As this is temporary, could you not cut some plywood up that is deeper than the current beams/joists/rafter (not really sure of the correct terminology) and sister then up to the existing beams/joists/rafter. With correct trimming at the ends, they could bear onto the top of the wall. They could be cut to make the beams/joists/rafter either deeper or taller. Something like this. Or better still, if you are boarding, the other way around, so the original timbers are at the top.

@Gus Potter @SimonD I use Libreoffice Portable https://portableapps.com/apps/office/libreoffice_portable Can take it anywhere with me. The problem may be that I used REGEX() to split up the array's columns and rows headings, not sure if Excel supports REGEX() (it should as it is a normal function in the IT world). I did think of one problem and that is when using MVHR, the result should be added to the ACH result as it is, in effect, and extra 'leak'. This part was not a great deal of work. I may try and make one that separates the 'ground' face of the cuboid and adds in some percentage of window area.

@Gus Potter Seem to remember that JohnMo had a similar problem, must be Scotch Software. This, it is saved as an .xlsx file. Compare U-Values and ACH.xlsx

Been a bit bored as I have not been able to concentrate on anything much recently, but life is getting back to normal. I read on here a lot about the advantages of insulation, airtightness, MVHR etc, but this misses a few points. Form is one of them, a simple cube is a pretty good shape for thermal efficiency, and the bigger it is, the better it looks. So I thought I would knock up a very basic spreadsheet that can be used to explore the differences between size, form, thermal properties (just U-Value), air changes an hour for a cuboid. This is basically to just show the ratios and theoretical power transfers. Cells B3 to B11 can be changed with the snapshot results shown in cells B13 to B17. Below that are some data arrays that show ventilation and fabric losses, and ratios for surface area to volume and fabric to ventillation for different form factors for the cuboids. Not sure how useful this will be to anyone, but it does put numbers to changes i.e. you can change the ACH and U-Value and see which will have the greater effect. This is a very limited scope spreadsheet, so a lot of interpretation is needed. It does produce some charts though. Compare U-Values and ACH.ods

And very relaxed you will be as well if you put it next to the Bob Marley tree. Personally I just want some of this.

Try putting a cheap phone up as high as possible and see what happens. Or you could play about with an old satellite dish and see if you can get a stronger signal. When I was at the college, I managed to get onto the university network that way, and I was about a third of a mile away.

Replace with for for.

Or a U-Value of 0.35 W.m-2.K-1. U = 1 /R. Half the BR's wall regulations. Mineral/Rock wools, at 135mm thickness is 0.3 W.m-2.K-1 (at a k-value of 0.04 W.m-1.K-1. So not really sure what to make of that claim, other than they have somehow factored in ventillation losses.

There is a 5G mast 200 metres from my house. I must go down to Goonhilly and Poldhu, the spiritual home of radio, and see if there is still no signal.

Never tried one, but two things. Are the legal, seem to remember than some are not. Do they do a 5G version, 4G is to 2010s.

The new member was @jon-lee, but not posted in a while, think he was scared off by a mod. Shame.

Concrete is a fascinating subject. We had a new member joining a few months back that was involved in it, can't remember who now, think he was from the South East.

A legend in a loincloth.

Was an Alan Davis program about what would happen if all the rats vanished. Our lives would be worse. https://www.bbc.co.uk/sounds/play/m002rf05 Now this is how I deal with fat and waste. First we collect the food. Any fat, liquid or solid is kept here. Locked away for insurance purposes. This machine does a bad job of getting the crud off. With all the waste water going down this hole to the grease trap. It has been a slow day today so I have been hiding from workmates. They think I am writing a report about the drains.

Why would it if they were the same energy storage and similar power delivery. Workmate of mine did the same. Found out the problem is the way she used them i.e. turns the fan in when she gets home and leaves it on.

Learn from the Master.

No you didn't. It is kWh, the measure of energy, storage in this case, kW is the power. Good price though.

This heat pump installation is going to cost a fortune to run. The CoP is going to be just a little over 1 I suspect. All quite unnecessary as it is down to how it is being operated (or inappropriately operated). Trouble is, all the things that Zoot is saying, is just a repeat conversation from 3 years ago. Repeating the same mistake while expecting different results is commonly known as the definition of insanity.

I thought it worked by buoyancy, so hot are at the top, which will be lower density, will stay at the top. Probably find that any hot air that is drawn downwards is caused by a venturi effect caused by a through draft at low levels i.e. leaving windows and doors open. I think you are correct here, people get very hungry up on CO2 numbers but I think there are more problems, both physical and emotional, caused by high RH. There is a good correlation between RH and CO2 in occupied buildings anyway, unoccupied is a different story.

Over 70 years. It still needs to be used correctly, I used so out of date powder and it failed to adhere, which was a bit of a surprise.

Maybe @Gus Potter can answer this better, but I once saw a Youtube about the wire rope used in suspension bridges. By using multipole strands of relatively small wires a number of properties could be designed in, tensile strength, flexibility, safer failures, easier manufacture etc. I feel the same way about multiple smaller fixing. One may fail, but the others should still be able to cope (why a safety factor is used). They are also easier to fit correctly (I worry about people using adhesives without a proper understanding of the limitations).

Must be those cloven hooves for fingers of yours. I have a very gentle touch.

Is your finger sore from tracing the words and your lips still moving. Will this latest LLM make you a better girlfriend that will indulge all your pervy fantasies.

Are you still running like a normal heating system i.e. turning it off at night and when you are out.
