Even the most traditional looking sash windows come with modern elements that make them highly efficient. As standard our sash windows will achieve an energy rating of ‘B’ and a u-value of 1.6/Wm2K and with an argon gas filled unit the windows can achieve an energy rating of ‘A’ and a u-value as low as 1.4W/m2K. The Quickslide sash windows come with colour-matching wool-pile, which helps to block out any draughts, and a new optional weatherbar can add another level of defence against harsh weather conditions.
