1 Advantages of Double Glazed upvc Windows & Doors WEEDOO SA Technical Support by Jason Jorgensen

2 Advantages of upvc Windows and Doors Heat and Cold insulation Sound insulation Water tightness

3 Dust proof and air tight High impact resistant and robust Easy maintenance

4 Burglar Resistant Galvanised Steel Reinforcing encapsulated in the main reinforcing chamber. Multi-Point locking systems on all opening sections All glass used in our sealed units are Toughen Safety glass. Always 2 layers of Toughened glass = double security
