Jablite Jabfloor High Performance insulation is supplied in
a standard board size 2400mm x 1200 mm


+Which thicknesses are available to order in Jabfloor HP?
There are standard thicknesses which are 25, 30, 40, 50, 60, 75, 100, 120, 150 and 200mm. However, other thicknesses are available to order.
+Can Jabfloor be used in all floor applications?
Yes, Jabfloor and Jabfloor HP are the most versatile insulants for use in all floor specifications and are available in: • A wide range of compressive strengths from 70kPa grade to 500kPa. • A wide range of thicknesses
+Is a damp proof membrane required when Jabfloor is placed over a beam & block floor?
No. In a suspended/ventilated beam & block floor, a damp proof membrane is not required. A radon membrane may be required in certain areas.
+What is the difference between Jabfloor and Jabfloor HP?
Jabfloor HP (High Performance) offers a more thermally efficient insulant to achieve lower U-values with a thinner board. It is a dark grey in colour making it easy to distinguish from its sister product Jabfloor which is white.
