We can't rest on our laurels though we need an industrial strategy that aligns with exactly the products and systems you describe.

Welcome to THE forum for people like us - we are building in Kent!

Has anybody got any experience with FAXMAX battery power tools, Drill, Impact driver and angle grinder. My nephew is thinking of investing and he quite likes the look of them?

Yes - we did a hydro test to 1200psi, the steam generator is not my build I am just doing the controls which is proving to be a big pain.

Yeh - me too, and I build steam locomotives - don't know why, although I am currently working on a flash steam plant for a car - right pain, so I guess I will have to get back into thermo to get it working reliably - how much energy have I got in 3 litres of steam at 600PSI contained in 20m of steel tube at an average of 400degC I wonder.

Yes - were within 5% of the official test a few days later.

We did the same but I used a variable speed dust extraction unit and even on the slowest speed I had to restrict the hole so much to get it to hold the pressure.

That's is an awful lot of pressure. 1.5psi = 6000 Pa = 120 x the passive house test pressure = massive load on a door (3000lb @ 72inch x 33inch x 1.5lb)

Because you have to fill all the voids. If you have flat timber frames it is easy but then you have massive cold bridges on the outside. We have I joists so the void is odd shaped - don't know what you are considering. Filling cavities is easy, just drop the batts in as you go.

The fitting won't be easy, we had it as an option but chose the blown cellulose in the end. Although there are some places we used it because the space was too small for blowing.

I think there are quite a few in that range. Mineral wool: 0.030–0.040 W/m²K Expanded polystyrene: 0.030–0.038 W/m²K Extruded polystyrene: 0.028–0.038 W/m²K Polyisocyanurate (PIR) and polyurethane (PUR) foam: 0.022–0.028 W/m²K Cellulose fiber: 0.04–0.05 W/m²K

We just used it where we needed the load bearing capacity, everywhere else we used PU or EPS100 if we could not get the right PU section. Cutting compacfoam is hard. They say you cannot cut it with a circular saw - I say you can't! I did find my hot wire did it on full power going slowley.

We used a structural polystyrene from Green Building Store. Compacfoam

we got luck there - no trees anywhere near us!

I did a training course 2 days at BRE was good and more interesting to watch the teams from the developers getting to grips with it. That was back 2018. It is time heavy to use but as I have built I have been keeping it up to date and initial work is showing that it broadly alines with the facts even though we have, so far, not put any heat in it.
