Modern homes & NZEB

Aluminium exterior doors

An aluminium exterior door must combine safety, thermal insulation and design — especially when the facade is carefully considered and exposed to the elements. At Kulttur you find aluminium entrance doors for modern and NZEB homes, individually configured on size, colour, insulation and security details. Each door is made to order — from modern villas with oversized openings to complex commercial projects. Maximum security with strong anti-burglary protection and modern locking systems (GU and Winkhaus multi-point locks combined with fingerprint scanners).

Why choose an aluminium exterior door

Kulttur aluminium exterior doors are the ideal balance of durability, energy efficiency and aesthetic perfection. Aluminium is robust and solid — natural stability, exceptional structural resistance and long life.

Aluminium is also the most versatile material — fits ultra-modern and classic looks alike. Great flexibility allows infinite design possibilities, from tempered glass cutouts to made-to-order doors in any size, including oversized.

Superior thermal + integrated sound insulation

Kulttur aluminium exterior doors achieve an enhanced thermal coefficient up to 0.89 W/m²K, guaranteed by thermally-broken profile and thick door leaf — reduced heating costs + integrated sound insulation.

Anti-burglary protection

High structural resistance + GU & Winkhaus multi-point locking systems. On-demand upgrade to RC2 or RC3 class.

Detailed personalisation

Matte, glossy, textured colours or wood/concrete decors, tempered glass cutouts, special models. Smart access: fingerprint reader or keypad, ideal for smart homes.

Durability and easy maintenance

Electrostatic-field paint finish — rust-free, weather- and temperature-variation resistant. Thorough cleaning recommended at least once a year.

100% recyclable and eco-friendly aluminium

Aluminium is an eco-friendly, durable material — fully recyclable indefinitely without losing quality. Reduced carbon footprint.

Premium production quality

High-quality materials and cutting-edge technology for exceptional structural resistance and durability — doors keep their value even under heavy traffic.

For cleaner facades and contemporary expression

Aluminium exterior doors are known for structural rigidity, durability and real design freedom: large sizes, special colours, unconventional shapes. With thermally-broken profiles and triple low-E glass, they reach Ud values below 1 W/m²K — sufficient for NZEB and passive house projects. Maintenance is minimal — aluminium needs no periodic painting and holds its colour over time.

Performance for passive homes

Insulation, security, design — all in the project

Internorm aluminium exterior doors reach Ud values down to 0.62 W/m²K, with triple glazing and thermally-broken profiles. Available in RC2 and RC3 anti-burglary levels. Integrated handles, electronic cylinders, RAL colours and textured finishes.

FAQ

Frequently asked questions about aluminium entrance doors

For passive houses and NZEB, aluminium doors can be configured with Ud below 1 W/m²K. The exact value is calculated for each model and panel/glass combination.

In quality aluminium doors with stable profiles and correctly dimensioned panels, the risk of warping is minimal. Appropriate colour choice and professional installation help maintain stability over time.

An aluminium exterior door offers greater structural rigidity, superior durability and design freedom (large sizes, special colours), while PVC is more affordable but more limited in look and long-term stability.

For made-to-order aluminium entrance doors, allow several weeks for production and delivery. Installation is scheduled for a single day based on a clear timeline established at the quoting stage.

As standard, aluminium exterior doors are certified RC2, a class that resists manual attacks with basic tools. RC3 can be configured on request for enhanced protection — recommended for isolated properties or projects with special security requirements.
