Semi basement - 50% in ground, has 3 small 1m2 windows at ground level. Tanking slurry applied to walls. No leaks - was left over 6 months. I have studded the walls (leaving a 25mm gap between wall and stud framework) using metal stud and insulated between with bats, my next step is to add a...

41m2 Semi basement. Room height is standard 2.4m. Looking to get recessed downlights - dimmable. As room will be a relaxing/living room I am working LUX to be 120. 120 x 41m2 = 4920 lumens. I have been having a look at these>...

Has any one got one? Looking to install on in a basement .... but interested to know on how much more they will bring humidity into the room.

What are the main differences between the two? Basement Looking to add a VC over the metal stud work before insulated plasterboard is installed. I picked up a few of these from wickes...

I have a floor (above a basement) which is constructed using Block and Beams. Under the B&B will be 25mm of insulation, Rockwool RWA45. Above will be 25mm Celotex rigid board, membrane sheet, UFH pipes and then 50mm of liquid screed. To the side of the area in question is backfill (around the...

I have placed an order online for x25 boards of 37.5mm Celotex PL4025 Insulated plasterboard. However, the company I ordered from has now informed me that the item sent will be Quinntherm QL Kraf. Looking online the Thermal Conductivity is the same on both products mentioned, @ 0.022 W/mK...

I may just do that. My stud will be 100mm, u left an additional 100mm where the UFH pipes have been laid. So mechanical fixing into the 50mm will be an option. Have a few other things to get on with so will let it dry out further.

Any one please?

50 days for fully cure for 50mm. However will/should that stop me from carrying on the metal stud work? I just need to stick down the metal U channels to the floor using adhesive. As long as the top of screed is dry it should be OK to proceed? I don't intend to switch on the UFH or tile just...

Yep, Glue. Something like: HB42 adhesive Metal stud frame, floor to ceiling. Not fixed directly to basemen walls to prevent the tanking from being penetrated with screw holes. Top of metal stud will be mechanically fixed.

I had 50mm of liquid screen poured last friday morning.... so it has been down approx just over 4 days. Semi basement - one third of basement is above ground - and it has 3 small windows. Temp down there at the moment is about 10 degrees. I popped my head in earlier and I can still see some...

I am planning to have a drinks bar installed once I complete fitting out a room. Regarding UFH, would it cause an issue of having UFH pipes running below the drinks cabinet? I plan to have one mini drinks fridge also. Majority of drinks would be kept 4ft+ off floor level. No food to be...

Was purely from googling ..... feels like my head is about to explode :D. Any suggestions on my previous post?

Understood. My plan is to add an extractor to help with the ventilation. The basement is 2/3 in ground, 1/3 out, it has 3 windows with trickle vents to again help with ventilation. If needs be I can install a dehumidifier. Option1 50mm rigid board against the internal walls. 50mm metal...

Basements are generally known to have a higher humidity/moisture level. In addition, XPS comes in at a lower cost that PIR, hence the question.

I am planning on insulating a basement. Would XPS be a suitable product for this as it has a low moisture absorption and tolerance of wet environments (v PIR). Basement walls are uneven so would rigid board be a hassle to fix? Planning to use adhesive to stick the boards as I do not want to...

Would this work. If I lay standard bricks (76mm height, 102.5mm depth) along the walls around the perimeter of the basement (where the metal studs will eventually attached on top) Install DPM and perimeter insulation I can then use this as a border area to install the UFH pipes and for the...

The completed stud work will be 100mm away from the walls. I then plan on installing the UFH pipes a further 100mm away from stud walls. Area in question is a basement, hence the metal stud route. I do not want to compromise the tanked walls by using conventional timber framework.

UFH pipes and Liquid screed at approx. 50mm to be poured in the next week or so. I then plan to build stud walls using metal studs. The tracks for the metal stud will need to be fixed in the floor and ceiling. Questions: How long should I wait for the screed to dry out before fixing the...
