Product Description

Thermal Insulation - Glasswool Wall and Floor SupaBattsB&B Insulations Glasswool Wall & Floor SupaBatts are silent and compressible insulation manufactured from the controlled felting of glasswool bonded with a thermosetting resin.

Glasswool Wall & Floor SupaBatts have a special treatment added to increase their ability to repel water which gives added protection to internal walls from possible water damage. Glasswool Wall & Floor SupaBatts will not burn and will provide excellent thermal and acoustic insulation in the home.


Glasswool Wall & Floor SupaBatts are manufactured to a controlled thickness so that installation in walls can be achieved without the insulation contacting the external walls. Glasswool Wall & Floor SupaBatts should be retained in position with string so that ventilation of the wall cavity is preserved. Glasswool Wall& Floor SupaBatts will both increase comfort and reduce energy bills in the home by keeping heat out during summer and heat in during winter.

Glasswool Wall & Floor SupaBatts will also reduce noise entering the home when installed in the external walls, or reduce noise transfer between rooms when installed in the internal walls. Glasswool Wall & FloorSupaBatts are supplied in two convenient widths to suit standard housing construction: 430mm width for450mm stud centres, and 580mm width for 600mm stud centres.

For safe handling instructions please refer to MSDS sheet.
