Insulating masonry exterior walls from the outside
Is your façade in need of renovation? Do you have no space to lose inside? Are there other reasons why insulating from the inside isn’t an option? No worries!
Our external insulation solutions give you the opportunity to reduce heat loss, lower your energy consumption, and make your building more comfortable. You quickly and efficiently create a continuous insulation layer on the outside, eliminating thermal bridges, all while enjoying a more pleasant indoor climate and reduced energy costs.

The benefits of external insulation at a glance
- External insulation offers highly effective protection against heat loss, as it creates a continuous layer around your home — free of thermal bridges.
- No loss of interior space: Since the insulation is applied on the outside, you retain all your valuable interior space and avoid major alterations to your interior.
- Quick installation: Depending on the situation, external insulation can often be applied faster than complex interior renovation projects.
- Added wall protection: The cladding applied over the external insulation shields the existing structure from harsh weather conditions, extending its lifespan.
- Aesthetic upgrade: External insulation gives you the chance to renew and enhance your façade with a fresh finish, improving the overall appearance of the building.
What does our solution ‘Insulating exterior walls from the outside’ consist of?
Across all our solutions, there is one core principle that we at ISOPROC consistently uphold: good insulation is more than just a thick layer of insulating material.
Wind, temperature differences, and mechanical ventilation cause pressure differences between the inside and outside of a building. Even the smallest gaps or cracks in the building envelope allow uncontrolled air exchange. This undermines the effectiveness of the insulation. In winter, this not only causes energy loss and reduced comfort but can also lead to condensation, mould, and a compromised ventilation system. In summer, those same uncontrolled airflows increase the risk of overheating.
That’s why airtight and windtight construction is just as essential as thermal insulation, and this principle is reflected in all our systems.
