Original stone cills give a property that added bit of aesthetic quality. However, their primary downfall tends to be a poor level of thermal insulation.
The Residence 9 window installation you see includes our Bedrock Cill, designed to replicate stone but in a thermally efficient clad polystyrene; hard to believe how closely it resembles the real thing isn’t it!
Traditional stone can create a thermal bridge resulting in significant heat and condensation. The Bedrock Cill bears a similar authenticity in terms of its appearance but comes with modern features and benefits.
So always consider upgrading your cills when you install R9.
At Residence Collection, we have a range of colours available and can offer everything from timeless classics like Grained White to modern favourites such as Eclectic Grey. Don’t forget, we also offer a dual finish that allows you to find windows and doors that look as good from the inside as they do outside.
