How do I install Jablite Jabfloor 70 Polystyrene EPS Insulation?

To install Jablite Jabfloor 70 Polystyrene EPS Insulation, you can follow these steps:

1. Safety Precautions:

  • Make sure you have the necessary safety equipment, including gloves and eye protection.
  • Work in a well-ventilated area, especially if cutting or handling the insulation indoors.

2. Prepare the Work Area:

  • Clear the area of any debris or obstacles.
  • Ensure that the surface where you'll install the Jablite Jabfloor is clean and dry.

3. Cutting the Insulation:

  • Measure and mark the insulation boards to the required size using a straightedge and a marker.
  • Cut the boards to size using a sharp utility knife or a fine-toothed saw. 

4. Fitting the Insulation:

  • Place the cut insulation boards into position, ensuring they fit snugly together without any gaps or overlaps.
  • For underfloor insulation, lay the boards on a level and firm surface. You can use adhesive to secure them in place if necessary.
  • For wall insulation, insert the boards between the wall studs or attach them to the exterior of the wall, depending on your application.
  • In the case of roof insulation, position the boards on the rafters.

5. Securing the Insulation:

  • Use appropriate fixings, adhesive or support structures to ensure the insulation remains in place.
  • For underfloor insulation, cover the insulation boards with a suitable screed or chosen floor covering.
  • For wall insulation, you may need to install a vapour barrier or cladding over the insulation.
  • In roof insulation, consider covering the insulation with roofing felt or other roofing materials.

6. Finishing Touches:

  • Seal any gaps or joints with compatible sealant or tape to enhance the Jablite Jabfloor’s effectiveness, dispose of any waste materials properly, and clean up the work area.
