Design and comfort
The Tandem Curtain is another enclosure option which combines design and comfort. In this case, the panels do not fold, but slide smoothly along the stainless steel rails. By pulling just one panel, all glass panels will slide along for opening or closing. This way, it is possible to have a perfect panoramic view, and it is suitable for those terraces where you wish to make the best possible use of them.
The Tandem Series is an efficient system that offers multiple possibilities for businesses as well as for homes. It is possible to install up to 10 panels with a maximum opening of 80% and the system counts on stainless steel rails which guarantee durability and is optimised for water evacuation. Additionally, this is the option for those spaces where the panel weight should be supported by lower guides.

Si es Acristalia, es calidad


The tempered glass used in the glass curtain systems has obtained the CE marking with the maximum classification for all its range of products following the UNE 12150-1. The glass provides the system with all the mechanical and safety properties, offering high shock resistance, protection under sudden changes of temperature and safer response in case of breakages, as they do not produce sharp-pointed fragments. Aluminium used in our systems is composed of alloys, specially studied, to offer high mechanical performance, shock resistance, great durability and easy cleaning.


They completely fulfil the European regulations UNE-EN 755-2 and UNE-EN 755-9. Not all manufacturers can stamp the international quality label Qualicoat on their lacquered products. The anodized options of our catalogue follow all guidelines marked by the quality label Qualanod such as UNE-EN ISO 2360, EN 12373-1, UNE-EN 12373-4, EN 12373-7.


As new as the first day


A correct use and regular maintenance guarantee the very best performance and a long service life.


Closing system with a key: The use is similar to that of any door with handle and key.



The PVC water seals used between glass must not be cleaned with abrasive cleaning products, because the contact with those together with the exposition to sun rays can deteriorate them.

Use cleaning products for this purpose to clean the glass. Do not use utensils that could provoke damages or scratches. In case of special or coated glass a special care must be taken. Do not dry clean. The cleanliness of the glass is extremely easy in our glass curtain. In the closing position, you will access the inner side of the glass; and in the open position, you will access the outer side of the system.

Use cloths and dusters for cleaning the profiles. Do not use scrapping tools or utensils that may cause them damages. Use neutral non-abrasive products, whatever the profile finish.

You can download all necessary manuals for the installation, maintenance and cleaning of the Tandem Series of Tandem Curtain.
