LicataTherm K5 EWI System

Yes, the K5 external wall insulation system is adaptable to curved or uneven façades when installed according to the manufacturer’s installation guidelines. The insulation boards can be cut and shaped on-site to follow the contours of complex designs, making them suitable for both new builds and refurbishment projects.

This flexibility allows the K5 external wall solution to maintain consistent thermal performance even on intricate surfaces. When combined with lightweight polymer modified renders and a decorative thin coat render, it provides a durable and seamless appearance without compromising insulation quality.

The LicataTherm K5 external wall insulation system is applied externally, which means it will not reduce your internal space or living area. The system can be retrofitted externally on masonry walls, making it ideal for existing properties where preserving space is important.

As one of the thinnest commonly used insulation products, it helps with saving space while improving energy performance. The product’s key feature lies in its phenolic insulation core and low thermal conductivity, providing efficiency without sacrificing design flexibility or creating too much external space around openings.

Movement joints in the K5 external wall insulation system are designed to absorb natural expansion and contraction that occur due to temperature changes or UV exposure. These joints are strategically placed in the render finish to maintain maximum structural stability and avoid cracking.

The external wall insulation board is reinforced with glass tissue and metal screw mechanical fixings, allowing flexibility without compromising strength. When finished with thin coat renders and a protective render topcoat, the system remains durable, weather-resistant, and visually seamless.

The K5 external wall insulation requires minimal upkeep. Routine washing and checks of the protective render topcoat are sufficient to maintain appearance and avoid excess heat retention on the surface. The outer layer resists UV rays and dirt accumulation, extending the lifespan of the render.

Licata’s management system ensures consistent quality through every manufacturing process, making the system durable and weatherproof. Occasional inspections of window sills and joints can help preserve thermal performance and appearance throughout the system’s service life.

The K5 external wall insulation from Licata is fully breathable, allowing water vapour to escape while keeping moisture out. This reduces the risk of condensation forming inside masonry walls, ensuring a healthy internal environment.

Thanks to its phenolic insulation core faced with glass tissue, the system balances breathability and insulation. When installed as part of Licata’s superior external insulation system, it prevents excess heat build-up and provides reliable year-round protection for both new builds and refurbishment projects.
