WDS 5S — Efficient Glazing Without Overpaying
The WDS 5S window system (60 mm) proves that a quality window doesn't have to be expensive. It's the ideal choice for those seeking a reliable solution for rental apartments, balcony glazing (terrazas), vacation homes, or coastal properties in Spain (Alicante, Malaga, Valencia).
Why Choose the 5S Series:
- Warmer than alternatives: Unlike most budget systems with 3 chambers, the WDS 5S profile has 5 air chambers. This provides a heat transfer coefficient of Uf = 1.3 W/m²K, which is 20% more efficient than standard narrow profiles.
- Spanish standard: The system is fully compatible with local roller shutter types (persianas) — both built-in (compacto) and surface-mounted, ensuring airtight sealing of the entire opening.
- Climate resistance: The glossy profile surface contains stabilizers resistant to intense UV rays and salty sea air. Windows don't yellow and require no special care.
- Aesthetics: Gray gasket (TPE) instead of black visually enlarges the light opening, making the window look light and neat.
A smart choice for home renovation where every centimeter of space matters (installation depth only 60 mm) and budget control is important, without compromising on airtightness and sound insulation.

FAQs
Frequently Asked Questions about WDS 5S
Can I install this window in an apartment?
Yes, it's an excellent option for apartments in warm climate zones (Costa Blanca, Costa del Sol, Andalusia). Thanks to 5 chambers, the WDS 5S system handles thermal insulation much better than regular 3-chamber windows. However, for regions with harsh winters or northern Spain, as well as for passive houses, we recommend considering 70 mm series and above for maximum energy savings.
The cheapest window — does that mean low quality?
No, the low price in this case is achieved not at the expense of plastic quality, but through design optimization. WDS 5S is the most affordable system in our range, but it's made from the same virgin PVC as premium series. It meets all European environmental and safety standards. Savings are achieved through lower material consumption (60 mm width) and classic design, making it the "people's choice" without losing functionality.
Can I install a soundproof glass unit in this profile?
Yes, the 60 mm installation depth allows installing glass units up to 32 mm thick. We can install acoustic laminated glass that will significantly reduce street noise, which is relevant for busy streets in Madrid or Barcelona.
Won't this profile turn yellow under the Spanish sun after a year?
No. WDS profiles are manufactured using quality additives (titanium dioxide) that ensure snow-white color throughout the entire service life, even under direct Mediterranean sunlight.
Is the WDS 5S system compatible with mosquito nets?
Absolutely. The profile configuration allows installing any type of mosquito net: frame, roller, or pleated, protecting your home from insects year-round.
How airtight are these windows? Will there be drafts?
The system has 2 circuits of modern sealing that reliably protect against drafts, dust, and moisture. With proper hardware adjustment, drafts are eliminated.
What's the difference between 5 chambers in this profile vs 3 chambers from competitors at the same 60 mm width?
5 chambers create more air layers inside the frame. Air is the best thermal insulator. Therefore, WDS 5S is warmer and quieter than standard 3-chamber systems of the same width, while the price remains affordable.
What is the service life of WDS 5S windows?
With proper use, WDS 5S windows last at least 40 years. The profile is resistant to UV radiation and temperature fluctuations, and quality hardware is designed for tens of thousands of opening cycles. We provide a 5-year warranty on the product and 2 years on installation work.
