uPVC Sliding Doors & Windows

A modern detached house in Berkhamsted required a complete glazing solution for the rear elevation. The existing patio door was old and difficult to operate, while the adjacent windows were mismatched and inefficient. The homeowners wanted a cohesive, low-maintenance solution that would provide easy garden access, improve thermal performance, and enhance the property’s contemporary aesthetic. The goal was to install uPVC sliding doors and matching windows throughout the rear of the property.

• White uPVC sliding patio door with slimline sills for easy garden access
• Matching white uPVC casement windows flanking the sliding door
• A-rated double glazing with argon gas fill and low-E coating for superior insulation
• Multi-point locking system on the sliding door with anti-snap cylinders
• Concealed roller system for smooth, quiet sliding operation
• Side-hung casement windows with concealed friction hinges
