Hi all I am buiding a 100 mm double block wall with 100mm cavity into which goes rigid 50mm insulation board.The architect specified Thermabate cavity closers around the windows my building supplies company has quoted for weatherbate. Will this do-------it all gets covered up anyway or has the BCO X-ray eyes.
BCO comes back BEFORE you plaster. I'd type both products into google and compare. Also check where the insulation should go at the windows, i think you close the cavity with it, using DPC as well, the kingspan website has diagrams.
