Black uPVC Windows

A residential property in Dunstable required a full window replacement after the existing white uPVC units had yellowed, become draughty, and failed to complement the property’s exterior. The owners wanted a bolder, more contemporary look without the higher cost of aluminium, and were keen to improve thermal comfort and security at the same time. The goal was to install black uPVC windows throughout, delivering a striking modern appearance alongside better energy efficiency and low maintenance.

Our Solution

We supplied and installed black uPVC double-glazed windows across the front, side, and rear elevations. Black uPVC offers the visual impact of aluminium with the thermal performance and value of a uPVC system. The solution included:

• Black uPVC casement windows with side-hung openings and concealed friction hinges
• Deep black foil finish on both interior and exterior faces for a consistent, contemporary look
• A-rated double glazing with argon gas fill and low-E coating for improved thermal insulation
• Multi-chambered uPVC profiles to reduce heat loss and prevent condensation
• Acoustic-enhanced glazing to front-facing rooms to reduce road noise
• Multi-point locking systems with anti-snap cylinders and black security handles
• Trickle vents for compliant background ventilation
• Reinforced frames for added strength and security
• Matching black sills, trims, and hardware for a cohesive finish

Installation Process

• Carried out a detailed pre-installation survey with laser measurements of every opening
• Confirmed window styles, glazing options, and black finish with the owners
• Protected internal floors and furnishings before work began
• Removed the existing windows carefully to preserve surrounding brickwork and internal plaster
