Crofter

Interesting. Our MDF has stood up pretty well. Eight years so far as a busy holiday let occupied about 200 nights a year. We don't go mad with the floor mopping though, because the floor is bamboo. And in the bathroom, I have replaced one small section of MDF with tile because it was suffering from damp.

I wanted solid oak. Then I priced it up (not just skirtings- architraves, liners, and stops too) and had a change of heart. Considered veneered, but it wasn't all that much cheaper and seemed far more vulnerable. In the end I just went with MDF, and painted it. Very happy. Not only did I save a lot of money, but fitting was an absolute doddle. If you make a mistake, you just cover it with filler, sand it smooth, and paint. Can't do that with solid wood! I already had bamboo flooring, exposed timber beams, and plain white walls. The colour of the skirts was a nice extra touch to what could have been quite a bland interior.

Oh well in the end I've chosen Illbruck me315, because the places selling the other stuff all wanted silly money for delivery (of a single roll of tape) to a Highlands postcode. Hopefully it'll be up to the job.

Is Vana the same as Pro Clima?

I've just started replacing a couple of windows. Previously I'd used SIga Wigluv black tape, and I can confirm that after nearly ten years it's still perfectly adhered and has done its job perfectly. It's flippin expensive though. I can get e.g. Illbruck ME315 for a third of the price, and it also seems very highly regarded. I'd be interested to hear what tapes other people have used and how you would rate them.

That must depend on the product. I've got a set of French doors from them and they're definitely not completely airtight. They were cheap though, and they're on a pretty exposed elevation.

I'd be surprised if you could get 2G to outperform 3G without it ending up costing more. When I was recently shopping for new windows, I was offered a Krypton option and it pushed up the price much more than simply going to 3G.

I don't know about the English rules but AFAIK they should just specify a u value. Good 2G can be better than poor 3G. Not necessarily cheaper, though.

Ok that's much better. If your walls are already at 0.18 then improving the glazing will see a more substantial return because they are now the weak point, by far. People don't always realise that even the best windows money can buy will lose three times as much heat as a BRegs minimum wall. And cheap 2G will be up to uW 2.0 which is appalling. Everybody will find their own happy place on the cost/benefit curve, but personally I wouldn't ever aim for less than 1.4 as you should be able to find that for about the same price as the 1.6/1.8/2.0 crap. 1.1 is widely available at sensible prices. In my experience the prices only tend to rise markedly once you go below that.

1.8 is horrendous for a wall (you don't mean 0.18 do you?) but improving your existing walls is much harder than retrofitting better windows. None of this is rocket science. It comes down to surface area and u value.

They were imported from Poland. I got mine via a small outfit in Kirkcaldy, but @craigcan supply them too.

Same here. We've spent four out of the last five years living at anchor, using solar/lithium for cooking, and rainwater collection to supplement dock water. Hopefully we can get our recalcitrant watermaker running this year, we have plenty of power for it. We still have gas for cooking but it's strictly a backup option. Likewise, we can in theory charge the batteries from the engine, but the solar can put out six times as much power so we don't bother unless we're using the engine anyway. What makes this viable is that the boat isn't in the UK. Remove space and water heating from the equation and everything becomes much easier!

We've just taken delivery of a Neo sliding door. It was absolutely unbeatable for u value (0.74 uW) and was considerably cheaper than any aluclad iron. Haven't installed it yet but the quality looks good. Mine are dark grey on the outside, and as far as I can tell this is a solid colour rather than a foil wrap. I also took the option of having the glazing units delivered separately, which has made handling much easier. It will also allow me to install the frames by screwing straight through the frame. The glazed units were delivered in robust transport frames, unlike the cheaper units I bought from Modern UPVC Glazing. All in all, I'm quite impressed so far.

Floor: 300mm mineral wool Walls: 150mm wool+ 50mm PIR Warm pitched roof: 150mm wool+ 100mm PIR Plus airtight membrane battened and taped. Windows are 3G with u values of 1.0 or less.

Due to damage I've had to replace a couple of aluclad units, and have decided to go uPVC this time. I was able to improve from 0.98 to 0.74.

I think as you approach very low u values it's better to switch your attention to better airtightness detailing, because that's going to be where the bulk of your heat loss occurs. But it's not just about saving money. You're creating a comfortable house without damp, drafts, condensation, and mould. And it's extremely hard to improve insulation and airtightness later.

So just to conclude this, I finally made a decision. Went with the DHP490 drill and DTD153 impact, both a decent upgrade from the base models. Plus the 186 recip saw. Only added a single 3Ah battery, because once my tools are all reunited I'll have plenty of batteries. Powertoolmate won out in overall cost, there were only a few quid in it. If I'd wanted to, I could have split the order between two or three different places to get the absolute lowest prices, but I'd have lost out any savings in additional delivery charges. Looking forward to my new toys

I believe so, but it would get pretty frustrating waiting on them.

It's possible you ended up with the 'SD' charger, which looks similar, but has no fan.

This is the one I'm looking at, same as I already have. Definitely has a fan. https://cnspowertools.co.uk/makita-dc18rc-18v-lxt-li-ion-charger.html

Yup. I can get the Makita fast charger for as little as £14 if I shop around. The double charger is nearly £100!

Ok just about to click the button, but before I do, does anybody have a discount code they could share?

I would start by looking at all the background heat you expect to be generating in there- two humans, a fridge, some cooking. Then do a basic heat loss calculation based on notional insulation values and the surface area of the hut. This will be dependent on outside temperature- do you want to use this all year round, or summer only? Just to give you a data point, my little place needs no heating for about nine months of the year. The fridge, hot water tank, and a bit of solar gain seem to be enough. I've got u values of between 0.1 and 0.15, with the windows at about 1.0.

I've been using a corded electric chainsaw for my log pile, and I *thought* I was keeping the chain sharp enough. Recently switched to a brand new chain and what a difference... knife through butter. It only cost about £8 as well. Worth every penny!

Fair enough. I wish I had a note of what my first pair were, as they were perfectly good.
