Looking to install a Smart home/CCTV setup once i have finished with my extension. Currently have an old type alarm, Hive for heating, and zigbee sensors switches for smart home. Looking at getting an all in one - ideally standalone system recording to a hard drive rather than the cloud. IP...

Is it a necessity to insulate over the rafters as well as in between them? As mentioned earlier my plan was to use 165mm celotex and the plaster board straight over the rafters.

Is it a necessity to insulate over the rafters as well as in between them? As mentioned earlier my plan was to use 165mm celotex and the plaster board straight over the rafters.

Rafters are 9x2so approx 225mm depth I was planning to insulate with rigid board at 165mm leaving a 60mm air gap and then plaster boarding. Is rigid board such as celotex good at keeping sound out? Other options Add a acoustic plaster board Could I incorporate sound proofing in rafters and...

Morning I measured the rafters and different points to determine the pitch. I emailed and spoke to Marley who have said as the head lap has been increased there should be minimum issues. BCO has said that he is happy as it is only off by a degree and that the area of the property is in a low...

Could I leave the polystyrene in place (50mm) and add 25mm rockwool on top? 75mm in 75mm rafter. Then membrane over - using Klober Permo Forte.

Woody I stripped roof and found a white polystyrene type Insullation. 50mm in between the rafters were the dormer slopes were. Is this type any good? I expect it to have been installed back in the 80s.

Any one? Rockwool RWA45 or https://www.travisperkins.co.uk/cavity-and-internal-wall-insulation/knauf-acoustic-roll-ready-cut-25mm-11-10m-4-x-600-26-64m2-per-pack/p/848595 Which can i use in the sloping area pointing with the blue arrows.

I am replacing the roof on my dormer bungalow this coming week. New membrane, battens and tiles. I have drawn image below. Orange = Dormer room Where i have drawn red lines is where i will remove current insulation and replace. The joists are 200mm/8" deep. I will use either mineral or...

Tile manufacturer states "17.5° Minimum pitch" I have measured degree of slope from the internal rafters using a digital measure. Degree is 16.1. Also measured using a level, measuring 12" across the rafter and the distance up. This works out to approx 3.5:12 So, I am just over 1 degree...

Thanks. Am I correct in thinking Mineral wool gives better acoustic performance?

Having the roof of our dormer bungalow replaced so will be taking the opportunity to refresh the insulation. There is current access to the dwarf walls via a hatch, but it is crawling space so awkward to work in. I think the previous owner's electrician left the current insulation scattered...

£300 a 1.5m x 50m roll. Never knew they cost so much! I have contacted Viking and Klober to clarify what the airgap should be from insulation to membrane. If a 50mm gap is still required i may just go for the Klober Permo Forte.

Nearly £200 a roll then! If using a breathable air membrane do you still need to leave 50mm gap between membrane and insulation (in between the rafters). I have 225m joists, was planning on using 165mm celotex leaving a 60mm air gap. If the air gap is not required or can be reduced, i might...

Does the Klober Permo Forte fall into this category?

From searching this site it appears what most recommend. £135 a roll is the cheapest i can find.... some places are selling at nearly £200 a roll! Permavent Max Membrane - Any one had any experience with this? 150gsm for £65 a 1x50m roll.

Hi, Any suggestions on which membrane to go for? Will be my forever home and replacing approx 260m2 of roofing so don't want to end up going for some poor quality material. Klober Permo Forte Breathable Membrane 1.5m x 50m (75m2 roll) - This any good @ 150gsm? Coming in at approx. £150 per...
