Aluminium exterior door L547-1 made to order

Aluminium entrance door L547-1 featuring exceptional thermal performance and quadruple glazing for superior energy efficiency. Articulated thermal break with triple EPDM sealing system ensures lasting weather protection and climate control.

The L547-1 exterior door represents a high-performance solution for residential and commercial entrances demanding superior thermal insulation. The 3 mm aluminium profile paired with a 34 mm articulated thermal break creates an efficient barrier against heat transfer, achieving a Ud coefficient of 0.85 W/m²K — certified by ift Rosenheim, the benchmark for European standards.

The system construction with a total depth of 92 mm and frame profile of 80 mm delivers structural stability and long-term durability. The 92 mm thick door leaf, combining 3 mm aluminium with internal insulation, ensures rigidity and resistance to mechanical stress. Sealing integrity is guaranteed through three strategically positioned EPDM gaskets, blocking air and water infiltration across all weather conditions.

The quadruple glazing — composed of 44.1 triplex / 5mm Satinato / 44.1 triplex — provides superior thermal insulation while allowing merit-worthy diffusion of natural light with subtle privacy effect. This four-layer configuration delivers noteworthy acoustic protection and impact resistance, essential for urban locations or noise-exposed areas.

Regarding design flexibility, the L547-1 fits standard dimensions up to 1100×2300 mm, with customisation available to 1200×2500 mm for single leaves, enabling adaptation to specific architectural requirements. The modular profiling system accommodates various opening configurations and hardware options, facilitating seamless integration into cohesive design concepts.

Recommended for energy-conscious residences, premium commercial properties and passive construction standards, the L547-1 complements solid wood flooring, natural stone tiles or underfloor heating systems, creating an entrance that is simultaneously modern, functional and refined.

The L547-1 door achieves a thermal coefficient (Ud) of 0.85 W/m²K, certified by ift Rosenheim, placing it in the premium insulation category. This performance results from quadruple glazing (44.1 triplex + 5mm satin + 44.1 triplex) combined with a 34 mm articulated thermal break in the profile, significantly reducing heat loss. For a standard residential property, such thermal efficiency translates to heating savings of 15–20% during the cold season compared to conventional doors.

The total system depth is 92 mm with a frame depth of 80 mm and a leaf thickness of 92 mm. This dimension is compatible with most modern standard frames in masonry (frames of 100–120 mm), but we recommend precise measurement before ordering to avoid additional work. If the existing frame is narrower (70–80 mm), installation is still possible with minor adjustments and appropriate threshold installation.

The L547-1 door features a triple sealing system with three EPDM gaskets (synthetic rubber), providing protection around the entire perimeter. These gaskets are specially dimensioned to adapt to variable pressure and seasonal changes, preventing water and air infiltration. The multi-point sealing system requires minimal maintenance—annual silicone treatment on the gaskets keeps it effective for 15+ years.

Standard maximum dimensions are 1100×2300 mm for double doors and 1200×2500 mm for single-leaf doors. All dimensions are available as custom orders with profile and glazing adjustments to your requirements—this is standard at kulttur.ro. We recommend a showroom consultation to establish exact dimensions and opening type (standard vs. pivot) relative to your space.

The L547-1 door is constructed from 3 mm aluminium (structural core) combined with quadruple glazing for maximum rigidity and durability. The finish depends on your choice—we offer standard paint, veneer, or laminate—and maintenance consists of periodic cleaning with water and neutral detergent, followed by drying with a soft cloth. For areas with severe exposure (salt spray, high pollution), we recommend biennial protective treatment with protective wax for aluminium.

The L547-1 door is designed to accommodate high-security hardware systems complying with European standards (RC2/RC3). The aluminium structure and quadruple glazing provide superior mechanical resistance to force. Upon order, we can integrate high-security cylinders, anti-burglary strikes, or electronic systems (card reader, push-pull button). Each security configuration is detailed before manufacture, with structural adaptations if needed.
