When underfloor heating (UFH) needs to be incorporated into a structural floor build-up, it requires careful planning and precise execution. This approach ensures the system is both effective and durable for the long term. Here’s a breakdown of the process, highlighting key considerations for successful installation.
1. Preparing the Floor with High-Density Insulation Panels
The process begins with laying high-density flooring insulation panels across the entire floor area. The type and specification of these panels depend on the project requirements, but they are essential in creating a solid, well-insulated base that enhances the efficiency of the UFH system.
2. Overlaying with Reinforcing Mesh
Once the insulation panels are in place, the next step is to overlay them with reinforcing mesh. This mesh provides structural integrity to the floor while serving as a support for the underfloor heating pipework.
3. Installing the Underfloor Heating Pipework
With the reinforcing mesh laid down, the underfloor heating pipework is then carefully secured to the mesh. Tying the pipework ensures it stays in position during the next stages of the build-up, preventing movement or displacement that could affect the system’s performance.
4. Laying the Screed or Concrete
After the pipework is in place, it is crucial to schedule the screed or concrete laying process promptly. The sooner this step follows, the better, as leaving the system exposed for too long increases the risk of accidental damage.
For projects using liquid screed, there’s an additional step: sealing the insulation. The insulation must be sealed to provide a watertight base. This prevents the liquid screed from seeping through, ensuring a solid and stable foundation.
