Our draught seals are machined into the timber components to become an integral, practically invisible part of the window. Our Draught Seal & Restore Service is ideal for conservation areas and listed buildings.

We have been using the same top quality British made draught seals for over 20 years.  Brush draught seals are the best option for long life in a sliding sash window.

Sealing draughts in your home will return significant savings in heating and cooling costs, as up to 25% of heat is lost via air leakage in a typical home.

Period french windows and doors are not regarded as being very energy efficient.  The frames have inherent gaps that allow the doors to swing open and the timber frames can also warp over time, creating larger gaps where air leakage and air infiltration originate.  

Draught-stripping your existing period doors and french windows can reduce the draughts from them by almost 90%, therefore significantly reducing the air cooling or heating requirement needed for the room.  Warm or cold draughts make air cooling and heating systems work harder and make occupants feel uncomfortable, often adjusting room thermostats to compensate.  

"Draught-proofing is one of the most cost effective and least intrusive ways of improving the comfort of occupants and reducing energy used for heating with little or no change to a building’s appearance." Historic England
