Smooth & Stylish Spiral Balance Sash Windows

Update your property with beautifully engineered Spiral Balance windows that offer sleek vertical sliding operation, superior insulation, security, and lasting style

Spiral Balance

Sliding Sash Spiral Balance windows are a modern version of windows designed by Robert Hooke back in the 17th century. The weight and cord attached to it, which initially were the opening mechanism, have been replaced by spiral balance manufactured by Caldwell for easier sliding. The traditional English look has however been entirely preserved. Vertical opening allows for the space around the window to be fully utilised

MATERIALS

Timber

For the production of frames we use the following species of wood: pine, oak and meranti. Other types of timber are available on customer’s request. We use 80­100 year old pest­free timber coming from trusted FSC­certified suppliers.

Hardware

We use Caldwell and Mighton hardware which is chosen individually to every project.

Glass

Windows may be single, double or triple-glazed. Triple-glazed units have the best insulating properties. We offer a large selection of glass types:
– soundproof
– esg
– energy efficient
– ornamented
– fireproof
– anti burglar
– solar control
we also offer one­way mirrors, other types of custom made glass and warm spacer bars which increase thermal insulation of a window unit.

COLOUR

Frames are available in a wide range of RAL colours or any other specified by the client. We use weather­resistant Teknos Gori paints which are very durable and resistant to sunlight. We offer both opaque and translucent Teknos Gori paints. Dual colour frames are available upon request.
