What is the Best Alternative to PIR Insulation?

Insulation is a crucial component of a well-designed and energy-efficient home. It plays a vital role in regulating indoor temperatures, reducing consumption, and creating a comfortable living environment. Effective insulation can significantly lower heating and cooling costs, making it a valuable investment for homeowners. As energy prices rise, finding the right insulation solution has become increasingly important.

Understanding the Different Types of Insulation Available

The insulation market offers a diverse range of options, each with its unique characteristics and benefits. Traditional insulation materials, such as fiberglass, mineral wool, and polystyrene, have been used for years. However, as building regulations and energy efficiency standards evolve, homeowners are exploring alternative insulation solutions that offer enhanced performance and versatility.

2024 PIR Insulation Price Increase

One of the commonly used insulation materials, PIR insulation, has faced challenges in recent times. Due to supply chain disruptions and global events, the price of PIR insulation has seen a significant increase, up to 20% in some regions. The price hike has prompted homeowners and builders to seek more cost-effective alternatives to deliver similar, if not better, insulation performance.

In the face of the rising costs of PIR insulation, it is essential to explore alternative options that can provide effective without breaking the bank. One such alternative that has gained increasing attention is Multifoil Insulation.

One example of the increase is to Celotex PL4000 62.5mm insulated plasterboard. This material had an increase on both the 1st June & 1st July 2024. SuperQuilt would be a direct replacement to a 62.5mm insulated plasterboard, but would cost approx £17.72 per m2, compared to under £8 per m2 on SuperQuilt (based on trade pallet deals)

Below are a list of other increases, implemented by PIR manufacturers;

  • Kingspan Insulation – Between 4% & 10% – Effective from 1st August 2024
    • Ranges include Therma Range, EcoTherm Range & Kooltherm Range
  • Unilin Insulation (Formerly Xtratherm) 10% increase – Effective from 1st July 2024, which is in addition to increase which came in 1st June
