Given a long-standing and exclusive relationship, Hi-Seal only uses profiles (purpose moulded PVCu) from the Advance 70 range of products supplied by market leader Selecta to build the frames for their new-fit and replacement double glazing, doors and conservatories. These frames hold high quality sealed glass units and door panels assembled on site. Many producers of windows, doors and conservatory products purchase similar but not identical profiles from a range of suppliers, often to minimise costs. Predictably, this comes at the expense of quality.
The biggest drawback is that the colour of the finish of double-glazing, doors and conservatories built by a company using a varying supply chain may not be consistent, particularly if they are ordered at different times. Exclusively using profile from the Advance 70 system not only avoids this possibility but also makes the conservatories' Hi-Seal manufacture easy to assemble. As well as supplying new windows and doors, our range uniquely includes roofing products designed to fit frames built using its profile.
