Whether you are a large, established rendering company, a homeowner or anyone in between trust Licata to provide for all your needs. Our products embody years of R&D, are produced to the highest standards of quality and stand the test of time.
Licata’s steel frame EWI system is carefully designed to limit thermal bridging across steel frame constructions. Using mineral wool insulation with a high-density sheathing board helps achieve consistent thermal conductivity values across frame walls, ensuring reliable performance for both new build projects and retrofit applications.
Each layer, from basecoat to thin coat render, is part of a balanced combination that controls heat transfer and improves building efficiency. Tested to UK building regulations, this system helps achieve the desired target U-value while maintaining breathability, durability, and long-term protection for external walls.
The mineral wool insulation used in Licata’s steel framing systems is A1 non-combustible and offers outstanding fire performance for all building types, including high rise developments. It also provides excellent thermal conductivity, helping buildings achieve energy-efficient results while staying compliant with UK building regulations.
This insulation is lightweight, water repellent, and easy to cut with a sharp knife, allowing installers to shape it accurately to the dimensions of studs and boards. Combined with silicone or acrylic finishes, it forms a strong, breathable envelope that is suitable for steel-framed construction of any height.
Licata’s external wall insulation systems integrate vapour control layers and breathable water repellent coatings that prevent condensation behind steel frame walls. The sheathing board and basecoat work in conjunction to form a stable barrier that allows moisture diffusion while eliminating the risk of trapped dampness.
This construction form ensures lasting durability and prevents mould in both new build projects and retrofit applications. By maintaining the correct thermal conductivity and airflow balance, Licata’s systems continue to deliver high performance while protecting the structure from moisture damage.
Licata’s steel frame external wall insulation system meets the highest UK fire performance standards. The mineral wool insulation holds A1 fire classification, making it a trusted choice for high rise buildings. All products are manufactured and tested to meet national and European requirements for façade and cladding systems.
Every component, from sheathing boards to fixings, is supplied under strict manufacturer quality control to ensure consistent performance. Combined with thin coat silicone finishes, the system maintains its durability and appearance without compromising fire safety or thermal efficiency.
Yes, heavy fixtures can be securely attached when proper guidance and details are followed. Installers should fix directly into the steel studs or sheathing board instead of the insulation or thin coat layers alone, ensuring structural performance is not affected.
Licata provides technical support and installation details for each application, helping professionals achieve compliance with building regulations. With the correct fixings and reinforcement, the external face of the system remains safe, stable, and visually consistent across all buildings.
