Fixed the draught-proofing on the openers/vents on 3 of our 5 Velux roof windows. The original 2" wide foam strips stuck on the underside of the wooden openers had perished over the years and took a bit of effort to remove but I managed to replace it with some foil backed thermal insulation and draught excluder to seal and gaps. Made a nice neat job of it even if I say so myself.
