New wooden sash windows - fully draught proofedCorporate Members of The Guild of Master CraftsmanNot all sash window insulation methods are the same! There are many different ways to insulate a sash window but as far as we are concerned the most efficient way is the Reddiseal system.
Simply routing a sash window and inserting felt brushes will never give you the same results as the professional methods.
The correct method is to install new timber part beading, fully primed and undercoated prior to arrival the parting bead has an integrated reddiseal weather pile with a transparent fin that seals the sash runs and should also smooth the operation of the slidding sash window too. Methods used by some other companies across the UK involve cutting channels or routing into your 90 plus year old sash windows, this method can and does cause major damage to the delicate joints of your "antique" wooden windows.
Thanks to a brilliant eco-driven government scheme, our customers only pay 5% VAT on any sash window insulation/draft proofing work that we undertake.
