What You Need to Know About uPVC
Better insulation & solar control = Lower energy bills + Year-round comfort
What is a U-Value?
The U-value measures how effectively a material resists heat transfer. A lower U-value indicates better insulation, meaning less heat escapes in winter and less heat enters in summer. This results in a more stable indoor temperature, reducing the need for artificial heating and cooling and lowering energy costs. uPVC windows and doors are designed with low U-values, ensuring superior thermal performance for a comfortable home year-round.
What is SHGC?
The Solar Heat Gain Coefficient (SHGC) measures how much solar radiation passes through a window and contributes to indoor heat. A lower SHGC means less heat is transmitted, helping keep interiors cooler in hot weather. This is especially important in sunny climates where excessive heat gain can lead to high cooling costs. Our uPVC doors and windows are optimised for low U-values and appropriate SHGC ratings, striking the perfect balance between insulation and solar control for maximum energy efficiency.
Superior Noise Reduction with UltraLine uPVC
Our UltraLine profile is designed to significantly reduce external noise, offering up to 27 decibels of sound reduction on its own. When combined with the right glazing, the overall noise reduction can be even greater, creating a quieter and more peaceful indoor environment.
Why do uPVC Doors and Windows Outperform Aluminium
uPVC windows and doors offer superior energy efficiency and durability without the ongoing maintenance that aluminium requires. Designed to withstand the elements, these frames remain weather-resistant and low-maintenance, saving you time and effort compared to aluminium, which needs regular upkeep to stay in good condition.
