Combining impressive functionality and design, these windows offer the high quality expected from market-leading home improvements. These windows provide an excellent aspect, with the System10 profile reducing sightlines through a chamfered slimline edge. They can also be upgraded to conform to PAS24.

Also available is the Halo Rustique range which boasts a host of innovative extras, including single-leg beading options. The profile provides improved rigidity and performance, plus additional strength and thickness by incorporating an innovative design of five enclosed chambers.

Added thermal performance can be gained by including a thermal insert. This high-performance thermal insert is a multi-broken chambered profile which fits into the window design. This cleverly designed feature keeps your home warmer, saving you money on your energy bills.
