Dekko Window Systems says that installers looking to deliver the clean, contemporary aesthetics homeowners increasingly demand now have the perfect solution, thanks to its Infinity flush sash windows.
A recent project by long-term Dekko customer Bespoke Frames has highlighted how the PVC-U Infinity flush sash blends with aluminium doors, while delivering outstanding thermal performance.
The homeowner opted for aluminium bi-folds to maximise glazed areas, pairing them with Infinity flush sash windows for a consistent, minimalist look across the whole property.

According to Steve Collett, sales director at Dekko, the project perfectly demonstrates the system’s unique appeal.
“This stunning and ultra-modern property really shows what Infinity Flush can do,” Steve said. “The windows blend in perfectly with the aluminium doors, giving that sleek, architectural look customers want, but with far better U-values. Infinity Flush is the ideal choice when homeowners love the aluminium aesthetic but don’t have the budget to go full aluminium across the whole house.”
Dekko’s Infinity Flush sash windows come Graf or seamlessly welded as standard. Dekko also offers the Residence Collection fully Graf welded.
“R7 with a Graf weld is also a perfect alternative for this kind of installation,” Steve added. “Whether it’s Infinity Flush or Residence, installers can give their customers a sharp exterior look that matches aluminium bi-folds and sliding patio doors, often with better thermal performance, and at a significantly more competitive price point.”
