Jabfloor Classic 70 has a nominal 1% compression value of 21kPa equating to 2.1 tonnes per m², which means that Jabfloor Classic 70 will accept up to 600mm of wet concrete. Higher grades of Jabfloor Classic will accept heavier weights and greater depths of concrete.

Jabfloor Classic 70 has a nominal 1% compression value of 21kPa (2.1 tonnes per m²), which is suitable under a 75mm screed in normal domestic situations. The advice of a structural engineer should be sought for any exceptional point loads in the design of the floor.

No. Jabfloor Classic should be tightly butted against the perimeter walls and insulation strip should be used on all exposed edges. An expansion gap may be necessary around the edge of the floor finish in screed or particleboard overlay.

No. In a standard suspended/ventilated (not in contact with ground) beam & block floor, a damp proof membrane is not normally required. A radon membrane may be required in certain areas.

Jabfloor Classic may be placed above or below the damp proof membrane. Jablite EPS is a non-biodegradable material which will be unaffected by ground moisture.

Yes. So long as an approved layer (e.g. chipboard/screed) is positioned between the laminate or tiles and the Jabfloor Classic there should be no problem.

This depends upon the type of screed and construction of the floor. For a sand and cement screed the recommended thickness is 75mm with a minimum 65mm. For anhydrite screeds advice on recommended thickness should be sought from the manufacturer.

Yes. All joints should be taped to ensure boards do not separate during the pouring of the screed/slab.

This depends on the Perimeter / Area (P/A) ratio and the construction of the floor. For example to achieve a U-Value of 0.25 using a ground supported floor:

• P/A ratio 0.25 you would need 40mm Jabfloor Classic
• P/A ratio 0.35 you would need 60mm Jabfloor Classic
• P/A ratio 0.50 you would need 70mm Jabfloor Classic
• P/A ratio 0.70 you would need 80mm Jabfloor Classic

Our Technical Department can carry out U-value calculations based on your construction details.

Jabfloor Classic is white in colour whereas Jabfloor Premium is grey due to the addition of carbon to increase thermal performance. Jabfloor Premium material is more thermally efficient and achieves lower U-values. It also contains Jablite orange speckles.

Jablite Dynamic Insulation has the lowest U-values of any conventional insulation material. U-values as low as 0.07W/m²K are possible

• Dynamic insulation has air channels that air is drawn into
• The air is pre-warmed by heat that would otherwise escape the building
• The pre-warmed air is then drawn back into the property, typically via a Positive Input Ventilation system

Jablite Dynamic Cavity is available for new build masonry construction

Jablite Dynamic External is available for retrofit external wall insulation applications and can typically achieve a U-value of 0.20W/m²K.

Yes, Jabfloor Classic is the most versatile insulant for use in all floor specifications and is available in:

• A wide range of compressive strengths from 70kPa grade to 500kPa.
• A wide range of thicknesses
