We now offer two choices of mechanism when upgrading your box sash windows, to our fully finished, Accoya double glazed sashes.
We can now install your sashes using top of the range Spring balances, instead of the traditional cords and weights approach.
Using balances avoids the need for expensive lead weights as the double glazed units add a significant amount of weight compared to the old single glazed sashes. Spring balances also overcome the issue of binding or jamming that sometimes occurs when obstacles or space is at a minimum in the box frame. Fitting Spring balances allows us to fill in the apperture left behind the old pulley wheel, stopping any draughts finding their way in through the box and cavities of your walls, making your windows even more energy efficient.
