Composite Panels

We manufacture our own composite panels, the profiles are shown below and insulation up to a maximum of 100mm is available.

AS35/1000 PIR Roof and Wall Panel

Fire Performance

Wall (Two hour fire resistance)
AS35/1 000 fighter Insulated Panels are tested to LPS 1181 EXT A-i 5, BS476 Part 22 Fire Resistance, giving 125 minutes integrity and 20 minutes insulation. Panels must be vertically laid, main fix every valley with external stitchers at 300mm ctrs. No Internal stitchers required.

Roof and Wall
AS35/1 000 PIR Insulated Panels are tested to LPS1181 EXT-B. Panels must be laid vertically, main fix every valley with external stitchers at 450mm ctrs. for roof panels and 300mm ctrs. for wall panels. No internal stitchers are required.

AS35/1 000 Insulated Panels side lap joints incorporate a standard factory applied seal which assists in air leakage control and site build quality. Insulation quality and continuity is factory controlled providing no condensation, thermal bridges or moisture risk.

AS35/1000 Insulated Panels combine factory controlled thermal performance with an airtight joint system, to provide specifiers and contractors with confidence and a secure method to meet the new Building Regulations.

AS35/1 000 Insulated Panels are manufactured using CFC and HCFC Free Technology producing a panel with zero Ozone Depleting Potential offering designers an environmentally responsible product, with a life expectancy of up to 40 years.

AS35/1 000 Insulated Panels are fully compatible with Steadmans wide range of pre-engineered construction products, purlins, gutters, flashings, rooflights, accessories and fixings.
