    Hi guys,

    Let me begin by saying I have Zero building knowledge!!

    I am renovating an 100+ year old cottage (approx 72 m2 floor area) and by renovating I mean completely gutting and rebuilding!

    I am having an air to water heat pump installed in conjunction with underfloor heating. All external walls are being drylined internally. Other insulation to current regulations.

    My question is regarding airtightness... My engineer is recommending making the cottage airtight (which he is certified to carry out).

    Is it worth carrying out?

    If I do not carry it out what effect will it have on my heating and heating costs?

    Many thanks.

    Yes IMO definately.

    If all draughts are controlled then it will greatly reduce heat loss, therefore saving you money.

    I have done a similar refurbishment in 2003. Airtightness was not an issue then but I installed the membranes. I am happy that I did, the technology works.
