Hi D_Hailsham. It is a combi boiler. It is my own house, but there is still work ongoing. I haven't installed a thermostat yet, but I will be. The temp at the moment is set to the lowest it can go (frost protection). Hi Tony. I don't know how I can get away with not paying my...

Yes. I'm not sure of the tariff, but I know that they are taking an extra £25 per week off me as I have a large debt with them from last winter. I had a bill last winter of around £1200 for 4 months use. They installed a card meter, so at least I can keep an eye on it now. The £25 comes...

Hi. I am looking for some advice on the most efficient way of using my boiler. I have a Biasi 32kw boiler and it is costing a fortune to run. I have 7 radiators on from a total of 11. I have the boiler set to the lowest level (frost protection), but it seems to be coming on a lot more...

I am working to SAP calculations for a new build. I have found out, that if I use a 100mm cavity with 50mm Celotex I only achieve 0.28, so I would then have to include some other material on the inner leaf (thermal block or insulated plasterboard). However if I increase the cavity to 110mm...

Thanks oldun. I've finally got it. Whats confusing me is the thickness of the insulation in the lintel. The L1/S100 has an 88mm wide thickness and the L1/S110 has 108mm. I assumed that it was the width of the insulation that was the deciding factor. I noticed that you said that the...

Hi. I have a 110mm cavity wall, 100mm dense concrete block on both the inner and outer leaf. 60mm of insulation inside the cavity. I have been told by the BCO that I need to either use a thermal block for the inner leaf or a dense block with an insulated plasterboard. I need to achieve...

Hi woody. So are you agreeing with the SE that a 100mm is sufficient to use. I like confirming most things on here as there seems to be a lot more knowledge from people practically doing it day in day out rather than just knowing the theory behind it. We are only 6 weeks into the...

Cheers guy's. I've just spoke to the structural engineer that I use (and is also working on this project for me as and architect) and he said that I can use the standard 100mm lintel. There is hardly any difference in the structural integrity between the two. The difference in price...

Thanks both. So it doesn't really have anything to do with the width of insulation, it's more to do with the structure of the lintel? Someone told me to just use a 100mm lintel as there's not much difference between the two in regards to the loads it can handle. Cheers.

Hi. I am just about to start constructing the walls of a bungalow and need quite a few lintels. I'm looking for some info on what I should be fitting. The two brands I'm looking at are IG and Catnic. As the building regs changed in October I'd like to know which ones I should be...

Brilliant. Thanks very much for the advice.

Hi foxhole. I don't mean that I will cut each length. If a length is 1m long I will cut the first piece of the second row at say 600mm, the third at 300mm and then maybe 700mm. I just want it to look more random than the way it states. It tells you to cut the first piece of the second...

Hi. I would like to know the best way to lay laminate flooring. I have laid it a few times in the past, but it has been the ones where they butt up to each other flush and you don't see the joints. I have now bought a product which has a bevel at the joint and so you can see where each...

Thanks very much mate for all your help. Your right in what you say, in theory most things work out, but in practice it's ridiculous. Cheers.

Hi noseall. Sorry. I just re-read from your first post. I now see that you have explained what I was asking, but I was concentrating on the pic that you posted, which is showing the cavity tray being formed straight away. I have seen the pic that you posted on a few sites, but it...

The pic that you have posted has the Radon barrier laid on top of the beam and block floor and then forms directly into the cavity tray. On the pic 3.1 that is shown on that link the Radon barrier is laid on the beam and block floor, but goes directly across the cavity. The cavity tray is...

Thanks noseall. This is what they are showing from the following link. http://www.hillingdon.gov.uk/media/pdf/l/a/BR414.pdf The way they are showing is that the radon barrier comes straight through the cavity at the same level and a cavity tray gets formed above. Is this OK to do...
