Values and performance claimed. Without the 20mm air gaps, the risk of condensation is greatly increased.
If you look at the photo below you will see Superquilt fitted with 25mm battens. The quilt is so thick that it is actually resting on the cladding. If the quilt touches the cladding, it stops insulating and actually acts as a conductor which creates hot / cold spots on the conservatory ceiling. Cold spots on the inside of the ceiling can lead to internal condensation.
