Less than a quarter of the heat lost through a typical traditional window escapes by conduction through the glass.  The rest is air leakage as draughts.

All of our more advanced window solutions include this service as their foundations. 

Sash Weather & Draft Seals.

Sash Seal benefits include:

  • Primarily they seal the gaps where draughts enter, thereby improving the comfort & energy efficiency of your home & saving you money on energy bills.
  • Low friction draught seals enable free movement of the sash, yet are tight enough to eliminate intrusive rattles.
  • Air borne noise, dust and other pollutants that are suspended within draughts are also greatly reduced.

“ …one of the best and least intrusive ways of achieving improved performance from windows in old buildings. This will considerably reduce heating bills and energy use… reduce noise and dust ingress… Most importantly, draught proofing does not damage the visual aesthetics of an old building.”

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.

Traditional double-hung sash windows are not regarded as being very energy efficient.  The sliding sash window frames have inherent gaps that allow the sashes to slide and the timber frames can also warp over time, creating larger gaps where air leakage and air infiltration will occur.  

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

Whilst heat does pass through the glass itself, less than a quarter of the heat transfer through a typical sash window is by conduction, the rest is by air infiltration - draughts.   Heavy curtains or close-fitting roller blinds can help cut the amount of heat transfer through glass by more than 30%. 

"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

 

We understand the charm of traditional wooden windows and all of our work is designed to be as authentic as possible.

Heritage aproved draught seals

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.

Windows are a favourite entry point for burglars

Various catches effectively bring the sashes into a locked position, however the screws holding these in place are small and these catches should not be considered an effective security measure. We have a range of sash window security options available.  We also supply a wide range of sash window furniture, available in variety of finishes.
