Solid Wall Insulation

Here's more information form the government energy website - http://www.energysavingtrust.org.uk/Home-improvements-and-products/Home-insulation-glazing/Solid-wall-insulation - it predicts savings on heating of about £380 a year. You might be able to get a grant towards this.

I've just phoned the manufacturers for Wallrock. They're sending me a sample. Cost is about £50 for 7.5 sq mtres & adhesive about £30, but not cheap. B & Q sell it & reviews on B/Q website are pretty good. Maybe worth a try....

I'm just putting up thermal liner now on my external walls, agreed it is a bit of hassle but i think it will be worth it in the end. B and Q do it at 50 quid a roll but you can get it online for around 40 quid, worth saving a tenner.

There's a video on the company website showing how to apply the liner. But it also says you need a liner paper on top of the thermal liner. The cost all adds up, but as i have shoddy walls they'll be covered up nicely. Ill have to wait till winter now to see the benfits.

'Insulation wallpapers' and the like are pretty much useless as actual insulation.

You're trying to get something for nothing.

Sempatap is sold as mould growth inhibitor. It stops mould growing by raising the wall temperature a few degrees. But as an insulant it's useless. That claim below that it will save 'vast amounts of money' is laughable, I can't believe he hasn't been banned for that post.

If you want an effective insulant that will actually save money on your heating bills you either need to go thick (XPS, EPS and Phenolic Foam) or expensive (Aerogel).

If it's cheap, and thin, don't bother.

Just posted this on another thread:

Be careful. A solid walled building needs to breathe. If you stick a load of junk onto the wall, it wont breathe and the house will end up wetter than before, mainly from condensation related problems. This is a huge issue, too hard for one post. In short, the solution is this ...
Clean the wall of anything back to bare brick.
Use a steel frame system - from Protektor Uk, or British Gypsum system
This allows pipes and wires to run behind
Step it off the wall by about 20mm to allow a breathable air gap.
Insulate - but you must use sheepswool - NOT mineral wool which suffers from condensation
Then plasterboard as normal.

Then google the latest SPAB research on insulation of old buildings - they have just released a superb research report on this - in which this system is referenced. I'd include a link, but as a newbie I'm stopped from putting links up - which is a pain... but maybe mods will let me.. Mods - please email and I'll put the research link up for all to see the effective u vales.

Warning - most of the systems sold by independent companies are snake oil - DONT buy them.

There's some interesting comparisons in there between key differences with old and new houses.
