Retractable (Cleanable) Guillotine Glass

Retractable (Cleanable) Guillotine Glass

Cleanable guillotine glass is an advanced movable glass system that, in addition to all the advantages of standard guillotine glass, lets the top panel tilt inward so the outer surface of the glass can be cleaned safely from inside. The panels slide vertically upward, operate with one hand thanks to a gas-piston balance mechanism and take no side space; the cleanable feature takes cleaning comfort to the highest level. Especially on upper floors, where outside access is difficult or dangerous, the ability to clean the outer surface from inside provides great convenience and safety. Made by GlobalTente, cleanable guillotine glass is an ideal solution for balcony, terrace and business façades for users who want both a panoramic view and practical cleaning.

In cleanable guillotine glass the panels move vertically up and down within side guide rails as in standard guillotine, and open with one hand via a gas-piston balance mechanism. The difference is that the top panel can tilt inward thanks to a special hinge system; when the panel tilts in, the outer glass surface that normally stays outside can be wiped easily from inside. This process is safe and fast and needs no outside equipment or dangerous access. After cleaning the panel is returned to the vertical position and the system continues normal operation. This mechanism combines the tightness and space-saving advantages of guillotine glass with cleaning comfort.

Technical Specifications

Use, Automation and Maintenance

• Cleaning from inside: the top panel tilts so the outer surface is wiped safely from inside.
• Upper-floor friendly: practical cleaning with no need for outside access.
• Takes no space: works vertically, ideal in narrow areas.
• One-hand use: effortless opening-closing with gas-piston balance.
• Full tightness: water-wind insulation with gasket and brush.

In standard guillotine glass, cleaning the outer glass surface requires outside access; on upper floors this is both difficult and dangerous, and often requires professional glass cleaning. Cleanable guillotine glass solves this problem at the root: the top panel tilts inward so the outer surface is cleaned from inside, safely and regularly. This is a great comfort and cost advantage especially for upper-floor homes and business façades. Keeping the glass always clean and clear preserves both the view and the façade aesthetics. If cleaning convenience is your priority, the cleanable model is far more practical than the standard guillotine.

In cleanable guillotine glass the factors determining safety and smooth use are the quality of the glass, the gas piston and the tilt-hinge mechanism. The panels are made from 8-10 mm tempered glass; tempered glass is impact-resistant and breaks into small, non-sharp pieces. Quality hinges and locks of the tilt mechanism ensure the panel tilts inward safely and closes watertight again. The gas-piston balance mechanism keeps the panel at the desired height. EPDM gaskets and brushes maintain water-wind tightness. With quality components, GlobalTente ensures both cleaning comfort and long-lasting, watertight operation.

• Easy and safe cleaning: the outer surface is wiped from inside even on upper floors.
• Season extension: balcony and façade usable in four seasons.
• View preserved: the glass stays always clean and clear.
• Narrow-area friendly: needs no side opening.
• Hygienic: with easy regular cleaning the façade always looks well-kept.

• Upper-floor residential balconies and terraces
• High-rise business and office façades

Cleanable guillotine glass is ideal for users who live or run a business especially on upper floors and want to clean the outer glass surface safely and practically. On high façades where outside access is difficult, the cleanable feature removes the cost and risk of cleaning. If cleaning convenience is not the priority, standard guillotine glass is a more economical alternative; if there is a wide flat opening, sliding glass is considered. All movable glass solutions are part of the glass systems family and can be integrated with a pergola or glass roof above.

Cleanable guillotine glass and standard guillotine glass share the same vertical working principle, gas-piston balance and tightness advantage. The only difference is that in the cleanable model the top panel tilts inward so the outer surface can be cleaned from inside. The standard model is more economical and enough for the ground floor or façades with easy outside access. The cleanable model stands out on upper floors and where outside access is difficult, with its cleaning comfort and safety. The height of your façade and the situation of outside access determine which model is more suitable.

Cleanable guillotine glass installation consists of survey and measurement, production to the façade dimensions and precise installation. The most critical issues are levelling the side rails to the millimetre, the correct slope for water drainage, seal-brush integrity and correct adjustment of the tilt mechanism. The hinge and lock are adjusted precisely so the top panel tilts smoothly and closes watertight again. Correct calibration of the gas-piston balance mechanism ensures the panels operate with one hand. Experienced installation guarantees the cleanable feature works trouble-free for years.

The biggest advantage of cleanable guillotine glass is that its maintenance and cleaning are easy. The top panel tilts inward so both the inner and outer glass surfaces are cleaned from inside, safely and regularly; this removes the cost of professional glass cleaning on upper floors. Clearing dust from the side rails and wheels once or twice a year and checking the seals is recommended. The tilt hinges should be kept clean and working properly. With this simple routine cleanable guillotine glass stays both clean and trouble-free.

The price of cleanable guillotine glass varies by total façade dimensions, number of panels, glass type (single/double) and profile and mechanism quality. The cleanable feature, with its extra hinge and lock mechanism, raises the cost a little compared to standard guillotine; but especially on upper floors it more than justifies this difference in terms of cleaning cost and safety in the long run. The double-glazing option increases insulation. Choosing a quality mechanism ensures the cleanable feature works trouble-free for years. The net price is given after a free survey.

As single glazing, cleanable guillotine glass provides a wind and dust barrier; if thermal and acoustic insulation is your priority, the double-glazing option makes a clear difference. Double glazing reduces heat transfer thanks to the gas gap between the two panes, lowers the risk of condensation and cuts outside noise. This means savings on heating in winter and cooling in summer. The cleanable feature, by keeping the glass always clean, also preserves light transmission and therefore the brightness of the space; clean glass means more natural light.

In cleanable guillotine glass safety is ensured with both tempered glass and the quality design of the tilt mechanism. Tempered glass withstands impact and breaks into low-injury pieces. The tilt mechanism ensures the panel is held safely during cleaning and does not drop accidentally. The most important safety advantage is that it removes the need to lean out of the window or use dangerous access to clean the outer glass on upper floors. In daily use, cleanable guillotine offers both a safe and a hygienic façade; the glass stays always clean and clear.

Cleanable guillotine glass puts the glass in the foreground with a slim profile choice and makes the space look larger; frameless solutions give the sense of an almost invisible barrier. The profile colour is chosen from the RAL catalogue to match the building's joinery, pergola or façade system; anthracite, matte black and white are the most preferred. With clear, smoked or frosted glass, the level of privacy can be adjusted. The cleanable feature, by keeping the glass always clean, guarantees the chosen colour and transparency look like new for years; so the façade stays both functional and aesthetic.

Cleanable guillotine glass comes standard with an aluminium profile, tempered glass panels, a gas-piston balance mechanism, an inward-tilt system and an EPDM gasket-brush. Options: double glazing; smoked or frosted glass; slim-frame/frameless design; a lock system; special RAL colour profile; integration with a pergola or glass roof above. These options allow cleanable guillotine glass to be turned into an insulated, fully enclosed outdoor-room solution as needed. Equipment selection is determined during the survey according to the height and intended use of the façade.

Cleanable guillotine glass answers different needs with the same façade throughout four seasons. In spring and autumn the panels are held at half height for both fresh air and wind protection. In summer the panels slide fully up to open the façade; in the cool evening they come down to keep insects and wind out. In winter, when the system is fully closed and combined with a heater, a comfortable seating area is created even when it is cold outside. The extra benefit of the cleanable feature is that the glass is easily cleaned at season changes and always stays clear; this prevents seasonal dirt such as rain, dust and pollen from leaving marks on the façade. So the glass preserves both the view and brightness at the highest level all year.

At home, cleanable guillotine glass creates great value especially in high-rise apartments; residents can keep the glass always clean without hiring a professional service or dangerously leaning out of the window. On the commercial side, the cleanable feature means regular, low-cost cleaning for upper-floor office and business façades; keeping the shop window and façade glass always clear makes the space look professional and well-kept. In cafés and restaurants, since the cleanliness of the façade glass directly affects customer perception, cleanable guillotine is a practical, image-preserving investment for businesses. Both at home and in commerce, the cleanable feature keeps the façade well-kept for years.
