Roof Ventilators When installing Warmcel, which is a loose insulation, it is important that you do not block the roof eaves. We now sell 280mm wide PVC Roof Ventilators which can be cut to size with scissors and put in place between the roof timbers. No fixing required. If gaps between timbers are 400mm wide, allow 11/2 ventilators per gap. Cost: Up to 20 £1.20 each, 21 to 50 £1.10 each, 60 plus £1.00 each. All prices include post and packing.

Fire/Acoustic Recessed Light Covers If you have any recessed lights in your loft area, then they need to be protected from any insulation. We sell 60 minute fire-rated and acoustic-rated lightweight, flexible light covers that are ventilated to prevent heat build-up. No additional supports are required and they can be used in suspended and plasterboard ceilings. Insulation can be fitted around the light covers but not over the top. Sizes: 150mm outside diameter x 150mm high (for 150mm thick insulation around the cover) £12 each 250mm outside diameter x 250mm high (for 250mm thick insulation) £20 each
