I got one this week for a 150sqm house for 6850. Airtight on a wide cavity wall build. Not sure what your spec is though.

About the same as I got for a 3000sq ft hse, windows, door and roof.

or the finishing trades and second fixers punch so many holes in the fabric that it ends up being the same as if not done. Electricians are the worst. Do the hand test when they are finished - if theres air whistling out of the sockets, someone has been naughty. Happens more than you'd ever believe. Also remember that the good materials for sealing are very spendy, so if a quote is suspiciously low, be suspicious.

Where were you reading this? And what has it got to do with air-tightness?

best quote i recieved (out of 5 professional contractors) was €3900 for 270sqm new build two-storey including 2No. air tightness tests - so i would say that you are in the right ballpark...

That price was also for all the insulation.

Hi Folks - I have noticed that everyone replying has a new build - what does air tightness mean for a house built in 2006 - can I do anything?

Yes, but you won't know until it's tested

That's why professional builders fit airtight membrane up to 1/3 in to the insulation and leave that 1/3 of top layer for communications, but there's just a handful of builders who know how to do it right!

You can update your house and make it up to date standard.

ok so had a read of a few websites and for a currently occupied home I can't see exactly what substantial improvements can be made apart from the obvious removal of draughts or am I simplifying it?

do you think it is worthwhile investigating it further?

Yes.

Imo and experience, lack of air tightness is the number 1 reason why houses, in our mild but windy climate, are cold, uncomfortable and costly to heat. This holds true for even recently built houses and renovations where no thought has been given to the subject.

This membrane prevents from mould in the way it don't let air condensate inside the insulation and/or other parts of structure.
