How energy efficient are sash windows?

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 weather bar can add another level of defence against harsh weather conditions.
