I'm adding a fake chimney breast to my living room which will hold a wall mounted bio ethanol fire: and above that, a TV. The finished thing will hopefully look look exactly like this: The fire itself will be bolted to the wall, with the chimney breast built around it. I've seen false...

I had no idea this was possible with ceilings. I'm an aerospace engineer and wings are huge torque boxes. Essentially top and bottom skins are glued onto a grid structure. The bottom skin is in tension and the upper skin in compression to support the load. Similar to a hollow-core door where the...

Good stuff - thanks for your help. Much appreciated!

I respectfully disagree. If I hammer on the internal wall and it's totally detached from the outer structure, the internal walls and ceiling vibrate and the energy is dissipated. Insulation between the outer and inner structures helps damp the vibrations. If I have the ceiling attached to the...

Thanks for the reply! Unfortunately I can't attach any of the new structure to the old as it will transmit sound (flanking sound). The new ceiling has to be totally detached from the outside walls. From doing a bit of research, what I'm talking about making is a 'rigid frame' (as opposed to a...

I have a 6m x 5m garage which I’m planning to use as a workshop for tinkering on cars, playing music, etc.. To keep noise down, I’m planning on building a sealed, timber framed room-within-a-room, clad with a layer of OSB and a layer of plasterboard. The idea being that noise generated in the...

From reading up online, having the inlet vent over the bath is fine as the fan itself is outside of the 'Zone' requirements (i.e. IP ratings) so that's ok. Looked at the roof vents and they look like a great job, but I'm always wary of putting holes in the roof, especially since the pitch...

Also, the existing in-line fan has its inlet vent right over the bath - is this ok?

I've just noticed that the inline fan in my bathroom is venting straight into the attic... which would explain the dampness up there. It's also been piped in corrugated duct which was holidng about 500mm of water. Going to repipe it in solid duct and insulate it. Can I put my exhaust vent in...

Sound Isolation requires MASS and AIR in order to damp the vibrations caused by sound waves. Ideally you'd have a room-within-a-room scenario where the inner walls, floor and ceiling are all decoupled from the outer structure using compliant isolation strips, such as neoprene or EPDM. When you...

Surely water vapour is going to come from 2 places though - outside the garage (from rain, mist, dew, etc.) but primarily from inside the garage from wet cars, people breathing/sweating, etc. If I deal with the inside by plasterboarding, vapour barrier and insulation, I just need to worry about...

I’m building a garage which has a box profile steel roof. The roof came supplied with foam fillers which go at the ridge (underneath the ridge cap) and at the eaves, but the supplier of the roof mentioned I could leave the eaves fillers out ‘to keep condensation down’. The garage is being...

Got it working this evening. For anyone else who has a similar problem, mine was to do with the nosepiece. As you push the nosepiece down onto a surface and it slides back, the combustion chamber in the back of the gun closes up and the fan switch should come on. My nosepiece was adjusted for...

In his defense he had no gas for the gun and I didn't bring any so I couldn't have seen it working. Since it was an ebay sale I'm covered by ebay and Paypal so return is definitely an option. Just wondering if there's anything common with these nailers? Safety switches? Some little sensor...

I’ve just bought a Hitachi NR90GC framing nailer off ebay, which was an hour up the road from me, so I picked it up in person. It’s used, in decent nick (the battery clip is broken but the casing all looks clean and in good shape) and advertised as working. Charged the battery, loaded some gas...
