Services
Double Glazed Windows
Our double glazed windows combine durability, security, and thermal efficiency. Constructed with two panes of glass and insulating gas, they reduce heat loss and noise pollution while enhancing property aesthetics. Available in uPVC, aluminium, and heritage styles, they cater to both modern and traditional homes. Customisable options ensure seamless integration with architectural designs.
Double Glazed Doors
We offer robust double glazed doors with advanced locking systems for enhanced security. Options include uPVC, composite, and bi-fold designs, balancing style and functionality. These doors improve energy efficiency, reduce external noise, and add value to properties through sleek, contemporary finishes.
Warm Roofs
Warm roofs transform conservatories into year-round living spaces. Constructed with insulated panels and weatherproof finishes, they prevent overheating in summer and heat loss in winter. Available in slate or shingle styles, they provide durability and aesthetic appeal while complying with thermal efficiency standards.
Lantern Roofs
Lantern roofs flood interiors with natural light through minimalist glass designs. Ideal for flat roofs, they feature self-cleaning glass and thermal insulation for energy efficiency. These structures create a striking visual focal point while maintaining comfort and reducing reliance on artificial lighting.
Rubber Roofs
Firestone RubberCover EPDM roofs offer durable, waterproof solutions for commercial and residential properties. Lightweight and eco-friendly, they require minimal maintenance and resist extreme weather. Flame-free installation ensures safety, while a 50-year lifespan provides long-term value for flat roofing projects.
