Our UPVC double glazed windows and doors are superior to aluminium or wooden framed windows in terms of acoustic insulation, energy efficiency, safety, security, and cost benefits. We offer the best combination of performance and price competitiveness to ensure you receive the best value for your investment.

The impressive performance of our double glazed windows and doors has been independently verified by accredited laboratories, with results surpassing all expectations. Our products comply with BASIX and local council requirements, featuring an average U-value of 1.8—over three times better than the standard aluminium window’s U-value of 5.8. Our double glazed UPVC windows and doors achieve up to 45Rw acoustic rating, whereas standard aluminium or wooden windows provide only 35Rw. The air leakage rate is well below the requirement for air-conditioned buildings, at 0.48 litres and 0.68 litres for inbound and outbound, respectively. Additionally, our products have a water penetration resistance of 1,500 Pascals for 15 minutes before passing the 400 Pascals test, significantly outperforming ordinary aluminium and wood windows, which range from 150-400 Pascals. Our windows passed the ultimate strength test at 3,300 Pascals, compared to the 1,000 Pascals of competitor aluminium windows.

The UV weathering test results show that our German profile supplier meets the quality requirements for hot climatic zones, withstanding radiation up to 180kcal/cm squared/a. Further tests in regions with global radiation of 200kcal/cm squared/a are showing promising preliminary results.

The hardware on our windows and doors has been rigorously tested for the equivalent of 10,000 operation cycles, ensuring high performance in terms of reliability, durability, safety, and security. Due to the additional stress from the extra glass weight in the Insulated Glass Unit, we use only the best heavy-duty hardware from trusted suppliers. We offer hardware for any application, with free advice on the specification and use of child safety devices, locks, restrictors, anti-vandal, and security features.

Please note that while these results provide a general overview, even greater performance can be achieved in many applications. For instance, although a double glazed window carries a certain Rw rating indicating acoustic insulation qualities, performance variations across frequency ranges can be further enhanced by adjusting the glass width and lamination based on noise exposure or application.
