FAQ Balcony Glazing

How much does a balcony glazing cost?
The price of balcony glazing depends entirely on the balcony to be glazed, including its size and structural requirements, as well as the method of installation.

What to do if the balcony glazing does not open?
If the first glass does not open, the gap between the first and second glass must be widened by pushing the second glass in the opposite direction. The opening should be wider, approx. 3 mm, so that the glass can be turned to the side. You can find the opening instructions in the user guides in pdf format here
How tight is the glazed balcony? Is a balcony glazing completely sealed?
A Lumon balcony glazing system protects the balcony specifically from wind and storms. The system is not completely sealed, as the balcony also needs ventilation but provides sufficient protection against rain and dirt, which means that you don’t have to wipe your furniture and interior so often.

In rainy and windy weather conditions, small amounts of water can enter the balcony or terrace. Keep in mind that the balcony is still a semi-outdoor space, even if the glazing provides very good protection.
How should a glazed balcony be ventilated? Does the glazed terrace need to be ventilated?
1-3 mm wide openings between the glass-panes are sufficient for ventilation of the balcony. Even between the roof and the upper profile, a gap can sometimes appear. This is due to height differences in the ceiling.
If you want more effective ventilation, you can open the first glass to the ventilation position.
Note! The balcony must not be sealed too much. Proper ventilation ensures that structures dry out and remain in good condition. If you want to reduce the opening in question, order transparent PVC seals from your Lumon office or online store.

A glazed balcony is a ventilated space because concrete and construction need to be aired in order not to become damp and spoil. With good ventilation, the structures dry out and remain in good condition.

The gaps between the glasses are 1-3 mm so that the balcony or patio can have good ventilation.

NOTE! Do not leave children or pets on the balcony without supervision, with the glazing in the ventilation position. Due to the risk of falling, the glazing is child and pet safe only when completely closed.
What sounds or rattles do you hear from the balcony glasses?
Balcony glazing reacts to temperature changes like any other aluminum or glass product. The possible frosting of the glazing is due to the expansion of the aluminum profiles when they react to temperature changes. This possible expansion has been taken into account in the design of the system and its attachments. Crashing does not affect safety or operation.
Is it dangerous if the glass pane is bent?
Tempered glass is flexible and can therefore bend slightly. In the normal case, a deflection of 3 mm/m is allowed, but on a very windy day, the glass panes can bend slightly more. Due to the flexibility of tempered glass, this type of glass can withstand impacts better than normal glass.
Why frameless?
Frameless balcony glazing makes your balcony feel more spacious and airy. You can also enjoy a panoramic view of your surroundings without any frames or vertical profiles obscuring the view.
In addition, the facade gets a stylish look that does not change the style of the building significantly. At the same time, space is left for architects and developers to create new unique facades, as the glass can be obtained in different colors and textures.
