Thermal Insulation for Ground Bearing and Suspended Floors

Heating is important and many buildings struggle to keep the heat inside during winter. One solution is to put thermal insulation on both sides, above and below, of the floor slabs. This ensures that the thermal mass is excluded from the insulation from above and included in the insulation from below and helps in maintaining the proper temperature in the buildings during winter. It also makes it easier to heat up the building.

Thermal insulation is used for both ground bearing and suspended floors. The floor right on top of the ground is called a ground bearing floor while everything else is suspended. The insulation must be strong and waterproof. The slabs needs to be of low conductivity material, so that the thickness of the insulation can be reduced. It also needs to be able to withstand the load of the floor construction as well as the added load of the activities in the building. As mentioned above, this works well with buildings which need to be heated all the time, and are hence especially valid for homes. This is also used with floor heating and masonry wall constructions.

Different can materials work better with different floor material such as timber and concrete. Ballytherm insulation boards meet the requirements for both applications. It’s durable and resistant to moisture. Additionally, because of low thermal conductivity, the insulation thickness required is reduced.

Adding insulation layers is generally not recommended for amateur do it yourself enthusiasts. It is a good idea to call in the experts because it involves removing, replacement, installations of different components.
