The Eternal Window

Composite windows are expected to last twice as long as aluminium windows (at least 83 years). This makes our alu clad windows an excellent investment for your home that will pay off in time.

Another huge advantage is that, unlike traditional timber frames which require painting and varnishing, composite windows do not require any special treatment and are virtually maintenance-free.
