Thanks. Keeping the insulation and pb separate does make a lot of sense.

Hello. My kitchen has a side extension with a pitched roof about 25 years ago, before we moved in. Upon investigation there is minimal insulation above the plastered ceiling. Above the "existing" / "original" kitchen ceiling is a bathroom. The roof space above the extension is well ventilated...

Hi I'm planning a flat roof orangery style extension. I'm looking for a fascia and ultimately a gutter system that will hide the edge of the flat roof. Essentially I'm thinking there must be a gutter profile available that is higher on the outboard edge than the inboard??? Any advice?? Thanks...

The lights are a secondary issue. looking for advice on the insulation method

Ive been thinking of that! But still wonder about the initial proposal

Hi I have a side extension to the kitchen with a pitched roof. There appears to be about 75mm of loft insulation above the plaster board. With 8 poorly fitted downlighters the thermal insulation of this ceiling is quite poor. I wish to improve it. Im thinking of simply adding 100mm of celotex...

ok Thanks to You Tube, I appear to have got the Hive up and running! BUT, what do I do with the old wired thermostat? The thermostat is not wired to the old programmer so not to the new Hive backplate. So is it wired direct to the boiler? I presume I need to remove it? So, how? Hope to get...

Hi Just started self installation of HIVE. Removed Honeywell Dual Controller for CH and HW. Found only eart, Live neutral and two other wires for CH on and HW on on pins 3 and 4. I also have a wired thermostat which I presume wires direct to the boiler and not the programmer. HIVE...

Hi We currently have a system boiler that was installed in 2007 with an open vent cylinder in the loft. We are having a loft conversion. So originally thought about a closed vent cylinder to feed hw system linked to existing boiler. Some plumbers now advising on replacing a perfectly working...

You are right about the chimney effect! Not sure what you mean about "tiles off" its a plasterboard / artex ceiling. How about I cut a big hole in the plaster board big enough to stand in to lay foil type insulation over the top of any existing. Then patch the opening and skim to new? Or as I...

No ideas?..

hi. maybe 25 years ago the house I live in was extended. The kitchen was widened and a single pitch lean to tiled roof added above. When fitting some down lighters I think I noticed there is no more than about 50mm of loft insulation above the plasterboard. The kitchen is coldish and so I think...

Thank you, most informative. Joists upstairs run parallel to the wall being knocked through. Not too bothered about a flush ceiling, but want the nibs as small as poss.

Just come back to my posting as I thought it had died - I can see it's still very much alive! Just wondering what size of nib wall would be expected / minimum ? Also, I am told you can hide a beam in the ceiling? Does this give a flush ceiling to the knock through? And how on earth do you...

Timber is better than steel in terms of fire? I also know that the beam does not know if it's a party wall or not, just like the beam won't know if it's legal or not. If I cut into the existing side wall will the beam sit on both "walls" or just "mine". Whilst I would prefer a flush wall to...

Can the beam sit on existing wall, even if it's a party wall? Most people are advising a steel goal post, but say it's expensive. What makes goal posts expensive, the material itself is not expensive and the fabrication techniques used are not complex.

Zero, ok I wonder if you could explain how that might be achieved please?

Hi 1930s Semi Detached House. Looking at extending the lounge area by 2m. This will entail knocking through and a beam installing to support the 1st floor. In order to maximise the size of the room I want the beam to rest on the smallest "stub walls" possible. So, is there a minimum length of...

Thank you!!

Thanks for a helpful reply. So, if the default setting was 20, then it could be up to 20 mins before refiring the boiler, so the rads cool. If the setting was 5, the time would be reduced so less cooling time? I accept the poor flow needs sorting. Thanks.
