cold roof

New kitchen extension which has pitched warm roof. Do I just need to 'celotex off' between each rafter to stop cold air coming in ?? (as ceilings will just be boarded- no insulation req ) Also above glazing a similar scenario ?? see pics second image is where eaves are shut off due to box gutter

Hi I have an old flat roof which is failing. The roofers have stripped the felt and replaced some of the OSB. Underneath there's a (to my mind, not well constructed - e.g. gaps in insulation/no foil taping) cold roof, using PIR (I'd guess 75 or 100mm). The roofers have put on a VCL and PIR...

I am about to start building the subdeck for a standing seam room, I'm getting splinters while I still procrastinate zinc, steel etc. I have been discussing the supply of Standing Seam from Pagurek with Patrick who has been very helpful but I'm after some pictures or advice from those who have...

Hello, We’re figuring out the design for our crown roof - something like the attached image, where we have a flat part on the top (with appropriate fall to stop water pooling), and then it would be pitched on three sides. Would this kind of roof be better as a cold roof or warm roof? I...

Hi, I have a single-skin brick extension with a concrete flat roof from the 50s/60s that I’m getting re-covered. The concrete roof overhangs the exterior by 100-150mm. I’m trying to decide whether to go warm or cold roof. I originally thought warm but now I’m concerned about potential...

Hi, I’m having difficulty finding an answer to what seems a simple question. What is a typical depth for a warm vs cold roof in a rear extension? i.e the measurement from the underside of the ceiling to the top of the roof. Thank you!

Hi I’m hoping to improve the loft insulation of a cold roof of a large wood clad, timber frame bungalow that is currently poorly insulated and struggles with heat retention. It is currently largely single glazed (I’m working on secondary glazing with Magnetglaze Extreme Pro and 4-6mm Perspex)...

Hi Guys, I am about to put in my insulation between the rafters after my electrics first fix, The question being do I put the insulation in so they are flush to the bottom of the rafters or can I put them above my wiring as long as I leave my 50mm air ventilation gap? There will be 50mm pir...

Hi, This is a small flat roof that joins to the house and main pitched roof. Some background info: It has never had any insulation between rafters and doesn't have insulation on top. Timber roof joists/rafters with timber furring. Then plywood and then torch on felt. We discovered the...

One of the many little gems I've come across when renovating my house is that my flat roof is a cold roof - the insulation sits directly upon the plasterboard with a gap above between the insulation and actual roof. I'm contemplating converting this to a warm roof as I may as well do it now...

Not sure where to post this query, but hope someone can help. I've mostly built a garden studio, insulated, cladded and now onto the internal finish with the vcl, but am unsure how to approach the electrical sockets, window frames and doors. How do you get around sockets, frames, fixings for...
