Front Door

I built my own door, oak frame 32 x 95 round solid fire door blank with two sheets of pir, inside 10mm and outside 25mm, clad inside with oak faced 9mm MDF rebated into frame, outside with left over engineered oak flooring onto the frame, in a door frame with good draught seals

Air sealing windows and doors

  1. Ensure that all the cavity insulation is in place
  2. Fit cavity closer insulation to mitigate thermal bridging
  3. Seal the edges of the insulation and fit the next layer immediately behind the cavity lining.
  4. I used painters caulk to stop air ingress between the frame and the lining board.
  5. Seal any internal corners
  6. Finally fit the lining material, in my case plasterboard
  7. seal to frame with a neat bead of acrylic sealant, here brown is best and on wet plastering a hermetic seal is made between the plasterboard and the blockwork.
