How can trade windows help you meet energy targets?

With ever-stricter UK building regulations, energy performance is no longer optional. Our double glazed uPVC and aluminium windows come with market-leading thermal performance as standard, delivering exceptional thermal efficiency and helping to reduce energy bills and futureproof homes. Every product meets or exceeds current building regulations, providing both installers and end-users with complete peace of mind.

• Many of our trade uPVC windows achieve A+ energy ratings
• Flush casement windows and sash windows can be upgraded with triple glazing
• All aluminium products are thermally broken to minimise heat transfer
• U-values as low as 1.2 W/m²K can be achieved depending on specification

This level of energy efficiency helps homeowners cut costs while helping you deliver compliant, futureproof solutions.

Customisation to suit every project

No two homes are the same. That’s why Dekko offers a wide selection of colours, glazing options and finishes to help you match client expectations and make installations easier to sell.

From authentic timber-effect finishes to bold RAL colours, our trade windows can be tailored to suit both modern and traditional homes.
