The Lumon SmartProtect renovation concept
Extend the service life of old balconies cost-effectively, with style and functionality without heavy renovation.
Balconies built to last — Now reaching their limits
Apartment buildings built in the 1960s–80s in many European countries are reaching the final third of their technical lifespan. The concrete used in these buildings often no longer meets today’s durability requirements. Balconies are particularly exposed to weather, moisture, freezing, and temperature fluctuations. A full renovation can be expensive and difficult to implement, and often a more feasible option is to protect the structures and extend their lifespan.
Timely condition assessments and preventive maintenance are key to avoiding costly damage. Research shows that early protective actions such as balcony glazing can slow down structural deterioration and extend service life by 15–20 years.
Smart protection today reduces major renovation tomorrow
Lumon SmartProtect is a smart, preventive way to extend the lifespan of aging balconies — cost-effectively, with style and functionality, and without heavy renovation.
Balcony glazing shields concrete surfaces from moisture, UV radiation, and harsh weather, helping to slow down wear and corrosion. This protection can extend the service life of balconies, reduce maintenance costs, and delay major renovations — all while preserving the building’s original architecture.
- Extends the service life of old balconies cost-effectively, with style and functionality without heavy renovation.
- Reduces the frequency and cost of heavy facade and balcony renovations.
- Adds architectural refinement and modern usability.
With Lumon SmartProtect, housing companies can take control of building maintenance instead of reacting to damage.
Choosing Lumon SmartProtect is not just nice to have — it’s a wise investment in the longevity, value, and comfort of your property.
1. Protect more. Renovate less.
Balcony glazing is more than a visual upgrade — it’s preventive protection for the building’s structure. By shielding balcony edges and surfaces from rain, snow, frost, and UV radiation, glazing significantly slows down structural decay. It helps prevent carbonation and corrosion in concrete and reinforcement, protecting the most vulnerable slab edges from moisture damage. The result is a more durable balcony with fewer costly repairs. Shield the structure, cut the risk.
2. Make balcony structure protection part of your plan
Including balcony glazing as part of a housing company’s long-term plan brings measurable benefits. Preventive protection extends balcony lifespan, reduces the need for major renovations, and makes maintenance cycles smoother and easier to manage. With unified planning, housing companies gain predictable costs, steadier budgets, and fewer surprises. Less frequent renovations and better energy performance support sustainability goals, while consistent facades and durable materials help maintain both architectural integrity and property value over time.
3. Predictable maintenance, steadier budgets
Early balcony glazing is a smart way to protect structures and prevent costly surprises. Planned protection keeps maintenance smooth and predictable, helping housing companies avoid urgent repairs and better manage budgets.
By extending the balcony’s service life, glazing helps delay major renovation expenses, protecting both the building and its value. With a typical payback time of 6–7 years compared to renovation costs, it’s an investment that quickly proves its worth.
4. Keep the character or discover a new one
Lumon’s era-sensitive balcony glazing design either honors the building’s original character or introduces a fresh, unified look. It refines and protects facades, enhancing architectural integrity while respecting heritage aesthetics and adding a modern touch.
Many apartment buildings from the 1970s and later feature minimalist facades that have lost their identity over time — glazing restores visual harmony and life. With tinted or screen-printed glass, balconies gain a subtle elegance that boosts curb appeal, resident satisfaction, and property value in a cost-effective way.
5. More room for life
Balcony glazing transforms outdoor spaces into versatile, semi-indoor areas that can be enjoyed for most of the year. It adds functional living space for relaxation, storage, or hobbies — even during cooler seasons. By protecting from wind, rain, and noise, glazing improves comfort and livability, while the added light and connection to the outdoors enhance wellbeing and apartment value. The result: more usable space, greater satisfaction, and better energy efficiency year-round.
6. Safety, built-in
Lumon glazing and railing systems are designed, tested, and maintained for long-term reliability. Each solution is custom-engineered for its building, verified to meet European safety standards, and supported by scheduled maintenance and long-term spare-parts availability.
From design to installation and beyond, Lumon ensures safety, performance, and peace of mind for decades.
7. Energy that goes further
Balcony glazing creates a protective buffer zone between exterior and interior spaces, helping reduce heat loss and energy demand. By adding thermal insulation and shielding against extreme weather, glazing keeps homes warmer in winter and cooler in summer, lowering the need for heating and cooling. Studies across Europe show energy savings between 2% and 20%, with an average of around 300 kWh saved per balcony each year compared to unglazed structures.
8. Less noise, more peace
Urban living brings constant background noise — from traffic and trains to nearby construction. Balcony glazing with high-quality materials reduces outdoor noise by up to 20 decibels, effectively halving the perceived sound level. This transforms a noisy balcony into a comfortable outdoor living space, even in busy environments, and also reduces the amount of noise entering indoor areas. The result is greater comfort, higher property value, and a more attractive offering in markets where quiet living matters.
Three ways to carry out a balcony renovation with Lumon SmartProtect:
Every Lumon SmartProtect solution is carefully engineered to enhance both performance and design. It combines a discreet, timeless look that fits naturally into existing facades with the functional benefits of improved comfort, energy efficiency, and safety.
•After this, the balcony is protected with Lumon balcony glazing, which extends the balcony’s service life by 10–15 years.
•Suitable for sites where wear has begun but the structures are still mostly in good condition.
•The old railing is removed and replaced with Lumon’s light and modern railing solution together with balcony glazing.
•This option refurbishes the balcony structurally while also updating the facade to a modern look.
•The service life is extended by up to 25 years.
•A new balcony slab is constructed by the contractor, and the balcony is finished with Lumon railings and glazing.
•Provides a completely new balcony facade and a service life of over 60 years.
•Suitable for sites where the structures have reached the end of their life cycle or where a significant architectural upgrade is desired.
No one has come up with such a completely correct proposal for a renovation that manages both the climatic, acoustic and thermal aspects, but at the same time also wraps it in a form that supports the social cohesion of the building.
