Draught proofing - The facts.
You may be surprised, but the total airspace around the average sash window is equivalent to a hole in the wall 6 square inches in size. That’s big enough to fit your arm through. Probably big enough to crawl through if you added them all together! With all this room for manoeuvre, it is no wonder that sash windows have a tendency to rattle and allow for draughts. Draught proofing sash windows can solve all of this easily.
It is also commonplace to position a radiator directly beneath, resulting in energy and money going literally straight out the window. Not only this but, where valuable heat escapes, undesirables can make their way into your home as well.
How will draught proofing my sash windows help?
Airspace is inherent to the design of sash windows; it is necessary to allow the window to move. The Envirosash Draught Proofing System will simply fill this gap with a soft brush, creating a barrier to all of those unwanted nasties and keeping valuable heat in. Your home will instantly become a cosier, cleaner, safer environment, not to mention cheaper and greener to run.
Will it be visible?
No. Using the Envirosash Draught Proofing System, the brush strips, known as a weather fin piles, are fitted between the inner and outer frames, sealing the gap. They will literally become part of the frame. This cannot be seen unless you get very close and have the window open.
How will it affect the movement of the sash windows?
It will improve it.
During the installation process we completely remove, rehang and rebalance each sash window. They will slide easily and won’t rattle. Where necessary, the frames themselves will be expertly restored by our experienced team, ready for draught proofing. Consider it a full service!
Will this require planning permission?
You won’t need planning permission for this; draught proofing sash windows are fully approved by English Heritage and conservation officers. In fact, thanks to a government green initiative, only 5% VAT is charged for this service. It is also strongly advised by the Energy Saving Trust.
In order to minimise heat loss and maximise noise insulation, it is highly recommended that draught proofing is combined with our slim double glazing service. In some cases this will require planning permission – you will need to contact your local conservation officer to find out. Read more here.
