Hello.... I am considering buying a co-polymer cornice (140 meters) to fit throughout my home and am curious about my fixing options. The cornice in question is found at: http://www.toolstation.com/shop/Structural/Coving/Classic+Coving+WT11+165mm+Wide+x+2m/d210/sd3285/p48131 I...

Thanks D_Hailsham, gas4you, and snb... Writting my questions/thoughts and reading your comments and questions has pretty much sorted my concerns about the results I was arriving at and I now feel quite trusting of the results I now have! D_Hailsham... I found where the magic "multiply by...

Thanks snb... Does that mean that if I install larger radiators that I can then run the overall system and boiler at a lower temperature thus optimising as far as possible the efficiency of the boiler? As I understand it a combi boiler is more efficent (or its efficiency is more utilised)...

Thanks gas4you... The 4.8m wall and one of the 3.8m walls are external with the external 3.8m wall having a french door in it. The door is 1.8m wide by 2.3m high thus an area of 4.14m2. I think one of the things that has been making me question the results of Method 1 is that I am used to...

Thanks for your reply D_Hailsham... You are right to pick up on the apparantly poor u-values of the floor and ceiling. I should have said, the house is three floors with the room that I have used, Bedroom 1, being on the 1st floor and as such it has a heated room above it and below it, thus...

Hello... I have been working out the heat loss for rooms in a new build (140mm timber frame with 140mm insulation, cavity, 100mm block and render) in order to specify correctly sized radiators but I am getting very different results depending on the method that I use. Method 1 is where I...

Hello... Nearing completion of building a house and I asked the roughcaster to provide a wet cast render (west coast of Scotland). Using grey cement and 6mm granite chips he chose to apply a drycast (pebble-dash)! Putting aside my anger at this I now have a situation to somehow fix, unless I...

Hello... Two questions.... (1) - If I had a 1 cubic metre hole and I wanted to fill it with Type 1 aggregate (compacted down!), how many tonnes would I need? (2) - If I had a 1 cubic metre hole and I wanted to fill it with Asdug (compacted down!), how many tonnes would I need? Any...

Excellent - your information answers my questions perfectly. Thanks Richard C.

Structural Engineering Question.... I am curious as to what the difference is between a Universal Beam (UB) and a Parallel Parallel Flange Channel (PFC). I get the impression a UB is like an 'I' beam and and PFC is like half an I beam (that is, the letter 'u' lying on its side!!!) Also...

Thanks JohnD.... I have posted additional information at foot of my original post, i.e. location = Dunoon on River Clyde (30 miles West of Glasgow) as well as a link to a section of the house...

I am trying to work out which material to use to clad and felt a new roof on a new build house that I am currently planning... I have to clad it but what do I use, ply, osb, sarking board? What is the difference between them? I also have to felt (or equivalent!!!??) the roof though am not...

John D - thanks for your reply - couldn't work out the need for counter-battens, but as usual the moment it is explained it makes perfect sense!!! To be honest I am learning on the run... I am using cladding as I know it is a requirement within the Scottish Buildings Regulations... I have...

The roof pitch is 37 degrees.

Hello... I am curious as to the requirements in Scotland on roof construction... Proposed roof construction is as follows (bottom-up): trusses(rafters), 9mm cladding (plywood, osb, etc...), felt, counter battens (vertical) - or does this go on before the felt?, battens (horizontal)...
