Not even sure I understand 😂 Could you put a plastic pipe in the cored hole, plaster up to & around, then fill the plastic pipe with expanding foam?

Don’t suppose you have the core that was drilled? Could glue it back in place. You could fill the hole with stone & mortar.

What is on the drawings? I would of expected pir infill of the rsj before the osb.

Soudal Silirub 2 in neutral is what I use for sealing around exterior, windows etc.

I used BPC for my last house, Vent Axia. Used CVC for the new build, Brink.

It does exist, I have one

I wonder if would turn? Possibly anticlockwise?

Pretty sure it will just prize off, small bit of plastic (credit card) to lever off gently.

Is that an Internorm door? if you look at the end of the door, there will be lots of screws holding the gear/mechanism. Be worth taking it out but the handle will need to come off first & pull the spindle out.

Overthinking it 😉 I used tiling battery to create the air gap but it also allows you to stick the insulation to the batten with silicone, make sure your insulation is good tight fit between the rafters, use airtight foam on the wall plate etc.

Cut the bottom of the sheet of insulation at 45 degrees so it sits on the wall plate, (eaves end) marked on your photo.

I used off cuts of tiling batten to create the air gap, 45 the bottom of the insulation so it sits on the wall head.

Is that water on the bricks above the slab? Marked on the photo.

Makita 😉

Just wash the heat exchanger in the bath, I’m sure I read somewhere that it has to be fully dry before it’s fitted though? I had to pack my vent axia unit out a touch at the bottom as I had water coming out of the front but only slightly, this helped the issue. I was shocked at how much water the unit produced in the winter as I was catching it in a bucket until I got the drain sorted. Mine was in a cold attic & insulated as good as I could get it.

I bought my own anemometer & balanced it, I followed a guide on here.

Welcome to the forum. Sounds like you have researched it well, it’s easy enough to self install. You will need to insulate the unit, ducts & manifolds in the attic. I can’t help with the calculations but others certainly will.

I have just ordered the Tricel Novo 10 gravity outlet. It won’t be operational until next year. Looks to be a good treatment plant.

Good luck with the test, what are you hoping to achieve?

Show off 😐 Prize will surely be the snagging list from the mrs 😬

Welcome to the forum, look forward to seeing the photos as you progress 👍🏻

Welcome to the forum, there will be a lot of knowledge on here for you 👍🏻

Ecology. No issue if you own the land. 6-8 weeks for application, quite difficult to get the first appointment. You need to have a plan of costs, proof of income, outgoings etc. Very helpful & easy to deal with.

Welcome to the forum. We started our timber frame in August 22 & still have a long way to go yet.

Welcome to the forum, look forward to seeing your drawings.
