Product description

When designing the "SD", we didn’t just set out to pass a 60 minute fire test. We wanted to give you the best fire rated loft hatch could. In addition to being fire rated we also wanted to provide industry leading levels of insulation and air tightness.
In the SD you’re getting a high quality steel hatch following a simple modern design featuring clean lines which is built to last.

Material – Zintec steel / Powder-coated
Colour / finish - White (RAL No. 9010 – satin) / Smooth, maintenance free finish. The hatch is supplied ready to fit, no decorating needed.

Insulation, air test and thermal rating

•    65mm Mineral wool insulation
•    U-Value of 0.32 W/m²K – Exceeds the requirements for Part L Building Regulations which require loft hatches to have a U-Value of 0.35 W/m²K (Lower is better)
•    Air tested in an independent UKAS accredited test house with superb result of 0.76m3/hr @ 50Pa
•    UKAS accredited air infiltration test compliant for loft access hatches without the use of sealant to the external frame, saving you time when fitting.
