In this guide, we’re taking a closer look at PIR insulation (Polyisocyanurate) and we’ll help you understand what you need to know for different applications to ensure you make the best choice for your next project.
The Importance of Specifying Insulation
Choosing the right insulation is one of the most important decisions in any construction project. Insulation plays a key role in maintaining a comfortable internal temperature, improving energy efficiency, and lowering heating and cooling costs. However, with so many different types of insulation available, knowing which material to specify for a particular application can be challenging.
Whether it’s a roof, wall, or floor, each area of a building has unique requirements, and using the right insulation for the job can make all the difference.
What is PIR insulation?
PIR stands for polyisocyanurate. PIR insulation is a popular and highly efficient material used to keep buildings warm and energy efficient. It comes in rigid foam boards that are lightweight, easy to handle, and perfect for use in roofs, walls, and floors.
PIR is made up of small cells filled with a gas that has low thermal conductivity. It is created by combining polyol and isocyanate, forming a structure that traps heat and resists moisture.
It is commonly used in construction and industry due to its favourable balance between thermal and physical characteristics. Despite being thin, PIR insulation offers excellent thermal resistance because of its unique properties.
Is PIR Better Than Rockwool?
It depends on what you need: Use PIR in environments where moisture exposure and compressive loads are concerns. PIR has superior compression strength, typically ranging from 150 to 200 kPa or higher, depending on the product and is therefore suitable for applications requiring load-bearing capacity, such as under concrete slabs, flat roofs, or floors.
It is highly moisture-resistant due to its closed-cell structure and does not absorb water, making it ideal for areas prone to dampness or potential water exposure, such as roofs and walls in wet climates. PIR maintains its excellent thermal performance even when exposed to moisture.
PIR insulation is also great when space is tight because it delivers excellent insulation with thinner boards. That’s why it’s so useful in modern construction.
What’s the Difference Between XPS and PIR Insulation?
XPS (Extruded Polystyrene) and PIR are both popular insulation types, but they shine in different areas.
PIR has better thermal performance, meaning it keeps buildings warmer using thinner boards. XPS, however, is more resistant to water, so it’s often used in damp areas like basements or foundations. If you’re looking for high performance in walls and roofs, PIR is the better option.
PIR vs EPS Insulation
EPS (Expanded Polystyrene) is a more budget-friendly insulation and careful consideration must be applied to its application. PIR boards are more effective at keeping heat in and have better fire resistance. This makes PIR ideal for energy-efficient projects where performance really matters.
