Schools
The use of Granab in schools brings alot of benefits, not least in projects linked to moisture or mould damage. Our systems for this type of project are made of galvanised steel and are consistently made of non-organic material, which is necessary for this type of project. With easy height adjustment of the subfloor system, it adapts to your project while continuously ventilating the air between the concrete or CLT and the floorboards.
