Insulated, airtight, plasterable access hatch?

[tommyt11]

Has anyone managed to find an off the shelf access hatch that can be plastered up to and on top of, that is also of a high standard of airtightness AND has some level of insulation incorporated? I am doing a basement conversion that has service hatches to rest of ground floor underfloor crawl space; house will be fixed up with oodles of insulation and MVHR hence I need something good here. In the absence of finding something off the shelf I will just get a well-gasketed plasterable hatch then inside it fix up a PIR inside a 3x2 carcass that can be screwed or similar to the inner reveal (which will be quite deep).

 

Thanks,

Tom

Hi @tommyt11

Often have had to buy a regular one and insulate it! Or on the last 2, build my own, and insulate them, and air tightness by compressing a gasket on the door stop and fixing shut by a latch or two.... 

 

Good luck
