Product description

❑  Hinged loft hatch: Slim, contemporary frame with flat lid. The frame is fitted with compression seals to control draughts between the frame and the lid. When closed, the lid is compressed against draught seals. Easy to open and close with a simple turn of the catch. Made from white injection moulded plastic and needs no decorating or maintenance.

Insulation and U Values explained

❑  This loft hatch has a choice of three insulation options. The thermal efficiency of insulation is defined by its U Value, the lower the number the more effective the insulation.

The insulation values for the loft hatch range are listed below by model reference:

❑  PD35 - U Value 0.35 (Complies with Part L of Building Regulations)

❑  PD25 - U Value 0.25 (exceeds Part L of Building Regulations by 20%)

❑  PD15 - U Value 0.15 (exceeds Part L of Building Regulations by 80%)

Part L of Building Regulations

❑  Please note the current building regulations for new build properties require hatches to have a U Value of 0.35. You are under no obligation to match this, however, a well-insulated loft hatch can help lower your heating needs and lessen your heating bills and Carbon emissions.

Compatibility with loft ladders:

❑  Please note due to the increased insulation depth of the PD15 if you wish to use this hatch with a loft ladder a distance of at least 250mm deep joists/timber plant combination will be required, if less than you will have to raise the ladder fixing point, with a timber plant.
