Services
Bi-Fold Doors
Protect Upvc installs bi-folding doors that merge indoor and outdoor spaces with slim, energy-efficient profiles. These doors maximise natural light while offering thermal insulation through polyamide thermal breaks and optional cellular foam cavities. Available in multiple RAL colours, they feature secure multi-point locking systems and seamless sliding mechanisms for patios or garden access.
Sliding Doors
Our sliding doors provide panoramic views and low-maintenance functionality with precision-engineered tracks. Designed for durability, they incorporate internally beaded glazing for security and come in powder-coated finishes. The thermally broken profiles reduce heat transfer, ensuring energy efficiency while maintaining sleek, modern aesthetics for residential properties.
Aluminium Windows
Aluminium windows combine strength with contemporary design, featuring polyamide thermal breaks and gaskets to enhance insulation. Compliant with building regulations, they offer slim sightlines and powder-coated finishes. These windows are ideal for properties requiring durable, secure, and thermally efficient glazing solutions with minimal maintenance.
UPVC Windows
UPVC windows provide cost-effective, energy-efficient glazing with A-rated performance as standard. Constructed from weather-resistant materials, they include steel reinforcement options and triple glazing for enhanced security and insulation. Available in casement, tilt-and-turn, or vertical slider styles, they suit both residential and commercial properties.
Roof Lanterns
Roof lanterns flood interiors with natural light using thermally broken aluminium or UV-stabilised UPVC frames. Designed for extensions or flat roofs, they feature self-cleaning glass and solar control options to regulate temperature. Bespoke sizes ensure a tailored fit, combining architectural elegance with energy-efficient performance for modern living spaces.
