Using the Halo System 10, ISG manufacture and install an extensive selection of PVC-U windows, fitted with fully certified hardware and complementary accessories.

Our windows can be manufactured in a variety of styles including casement, tilt and turn, and fully reversible windows, with a choice of white, woodgrain and an array of factory foiled finishes to suit any property.

Featuring an integral pre-applied gasket system means that frames can be glazed quickly and efficiently as the seal is welded into position. This greatly improves weathering performance and security, while the low line appearance maximises visual glass area and minimises the seal sightline for a more pleasing aesthetic look.

Through frame or through sash Trickle ventilation will be incorporated where specified by the client to meet current building Regulations. Additional over glass ventilation can be included if required by the client. Kite Mark windows are manufactured following the Halo technical fabrication manual and independently verified through external audit and testing in association with BSI Product Services.

ISG also offers a variety of specialist glass, catering for clients with specific requirements in terms of acoustic performance, thermal control, and even integral blinds.
