Central and Eastern Europe using this technology for long decades. Glad to finally see it in the slow adopting UK. When you feel cold you put on a jacket don't you? House should too.

Thank you for the video. Getting ready to do external wall insulation on my house . I had a couple questions, but you cleared them up for me.

Cold bridging around the external window reveals and potentially between the joins of the insulation. Ideally the joins should be sealed or foamed to help prevent this happening.

Overall a well presented video, but how is the plinth dealt with below the bottom bead?

[mihir]

Wow! Very impressive! Do you know how one can install these insulation pads (90mm) on a curved wall?

[owaisaziz]

Excellent Video. This was a demonstration for a Single House. Can this same solution be scaled and applied to 10 Storey Concrete walled buildings???

How do you finish on a gable end apex roof, tiles finish flush with roof

[ttag]

Good product, you’ve missed how to install oversills tho, I’d like to see it in details ie take out existing one if there is and fit new oversills plz

[leethornton]

After the Grenfell Tower disaster some insurance companies are requesting any external cladding system used must be made from a fire resistant material. Polystyrene insulation while different from what was installed at Grenfell, is being seen as a potential fire spread risk. Small numbers of mortgage lenders are now insisting this is removed from any building before agreeing to any sale. The insurance industry sees any suspect cladding material as too risky and will refuse cover.

Is this breathable for use in older solid walls then need to breathe? How do you deal with none 90 degree corners like bay windows etc?

[wesleytaylor-rendal]

Can i apply the primer onto painted concrete/clay bricks. Can i apply onto wood?

I got old house where a wooden beam sits ontop of walls throughout house. Then the roof sits ontop of that? Would i get any thermal gain by adding it onto the wooden beam? The beam seems to be thick enough to keep nice thermal delta.

Great video, but it misses out all the hard bits, like guttering, soffits boiler vents and electric/gas boxes
