Double Glazed Windows & Doors - Styles
We realise when you are building (or renovating) your dream home, you want everything to be absolutely perfect. That's why we take the time with you to listen carefully to exactly what YOU want, and then work with you to plan your double glazed windows or doors.
Then we custom-make them for you using our unique double glazing system. Your uPVC windows and doors
become a versatile design feature, without the constraints of having to use standard sizes. The featured styles
here are some of our more popular styles, but of course you are able to choose all sorts of different angles,
curves and semi-circle shapes, all using our uPVC window frames & double-glazing technology, to achieve
your desired look.
If you have an architect or building designer working on your project, they will also love CertainTeed uPVCframed
double glazed windows. We’ll work closely with them, supply them with all the technical data they need and ensure the whole project runs smoothly for them.
Range of Windows and Doors
 |
Double Hung
Two sashes slide vertically past each other. Real space savers with excellent ventilation. They open smoothly for a lifetime, with tilt-in sashes for easy cleaning. Importantly, the balance system is engineered with a 19mm stainless steel coil that applies a constant tension.
Sashes lift & lower easily ... and stay where you put them. They never need adjusting. The CertainTeed system outperforms both spiral and weights and cords systems. |
 |
Sliding Windows
Mounted horizontally to slide past each other. CertainTeed designs slide on quality rollers for a lifetime of easy opening. Excellent ventilation. Our 3 basic styles give you lots of choice about which part of the window you want to open. Sashes lift out for cleaning.
Three styles shown:
End vent glider, centre vent glider, double glider. |

Bay and Bow Windows

Usually in the Double Hung style but able to be customised to your needs, Bay and Bow Windows are especially created to take advantage of great views and natural lighting.
They also create a sense of space and really add to the character of the home.
