Questions
Good to know
What’s the difference between standard and flush?
On a flush window the opening sash sits level with the outer frame, for a cleaner, more traditional look. Standard casements have the sash slightly proud of the frame.
Can I have different colours inside and out?
Yes. Dual colour is available, for example anthracite grey outside and white inside.
Are aluminium windows cold?
No. Modern thermally broken profiles separate the inner and outer aluminium, and with good glass they reach U-values of 1.0 W/m²K.
