The Lumon glazing types

Lumon Glazings are divided in two types: Lumon Glazing retractable and Lumon Glazing sliding.

Lumon Glazing Retractable

Retractable Lumon Glazing provides homeowners many advantages with the added flexibility of being able to open and close the balcony or terrace glazing panels as desired. A balcony and terrace glazing system with sliding and folding, hinged opening mechanism that scales according to the space, demands of the conditions, and customer needs.

The frameless glazing system is inward and outward opening and upper bearing, that is developed for worldwide use on balconies and terraces.
Unlike typical glass sliding doors, our frameless retractable glazing opens fully and folds tidily against an interior wall. Because they fold to the inside, our glass panes are easy to clean, use and maintain. They can also be secured to prevent them from moving with the wind.

With the retractable Lumon Glazing, we are able to provide glazings for all kind of projects around the world.

Lumon Glazing Sliding

We also need glazing products with sliding glass panes, sliding Lumon Glazing has been developed for this purpose. The sliding Lumon Glazing can be installed on top of a railing or as a room high glazing.

Sliding Lumon Glazing is low-bearing, as retractable Lumon Glazing is upper-bearing and need stable upper constructions. With these products, we can cover both terraces and balconies.


The Lumon Glazing Systems consist of two horizontal aluminium profiles attached to the balcony ceiling and the floor, parapet or a railing. Toughened (tempered) glasspanes are attached to the profiles through separate mechanisms allowing the panes to slide and to turn (Lumon Glazing Retractable), or just slide (Lumon Glazing Sliding).

The panes of the glazings are 6, 8, 10 or even 12mm toughened glass. The Table of Recommended Glass Pane Sizes shows the optimal glass thicknesses for each balcony. Toughened glass is not easily broken but in case it does break, it will crumble into small, blunt-edged fragments that do not pose a serious risk of injury. The glazing systems consist of glazings with upper and lower bearing. The plastic parts of the glazing are always dark grey.


Ventilation on the balcony is provided through the 2-3 mm gaps between the panes. The first pane can be locked in the ventilating position where it remains ajar. IMPORTANT! Ventilation is essential to prevent the condensation of moisture and to keep the balcony structures in good condition.


Lumon terrace glazing provides protection from wind and weather. However, due to necessary ventilation, the glazing is not fully airtight and, in certain conditions, rain or snow may enter the terrace.

Thermal insulation

The Lumon glazing systems consist of uninsulated aluminium profiles and single glass panes. A glazed terrace is not a warm space and its characteristics are not comparable to those of normal warm living spaces. Even after the terrace has been glazed, heat insulation of the building continues to be provided by the insulated wall, the windows facing the terrace and the terrace door.

Noise control

Lumon glazings reduce traffic noise by 8-16 dB. The results vary due to the thickness of the panes and the environmental conditions. A decrease of 10 dB corresponds to half as much audible noise.


Cleaning is very easy! Both the inner and outer surfaces of the panes can be washed safely from the inside of the balcony or terrace. Wash with a mild detergent.


Lumon glazings are custom made for each terrace or balcony. All materials and components related to the basic product (upper and lower profiles and the equipped glazing panes) are supplied by the factory, whereas accessories are delivered with the order.

Official regulations

Balcony glazing systems are subject to permission. The local official regulations relating to balcony glazing systems must be checked beforehand. Balcony glazing causes minimal changes to the visual appearance of the building as it is made of transparent, colourless glass and no vertical profiles are used.
