1. Introduction
Glass block is one of the most iconic and versatile materials in contemporary architecture.
It combines light, privacy, strength and design in a single construction element capable of transforming walls and surfaces into luminous, dynamic and timeless volumes.
Future Glass Block elevates this material to a higher level, offering a complete range of solutions for:
- architects
- designers
- construction companies
- interior designers
- general contractors
Our mission is clear: to be a reliable and competent technical partner for projects across Europe and South America.
2. How a glass block is made
A glass block is composed of two glass shells hermetically sealed together.
This structure ensures:
- mechanical stability
- thermal insulation
- acoustic insulation
- impact resistance
- long‑term durability
Surfaces can be:
- smooth
- satin
- wavy
- engraved
Available in clear, colored or special finishes.
3. Technical performance of glass block
3.1 Light transmission
Allows natural light to enter while maintaining privacy and visual comfort.
3.2 Thermal insulation
The internal air chamber reduces heat dispersion.
High‑performance thermal models are available.
3.3 Acoustic insulation
The mass of the glass and the internal cavity provide effective sound reduction.
3.4 Fire resistance
Glass is non‑combustible.
Models with fire resistance up to 120 minutes are available.
3.5 Impact and thermal shock resistance
Glass blocks withstand perpendicular impacts and temperature variations without deformation.
3.6 Durability
They do not yellow, deform or require extraordinary maintenance.

6. Compatible installation systems
d
Still the most widely used system on construction sites.
It includes:
- cement‑based mortar
- spacers
- reinforcement bars
- expansion joints
- perimeter anchoring
Ideal for:
- interior walls
- exterior walls
- curved walls
- large‑scale installations
It guarantees solidity, durability and a timeless aesthetic.
6.2 Modular systems
Solutions designed to simplify installation and reduce execution time:
- aluminium systems
- PVC systems
- solid wood systems
Some allow “dry installation”.
6.3 Prefabricated systems
Panels assembled in the workshop and delivered ready for installation.
7. Dimensional limits and design rules
To ensure safety and durability, a glass block wall must respect key principles:
- recommended maximum height
- recommended maximum length
- recommended maximum surface area
- mandatory expansion joints
- correct perimeter anchoring
- structural independence from load‑bearing elements
Glass block walls must always be considered self‑supporting, not structural.
8. Useful calculations for designers and contractors
8.1 Calculating the number of glass blocks
Based on wall dimensions and joint width.
8.2 Calculating final dimensions
Considering:
- joints
- lateral margins
- top and bottom margins
8.3 Calculating wall weight
Essential for evaluating:
- loads
- anchoring
- support structures
9. Maintenance and long‑term durability
Glass block requires minimal maintenance:
- clean with neutral detergents
- no painting
- no protective treatments
- resistant to weathering
It maintains its appearance and performance over time.
10. FAQ – Frequently Asked Questions

4. Can I build a fully glass wall?
Yes, using linear, curved and corner terminals.
5. What designs are available?
Wavy, Smooth, Iceberg and engraved finishes.
6. How do I calculate spacers?
Formula: D = (n + 1) × (m + 1).
7. What joint width is recommended?
10 mm for traditional installation.
8. Can I insert windows or doors?
Yes, with specific frames and proper spacing.
9. Is there a specific mortar?
Yes: GlassBond, for vertical structures.
10. What is the purpose of the expansion joint?
To prevent structural movements from stressing the glass.
11. Should reinforcement bars be welded?
No. They must remain free to avoid excessive rigidity.
12. Can I build large walls?
Yes, with correctly dimensioned expansion joints.
13. Does it resist extreme climates?
Yes, thanks to thermal shock testing.
14. Is ReadyBlock suitable for outdoor use?
Yes.
