Introduction
Your Home Deserves More Than Standard
Imagine a home that actively cares for your comfort and household budget. A home where winter evenings are warm and cosy, whilst summer mornings remain pleasantly cool. This becomes possible when advanced technology meets genuine craftsmanship.
Have you ever wondered why some people enjoy surprisingly low heating bills whilst others watch costs rise with concern? Or why some homes maintain blissful silence despite the bustling street outside? The secret lies in window and door systems, which are far more than just barriers between interior and exterior. At BWS Technika Budowlana, as manufacturers of PVC windows, aluminium doors, external roller shutters and facades, we prove this is an intelligent investment in quality of life. Here, precisely selected parameters such as the U-value thermal transmittance translate into real savings in your wallet – often meaning heating cost reductions of up to 30% from the very first season.
We understand that the decision to replace windows, doors or install shutters raises concerns about costs and installation quality – it’s natural when investing in your family’s future. That’s why at BWS we don’t simply sell products. We offer a comprehensive solution: peace of mind flowing from the fact that as manufacturers, we control every stage of your aluminium and PVC joinery production. We give you confidence that our professional warm installation will unlock the full energy-saving potential of your investment. We open possibilities for silence through external roller shutters and facade blinds, warmth in conservatories, and bills that cease to be a source of stress.

Practical Knowledge About Window and Door Systems
Choosing window and door joinery is a decision for decades that raises many justified questions. In our blog, you'll find practical advice from BWS experts and our certified installation teams. Without marketing jargon, we explain key parameters of windows, doors, shutters and facades – from the U-value thermal transmittance to RC burglary resistance classes. We advise how to select insect screens for roof windows, when to choose PSK instead of HST doors, why facade blinds are better than internal ones, and how an aluminium pergola can replace a conservatory. We share knowledge from practitioners who work daily with the latest technologies from GEALAN, Yawal, Aliplast profiles. Stay current with trends, discover product innovations and make an informed decision.

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.
How much do PVC and aluminium windows cost? How do I get a quote?
Window prices depend on many factors: dimensions, chosen profile system, glazing package, colour and additional features such as anti-burglary hardware or trickle vents. PVC windows with GEALAN profiles cost from $320-460 for a standard reference window (1230×1480 mm), with professional installation from $420-580. Aluminium windowsrepresent an investment from $480-1000 per square metre, depending on the chosen profile system (Yawal, Aliplast). Popular anthracite foil increases the price by approximately 20% (single-sided) or 40% (double-sided). Triple glazing packages add an extra $70-80 to the cost. Contact us to receive a free, personalised quote tailored to your project – our technical advisor will help you choose the optimal solution.
What are the most important technical parameters for windows?
The most important parameter is the U-value (Uw), which determines the window’s energy efficiency – the lower the value, the greater the heating cost savings. Our energy-efficient PVC windows achieve Uw values from 0.6 to 0.9 W/(m²K), significantly exceeding Building Regulations requirements (Uw ≤ 1.6 W/m²K) and meeting Passivhaus standards. Aluminium windows in premium systems achieve even Uw = 0.5 W/(m²K). The second key parameter is sound insulation Rw – our systems provide 32-47 dB, guaranteeing effective protection against urban noise. Also important are security class RC2-RC3 according to EN 1627 standards and air permeability class 4. Ask our specialists about specific parameters for your home – we’ll find the optimal solution.
Can I receive grants for energy-efficient windows?
Yes, most of our windows and doors qualify for various government energy efficiency grants and green building incentives. Grant requirements typically include: windows with Uw coefficient no higher than 0.9 W/(m²K) and external doors with Uw ≤ 1.3 W/(m²K). Our GEALAN S8000 and S9000 systems easily meet these requirements. Grants can cover 20-40% of costs (depending on income brackets), with maximum amounts up to $15,000 for thermal modernisation. Additionally, tax credits are available allowing you to deduct costs from taxes. We offer free support in preparing documentation and submitting applications – benefit from our experience with grant programmes.
Do you offer professional window installation and how much does it cost?
We provide comprehensive, certified installation carried out by experienced teams following thermal bridge-free installation technology. Professional installation costs range from $220-480 per window (depending on size and complexity) or $60-120 per square metre. The price includes removal of old windows, installation of new ones with three-layer sealing, basic finishing work and cleanup. Standard window installation takes 3-6 hours. All our teams hold manufacturer certifications and extensive experience. Book a free technical survey – our specialist will provide a detailed quote and work schedule.
What is thermal bridge-free installation and is it worth the investment?
Thermal bridge-free installation is an advanced installation technology following industry best practices that eliminates thermal bridges around the window frame. We use three-layer sealing: inner vapour barrier, middle thermal insulation and outer wind barrier. Additionally, we use specialist tapes, low-expansion foam and structural anchors. Thermal bridge-free installation isn’t optional but our standard – it provides energy savings up to 15%, eliminates condensation and mould risks, and is a condition for maintaining manufacturer warranty. Our teams are trained in this technology – we carry out every installation according to the highest quality standards.
What warranty do you offer on windows, doors and installation?
We offer comprehensive warranty protection: GEALAN window and door profiles are covered by 5-7 year manufacturer warranty, glazing packages 5 years, MACO hardware up to 10 years, and installation with 5-year workmanship warranty. The warranty covers material defects, manufacturing faults and installation errors. It doesn’t cover mechanical damage occurring after handover or natural phenomena like external condensation. The claims process is straightforward – simply call or email us and our service team will arrange an inspection within 48 hours. As manufacturers, we provide after-sales service throughout the entire warranty period. For warranty enquiries, our customer service team is at your disposal.
