Opening type
Casement, tilt-and-turn, sliding, folding or fixed: the right typology follows available space, frequency of use, weathertightness, dimensions and architectural intent.
Technical resource / aluminium systems
What determines the right aluminium-system selection
A practical guide to the decisions behind aluminium windows, doors and façades, from opening type and thermal performance to glazing, security, finish and maintenance.
TECHNIKAL
Selection before specification
There is no “best” window or door without defined requirements.
The right choice does not begin with a product code. It begins with the building, climate, use, dimensions and interfaces. System, glazing, hardware, finish and installation are then selected as one integrated solution.
Explore the system rangeThermal performance & Uw
Uw applies to the complete window or door, including frame, glazing, spacer and geometry. It is not the value of one material and must be calculated for the actual dimensions and build-up.
Glazing
Double or triple glazing, low-emissivity coatings, solar control, acoustic performance and safety are combined according to orientation, climate, use and regulatory requirements.
Air & water tightness
Performance depends on the system, gaskets, drainage, fabrication and, critically, the connection between the frame and structural opening.
Security
Profiles, hardware, locking points, glazing and anchoring should be treated as one strategy matched to the actual risk of the space.
Surface protection
Powder coating, anodizing and specialist finishes are selected according to exposure, colour, texture, design life and cleaning requirements.
Window replacement
The survey must consider the existing opening, seals, sills, shutters, shading, electrical routes and making good, not only clear dimensions.
Cleaning & maintenance
Mild detergent, clean water and a soft cloth are the safe basis. Abrasives and strong chemicals should be avoided, while hardware, drains and seals require periodic checks.
Five questions first
The right questions before choosing a system.
The answers create a clear performance brief and enable a meaningful comparison of technical solutions.
- 01Where is the project and how exposed is it to wind, rain or a marine environment?
- 02What are the thermal, solar-control, acoustic and security requirements?
- 03Which dimensions, weights and operating methods are genuinely needed?
- 04How does the system connect to waterproofing, insulation, shading and finishes?
- 05What is the plan for access, cleaning, maintenance and eventual replacement?
Project-specific verification
Performance is demonstrated for the specific configuration.
Technical data, calculations and certificates must be assessed against actual dimensions, materials, opening method and installation. This guide informs the discussion; it does not replace project-specific engineering.
