Manthorpe GL280F 1 Hour Fire Rated Drop Down Loft Access Hatch

The Manthorpe GL280F 1 Hour Fire Rated Drop Down Loft Access Hatch is designed for installations where fire protection and airtight performance are a key requirement. Manufactured from durable powder-coated steel, this rectangular drop-down loft door provides 1 hour of certified fire resistance, helping meet safety standards in both domestic and commercial buildings.

The hatch includes draught seals on all four sides, ensuring an airtight barrier when closed. This helps to reduce the risk of moist, warm air entering the roof space, while supporting compliance with Part L of the Building Regulations. The GL280F is also tested to meet BS leakage rate recommendations and the L2A air permeability threshold of 10m³/h.m² at 50Pa, confirming its suitability for energy-efficient buildings.

Insulated with mineral wool, the door delivers a strong U-value of 0.35 W/m²K, aiding thermal performance and reducing heat loss. The lightly textured white finish is easy to clean and can be painted to suit surrounding decor. A budget lock and T-key are supplied for secure, controlled access.
