Unilin XT/HYF Hyfloor Strip System 150x450x1200mm is a floor insulation system with high performance foundation riser panels used to achieve Future Homes Standard and passive floor performance.

The Hyfloor Strip Foundation System provides effective insulation that has been detailed and installed professionally at the initial stages of any building project, and has multiple benefits.

Detailing properly at floor level sets the standard for the thermal performances and installation accuracy of the total building envelope; get the floor right and good practice is set for the rest of the build.

Hyfloor Strip Foundation System provides U-Value and Thermal Bridging performance to meet Future Homes Standard along with assurance of high compressive strength at foundation level.

Traditionally, insulating at floor level didn’t receive the attention by designers and site operatives that is now required to meet Future Homes Standard or Passive standards.

The real disconnect however is the relationship between the installation of the floor insulation and the wall insulation.

Typically completed as two separate skills at different times, and often by different teams, without consideration of the effect on Thermal Bridging at the wall/floor junction.

Unilin’s Floor & Foundation system supplies the designer with a traditional system that provides thermal performance and robust detailing.

 · Excellent 0.021 W/mK lambda value.

 · Floor U-Values achieved 0.11 - 0.13 W/m2k.

 · Complies with standard construction ACDs

 · Addresses site detailing from an early stage.

 · Using blocks suitable for multi-storey buildings with a high compressive strength.

 · Traditional construction, avoiding the need for engineering assurances.

 · Suitable for use with built-in full fill and partial fill wall insulation.

Hyfloor Strip Foundation System XT/HYF Installation Guidelines:

 · Installing the Hyfloor insulation along with the foundation strip insulation at ground work stage ensures a thermally efficient junction.

 · The inclusion of a medium density block provides a full suitable base for loading requirements.

 · At this stage, (before the outer leaf is built) inspection and sign off of this critical junction can ensure compliance with the ACDs.

 · Traditionally, block work contractors are relied upon to provide this robust detailing after riser walls have been built to DPC level.

 · This normally entails pushing insulation into a cavity from above in contravention of SR325 guidance.

 · Where the DPC is folded at wall-floor junctions it doubles in thickness which pushes out the insulation and causes issues within the cavity.

 · Riser board has a 20mm fleece which can compensate for this while still maintaining the thermal efficiency of the insulation and integrity of the cavity offering a simple solution to a typically complicated problem.
