1. Introduction
Durability is one of the absolute strengths of the glass block. Unlike many transparent materials, the glass block:
- does not yellow
- does not deform
- does not oxidise
- does not corrode
- does not peel
- does not lose transparency
- does not require complex maintenance
It is a material that withstands time, weather conditions, thermal shocks, humidity, detergents, pollution, and daily use.
2. Intrinsic durability of the glass block
The glass block is made of pressed and sealed glass, with an internal chamber hermetically closed. This structure ensures:
2.1 Dimensional stability
Glass does not undergo:
- abnormal expansion
- deformation
- shrinkage
- structural movement
The wall remains stable over time.
2.2 Ageing resistance
The glass block is not subject to:
- yellowing
- colour fading
- dulling
- loss of brilliance
The surface remains unchanged even after decades.
2.3 Moisture resistance
The glass block is:
- waterproof
- non-porous
- immune to mould
- immune to fungi
- immune to efflorescence
3. Durability in outdoor environments
The glass block is ideal for exterior applications thanks to its resistance to:
3.1 UV rays
It does not fade, does not degrade, and does not lose transparency.
3.2 Frost and thaw
The sealed internal chamber prevents water ingress → no freezing expansion.
3.3 Salt exposure
Glass is immune to saline corrosion → perfect for coastal areas.
3.4 Atmospheric pollution
It does not react with:
- acid rain
- smog
- chemical agents present in the air
4. Durability in indoor environments
The glass block is ideal for:
- bathrooms
- kitchens
- swimming pools
- spas
- healthcare environments
- laboratories
- food-processing industries
Thanks to its:
- chemical resistance
- moisture resistance
- ease of cleaning
- aesthetic stability
5. Routine maintenance
Maintenance of the glass block is minimal.
5.1 Surface cleaning
Recommended products:
- neutral detergents
- glass cleaners
- water and soap
- soft cloths
- non-abrasive sponges
5.2 What to avoid
To preserve the surface:
- avoid abrasives
- avoid metal scouring pads
- avoid strong concentrated acids
- avoid strong concentrated bases
5.3 Satin surfaces
Satin surfaces may retain more dirt, but:
- they are easy to clean
- they do not degrade
- they do not lose colour
6. Extraordinary maintenance
Extraordinary maintenance concerns:
6.1 Mortar joints
Over time, joints may require:
- small repairs
- re-grouting
- resealing
6.2 Perimeter sealants
In exterior applications:
- periodically check sealants
- replace them if hardened or damaged
6.3 Reinforcement
Reinforcement is internal and requires no maintenance, but:
- it must be correctly installed
- it must be stainless steel
- it must comply with technical specifications
7. Structural durability of the wall
The durability of the wall depends on:
- quality of installation
- quality of mortar
- correct reinforcement
- correct expansion joints
- correct geometry
- correct supporting structure
A well-executed wall can last over 50 years without significant intervention.
8. Fundamental warning: what has been tested and what has NOT been tested. Durability tests refer exclusively to the glass block.
The tests certify:
- the resistance of the glass
- the stability of the internal chamber
- resistance to weather agents
- chemical resistance
- ageing resistance
No installation system has been certified.
The durability of the finished work depends on:
- mortar
- reinforcement
- joints
- sealants
- complementary materials
- installation quality
If an installer uses:
- unsuitable mortar
- non-resistant sealants
- non-compliant reinforcement
- incorrect joints
The declared performance CANNOT be guaranteed.
9. Technical responsibility notice (mandatory)
The performance values reported derive exclusively from official tests carried out on glass blocks.
Future Glass Block:
- does not certify installation systems
- does not guarantee the durability of the finished work
- cannot be responsible for installation carried out by third parties
- cannot guarantee performance if materials different from those used in the tests are employed
Final verification of the work must be carried out by:
- the designer
- site management
- the competent authority
