Why Choose uPVC/PVCu Windows for Your Trade Projects?

uPVC, also referred to as PVCu, is the industry standard for modern, energy-efficient window installations. Dekko’s uPVC windows offer:

• Outstanding Thermal Efficiency: Multi-chambered profiles and advanced glazing options achieve U-values as low as 0.8 W/m²K, supporting compliance with the latest energy regulations.
• Superior Security: All systems are reinforced with galvanised steel and compatible with high-security hardware, meeting PAS 24 and Secured by Design standards.
• Low Maintenance: Unlike timber, uPVC windows require minimal upkeep—no painting, just occasional cleaning.
• Design Versatility: Choose from flush, sculptured, or chamfered profiles, a wide range of colours and finishes, and multiple opening styles to suit any project.
• Sustainability: Fully recyclable profiles and lead-free manufacturing support your clients’ environmental goals.

The Residence Collection: Premium Timber-Effect Windows
