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.

Bespoke period sash windows can reduce the draughts 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.  

Wood is a natural insulator

The natural insulating properties of timber make this an extremely energy efficient building material.  Timber window frames are highly energy efficient as they do not conduct heat. 

Timber windows help to lower your carbon foot print. 

Wood is a sustainable building material, derived from a renewable source. Any home owner choosing green living should consider preserving or reinstating timber windows.    

How Does low-emissivity glass work?

low e glass for period casement and sash windows

Low-e glass has a special coating which is a poor radiator of heat and does not allow heat to be transferred through the glass. In winter, heating is reflected back indoors; in summer heat from the
sun is reflected away, keeping the room cooler
