How to mount an external door when using an insulated slab?
Iceverge replied to zzPaulzz's topic in Timber Frame
Cut out some of the XPS to allow the door frame to be partially supported by the concrete- 6 replies

Have thermal stores had their day?
Iceverge replied to Workerbee's topic in Boilers & Hot Water Tanks
I've done both. UVC and TS. From trial and error real life living the UVC will deliver useable 40deg water until the average temperature of the tank is about 30 deg. The TS is all out of ideas once the average tank temp is 50deg. Assuming you can store water at 70deg on an immersion then an UVC will give you double the hot water of a TS. If you have a heat pump you will have to run it very hot for a TS which will destroy your COP unless you have a really giant tank. That said I really like the TS. It does a nice job of combining heating, oil boiler and solid fuel cooker and pressurised DHW. It could take an immersion and solar too if needed. Both are pointless for space heating though unless you can hold 2-3m³ of hot water. For your situation a direct UVC on a TOU tariff would be the cheapest long term. Have you thought about A2A HP for space heating. Ours is proving economical. I do my own servicing, (no G3 in Ireland). Takes 15 mins a year. Check the safety valves, clean the filter and top up the accumulator. It is dummy level if you have any mechanical competence at all. -
For plaster boarding I used to scribble the dimensions of the offcut in big numbers on it and stand it against the wall beside the pallet of fresh boards. Same with timbers. It was remarkable how often an offcut was almost perfect for an infill.

Nope, different beasts. A membrane is normally 1.5m wide, just a sheet of fancy reinforced plastic. A tape is only 50-200mm depending on application and has adhesive included. Along with your understated humility and bashfulness it's your best hidden quality.

Just reason back on Nicks suggestion. It's a good one. I just used a dilute solution of the airtight paint (soudal) as a primer. Going in with a neat first coat resulted in it not sticking very well unless everything was clean room decontaminationed.

Don't get too hung up on certified. Long term flexibility and dimensional stability is what you're after. Look for a product that doesn't shrink or harden over time.

That wide fit masonry tape is bungabunga party expensive. Cut a strip of normal airtight membrane, apply a bead of airtight sealant onto the ply floor and staple the membrane down over the top making sure the bead is continuous. Apply a thick bead to the wall then and press the membrane in place. A sausage tube will go a long way for £9.

Attic hatches should be limited in size to prevent anyone less agile and slim than a circus trapeze artist from entering. Amazingly Christmas decorations survive pretty well in a cupboard. Who would have thought it. If a single box kept out of the loft tips your house over the edge from austere bliss to hoarders bordello then you really have been living in the absolute limit. I would put the UVC into the utility room. Thermally vastly superior and central to all your taps. The only one that really matters by the way is the kitchen tap. Consider 10mm Hep to this if you can live with about 6l/min of hot water. You'll be rewarded by super speedy water delivery. Displacing something else out to the garage would be preferable in my view. Is there somehow preventing you having your ASHP right outside the utility? Absolutely minimising runs of piping outside the unheated envelope. Alternatively if there space you could put your UVC under the stairs.

Rigid PIR boards in cavity Walls. DON'T DO IT.
Iceverge replied to Iceverge's topic in Heat Insulation
At a guess I think this if for an external precast threshold. I'll keep an eye when I'm passing. It's a shame the boards are used. It's a generally well done site otherwise. -

I had a look at a new site recently. Good job was done on the blockwork I thought. The PIR Was installed in the usual fashion, far far from the worst I've seen mind you. Gaps between boards, wall ties not fitting correctly, mortar droppings on the boards etc. I maintain it cannot be accomplished to a satisfactory standard in real life and shouldn't be attempted. Bonded EPS beads or mineral wool batts are far superior.

Premixed concrete I assume is much the same as a 3:2:1 general mix which I make up for £85/m3 or 2400kg. Bagged premix concrete is about £6/40kg at best or over 4 times dearer. I bought my ballast in a truckload though so that may not be convenient for everyone.
