ISOBELL - Breathable thermal membrane for mold protection and wall thermal insulation
Isabel: Innovative Thermal and Breathable Membrane for Wall Protection
Isabel is a next–generation solution designed to protect building walls through a unique combination of thermal insulation, breathability, and thin–layer performance. Unlike conventional coatings or bulky insulation systems, Isabel acts as a breathable thermal membrane that regulates indoor comfort, prevents mold formation, and extends the life of building façades.
At the core of Isabel’s innovation lies its patented technology, which integrates advanced thermal regulation with high vapor permeability. This dual functionality allows walls to “breathe” naturally, avoiding the accumulation of humidity and condensation that often lead to mold, deterioration of plaster, and unhealthy indoor environments. While traditional barriers often trap moisture, Isabel ensures a continuous exchange of air and vapor, keeping wall structures dry and functional over time.
Key Characteristics
Thermal Protection in a Thin Layer – Isabel creates an effective thermal barrier without adding significant thickness to the wall, making it ideal for both renovations and new constructions where space and aesthetics matter.
Breathable Technology – Thanks to its vapor–open structure, Isabel prevents condensation and moisture buildup, ensuring healthier and more durable building envelopes.
Mold Resistance – By combining thermal stability with moisture control, Isabel directly tackles one of the most common issues in residential and commercial buildings: mold growth.
Durability and Aesthetic Improvement – Isabel not only enhances technical performance but also improves the visual quality of façades, repairing and protecting even damaged insulation systems.
Patented Innovation – Developed through years of research and testing, Isabel’s formulation and application method are protected by patent, ensuring exclusive performance and reliability on the market.
Applications
Isabel is designed for a wide range of building contexts:
Residential Buildings – Ideal for apartments, houses, and condominiums where occupants seek improved thermal comfort and healthier interiors.
Commercial and Office Spaces – By controlling condensation and stabilizing temperatures, Isabel enhances comfort and reduces maintenance costs.
Restoration and Renovation Projects – Particularly effective for refurbishing façades with existing or damaged insulation systems, Isabel provides a lightweight, high–performance solution that restores both technical and aesthetic quality.
Heritage and Historical Buildings – Its thin and reversible application makes Isabel suitable for delicate interventions where preserving architectural details is essential.
Why Choose Isabel
Traditional thermal insulation systems often force designers and contractors to choose between thickness, breathability, and durability. Isabel eliminates this compromise by delivering all three in one patented product. It ensures energy efficiency, protects against mold, improves indoor well–being, and extends the lifespan of building façades — all while maintaining minimal thickness.
By adopting Isabel, architects, engineers, and building owners can count on a technologically advanced and certified solution that meets modern construction standards while anticipating future demands for sustainability and occupant health.
Conclusion
Isabel is more than a coating: it is an intelligent membrane that transforms the way walls behave. Its patented technology, combining thermal regulation and breathability, makes it a benchmark in building protection and energy efficiency. With Isabel, buildings gain a second skin — thin, strong, and breathable — that guarantees lasting comfort and healthier living environments.
