uPVC Patio Door & Windows

A substantial property renovation in the affluent Hertfordshire town of Rickmansworth required a complete glazing overhaul for the ground floor rear elevation. The existing uPVC units were old, worn, and detracted from the property’s refreshed aesthetic. The homeowners wanted a bold, modern solution that would complement the renovation’s contemporary design while providing easy garden access and superior thermal performance. The goal was to install black uPVC windows and a matching patio door to create a striking, unified look that would transform the living space and add lasting value to the property.

Our Solution

We supplied and installed a bespoke black uPVC window and patio door system tailored to the renovated property. Black uPVC offers the bold aesthetic of aluminium at a more accessible price point, making it an increasingly popular choice for homeowners seeking a contemporary look. The solution included:

• Black uPVC casement windows with side-hung openings and concealed friction hinges
• Black uPVC French patio door (casement style) with two side-hung opening panels
• A-rated double glazing with argon gas fill and low-E coating for superior thermal efficiency
• Thermally efficient uPVC profiles to reduce heat loss and prevent condensation
• Multi-point locking systems on all windows and the patio door with anti-snap cylinders
• Stainless steel friction hinges for smooth, controlled operation
• Low-threshold cill on the patio door for step-free garden access
• Trickle vents on windows to reduce condensation and improve indoor air quality
• Reinforced frames for added strength and security
• Matching black handles and hardware for a cohesive, premium finish
• Weatherproof seals throughout for superior draught protection
