Hi Guys, Thanks for the reponses. Both are very helpful. The house is a mid - late 70's house and the dining room looks like a bit of a self build extension at the back of the house. The overall quality is not great. Both have mentioned a concrete slab but as far as i can tell...

Hi guys, So.....dining room is at the back of the house, leading on to the kitchen and then the hallway. Dining room floor is currently 30mm higher than the rest of the downstairs. Plan is to tile right the way from front door to dining room (which provides the back door). After what...

I have a load of 32mm zinc plated (silver) drywall single thread screws with a self starting point. i think these are for metal frames, rather than timber stud walls. I intend to use these to fix 12.5mm plasterboard to timber studs. Will these suffice? Or should i buy slightly longer...

I have a lean to roof that runs away from the house at a pitch of circa 30 degrees. I have installed 100mm Kingspan between the rafters using a friction fit. I need to install 35mm Kingspan under the rafters, an 'under drawer'. I intend to fully tape every single joint on this under drawer...

For anyone else undertaking a similar job (lean to tiled, vaulted roof and ceiling).....I have spoken to Celotex and been advised of the following: 1) If you use breathable membrane under your tiles, you do not need to ventilate. By ventilate I mean add soffit vents and ridge vents (if...

Newly built vaulted tiled roof using breathable membrane. Rafters are 145mm deep. I intend to use 100mm celotex between rafters (leaves air gap of 45mm). Will then put 25mm celotex under rafters. Does this sound OK? I dont get the need for the air gap? If warm air gets through the...

Thanks Noseall. Very valuable information - much appreciated.

Is this Vapour Control barrier a Buildings Reg/required requirement? Also, would you advise just celotexing between rafters or between and below?

Thanks noseall. It is a lean to roof - slopes from house. Old flat roof completely removed and started afresh. The roof is now complete with 2 roof windows. Just need to celotex and then plasterboard. I have been in contact with Celotex and they recommend the following: I) Celotex...

I am converting a single storey flat roof extension to a pitched (slanting from house) roof. I plan to use celotex insulation between the joists and then screw plasterboards into the joists. Is there such thing as hot/cold roofing systems with a pitched roof and with vaulted ceilings...

Currently have a single storey flat roof extension, which I am planning to convert to a sloping pitched roof (from the house), with 2 small GEOM roof windows. I am confused by all the hot/cold roofing systems and would like to achieve the best result. I will be using roofing membrane under...

Hi guys, Installed a Salamander pump 2 years (CT50 I think). Has made showering much nicer! However, recently it has started stuttering i.e. on/off, on/off, on/off....and annoyingly only at the temp which is comfortable for a shower LOL Any ideas what could this be? i was thinking it...

Hi All, Some advice please..... I am building a shed from scratch and have had some 'Structurally Graded c16 carcassing' timber delivered from B and Q. However, I am sure I ordered the 'treated' version of this, which is suitable for exterior purposes. What has been delivered is the...

Before making this post I contacted B and Q to enquire whether their standard aerated concrete blocks are suitable for outdoor use. Head office called me to confirm they are suitable and painting with masonry paint will be sufficient! So many different opinions on this subject..........

Thanks Virgilns, I have considered rendering but have no experience or even watched someone doing this. Is it something a complete novice would be able to do or is it best not attempted by the novice? Unfortunately, cash is a bit tight and so I do not want to pay someone to render for me.
