Insulated Concrete Formwork (ICF)
Exceptional Strength and Durability
Solid reinforced concrete walls withstand extreme weather, resist rot and rust, and are designed for long-lasting performance.
Continuous insulation and thermal mass reduce heating/cooling costs and maintain stable indoor temperatures
Superior Energy Efficiency
Concrete core and treated insulation provide multi-hour fire protection, enhancing safety.
Fire Resistance
Lightweight forms simplify assembly, reduce construction steps, and shorten build times.
Fast and Efficient Construction
Insulated Concrete Formwork (ICF) is a Modern Method of Construction (MMC) that combines insulation and structure in a single system. Preformed EPS blocks are assembled on site and filled with concrete to form solid walls. The result is a durable, airtight, and energy-efficient building envelope.
​
TSD are recognised leaders in the design of ICF structures across Ireland and the UK. With over 20 years’ experience and hundreds of completed projects, we bring deep technical knowledge and practical insight to every scheme. Our focus is on delivering efficient, buildable, and cost-effective structural designs that maximise the benefits of ICF for homeowners, developers, and design teams alike.
​
We work with all major ICF systems used in Ireland, including Amvic, Altherm, Thermohouse, and Castleforms, among others, as well as a range of UK and European manufacturers. This independent approach allows us to select the most appropriate system for each project.
​
We collaborate closely with architects, builders, and developers to ensure designs are coordinated, efficient to construct, and aligned with overall project goals.
