Understanding UPVC in Double Glazed Windows and Doors

UPVC stands for Un-plasticised Polyvinyl Chloride, a rigid plastic widely used in the manufacture of double glazed windows and double glazed doors. Its key benefits include:

• Resistance to rot and biological decomposition, preventing termite attraction.

• Weather resistance with minimal maintenance.

• High impact toughness.

• Thermal efficiency, contributing to energy efficient windows.

• Stability in extreme temperatures.

• Recyclability through reshaping at high temperatures.

PVCu vs UPVC in Vinyl Double Glazing

There is no difference between PVCu and UPVC; both represent Un-plasticised Polyvinyl Chloride. The benefits of UPVC double glazed windows are consistent, regardless of the term used.

Reinforcing Double Glazed Windows: Steel or Aluminium?

Both steel and aluminium reinforcement are effective for double glazed windows. Competitors may make exaggerated claims, but steel, though stronger, can rust if its galvanization is compromised. Aluminium, while less likely to rust, is slightly weaker. Swarf removal during screw insertion can lead to localized rust in steel, which does not spread. We manufacture in Sydney to your specifications, ensuring flexibility and quality in double glazing.

Choosing Toughened or Laminated Glass for Double Glazing

Both toughened and laminated glass are safety glass options for double glazed windows and doors. Toughened glass shatters into small, blunt pieces, minimizing injury risk. Laminated glass cracks but remains intact due to a laminate layer, providing better security and insulation. Laminated glass is thicker and heavier, affecting hinge wear. Legal requirements may dictate safety glass in certain areas. Choose based on your specific needs.

Caring for UPVC Double Glazed Windows and Doors

Clean and oil visible moving metal parts, like door locks and window hinges, once or twice a year. Avoid using liquid detergent on seals; instead, use cream cleanser in warm water. Keep sliding patio door tracks clear of mud, grit, and dust, and avoid lubrication to prevent particle buildup.

Internal vs External Glazing in Windows

Internally glazed windows have glazing beads inside, enhancing security by preventing glass removal from outside. Externally glazed windows have the beads outside. Internally glazed PVCu systems often feature welded transoms and mullions, while externally glazed systems use mechanical fixing. For higher buildings, internal glazing is easier as most work is done from inside. We offer both options for our double glazed windows and doors.

UPVC Double Glazed Windows in Australian Conditions

Contrary to some claims, UPVC double glazed windows are highly durable in Australian conditions. These windows are made from rigid plastic, outperforming wood and aluminium in various aspects. Some salespeople may spread misinformation due to a lack of technical knowledge or to secure sales. Many of these companies are now developing UPVC windows after recognizing their superior performance. Trust the durability and quality of UPVC double glazed windows from a reputable manufacturer in Sydney.

Secondary (Double) Glazing

Secondary glazing involves fitting an additional window inside your existing one, enhancing insulation and noise reduction, especially useful in noisy areas or heritage buildings where window replacement is not feasible.
