Windows have been painted foe hundreds of years. I always preferred to paint before glazing. They will need repainting one day 🙂

Trees grow a lot taller than 6.6m! Try a local sawmill

I doubt that they will be sharp enough to pick it up

I love those windows, have had nine for over ten years, no problems, fantastic quality. I can’t cope with plastic and have larch, the wood is fantastic.

The concrete subfloor is likely to be insubstantial and not very flat or level, it could be only 50mm thick too

70mm too thin, will crack. I like the idea of multiple layers of eps , you need a proper slab and for me that means min 100 thick concrete with anti cracking mesh and presumably ugh pipes in it too. Need perimeter insulation too pir? then min 4 months to fully dry out before laying wood on it

My plan would be to fill and seal all gaps, misses and cracks, remove skirting, check that the floor void is sealed wrt the loft, add additional sheet insulation over the entire wall areas, followed by plasterboard and skim

Spray outside with vinegar or dye in the water see if wet inside is acidic or coloured

In the old days brick arches were used , catnic lintels available for use in single skin span and load tables for concrete lintels wide openings with imposed loads need calcs anyway

I like notched in so joist sits on steel with noggins in between

The foil and foil tape is a vapour barrier, there is a question about how long it will last. how will you join it to the vapour barriers in the adjoining elements? Wall under the floor, wall, window, access hatch linings etc? then where is the air tightness layer? Is this hermetically sealed to adjoining elements? I always used a sheet of thin poly, omit the tape and join the poly to adjoining elements

Better, a lot better in air leakage terms and bridging and cost not to have them insulation fixings are good - fixing foam then mechanical fixings for me

Perfect place for a sculpture

There are hundreds of thousands of loft conversions where this has not been done and we don’t hear of problems, why waste the effort

I used quite a lot of metal corrugated tiles that. Old go down to 7.5 degree pitch looked like concrete pan tiles
