Secure timber flush casement windows with a potential U-value of 1.2 W/m²K in double glazing or 0.90 W/m²K in triple glazing.
Suitable for most applications.
Particularly suitable for unlisted properties where replacement windows are required, or for new build projects which need to achieve all of the relevant building regulations but Passiv-Haus level performance is not required.
Hardwick Timber Flush Casement Windows have a number of modern features implemented with the goal of maintaining the general proportions and sightlines wherever possible. The windows offer improved energy efficiency and robust construction while still appearing to be a traditionally styled product. They provide architects and specifiers working on most building projects with a reliable and functional solution, combining security, functionality, and modern design.
