DIY PVC double-glazed windows
Prices | Order Form
Double-glazed PVC-U windows are maintenance-free; the colour goes all the way through. They will not rot, corrode, flake, tarnish or fade.
Because PVC-U is a natural insulator, the frame actually adds to the value of double glazing and condensation is virtually eliminated. Because our units are double weather stripped draughts are a thing of the past, but with the use of the project-stay hinge, gentle draught-free ventilation can be introduced.
Southern PVC Systems' replacement windows are designed and developed to meet the most severe weather conditions to meet the latest EU standards.
Window frames made from PCV-u are extremely secure and locking handles are fitted as standard.
All products are made in our own factory in Bristol and manufacture is carried out to a nationally laid-down standard in accordance with the codes of practice of the British Plastics Federation Window Group.
