GLAPOR Recycled Foamed Glass (RFG)

A key component of Ty-Mawr Lime Ltd’s award-winning Sublime® floor insulation system, the GLAPOR Recycled Foamed Glass (RFG) is a superior loosefill insulating aggregate ideal for use in our limecrete flooring system.

It is now recognised that polythene membranes, retrospectively installed into floor slabs in existing buildings, have the potential to actually cause rising damp problems: A build up of water pressure beneath the membrane moisture will move moisture sideways until it reaches the existing masonry where it will be able to rise within the wall structure. This situation is often exacerbated by use of waterproof cementitious renders and tanking on the walls which trap the moisture within the masonry.

Our flooring system does not include a moisture impermeable barrier (Damp Proof Membrane). The control of ingress of moisture is achieved by using a layer of recycled foamed glass aggregate beneath the slab material. Its non capillary active closed cell structure provides the moisture protection for your floor while remaining vapour open.

This material also has an excellent thermal resistance capability (0.083 W/mk).

We calculate the thickness of this layer to provide a specified U Value, taking into account the length/thickness of perimeter walls, overall floor area etc. Please clck here for a FREE calculation.
