Thermal insulation

Let’s develop the next step of your insulation process.

Sandwich panels, roof tiles and doors with a rigid foam core.

The process

How polyurethane is used in panels and roof tiles

Sandwich panels and insulated roof tiles combine metal facings with a rigid polyurethane (PUR) or polyisocyanurate (PIR) foam core. The core insulates, bonds the facings and gives the assembly its stiffness.

Production can be discontinuous — injection in presses or moulds — or continuous, on double-belt lines. Either way, the project starts from the product, thickness, capacity and the desired level of automation.

Steps

Typical process flow

  1. 01 Facings Sheet preparation and preheating.
  2. 02 Metering Output matched to line speed.
  3. 03 Laydown Even distribution of the mix.
  4. 04 Expansion Heated press or double belt.
  5. 05 Cutting Cutting and stacking.

Reference flow. Each project defines the steps included and each supplier’s responsibilities.

Questions to start the project

You do not need every answer. They structure the conversation with our engineering team and with your PU system supplier.
