Where you to, may be easier to call around.

Yes. But nothing to stop a second layer going over the top. That is one of the beauties of GRP, you can hack it about and then stick more on.

Easy, make up a fall from PIR, then lay up with GRP.

Homes given poor energy ratings on the basis of faulty modelling...
SteamyTea replied to MAB's topic in Heat Insulation
What is a bit silly is that the energy suppliers know the actual usage, and they can share that data. That takes a lot of the guess work out of it all. -

SteamyTea replied to MAB's topic in Heat Insulation
Would have to look at the underlying data and assumptions. Do people in old draughty houses have colder houses? If the assumption is that all houses have a mean internal temperature of 20⁰C, but F and G are in the real world 18⁰C. Then the assumption is right, but the data may be misleading. -
Why not have a go yourself.

I think you can get automatic versions of those, @Nickfromwales fitted one if I remember rightly.

That does beg the question as to how much power do you want this, basically off grid system, to be able to deliver. Think you would need some sort of safely cut off to totally isolate the house when there is a power cut, and I think that regular inverters use the grid impedance for that, not the voltage and frequency, they are second line of defence.

Some design strategies please
SteamyTea replied to Nic's topic in Energy Efficient & Sustainable Design Concepts
Almost. It is the stiffness. As 'sound' is really just a mass of air moving, it has kinetic energy. If it hits something that can easily bend, then some of that kinetic energy is absorbed, and ultimately converted to thermal energy, which is then radiated back out at a different frequency. You can, with a very stiff material, set up a room that would, for a fixed sound source and frequency, in such a manner that the reflected sound will interfere with the source and cancel itself out. The room will heat up though. One of the reasons that foams absorb sound so well is that they have unevenly sized and spaced voids in them, this sets up interference at the micro level. Some neoprenes, like wet suit material, can be very effective for very little added thickness. The other main reasons is that they are flexible, this allows the voids to change shape and size when compressed, absorbing a greater range of frequencies. -
Ah, 'imprinting' how the racist in society control females in their own societies. Such an unfortunate term. Sorry, very off topic, just the way my wind works sometimes.

No. They trade in low carbon generation, not the same thing at all. Buying 1 MWh of low carbon generation, to be used sometime in the future, does not stop 1 MWh being generated elsewhere right now. Nor do I, but as I am on E7 I am having one fitted next month, if they turn up. As part of the EDF questioning and consent, if you are over 60 years old, they ask if you can be put on the preferential/vulnerable person register.

I don't think the images are doing it justice. Or is it like 'Spot the Ball'

Understanding bookcases: how shallow and tall can they be?
SteamyTea replied to Garald's topic in General Joinery
There is the UK and then there is Cornwall. It is closer to France (192km) than London (411 km). I am told that there is an Ikea in Exeter (159 km) but as that is in Devon, one never stops if the flag of St. Piran is showing. -

They make better stuff than Billy Bookshelves, god I wish were were still part of the EU. -

I never looked at the price. Wonder what is in it, unicorn wee.

Well they understand their market.

I think how it works us unevenly, and that is the main problem. Why economist use purchasing power parity. It evens out a lot of the difference. Basically we should stop thinking about the price, think instead of the time taken. Money earned is only time multiplied by talent.
-
I think that is probably the nub of it. Big difference between making EVs and guns, even if the do the same amount of societal damage. Is that really important in a global economy? I don't use my nearest corner shop as it is expensive and has limited stock, I go to the national chain an extra 100m away. Again, does that matter in a global economy. I am sure we could swap huge amounts of the economy to more productive methods, especially in agriculture, while reducing costs (cash and environmental), which will reduce inflation and interest rates.
-
Yes, especially with so many fixed rate loans. How necessary is growth in an economy. If you say change the building of a £20bn nuclear power station to £20bn to build wind and solar installation that produce the same amount of energy, the economy in that sector stays the same i.e. no growth. How does the cheaper power that Wind and Solar produce affect inflation, downwards I would hope.
