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.

The price of your HST doors depends mainly on dimensions, selected parameters, and additional equipment. As a guideline, net costs (without installation) start from approximately $3,000 for a 3m × 2.25m (10ft × 7.4ft) construction and reach $5,500–$6,500 for larger 5m × 2.35m (16.4ft × 7.7ft) systems. Remember that investing in HST aluminum sliding doors is a choice for decades – their exceptional durability, proven energy efficiency, and real impact on property value make this a decision that pays off.

Key parameters to consider are the thermal transmittance coefficient Uw (for our systems 0.7–0.9 W/m²K), highest sealing classes for air (class 4), water (9A/E1350), and wind (C4/C5), plus acoustic insulation up to 47 dB. Modern HST aluminum doors with triple glazing achieve passive house standards.

The main difference lies in technology and comfort. HST doors operate on a “lift-and-slide” system – turning the handle gently lifts the panel, allowing effortless sliding. The PSK system requires force and a sequence of several movements. The key advantage of HST, however, is the possibility of perfectly flat, threshold-free passage, which is technically impossible with the PSK system.

Proper installation is an integral system element that guarantees full performance. Critical is the so-called “warm installation” on a special system base that supports weight up to 600 kg (1,320 lbs) and eliminates thermal bridges. Without professional installation, even the best doors with Uw = 0.8 W/m²K will lose their valuable insulation properties, potentially leading to operational problems and warranty loss.

Maintenance is extremely simple. Just wash the profiles with mild detergent 1–2 times yearly, dust the guide rails, and treat seals and hardware with dedicated care products. Powder-coated aluminum is virtually eternal – weather-resistant, low-maintenance, guaranteeing smooth operation and impeccable aesthetics for 30–40 years.

This is an investment for generations. With basic maintenance, HST aluminum sliding doors will operate flawlessly for 30, 40, or even more years. Aluminum doesn’t corrode, doesn’t fade under sunlight, and doesn’t deform under extreme temperatures. Unlike other materials, it maintains its properties and aesthetics throughout the entire product lifecycle.
