Fix the glazing, not the character

The installation of vacuum insulated glazing (VIG) occurs directly within your existing timber sashes to maintain window aesthetics while providing thermal performance that exceeds both building code standards and double-glazed window efficiency.

Our VIG units deliver performance levels which match or go beyond current energy standards to protect your windows from future regulatory changes.

The reglazing, combined with refurbishment and draught-proofing, brings a wide range of benefits.

The system provides improved external noise reduction and prevents condensation and rattling while delivering excellent thermal insulation to maintain indoor warmth during winter months.

Better glazing. Warmer nights. Lower bills.

It’s simple: windows are mostly glass. The thermal efficiency of a window depends 80–90% on its glazing system so achieving proper glazing selection leads to optimal results.

That’s why we use vacuum insulated glazing (VIG) in all of our projects.
