Roof Hatches

The SRHA is a premium, single-leaf aluminium roof access hatch, hand-made in the UK to deliver industry-leading thermal efficiency, high security, and safe, gas-assisted operation.

Certified Performance & Insulation:

• Thermal Rating: Achieves an industry-leading U-value of 0.43 W/m²K, thanks to 50mm twin foil backed PIR insulation.
• Airtightness: Certified to Air Permeability Class 4 (tested at 100Pa to BS EN 12207), ensuring minimal air leakage and excellent weather protection via dual EDPM seals (Quadruple seals available).
• Insulation Quality: PIR insulation is CFC & HCFC free with an ODP (Ozone Depletion Potential) and GWP (Global Warming Potential) rating of zero, maintaining the thermal integrity of the building.

Construction, Security & Operation:

• Construction: Fabricated from durable 3mm single leaf aluminium with hardened steel hinges, supporting a live load of 200Kg per m².
• Safe Operation: Features twin gas assisted struts; one strut includes an auto-lock open feature when fully extended, preventing accidental lid closure without the need for an additional stay.
