    I've been looking at the various options for airtight loft hatches - I need two - with the main loft having a pull down ladder fixed to the small area of floor above (rather than the fixed to the hatch!).

    Then the old mind wanders and ponders on how easy would it be to simply make them myself? Framing up the opening - simple ... hinged lid - not exactly difficult, just take my time to make it look good .... airtight seal - well, they are readily available and will require a groove cut and then a lock (or locks) fitted to ensure the hatch closes firmly onto the seals. I would also look at creating sides to protect the insulation around the access and work out a safe way of insulating above the hatch, but that would be needed even if I bought them.

    Anyone else gone through the process? Any drawings available??

    Many thanks, JT

    Easy, probably self adhesive strips would be OK, always use in conpression. brush seal ones are nice too

    I have two traps in the same hole, one poens down, the other upwards and both are draught stripped, the upper one is insulated, I have 450mm of loft insu;ation and a 50mm void.

    Interesting option Tony - the lower one more decorative, the higher one with the cam-type locks to pull down onto the draught stripping. With both having gaskets / draught strips we should be airtight enough! Package up some glass fibre to sit on the top flap so I can access the loft without getting a face full of fibres - sorted.

    Many thanks - Jonathan

    I got this same problem that I am yet to solve.

    One option I thought of was to screw the loft hatch closed, as removing a few screws 1 or 2 times a year is not an issue.
