110mm Unilin Thin-R Plus Hyfloor Strip Foundation System

The 110mm Unilin Thin-R Plus Hyfloor Strip Foundation System combines engineered floor insulation with high-performance foundation riser panels made from medium-density block. This innovative system successfully achieves the required U-Values and PSI value detailing, aligning with the Future Homes Standard and passive floor performance criteria.

By incorporating expertly installed and meticulously detailed insulation at the initial stages of any construction project, a multitude of advantages are gained. Accurate detailing at the floor level establishes a benchmark for both thermal efficiency and installation precision across the entire building envelope. Getting the flooring right sets the tone for optimal performance and best practices throughout the entire construction process.

The 110mm Hyfloor Strip Foundation System not only ensures compliance with the Future Homes Standard through its U-Value and Thermal Bridging performance but also guarantees the necessary compressive strength at the foundation level.

4. Attains floor U-Values within the range of 0.11 to 0.13 W/m2K.
5. Utilizes blocks designed for multi-storey structures with remarkable compressive strength.
6. Adheres to standard construction Approved Construction Details (ACDs).
7. Follows a conventional construction approach, eliminating the necessity for engineering assurances.
8. Well-suited for integration with both built-in full-fill and partial-fill wall insulation solutions.

Thermal Bridging

When making a choice between an insulated foundation system and a traditional strip foundation, the process of gauging heat loss and comparing performance is straightforward. The following steps can be taken:

Assess the achieved U-Value pertaining to the floor itself. Evaluate the Psi value, which indicates heat loss through the junction of the wall and floor. Ensure an appropriate f (temperature) factor is employed to prevent surface condensation and mold formation at the skirting level. In general, U-Values that surpass 0.15 W/m2K are usually satisfactory to meet the requirements of the Future Homes Standard. The attained U-Value from a specific floor insulation thickness depends on the ratio of the floor's perimeter to its area (P/A). For instance, using around 150mm of the Hyfloor system typically results in a U-Value ranging from 0.11 to 0.13 W/m2K.
