Aluminium exterior door L280 made to order

High-performance aluminium exterior door with advanced thermal insulation and quadruple glazing. Premium engineering for contemporary homes and buildings demanding superior energy efficiency and weather protection.

The L280 series represents a premium external door solution engineered for residential and commercial projects prioritizing thermal performance and long-term durability. Aluminium profiles at 3 mm thickness are reinforced with an articulated thermal break of 34 mm, delivering a thermal coefficient of 0.85 W/m²K — among the finest in premium aluminium systems. The total 92 mm system depth ensures robust, stable construction optimal for generous door openings.

Glazing features a sophisticated quadruple configuration — two outer 44.1 mm triplex panes separated by 5 mm Satinato film — providing exceptional acoustic insulation and UV protection. Three EPDM perimeter gaskets prevent water and cold air infiltration, even under extreme weather conditions. The system has been validated to ift Rosenheim international standards, confirming compliance with European performance benchmarks.

The superior thermal performance of this profile makes it especially suitable for cold climates and mountain regions where interior heat retention is critical. The 92 mm leaf thickness and 80 mm frame depth deliver exceptional insulation capacity and high resistance to deformation. Standard openings up to 1100×2300 mm are available, with expansion to 1200×2500 mm for single configurations.

Customization is available in diverse RAL colours and surface finishes, allowing seamless integration into any architectural concept — from minimalist contemporary homes to contemporary restorations maintaining traditional balance. The system supports both swing and sliding operations, depending on available space and design preference.

Ideal for transition spaces between interior and exterior, such as terraces, atriums, primary entrances, and commercial areas with stringent thermal requirements. The combination of material modernity and technical refinement positions it among premium solutions in the external door range.

The door achieves a Ud coefficient of 0.85 W/m²K, certified by ift Rosenheim, placing it in the premium energy performance category. This exceptional result is driven by the articulated 34 mm thermal break and the quadruple glazing system with triple-layer glass.

The profile is constructed from 3 mm aluminium with an articulated 34 mm thermal break. Aluminium provides exceptional durability, corrosion resistance, and maintains a flawless finish over time without warping or UV degradation—ideal for coastal or harsh climate exposure.

The door features quadruple glazing: 44.1 triplex / 5mm Satinato / 44.1 triplex—an advanced system combining four glass layers for maximum protection. The dual-triplex arrangement with 5 mm spacing delivers superior noise reduction and robust thermal insulation, addressing both heat loss and acoustic comfort.

The door comes in standard configurations up to 1100×2300 mm, with custom-build options available up to 1200×2500 mm for single-leaf installations. The profile system allows precise adaptation to existing masonry frames and can accommodate non-standard openings through dimensional adjustment or fixed sidelight combinations.

The door employs a multi-point sealing system with three EPDM gaskets strategically positioned to prevent air and moisture infiltration at all frame-to-leaf junctions. EPDM (synthetic rubber) maintains elasticity without UV or ozone degradation over 15–20 years, ensuring consistent sealing even under harsh weather conditions.

Installation requires certified professionals due to the system depth (92 mm total) and precision needed for sealing and levelling. The door adapts to standard 80 mm deep frames with extender options for wider openings. Masonry must be plumb and stable; after positioning, polyurethane foam and elastic sealant are applied to ensure final thermal and acoustic performance.
