What are PUR and PIR?

PUR stands for Polyurethane Insulation, whilst PIR stands for Polyisocyanurate Insulation.

Essentially, PUR and PIR insulation are both very like each other. They are both rigid forms of thermal insulation that are manufactured from plastic to create a foam. PUR insulation has been in use since the 1960s, whilst PIR is considered as the “next generation”.

PUR and PIR are suitable for use in a wide range of applications:

  • Walls –Ecoliner products are suitable for insulating and drylining internal walls, whilst Eco-Versal offers timber frame walls thermal insulation with both faces including aluminium foil. As the name suggests, Eco Cavity is used in Cavity/Masonry Walls and are designed to work with the typical dimensions of brick and block.
  • Flooring – Suitable for most types of flooring including timber, solid and concrete, as well as suspended flooring, it is crucial to ensure that floors are fully insulated to tackle the problem of heat rising.
  • Lofts – Loft spaces are a void that is the most common cause for heat loss, so choosing a good form of insulation such as PUR or PIR will help to save you money, whilst ensuring that your home is energy efficient.

Eco-Versal is a popular choice of PIR insulation because it is effective at insulating a wide range of areas of your home including pitched roofing, walls, loft ceiling and floors.
