Sustainability Validations
At Lumon, research and validation are at the core of how we develop our products and solutions. We continuously collaborate with universities, research institutes, and industry experts to deepen our understanding of how balcony glazing impacts energy efficiency, building durability, occupant comfort, and sustainability.
Over the years, numerous independent studies, academic dissertations, and technical evaluations have examined the effects of balcony glazing in different climates, building types, and usage scenarios. These studies provide valuable insights into the role balcony glazing can play in reducing energy demand, extending the lifespan of building structures, improving acoustic comfort, and supporting more sustainable living environments.
Our product development is guided by this evidence-based approach. By combining real-world performance data with ongoing research, we are able to continuously refine our solutions and ensure they deliver measurable value for residents, building owners, and cities alike.
We believe innovation must be supported by facts. That is why we remain committed to validating our solutions through independent research and transparent reporting. This commitment helps us create products that contribute to more comfortable homes, longer-lasting buildings, and a more sustainable built environment.

Noise reduction – up to 28 dB sound insulation
Lumon Glazing significantly improves acoustic comfort and reduces the amount of external noise entering the home. Laboratory measurements have shown that Lumon Glazing can achieve sound insulation performance of up to 28 dB when the glazing system is installed using the most airtight configurations. The level of noise reduction experienced on a balcony depends on factors such as the building structure, balcony location, sealing solutions, and installation method. Nevertheless, a glazed balcony can substantially reduce disturbances caused by traffic, urban environments, and other external noise sources.
The results are based on testing commissioned by Lumon and conducted by SG-Bauakustik, as well as on Anttoni Kananen’s master’s thesis.

Protect balcony structures and the facade from weather exposure – longer service life and extended maintenance intervals
Lumon Glazing protects balcony structures from rain, snow, freeze–thaw cycles, and other weather-related stresses. This helps slow down structural deterioration and reduces the need for repairs. In addition, the glazing protects the facade adjacent to the balcony, as well as railings, seals, wooden elements, and other materials from exposure to moisture and UV radiation. According to research, balcony glazing alone can typically extend the service life of a balcony by 5–10 years. The overall impact on maintenance and repair intervals depends on factors such as the building’s age, structural design, and environmental conditions.

Fulfills energy requirements – Up to 16% heating energy savings
Balcony glazing can help reduce heating energy costs by adding thermal insulation and protection against extreme weather conditions, keeping homes warmer in winter and cooler in summer, reducing the need for heating and cooling systems. Research indicates that in Europe, balcony glazing typically reduces heating energy consumption by 2 to 16%.

According to researches, glazed balconies result in energy savings of 300 kWh on average compared to balconies without glazing.
