Harmony - The Latest Developmet in Replacement Windows
The Harmony window with its unique combination of performance and good looks has a proven pedigree of durability and quality.
The product uses high quality box section aluminium extrusions throughout its range, providing consistant standards of accuracy that are simply not possible with other products which are entirely constructed from PVCu. Harmony's internal PVCu skin is permanently bonded to the aluminium section using a specially formulated polyurethane foam which ensures that the qualities of these two materials are brought together to give you the best of both worlds.
Every Aluminium extrusion conforms to the quality levels laid down by BS 1474. The high strength of the Harmony window is combined with a slimline appearance.

Slimline Feature Vent
An attractive exterior look is achieved by the use of crisply chamfered aluminium profiles giving a "featured vent" appearance avoiding the bulky look of other alternative materials.
The internal PVCu cladding is designed to accept concealed shootbolts cleverly hidden inside the profile itself, this gives the highest possible level of security with the minimum number of visible parts.

Security
Harmony is designed to incorporate the very latest high security locking features, and has successfully completed testing that equals the requirements of BSI PAS 011 "Improved security of domestic windows 1994". Shoot-bolt locks and High Security hinges which give effective 5 point locking to each opening sash are anchored to the main aluminium profile, which is up to 25 times stronger than an equivalent PVCu section.
