Dekko Window Systems has underlined the technical and commercial advantages of its Infinity Flush sash windows, following a recent installation by Bespoke Frames that paired the system with aluminium bi-fold doors on a contemporary residential property.

In this project, the homeowner selected aluminium bi-folds to create large glazed openings and a strong indoor-outdoor connection. To maintain visual continuity across the façade, Infinity Flush sash windows were installed throughout the rest of the property.

Key aesthetic features include:

• True flush external appearance, replicating traditional timber sightlines
• Sharp, clean frame lines to match aluminium systems
• Graf welded or seamless welded corners for refined detailing
• Colour and finish options designed to coordinate with aluminium doors

The result is a cohesive, minimalist exterior where PVC-U windows sit comfortably alongside aluminium elements without visible compromise.

While aluminium systems are often chosen for their contemporary look, PVC-U continues to offer superior thermal efficiency at a more accessible price point.

Infinity Flush delivers:

• Competitive U-values, supporting compliance with current Building Regulations
• Improved insulation compared to many standard aluminium window systems
• Reduced heat loss across the property envelope

According to Steve Collett, Sales Director at Dekko, this balance is central to the product’s appeal:

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. Installers can offer a sleek, architectural look with far better U-values and a significantly more competitive price.

Dekko also manufactures the Residence Collection fully Graf welded, including the R7 system, providing installers with alternative flush sash solutions depending on project style and specification.

For installers targeting high-end residential projects, Infinity Flush offers:

• Aluminium-style aesthetics
• Enhanced energy efficiency
• Competitive pricing
• Flexible welding and finish options

The system demonstrates how PVC-U continues to evolve, delivering modern design credentials without sacrificing performance or commercial viability.
