Premium Doors: Luxury and Performance Combined

Premium doors redefine the entrance to your home with exceptional craftsmanship, advanced security and industry-leading thermal performance. These doors combine striking aesthetics with cutting-edge functionality, featuring elite brands such as Internorm, Velfac, Rationel, Smarts, Zyle Fenster and Dutemann.

Built for Energy Efficiency

Passivhaus-certified premium doors achieve outstanding insulation and energy efficiency, reducing heat loss and energy bills. With U-values as low as 0.62 W/(m²K), they deliver industry-leading thermal performance. Structural warm edge spacer bars and insulating core materials further optimise performance, reducing condensation and maintaining a stable indoor climate.

Versatile and Customisable

Premium doors offer a wide range of configurations, including lift-slide doors, ultra-thin aluminium sliding doors, bi-folding doors, main entrance doors, side entrance doors and utility doors. Bespoke sizing allows for extra-wide entrances, with sliding door panels up to 4m² per panel, creating uninterrupted views and a seamless connection between indoors and outdoors. A vast selection of frame colours, finishes and handle designs ensures a perfect match for any architectural style.

Security and Comfort

Premium doors are equipped with robust multipoint locking systems, providing unparalleled protection against forced entry. High-security glazing options—including laminated, toughened and obscure glass—enhance safety and privacy. Engineered with reinforced aluminium and composite structures, they ensure exceptional durability, while advanced weather seals maintain warmth and comfort in all seasons.
