ISG manufacture and install an extensive selection of PVC-U windows, fitted with hardware and complementary accessories.

Using Halo’s versatile System 10 profile – an industry standard from PVC-U systems giant, The VEKA UK Group – our windows can be manufactured in a variety of styles including casement, tilt and turn, vertical sliding, and fully reversible.

Customers have 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.
