PVCu Windows
Our A-rated PVCu windows feature Liniar's EnergyPlus profiles with triple glazing, achieving thermal efficiency as low as 0.84W/mK. Manufactured in the UK, they reduce heat loss and lower energy bills while offering security through multi-point locking systems. Available in casement, tilt & turn, bay, and sash designs to suit traditional or contemporary properties.
Composite Doors
Durable composite doors combine advanced thermal efficiency with high-security locks and reinforced frames. Available in full or half-panel designs, French, patio, or bi-folding styles, they enhance kerb appeal while providing low-maintenance durability. Internally beaded glazing units prevent external tampering, ensuring long-term performance.
Conservatories
Bespoke conservatories and orangeries are tailored to individual needs, offering classic or modern designs like Lean-To, Edwardian, or glass extensions. Tiled roof options and skypods maximise natural light while maintaining thermal efficiency. All structures are built to integrate seamlessly with existing properties, expanding living space affordably.
Single Storey Extensions
From design to completion, we deliver single-storey extensions incorporating flooring, lighting, and electrics. Our project-managed approach ensures hassle-free installations, with lightweight tiled roofs and energy-efficient materials. Ideal for creating kitchens, lounges, or home offices without requiring planning permission in most cases.
Roofline Products
PVCu roofline solutions include gutters, downpipes, and fascias in multiple colours and styles. Designed for durability with high-gloss finishes, they require no painting and withstand extreme weather conditions. Carports provide vehicle protection with self-supporting structures capable of withstanding 146mph winds and heavy snow loads.
