Three-Leaf Aluminium Sliding Door, Ready to Install

The ALU-SLD-4 is a three-leaf aluminium sliding door perfect for timber garden structures, summerhouses, and premium outdoor rooms. Combining a robust RAL7016 anthracite-painted aluminium frame with tempered double glazing and a spruce timber casing, it delivers the contemporary aesthetics and thermal performance that modern garden building projects demand.

Premium Aluminium Sliding Door for Timber Structures

At 2660 mm wide and 2072 mm tall, the ALU-SLD-4 creates an impressive, light-filled opening that connects indoor and outdoor spaces. The three sliding leaves glide on precision tracks within a clear aperture of 2470 mm, while 95 mm side profiles ensure a clean, architectural finish at the jambs.

The frame and all door leaves are finished in RAL7016 anthracite grey — one of the most requested contemporary colour specifications for garden offices, lounges, and other structures. Rubber sealants integrated into the spruce casing maintain a weathertight perimeter, protecting against draughts and water ingress.

Tempered double glazing meets both safety and thermal performance requirements, making this door suitable for year-round installations where comfort and durability are essential. The ALU-SLD-4 is supplied ready for installation into the corresponding wall opening and is compatible with Dadsons’ timber building systems.

Why choose Sliding Door ALU-SLD-4?

Robust Aluminium Construction

Both the frame and sliding leaves are manufactured from heavy-duty aluminium. The material resists corrosion, warping, and weathering. It provides long-term structural rigidity with minimal maintenance and reliable performance in demanding outdoor conditions.

RAL7016 Anthracite Finish

Frame and leaves are factory-painted in RAL7016 anthracite grey, one of the most sought-after finishes for contemporary garden buildings and outdoor rooms. The consistent colour coating ensures a premium appearance that complements both dark and light timber exteriors.

Tempered Double Glazing

Safety-certified tempered glass in a double-glazed unit reduces heat loss while meeting European safety standards for impact resistance. This makes the ALU-SLD-4 a suitable choice for insulated garden offices, saunas, and year-round structures.

Spruce Casing with Rubber Sealants

The surrounding casing is crafted from spruce timber, providing a natural transition between the aluminium door unit and the timber building wall. Integrated rubber sealants around the perimeter create a weathertight seal to prevent draughts and moisture ingress.

Frequently Asked Questions

The ALU-SLD-4 has an overall frame size of 2660 mm wide by 2072 mm tall. The clear sliding aperture between the fixed side profiles is 2470 mm, with 95 mm profiles at each side.

RAL7016 anthracite grey is factory-applied on all aluminium components.

The ALU-SLD-4 features tempered double glazing, which provides improved thermal insulation over single glazing and meets safety glazing standards. For highly insulated year-round buildings, the performance should be evaluated alongside the wall system and overall building specification.

The surrounding casing is manufactured from spruce timber and is fitted with rubber sealants to create a weathertight joint between the door unit and the wall opening. This helps prevent draughts and water penetration at the perimeter.

Spruce is a natural timber material, so wood texture and grain appearance may vary between units. This is noted in the product documentation and is considered a natural characteristic of the material rather than a defect.

The ALU-SLD-4 is compatible with a wide range of Dadsons’ timber garden building systems, including the Faxwerk modular structure which lists sliding glass doors as a standard integration option. Compatibility with specific wall thicknesses, sized or building systems should be confirmed at the time of order.
