Insulating Walls Of Converted Attic Crawl Space

    I'm currently re insulating an attic crawl space. I've used Moy Metac between the joists and I've laid Xtratherm rigid board insulation and chipboard over it.

    I'm not sure what to do with the plasterboard walls. I know that the Metac is designed to retain rising heat (in a ceiling, etc.). Is it ok to use it vertically on the side walls also or should I just use rigid board insulation instead?

    yes its fine, but how will you support it and have you thought about air-tightness? + don't forget to leave ventilation from the eaves into the crawl space and on up to the ridge..

    Thanks again, Bryan. I hope to support it with something like chicken wire. And I'll make sure that it's not compressed.

    I've left an air gap by the eaves. What should I be doing about air tightness?
