PIR plat dak

Introduction; what do we start with?

A flat roof offers several advantages, such as extra space and easy maintenance. However, to maintain an optimal indoor climate and ensure energy efficiency, it is crucial to properly insulate the roof. A popular insulation method for flat roofs with EPDM is the use of PIR insulation . In this blog article we take a closer look at the benefits and applications of PIR insulation on flat roofs with EPDM roofing.

What is PIR insulation?

Polyisocyanurate (PIR) is a high-quality insulation material that combines excellent thermal properties with a lightweight structure. PIR insulation consists of a plastic foam composed of selected polymers and special additives. This results in a material with a high insulation value, good fire resistance and excellent moisture resistance.

Advantages of PIR insulation on flat roofs with EPDM:

  • Excellent insulation value: PIR insulation has one of the highest insulation values ​​of all common insulation materials. This helps to minimize heat loss in winter and regulate indoor temperatures in summer. This contributes to energy savings and increased comfort in the building.
  • Durability and Longevity: PIR insulation is a durable material that is resistant to aging and degradation. It retains its thermal properties over a long service life, making it a cost-effective long-term investment. In addition, PIR insulation is recyclable and contributes to a reduced ecological footprint.
  • Compatibility with EPDM: PIR insulation is excellent for use in combination with EPDM roofing . It can be placed directly on the roof surface and provides a seamless insulation layer that guarantees watertightness. The compatibility between PIR insulation and EPDM ensures efficient installation and minimizes the risk of leaks or other problems.
  • Lightweight and Easy to Handle: PIR insulation is a lightweight material, making it easy to handle and install. This makes it an attractive choice for flat roofs, where the weight of the insulation material is an important consideration. The lightness of PIR insulation also simplifies transport and reduces the load on the roof.

Applications of PIR insulation on flat roofs with EPDM:

  • PIR insulation can be used in a variety of situations on EPDM flat roofs, including:
  • New construction projects : In the construction of new buildings, PIR insulation can be applied to create a thermally efficient roof that meets energy performance standards.
  • Renovations : When renovating existing roofs, PIR insulation can be applied to improve energy efficiency and extend the lifespan of the roof.
  • Green roofs : PIR insulation can also be used as a basis for green roofs, where the insulation layer helps maintain the desired temperature and reduce the load on the roof structure.
