Conservatory Cavity Wall Insulation

May 03, 2004 9 Replies

My new conservatory has a 2m high cavity wall but unfortunately no insulation bats were used when it was erected. What are my options for cavity insulation? At this stage the window boards are not fixed so the cavity is open all the way round.



Can I get some form of loose fill insulation & do it myself or do I now have to go for the pumped stuff?


Is the conservatory floor false and well clear of the ground, and with a damp proof course in the walls ? If so you may be able to insert slightly compressed Rockwool slabs down to just above the DPC level without too much difficulty.

You can push glass fibre insulation batts down into the cavity from above.

How do you get them past the wall ties?

See my answer to "G&M" above.

I would forget about cavity insulation and go with an insulated plasterboard.

I'd do both. You can drill and inject loose insulation with great success. Well worth it. Then dry line with the usual suspects.

You need all the insulation you can get to compensate for the dreadful glazing losses

In strips from above, manipulating them sideways underneath the ties.

You've been listening to IMM a bit too much, methinks ;-)

This is assuming that the ties are all vertically aligned and that there are no snots in the cavity. To move down through the cavity without snagging, the batts would have to be significantly narrower than the cavity, in which case the batts should be secured against the inner leaf with clips. This raises the question, how do you get them onto the wall ties?

I never do that, Hugo.

In the one that I did, there were no snots (I made sure of it) and the wall was not that high anyway.

I made a sandwich of art card and fibre batt to slide into the cavity, then when position was right, slid out the cards. The batts spring into place. Fiddly, but it works.
