Reasons To Choose Eps Over Pir Insulation

Reasons To Choose Eps Over Pir Insulation

Expanded Polystyrene, known as EPS or airpop, has been in use for decades. It is a versatile material that is used for numerous products, including insulation, packaging, safety equipment, artwork, and even civil engineering applications. Many everyday products are made from EPS using both new and recycled materials.

Applications for EPS include:

  • Cavity Wall Insulation (Bonded Bead for full fill and partial fill applications)
  • Floor insulation
  • Insulated Foundation Systems
  • Attic and Roof Insulation
  • Pipe Insulation
  • External Wall Insulation

Let’s take a look at some of the benefits of EPS as an alternative to PIR insulation.

EPS is an extremely durable material

Expanded polystyrene will last the lifetime of any building where it’s installed. The thermal performance of EPS does not degrade over time, meaning the U-value you first achieve with EPS will not change. Unlike other insulation materials, like PIR, EPS does not off-gas, meaning the thermal conductivity stated on the Declaration of Performance certificate is what you’ll receive.

In addition, EPS is rot-proof, mold, water, and moisture resistant due to its closed cell matrix of 98 percent air and 2 percent EPS. A flame retardant is added to all the EPS we manufacture.

EPS is cost-effective

The PIR shortage has meant supply cannot keep up with demand. Lead times are currently several weeks and limits may be placed on the quantity that can be purchased. As a result, the price of PIR has risen in many markets.

EPS quick delivery

Many of our EPS insulation solutions can be manufactured and delivered to the site in just a few days, meaning your project won’t be held up while you’re waiting on material to become available. We can even accommodate the most urgent requests without compromising on quality. Insulationuk delivers throughout the UK usually within 5 working days.

EPS is a stable material

Expanded Polystyrene is an extremely stable material, containing no CFCs or HCFCs. It is chemically inert and can be safely handled on the job site without requiring specialized equipment. As stated, the performance of EPS will not degrade over time, providing consistent thermal performance for decades.

EPS is sustainable and can be recycled when its useful life has been reached.

Whether you’re retrofitting an existing building or planning a new build, EPS can help you achieve your low-energy goals at a cost that is much less than our competitors
