In-slab heating is when the pipework is installed within the structural slab of the building. We tie the pipe to a ‘sacrificial’ mesh in a spiral fashion. By spiraling it correctly the floor will be evenly heated and not have cold spots. The structural mesh is then placed on top of our pipework and the concrete is poured as per normal. The system is filled with water and pressurised so that it doesn’t collapse and so that if in the unlikely event it is punctured it is visible. On the rare occasion that slab pipes are punctured, we will conduct an emergency repair and re-pressurise the system to ensure it’s integrity.
In-screed heating is where the pipework is installed into a screed or topping slab on top of the structural slab. The benefit of screed heating is that it is insulated underneath and that it is heating a much thinner slab. This makes it more efficient and responsive.
