 Fire rated Bespoke Loft Hatch
This high quality "Made to Measure" Fire rated hinge down steel loft hatch has a sleek design for the contemporary modern house. There are no projecting hinges or handles, just simple clean lines.

Construction and finish
The hatch is Powder coated 1.2mm zintec steel smooth white (RAL 9010) maintenance free finish. The loft access door requires no painting and projects into the ceiling space a mere 8mm.

The hatch frame depth is 63mm (going up into the loft).
Please note if it is less than 450mm from the hinge to the lock side the depth of the panel and insulation is reduced to 30mm to enable it to close.

Insulation and thermal efficiency
The Part "L" compliant loft hatch is insulated with 50mm of exposed fire resistant mineral slab.

The loft hatch has a neat steel, silver tri-drive budget lock with a built in chamfer to give a smooth closing action.

In addition, the loft door has a concealed draught seal between the mitred frame and door, providing a phenomenally high air seal rating. This virtually eliminates vapour ingress and/or warm air leakage and it also makes for easy decoration of the ceiling up to the edge of the loft door surround.

Lock options

Choose from:
1) Standard Tri-Drive lock - a high quality lock with integrated internal O-Ring seal for improved airtightness

2) Key lock - a neat key operated lock. Useful for situations where access to loft space needs to be restricted e.g. communal areas or rental properties
Fitting instructions are included.

Both lock options operate a chamfered cam which applies compression between the door face and the seal on the frame to maintain airtightness.

What measurements are required to make your hatch to the right size?

Please note for timber joists with plasterboard clad ceilings the opening needs to be lined with a minimum of 9.5mm plasterboard. Thereafter measure the length and width of your loft opening (between the ceiling joists and the trimmers / cross members). Deduct 5mm from each dimension, this makes an allowance for your loft opening not being exactly square. Please double check your measurements as these loft hatches are made to order and cannot be returned. If you are in doubt, please call us on 01937 325 325 for advice.

Delivery time

Quoted in working days (sat/sun not classed as working days)


Your hatch will come with installation instructions and fixing screws. Simply offer the hatch up into place and fix into place. The frame has screw holes pre-punched.

Environmental information

The loft access trap insulation is CFC & HCFC free, ODP zero and compliant to Code For Sustainable Homes standards of a GWP (global warming potential) rating of zero. Please note for timber joist/plasterboard clad ceilings the opening needs to be clad with a minimum of 9.5mm plasterboard prior to taking any measurements.

Need a Fire Rated loft hatch bigger than 900x600mm?

Our maximum size using this design is 900x600mm. Please call to discuss if larger as we have a test for a 900x900mm size to BS 476 Part 22, but the product structure & price will alter.

Q How do I work out my clear opening?
The clear opening will be -75mm on your non hinge side and -25mm on the hinge side. E.g. a hatch 775 x 560mm (Hinged short side) will have a clear opening of 700 x 535mm +/-2mm. The same size hatch hinged on the long side would have a clear opening of 485 x 750mm +/- 2mm

Q My opening is out of square, is the 5mm deduction enough?
A Please call for individual advice on the matter.

Q Does the door sit flush with the frame?
A To ensure a tight air seal the door projects marginally on the lock side, however over a period of about 3 months this will reduce by approx 50% to roughly 2mm
