Best brand of loft ladder for air tightness

[gwebstech]

Hi

 

Im just wondering what brands of loft ladders youve used that have helped you pass air tightness tests

 

ive seen a decent loft ladder for about £120 and it says its airtight, but not by how much. Ive seen some others by wellhofer that seem to be really good on the airtightness but theyre a lot more expensive. Im just wondering if you guys had any previous experience because i realise this is just one part of the air test, a house is only as good as its weakest link obviously but if cheaper ones have passed, then i dont necessarily need the more expensive one.

 

thanks for any help

A separate aluminium ladder, plus DIY hatch. See my post in this thread:

You need to choose a ladder that doesn't oversail the hatch when retracted, so it doesn't foul the hatch - or mount it higher than the loft floor level to provide clearance, or choose one normally intended for a hatch on a vertical wall, which will fold entirely out of the way.

I use  access panels  on-site 

sometimes as mad a a dozen on one ceiling So they have to be pretty airtight They are also one hour fire rated (metal)

Massive array of sizes 

I would use one of these and buy a cheap lift ladder separate
