Straw bale ceiling insulation

We are also looking to use portal frames, and had looked at using fridge panel covered with coverbond steel, or a product like Corrolink from APS Versaclad- Website : www.apsversiclad..... We do not plan to have a hanging ceiling so were looking for a roofing material with insulation built in that would be attractive from the inside once in place. Not sure this helps you, but I will watch for your report as it will be of interest to us. Regards - Andrew and Mary

Excellent, I will use this on my work in Berdyansk.

I built a steel portal frame straw bale house with a loft and lined the ceiling with b-grade plywood and polyester insulation. What we did was to screw scrap 60mm top hat at right angles to the underside of the existing roof battens (also 60mm top hat). This gave approximately a 120mm space that we packed with polyester using bailer twine strung across to hold it in place before we screwed up the ply to the upsidedown battens. Before that, we packed with insulation and covered with ply the 250mm c-section that made up the portal rafters. The lot was finished off with coverstrips and varnished by roller with a water based clear finish (satin) that I also tinted with blue food colouring and used on the ply attic floor. Result- a somewhat timeconsuminmg but OK looking ceiling that is not too dark a looks good. It's been up for 6 yrs now and works well.

Would the Durra panels (the pressed strawpanels) be an option? They both look nice and insulate at the same time.
