Yes, really. While over on stuff.co.nz this week I’m talking about the unexpected bonuses of housesitting (and a little on the downside of the constant packing and repacking), we’re still insulating. This time, downstairs with a great new (to New Zealand) product, DriTherm, again from Knauf. It’s part of the Earthwoold glasswool range and is specifically for masonry walls and cavities.
If you’ve been following along a while you’ll know that we have 50mm of ClimaFoam XPS on the outside of the blockwalls, and now with the DriTherm on the inside, we’ve bumped our Rvalue up to R3.3. With the added insulating properties of the block walls we should be toasty warm down there now. And I should add dry, cos while we’ve made sure to seal out the moisture in a bunch of ways, it’s nice to know the DriTherm won’t transmit water into the inner leaf as a double check. While we don’t need to dampen down the sound much on the wall that’s effectively buried in the bank, DriTherm provides great acoustic benefits too so hopefully those gleeful screams of The Lego Engineer and Destruction Specialist celebrating finally having their own lawn, will be damped somewhat.
Like the standard Earthwool glasswool we used upstairs, this stuff is super easy to deal with. All it takes is a measure, cut and place and it’s all done. I have to admit that it did take me longer than upstairs simply because DriTherm is stiffer and so doesn’t provide as much opportunity for measuring by eye – which is of course, my preferred method. The rigidity comes from its silicone treatment and because of that you can see every cut, nook and nick, so I had to get busy with a straight edge and measuring tape which simply takes more time. Once you’ve cut it to the exact size however, it just stands up nice and neatly in your chosen cavity until you cover it up. Job done.
