Exposed wooden floors look beautiful in period homes but they can be draughty, leading to 15% heat loss. Mitchell & Dickinson has solutions that preserve the beauty of your floorboards but cuts out those nasty draughts.

Our underfloor insulation uses sustainable, all-natural sheep’s wool. It is fitted in the space under your floorboards and held in place with a robust mesh. The boards can then also be expertly filled using coloured-matched marine deck caulking to seamlessly close draughty gaps. And like underfloor heating, because you are physically closer to your floor than you are to your ceiling, those draughts aren’t whistling up and around your home. You really do feel the difference when a floor is insulated.

Benefits of sheep’s wool under floor insulation

Mitchell & Dickinson’s eco-friendly sheep’s wool underfloor insulation is treated with natural borax to prevent damage from pests. It won’t irritate your skin or respiratory systems. It also supports British sheep farmers – improving economic resilience – and uses little energy in manufacturing. Sheep’s wool insulation is also biodegradable, reducing its environmental impact at the end of its lifecycle.

Marine deck caulking

Just as it sounds, this solution is taken directly from the marine industry. Open floorboards where there is a void beneath, are often draughty making your period room feel colder than it needs to. We use a specialist marine caulk to fill the gaps in your floorboards just like they do on boats, to stop the draughts without impacting the beauty of your original wooden floor.
