Tempered glass railings: safety and modern design
Tempered glass railings represent the most modern and elegant solution to ensure safety on balconies, staircases, terraces and pool areas. At Caixilharia Blanco, we are specialists in the design, fabrication and installation of glass railings in Alcobaça and all mainland Portugal, with more than 500 certified installations that rigorously comply with Portuguese safety regulations.
WHY CHOOSE US
Why choose tempered glass railings?
Tempered glass is a revolutionary material that combines extreme safety with impeccable aesthetics. Through a specialised thermal process, ordinary glass is transformed into a material 5 times more resistant, capable of withstanding significant impacts without breaking. In the unlikely event of breakage, tempered glass shatters into small granular pieces with no sharp edges, completely minimising the risk of serious injury.
Glass railings are not just an aesthetic choice, they are an investment in safety, durability and property value. Real estate industry studies show that properties with quality glass railings can increase their market value by between 5% and 10%, while also significantly reducing time to sale.

MATERIAL
Types of glass
Clear glass
Crystal-clear glass with maximum transparency. Ideal for panoramic views without obstructions. Allows full passage of natural light. The most popular option for balconies with sea or mountain views.
Light transmission >90% · Available in 10 and 12mm · Optimal for exteriors and interiors
Satin / translucent glass
Satin treatment that provides privacy while maintaining brightness. Ideal for balconies in dense urban areas or interior railings. Discreet elegance.

100% customisable design · Permanent printing on the glass · UV and fade resistant
Laminated glass
Made up of two glass panes bonded by a PVB (polyvinyl butyral) interlayer. In the event of breakage, fragments remain adhered to the inner film without falling, eliminating the risk of glass falling. Significantly improves acoustic insulation compared to monolithic glass.
Superior passive safety · Fragment retention · Improved acoustic insulation
Laminated+tempered glass (VSG)
The best option for safety and strength. Combines the properties of tempered glass —5× stronger than standard glass— with those of laminated glass —total fragment retention in case of breakage—. VSG certified. The perfect combination for each client's needs: maximum protection without sacrificing transparency or design.
Maximum VSG-certified safety · Ideal for high-risk areas · The choice for the most demanding projects

- Rinse abundantly with clean water
- Dry with synthetic chamois or glass cleaner
- Extra shine: ammonia-free glass cleaner
NEVER use: abrasive products, metal scourers, concentrated ammonia or scrapers.

Regular cleaning:
- Neutral detergent: Fairy, diluted Skip
- Glass cleaner: Cif Vidrão, Mr. Muscle
- Cloths: Vileda microfibre, synthetic chamois

Frequently Asked Questions
Everything you need to know about glass railings
We answer the most frequently asked questions about our tempered glass railings.
Absolutely yes. Tempered glass is 5 times more resistant than regular glass thanks to a thermal process that creates balanced internal tensions. In case of breakage (extremely rare), it shatters into small granular pieces with no sharp edges, completely minimising the risk of serious injury.
All our glass complies with the EN 12150 standard and has mandatory CE marking. In addition, the railings are sized to withstand 300kg/m of horizontal load, greatly exceeding Portuguese regulatory requirements.
Yes, 100% guaranteed compliance. All our railings respect the Regulamento Geral das Edificações Urbanas (RGEU) of Portugal and applicable European standards. This includes: minimum height of 1.10m, mandatory use of certified safety glass, structural resistance of 300kg/m, and maximum distance of 11cm to the floor.
Each installation includes CE certificates of the glass, material technical data sheets, structural calculations validated by an engineer, and declaration of conformity from the installer.
Extremely simple maintenance. Only periodic cleaning with water and neutral detergent every 2-3 months. For extra shine, you can use ammonia-free glass cleaner. We recommend an annual visual inspection of the fixings.
In areas with high marine exposure, we advise applying water-repellent treatment every 2-3 years. Unlike iron railings that require periodic repainting or costly anti-corrosion treatments, glass maintains its properties with minimal maintenance.
Yes, it is a perfect application. Glass railings are ideal for pool areas: they provide full safety without obstructing the view, tempered glass is completely resistant to chemicals (chlorine, salt), does not suffer corrosion, and is extremely easy to clean.
For pools, we recommend systems with 316 stainless steel (marine grade) or high-resistance lacquered aluminium, combined with 12mm tempered glass. Perfect for infinity pools, elevated pools, or to ensure child safety without compromising the aesthetics of the garden.
The complete process from initial contact to final installation includes:
- Technical visit: Usually in 2-3 days after contact (duration 1-2 hours)
- Project and quote: 3-5 working days
- Custom fabrication: 2-3 weeks (CNC cutting, thermal tempering and preparation)
- Professional installation: 1-2 days depending on project size
In total, from quote approval to completed installation, the typical lead time is 3-4 weeks. A standard 6-8 linear metre balcony is carried out in 1 working day.
10mm thickness: Suitable for most standard residential applications (balconies, interior staircases, terraces). Fully complies with regulations, offers excellent value for money.
12mm thickness: Recommended for more demanding applications (large spans, heights above 1.20m, high wind exposure, pools, commercial areas). Provides greater robustness and is mandatory in self-supporting systems without profiles.
Consult the price difference with our team. Our technicians evaluate each project and recommend the optimal thickness.
Yes, even more so than metal alternatives. Tempered glass is completely inert to sea salt, does not suffer corrosion or degradation from exposure to a saline environment. A huge advantage over iron railings (which oxidise quickly).
For coastal areas such as Nazaré, we especially recommend systems with lacquered aluminium profiles with special marine treatment, or 316 stainless steel systems (marine grade superior to standard 304 stainless steel).
We have hundreds of installations on the seafront with more than 10 years without any corrosion issues.
Yes, full 5-year warranty. Our warranty covers:
- Tempered glass: Against non-accidental breakage, manufacturing defects, loss of transparency
- Aluminium/stainless steel profiles: Against corrosion, deformation, lacquer detachment
- Fixings and hardware: Against breakage, corrosion, loosening
- Installation: Against assembly defects, incorrect levelling, leaks
All our installations include after-sales service and technical assistance throughout the product's service life.
