150mm Unilin Hyfloor Strip Foundation System

The 150mm Unilin Hyfloor Strip Foundation System delivers engineered floor insulation paired with high-performance foundation riser panels constructed from medium-density block. This advanced system meets required U-Values and PSI value specifications, satisfying the Future Homes Standard and passive floor performance requirements.

Installing premium insulation during the initial construction phase delivers substantial benefits. Precise detailing at foundation level establishes the standard for thermal performance and installation quality throughout the building envelope. Proper foundation detailing creates the foundation for consistent performance across the entire structure.

This 150mm Hyfloor Strip Foundation System delivers Future Homes Standard compliance through superior U-Value and thermal bridging performance whilst maintaining essential compressive strength at foundation level.

Key Highlights

1. Incorporates site detailing from the outset of the project.
2. Achieves impressive Y-Values of less than 0.05.
3. Boasts an exceptional lambda value of 0.021 W/mK.
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

Comparing an insulated foundation system against conventional strip foundations requires straightforward heat loss assessment. The evaluation process involves:

Determining the achieved U-Value for the floor assembly. Calculating the Psi value, which quantifies heat loss at the wall and floor junction. Selecting an appropriate f (temperature) factor to prevent surface condensation and mould growth at skirting level. U-Values exceeding 0.15 W/m2K typically satisfy Future Homes Standard requirements. The resulting U-Value from specific floor insulation thickness depends on the perimeter-to-area ratio (P/A). Approximately 150mm of the Hyfloor system typically delivers U-Values between 0.11 and 0.13 W/m2K.
