A wall’s thermal performance can’t be reduced to a single R-value.
It depends on three key factors:
Continuous insulation
Continuous R-25 insulation with no thermal bridges, which reduces heat loss and improves the building’s energy efficiency.
No thermal bridging
The insulating core creates a complete separation between the inside and outside of the wall, eliminating thermal bridges.
Stabilizing the indoor temperature
Thanks to its thermal mass, the wall stores and redistributes heat and cooling for stable indoor comfort, summer and winter alike.
Continuous insulation that truly performs
The Type 22 expanded polystyrene core creates continuous insulation with no thermal bridging. The wall delivers a measurable, effective R-25.
This continuity reduces energy losses and improves the overall performance of the envelope.
Thermal mass: a real advantage
The interior architectural concrete finish acts as a thermal reservoir.
It absorbs heat in winter and cooling in summer, then releases them gradually to keep the indoor temperature stable.
The result: better-controlled energy use, summer and winter alike.
In a commercial or institutional building, this stability becomes a real advantage.
Isobloc ZÉRO: same performance, smaller footprint
The concrete composition changes. The performance stays the same.
The system keeps:
• An effective R-25 with no thermal bridges
• Durability guaranteed for 50 years
• Impact resistance
• Repairability
• No maintenance
Energy performance acts on operational carbon. Decarbonation acts on embodied carbon.
Both come together in a single wall.
Building better. One block at a time.
