Extension Insulation

[Maddog]

I am planning an extension and want to know what insulation to use

The construction will be 100mm cavity wall with 60mm Kingspan insulation

Should I go for insulated plasterboard on the inside?

What is the minimum thickness I can use and what are the best brands as I don't want to fill house with insulation?

Are there problems with this type of insulation in future?

Will treble glazing be much of an advantage over double glazing?

thanks

You should consider external insulation IMO.

Its benefits are well-covered on the Construct Ireland Website.

I think Durkan EcoFix offer a free assesment and estimate, but there are others.
