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)...

JohnD - yes I will be organising crane to lift them! Also, roof space is to be the master bedroom!!! Thanks for your reply.

I have been quoted a cost of £3000 for manufacture and delivery of the trusses - is that reasonable?

Hello... I am currently swithering on whether to use proprietary attic roof trusses, i.e engineered attic trusses from truss manufacturer, or whether to go down the route of cutting and manufacturing the roof on-site without involvement of a truss manufacturer (though obviously with...

Unfortunately space is at a premium in this instance as such no lobby otherwise that would have been a nice solution.

Hello... I am designing a house with a Main Bathroom accessed obviously from the hallway. The thing is though, I would like to add a second door entry into the bathroom from a master bedroom that shares a partition with the bathroom. Obviously this would create a bathroom with two doors and...
