Best 'Thin' dry lining insulation

unregd147

We are retrofitting underfloor heating and extending the house.

Due to spacing constraints in the existing building I can't lump thick insulation onto the external walls in the kitchen area.

I have found a kingspan product OPTIM-R that suggest a 20mm board is comparable to a 60+mm board of a standard type. Anyone have experience?

What should I be looking for here?
Any other product suggestions. Ideally looking best for insulation <50mm thick.

I don't think optim r can be cut , it needs to be measured bespoke for each project as it's a vacuum panel

Maybe someone else on here can confirm

Aerogel ?

Have you considered external wall insulation?

either custom sized or you build to suit their sizes.

I remember being in the same situation about twenty years ago and I used a board with black or dark grey insulation on the back of it. It had higher than normal insulation level and cost a fair bit more than the standard insulation board but for the life of me I can't think of the name of it.

Ha, ha, Platinum!

The thinner the insulation the more expensive. Aerogel and other vacuum insulation is very expensive. If it's only the kitchen it might be affordable but I'd look at external insulation of possible which has a grant available.

Just thinking about it though how can you hang cupboards etc off of it, you will puncture the vacum panel with the long screws surely

Aerogel is not a vacuum insulated panel.
