PIR Insulation FAQs
What is the difference between PIR and PUR insulation?
Polyisocyanurate (PIR) and Polyurethane (PUR) are both closed-cell insulation materials that offer exceptional thermal resistance. However, they vary in terms of their chemical compositions. PIR insulation is a type of polyurethane insulation that includes added isocyanates during manufacturing, enhancing its fire resistance and thermal efficiency. PUR insulation, on the other hand, contains a higher percentage of open cells, making it less dense than PIR insulation.
The increased density and fire resistance of PIR insulation make it an ideal choice for applications where stringent fire safety regulations are in place. PUR insulation, with its lower density, is often used in projects where space is a concern, as it provides good insulation while being lighter and more flexible.
What is the difference between PIR and PUR sandwich panels?
PIR and PUR sandwich panels are widely used in the construction industry for roofing, walls, and other structural elements.
PIR sandwich panels offer improved thermal efficiency and better fire resistance compared to PUR sandwich panels. They are commonly used in structures where superior insulation performance and fire safety are essential, such as cold storage facilities and commercial buildings.
What is better insulation than PIR?
One such alternative is Mineral Wool Insulation, which is known for its excellent sound absorption properties, making it an excellent choice for noise-sensitive environments. Another option is Expanded Polystyrene (EPS) insulation, which boasts impressive moisture resistance and is often used in areas with high humidity levels.
For eco-conscious projects, Natural Fiber Insulation, made from renewable resources like cotton, hemp, or sheep's wool, presents an environmentally friendly choice. It is biodegradable, has low embodied energy, and offers good thermal insulation
What does PIR and PUR stand for?
The acronyms PIR and PUR stand for:
- PIR: Polyisocyanurate
- PUR: Polyurethane
These acronyms represent the chemical composition of the insulation materials and are used in the construction industry to differentiate between the two types of insulation.
