uPVC Double Glazing is the Future

In many countries around the world, double glazing is a legal requirement because of its sustainability and wide ranging benefits compared to regular windows and glass doors. With the ever increasing concerns about climate change, energy efficiency is more important now than ever and double glazing can vastly improve the efficiency of your heating and cooling system by reducing the thermal transfer through your windows and glass doors.

uPVC is scientifically backed as a sustainable building material. It is recyclable, durable, easy to maintain, fire resistant and contributes to a higher standard of living. Add value to your home, cut energy bills and do your bit for the environment by installing uPVC double glazed windows and doors.

High Quality Product - Secure, Long Lasting & Easy to Maintain

We use only the highest quality materials and construction methods which means we can stand behind the durability of our products. Our panels are well suited to the extremes of the South Australian climate with high resistance to UV radiation, salty air, wind and bushfire resistant properties.

Your windows and doors will have high impact strength and will not corrode, rot or be eaten by termites. The triple chambered profile provides maximum insulation against noise and temperature. Galvanised steel with fusion welded joints provide strength and rigidity. Twin compression seals give advanced protection against air and water and thermal insulation exceeds Australian Standards.

A wide variety of styles of windows and doors are available including tilt & turn, awning, single & french doors, fixed lights, casement and sliding or tilt and slide. We can customise our products and installation to meet the requirements of any project. With over 12 years of experience, we have the resources and knowledge to recommend and create the best solutions for your needs.

“We were apprehensive about how the PVC would look in our turn of the century villa, but they look amazing!” - Sarah on Facebook

“They tilt one way and they open the other which means you have access right the way around them so you can get to clean from the inside and out”

“Security is much better with the locking system on the windows and doors” - Carl, Reynella East

“Having been a building and developer for 30 years, I really wanted to have the best product in my own house”

Warmer in Winter & Cooler in Summer

Up to 49% of inside heat is lost through conventional windows in winter as heat travels through normal glass relatively easily. The greater the temperature difference between the outside and the inside, the greater the heat transfer so the harder your heater works the more hot air you are losing.

Double Glazed insulated glass units can prevent up to 69% of the heat loss of conventional windows. Quality construction including welded joints and sturdy seals ensures no air escapes through the cracks and means the product will last and provide continued high performance for many years and in the weather extremes we see here in Adelaide.

“It doesn’t cool down as much at night and therefore the air conditioning and heating system has much less load on it”

“Heating bills are down, comfort level are up”

“Double glazing keeps an even temperature indoors through summer and winter” - Carl, Reynella East

Noise Reduction

Adelaide is seeing an increase in construction and living density and a number of new highway projects which are increasing residential noise levels for many people. Our windows and doors can reduce noise from outside by up to 44db. For comparison, ear plugs generally only reduce noise by 33db.

Those living near busy roads, railway lines or the airport will get their peace and quiet back and increase the value of their properties.

“The sound improvement… we have a bit of a noisy road here by Clarendon and when trucks go past, with the windows shut, you don’t hear a thing...”

“Our 28 year old house that is one street off of highway needed a face lift and so we called Double glaze windows… ...House looks great, room is cooler and so much more quite.” - Michelle on Facebook

“Thanks to Paul and the crew for a great job with our new windows at Brighton replacing the old timber windows with some tilt and turn PVC windows.. they look great and the double glazing has certainly kept out some of the noise from the neighbours.” - Phil on Facebook

“Outside sounds are more restricted and makes for a much quieter household” - Carl, Reynella East
