The Great Thermal Mass Myth................
Gone West replied to Jeremy Harris's topic in Boffin's Corner
If you had a vented cavity behind your outer skin how would that affect the temperature of the main wall construction and hence decrement delay.- 122 replies

The Great Thermal Mass Myth................
Gone West replied to Jeremy Harris's topic in Boffin's Corner
Yes, that's what I was thinking in respect of how much solar gain could be stored in the floor slab. I was thinking it would be very difficult to work out unless it is a more or less a homogeneous material. I have a concrete slab with a layer of tile adhesive then porcelain tiles. Presumably how reflective the surface of tiles is would also affect the result. Some of the flexible tile adhesives have air bubbles as well, so would act as an insulator. It would be interesting to know how much is being stored in the floor when the sun shines on it but I guess not really possible to work out, although maybe possible to measure.- 122 replies

Is there any data showing what the thermal gradient is or whether it is linear in different materials with differing thermal conductivity and capacity.- 122 replies

Changing electricity supplier
Gone West replied to Crofter's topic in General Self Build & DIY Discussion
Yes, I remember scratching a hole in the ice on the inside of my bedroom window so I could see out. IIRC our only heating was in the living room in the form of a paraffin heater. -
Welcome to the forum Nick. It looks like you're making good progress. Good luck with the rest of the project.

I found that to be the case and went back to a sprung mattress and it's fine now. -
Changing electricity supplier
Gone West replied to Crofter's topic in General Self Build & DIY Discussion
I'm well into OAP territory and can remember the ice inside and am thankful things have moved on, and I can sleep in a bedroom at 22C without having to worry about draughts or the electricity bill. -
As Ed said there was no excavation required by UKPN. I took the ducting up to the base of the pole and they connected at the top of the pole.

Our electricity connection was £636. We laid the ducting, with a couple of hockey sticks, from the pole in the orchard, at the corner of the garden, to the meter cupboard which was 17m. We fitted a draw cord. For the £636 they supplied the cable, pulled it through the duct, and connected both ends.

Changing the name of your house
Gone West replied to DreamHouseDreamer's topic in Introduce Yourself
Friends of ours tried to do that and it took them ages to get it finally sorted out. From their experience, which was near Deal in Kent, I would change the existing house name first, well before starting the new build. I would then give the new house the old name. -
Passive Haus on a budget?
Gone West replied to bobberjob's topic in Energy Efficient & Sustainable Design Concepts
The worst thing about current building regs. is the airtightness requirement. If you aim for a maximum of 1 ACH the rest of the regs. aren't too bad. If you can improve on the insulation levels so much the better. -
It was replaced at no cost to us. We had several smaller panes replaced, also at their cost, where the marks were obvious.
-
We have a 3/4 glazed gable that is 4.1m high made up of three vertical triple glazed panes. We had marks on all three of the panes and we had the two largest of the panes replaced. We still have a small mark on the smallest pane but accepted it as it is virtually impossible to notice.

It's standard practice for the farmers around here. They do what they want and if there are any complaints they put in for retrospective PP and then ignore any subsequent conditions.

I doubt he has reached outside his own expertise. Netting doesn't work very well.The farmers around here net the cherry orchards but there are always birds inside the netting from blackbird size downwards. All that happens is that when people appear the birds panic and get caught in the netting and usually die.

MVHR - I think we’ve cracked it!
Gone West replied to lizzie's topic in Mechanical Ventilation with Heat Recovery (MVHR)
@lizzie I'm so glad you've got it sorted and are now comfortable in the house. Hope you are as successful with the UFH. -
Welcome to the forum and good luck with future projects.

Are there alternatives in your area to having an Openreach line. I got totally pissed off with Openreach after months and months of arguing and them not doing what I wanted so I used a WiMax company. They installed everything within a few days, faster broadband and a landline number using VoIP and cheaper than BT.

Welcome to the forum Simon. Plenty of ICF self builders on here to quiz. Good luck with the project.

I-Beam/I-Joist First Floor hanging Air tightness
Gone West replied to Patrick's topic in Timber Frame
There are different types of spray foam. I can only really comment on Icynene which although we had to do a lot of trimming, worked well for us. It is sprayed on very thinly and expands IIRC about 100 times so layers of around 100mm are built up. It sets into a rubbery flexible foam that off-gases quickly and after a couple of days there was no smell. The only disadvantage I have heard about is that it doesn't stick very well to a cold surface so it's not a job for a cold winter. Icynene BBA.pdf Icynene Spec.pdf -
I-Beam/I-Joist First Floor hanging Air tightness
Gone West replied to Patrick's topic in Timber Frame
If you attach a wide strip of membrane to the I-beams behind the ledger plate before fitting the ledger plate you can tape the membrane to that strip on the first floor and on the ground floor. -
I-Beam/I-Joist First Floor hanging Air tightness
Gone West replied to Patrick's topic in Timber Frame
Our first floor metal web joists hang from a ledger plate that is attached to the I-beam wall studs. We used 300mm I-beams and extended them to 350mm by adding battens to the inner flanges of the i-beams. The ledger plate is the same thickness as the battens and sits on those battens and is nailed to the I-beam flanges. We don't have any membranes or tapes in our construction as the wall itself with the Icynene insulation is the airtightness layer. We achieved an airtightness result of 0.47ACH. -
