Aluminium exterior door L928 made to order

Aluminum exterior door with 92 mm profile and exceptional thermal performance (Ud 0.85 W/m²K). Quadruple glazing and triple EPDM sealing for superior insulation and weather resistance.

The L928 is an aluminum exterior door engineered with precision to meet the exacting standards of residential and commercial properties. The expanded 92 mm profile and 80 mm frame depth create a structurally robust system, proportioned for contemporary façades and high-performance buildings.

Construction relies on 3 mm aluminum thickness with articulated 34 mm thermal break technology that decouples exterior and interior layers, eliminating thermal bridges entirely. The quadruple glazing (44.1 triplex / 5 mm Satinato / 44.1 triplex) delivers refined light transmission and superior acoustic insulation. Triple EPDM gaskets ensure flawless sealing against wind, moisture, and thermal cycling over decades of use.

Thermal performance at Ud = 0.85 W/m²K positions this door firmly in the premium segment, verified to ift Rosenheim standards. The combination of satin glazing with acoustic properties and articulated profiling significantly reduces external noise while maintaining year-round energy stability. System longevity is assured through corrosion-resistant materials and finishes designed to withstand prolonged exposure.

Size flexibility—up to 1200×2500 mm per single leaf—accommodates ambitious architectural projects. Standard opening configurations and custom adaptations make L928 a versatile solution for residential façades, contemporary commercial spaces, and buildings with advanced insulation requirements.

This door integrates seamlessly with minimalist interiors, contemporary design languages, and spaces prioritizing thermal and acoustic comfort. Aluminum's adaptability permits varied finishes and coordinated solutions with premium window and flooring collections.

The thermal coefficient Ud is 0.85 W/m²K (certified by ift Rosenheim), placing this door in the superior performance category for modern exterior doors. The reduced heat loss value is due to the deep 92 mm profile, the 34 mm articulated thermal break, and the quadruple glazing with three layers of protection. This guarantees consistent interior comfort and reduced heating costs in the long term.

The door is made from 3 mm aluminium mounted on a frame system with 80 mm depth and a complete 92 mm core. The structure is reinforced with articulated thermal break panels, which prevents condensation and heat loss. The aluminium used is anodized and corrosion-resistant, ideal for diverse climate conditions and intense sun exposure, requiring only light periodic cleaning.

The glazing is quadruple (4 panes), structured as 44.1 triplex / 5mm Satinato / 44.1 Triplex. This means two laminated safety glasses (44.1) with triplex laminate on the outside, a 5 mm gap, and satin-finished glass inside for light diffusion and additional protection. This configuration provides superior acoustic insulation, impact resistance, and solar ray control, being essential for main entry doors and high-traffic areas.

Sealing is achieved through three EPDM profile gaskets (3-point), strategically placed on the frame to completely block water, wind, and dust entry. The 92 mm profile thickness and integrated thermal break create a complete climate barrier that maintains balanced pressure on both sides of the door. The combination of quadruple glazing and elastic EPDM gaskets ensures resistance to sudden temperature and humidity changes without compromising ease of opening.

Standard dimensions are 1100 × 2300 mm, and for a single leaf you can go up to 1200 × 2500 mm. For non-standard openings, this door can be manufactured to order in any size up to the maximum limits, allowing perfect integration into any building structure. The team of specialists in the showroom can take measurements and make personalized recommendations directly on site, ensuring a perfect fit.

The frame system has a depth of 80 mm, making it compatible with most walls with standard insulation from concrete, brick, and mixed masonry. Installation requires qualified professional teams to ensure perfect alignment and sealing according to DTU standards. If you are replacing an existing door, we recommend complete removal of the old frame and repair of any micro-cracks, which guarantees maximum performance over time.
