Why Choose Aluminium Windows?

5 Key Advantages of Aluminium Windows

Do you know why aluminium windows have become the foundation of modern, conscious architecture? It's a choice where project coherence and uncompromising quality are non-negotiable. As architects' preferred material, aluminium transforms spaces through impressive panoramic glazing, guarantees stable energy performance for decades, and captivates with minimalist aesthetics. It's a long-term investment in excellence that combines unlimited technical possibilities with complete design freedom, offering solutions unavailable in any other material.

Panoramic Views

Large-format panoramic windows without any limitations

Do you dream of opening your living room to the garden through an almost completely glazed wall? Aluminium windows, thanks to exceptional profile rigidity, enable the creation of panoramic glazing with impressive dimensions, significantly exceeding the capabilities of uPVC or timber. Their structural strength allows safe installation of massive glass panes weighing up to 240 kg (530 lbs), creating expansive, uniform surfaces without the need for additional mullions. This is the key to achieving the trendy "glass wall" effect and maximizing natural light in your interiors.

Resilience

50+ years lifespan with zero maintenance costs

Imagine windows that maintain their flawless appearance and full functionality for over half a century. Aluminium windows are an investment for generations with an estimated lifespan of 50-75 years, while standard uPVC windows last an average of 15-25 years. Most importantly, throughout this entire period, they require no maintenance work – no painting or treatment, unlike timber windows. This represents real time and money savings, making aluminium the most economical and maintenance-free choice in the long term.

Passive House Standards

U-value from 0.5 W/(m²K) – highest passive house standard

True luxury means warmth and tranquility in your own home. Modern, thermally efficient aluminium windows achieve remarkable thermal transmittance values (U-value) as low as 0.5 W/(m²K), easily meeting the strictest 2021 building regulations (Uw ≤ 0.9 W/(m²K)). The advanced Yawal and Aliplast systems we select for our range feature certified parameters for passive house construction. These energy-efficient solutions guarantee real heating cost savings and unmatched thermal comfort, combining this with construction capabilities unavailable in other materials.

Personalization

Palette of over 200 RAL colors that maintain their shade for decades

Is design important to you? Aluminium offers almost unlimited creative freedom – over 200 colors from the RAL palette compared to a few dozen options in uPVC or timber. Thanks to advanced anodizing and powder coating technologies, the color is extremely durable and UV-resistant, without fading or changing shade over decades. This complete personalization allows perfect matching of windows to the architect's vision, guaranteeing aesthetic consistency throughout the entire service life.

Slim Profiles

Profiles from 37 mm – design that lets in more natural light

In modern architecture, less is more. Slim, almost invisible aluminium profiles with widths of just 37-77 mm represent the quintessence of minimalism and a key trend for 2025. They maximize the glass surface area, flooding interiors with natural light and creating an uninterrupted panoramic effect. While other materials require wider, more massive frames, aluminium enables the realization of "disappearing" windows that enhance the sense of space and lightness.

Profile Systems for Aluminium Windows

Profile systems – the foundation of your project

Every architectural project is unique and presents different requirements. Our role as experts involves precise selection of systems that perfectly meet your needs – from minimalist, slim glazing to certified solutions for passive houses. We work with leading brands Yawal and Aliplast because their profile systems guarantee the highest, documented technical parameters. They enable us to realize your project requirements without any compromises. Below we present the systems we select for the specific needs of each investment.

Personalization of Aluminium Windows to Meet Your Needs

We treat each window as a harmonized ecosystem of components where every element has its purpose. Our role as experts involves selecting Yawal and Aliplast profile systems, glass packages, Winkhaus hardware, and warm edge spacers so they work together as one reliable architectural system. Every component – from automation to smart home solutions – fulfills a specific function in implementing a coherent project, with guaranteed long-term reliability and perfect operation.

Frequently Asked Questions

At BWS Technika Budowlana, we know that choosing windows and doors is a decision for years. That's why instead of marketing, we offer you our knowledge and experience. In this section, you'll find clear, professional answers to the most common questions about energy-efficient solutions, certificates, warm installation, and key technical parameters.

Definitely yes. The myth of “cold aluminium” is a relic of the past. Contemporary aluminium windows, thanks to advanced multi-chamber profile construction, match the parameters of the best systems on the market. The key element is special thermal breaks made of glass fiber reinforced polyamide that effectively interrupt thermal bridges. As a result, the best systems achieve thermal transmittance coefficient Uw ≤ 0.8 W/(m²K), qualifying them for rigorous passive house construction and guaranteeing excellent insulation.

Aluminium windows are a lifetime investment, characterized by exceptional durability exceeding 50 years of operation while maintaining original parameters. Aluminium is almost completely resistant to weather conditions, corrosion, and UV radiation. Thanks to its low thermal expansion coefficient, it doesn’t deform under temperature influence, guaranteeing perfect sealing for decades. Unlike other materials, aluminium doesn’t yellow, crack, or require renovation.

Aluminium provides unlimited aesthetic personalization possibilities, allowing perfect adaptation to any architectural concept. Available is the full RAL palette with hundreds of colors, from classic to avant-garde. Finishes include smooth powder coatings, elegant anodizing with unique metallic appearance, modern structural coatings, and photorealistic wood imitations. Moreover, a dual-color option is possible – different color inside and outside the building.

In modern architecture, where design and large glazing matter, aluminium has an undeniable advantage. Its higher rigidity allows creation of large-format structures using minimal, elegant profiles, maximizing glass surface. While uPVC requires thicker frames and has greater dimensional limitations, aluminium enables realization of panoramic glass walls and non-standard shapes. In terms of thermal parameters, modern aluminium systems match the best uPVC solutions while offering significantly greater design freedom and durability.

For energy-efficient and passive houses, aluminium windows with advanced multi-chamber profiles equipped with wide thermal breaks and additional insulation inserts are dedicated. It’s crucial that the thermal transmittance coefficient for the entire window (Uw) is as low as possible – for energy-efficient construction Uw ≤ 0.9 W/(m²K) is required, and for passive Uw ≤ 0.8 W/(m²K).. Equally important is the so-called “warm installation” using specialist tapes, which guarantees achieving catalog parameters in practice.

Aluminium windows are virtually maintenance-free, which is one of their main advantages. Their care is limited to regular cleaning of frames with a soft cloth with water and neutral detergent. Avoid abrasive agents. The key element is annual, simple hardware maintenance – just clean and lubricate moving parts with special oil, ensuring smooth operation for decades. Seals should be occasionally treated with silicone-based agent to maintain elasticity. That’s all – no painting or complicated renovations.
