We are now half-way through the installation of the Pavatex internal wall insulation. Work has been completed in the dining room, just the living room to go. The insulation is 6cm thick and is installed by screwing onto the wall, using insulated screws to fix it in place. We had wondered how it would look to add this extra thickness internally - but even before plaster has been added on top it looks great. It may be partly psychological - but the room does feel cosier already. Certainly, not having a radiator in the dining room (temporarily removed) hasn't been a problem - the heating drifting in from the hall and kitchen have kept us perfectly warm. Not only that, but since the floor insulation has been finished we no longer have any visiting slugs! 

Given that it looks like the adding internal insulation isn't going to look 'wrong' in the house, it does make me wonder whether we should have thought more seriously about going for completely internal insulation rather than external insulation on the side wall, and internal on the back and front. However, the external insulation is thicker - 10cm - and we wouldn't have wanted that thickness internally. It will be interesting to look at the costs of the external vs internal insulation when all the bills have come in.

Hi Tina

 Thanks very much for sharing this. I am interested in this pavatex product for our house (1926 solid wall detatched in Liverpool) and will probably test on one room first. Did you use the PAVADENTRO product from Pavatex? They seem to do it in 60,60 and 100mm depths. Did you choose 60 to fit the house I guess? (door finishes etc)

Finally, did you just plaster over it with normal Board Finish plaster or anything special? The pavatex product appeals because of lack of VOCs etc as well as thermal performance, so a shame to bring them in with any plastering....

Many thanks
