Gone West

A lot of NT pathways are made of hoggin. Easy to use and if it sinks a bit you can just top it up.

Timber I-beam portal frame using 15mm OSB3, 350mm Icynene with plasterboard and skim. No tapes or membranes at all. Airtightness was 0.47ACH.

I hope so, as I'm gradually going over to Dewalt 18V XR tools.

Safe, but you might run out of hot water.

Just thinking about it logically, I would turn both off and see what the effect is.

We're trying to keep up. https://www.beba-energy.co.uk/solar-panels/thanet-earth/

We didn't use decoupling mat but did use flexible tile adhesive. The concrete had been down five years before we tiled the downstairs and we didn't have UFH.

IIRC it was a rodding elbow and I drilled a hole in the centre of the rodding cover for a 50mm 45 degree bend which I bonded on somehow. It was eight years ago so the details are a bit thin I'm afraid.

In our downstairs wetroom we were tight for space and I used a short, straight WC connector into a 90 degree bend with a 50mm AAV vertically off the bend.

I think it depends on how obvious the work is, that you plan to do. Are you detached, do you have nosey near neighbours? Most people don't know the difference between Planning and Building Regs. If you think there's a good chance someone might dob you in, then be careful. If not then I doubt anything would happen.

The wind has never moved it. I've not tried hosing it because I didn't want water going in the vent slots. I have brushed it with a broom and it was ok. To a degree it is held in place by the slot in the fascia. I won't be altering it for the time being.

Nope, makes it easy to remove though. 😀

Ours are fitted like that where the 1970s cavity wall alterations were made. Apparently our uPVC soffits replaced asbestos ones as well.

The twin cylinder softeners like Harvey, etc regenerate when required by switching over to the other cylinder. I had different models in the different houses I lived in, in the SE. They were all ok. Fortunately moving to Cornwall means I don't need one any longer.
