Applications of PIR Insulation: Versatile Solutions for Every Building Need

PIR (Polyisocyanurate) insulation is a highly versatile and efficient material used across various applications in the construction industry. Here’s how PIR insulation boards serve different building needs effectively:

1. PIR Insulation for Lofts

PIR insulation is ideal for loft applications due to its excellent thermal performance and space-saving characteristics. In lofts, where space for insulation can be limited, PIR’s high R-value per inch allows homeowners to maximise insulation without sacrificing living space. It effectively prevents heat loss through the roof, making it essential for energy conservation in residential properties.

InsulationUK supply a wide range of PIR Insulation for lofts, view the range here.

2. PIR Insulation for Flat Roofs

For flat roofs, PIR insulation provides a robust solution that not only insulates but also contributes to the overall structural integrity of the roofing system. Its resistance to moisture and ability to withstand heavy loads makes PIR insulation suitable for flat roofs that are often subject to ponding water and heavy foot traffic during maintenance. PIR panels can be installed under the roofing membrane to enhance thermal efficiency and prolong the lifespan of the roof.

InsulationUK supply a wide range of PIR Insulation for flat roofs, view the range here.

3. PIR Insulation for Walls

In wall applications, PIR insulation boards are commonly used both in cavity walls and on the interior or exterior surface of walls. The slim profile of PIR boards allows for effective insulation without significantly reducing interior space. For exterior wall applications, PIR insulation can be part of a system that includes a weatherproof layer, enhancing the building's thermal envelope.

InsulationUK supply a wide range of PIR Insulation for walls, view the range here.

4. PIR Insulation for Floors

PIR insulation is an excellent choice for floor applications due to its high compressive strength and minimal thermal bridging. It can be used beneath concrete slabs, within screed layers, or as part of a suspended floor system. PIR insulation helps maintain a stable indoor temperature, reducing the energy required for heating and contributing to a comfortable living or working environment.

InsulationUK supply a wide range of PIR Insulation for floors, view the range here.

5. PIR Insulation for Underfloor Heating

PIR insulation is particularly beneficial when used with underfloor heating systems. It acts as an effective thermal barrier that minimizes downward heat loss, directing the heat upwards into the living space. This enhances the efficiency of the heating system, reduces operational costs, and improves the overall comfort level of the space. The Tekwarm PIR Gridboard is specifically designed for underfloor heating applications, with a gridded face to simplify installation and ensuring optimal heat distribution.

Frequently Asked Questions about PIR Insulation

What is PIR Insulation? PIR (Polyisocyanurate) Insulation is a type of foam board used widely in the construction industry for its excellent thermal properties. PIR boards are known for their high R-value, which provides superior insulation efficiency compared to many other materials.

Where can I buy PIR Insulation? PIR insulation can be purchased from InsulationUK, where we offer a wide range of PIR insulation products suitable for various applications, including floors, walls, roofs, and lofts.

Why is PIR Insulation so expensive? The cost of PIR insulation is often higher than some other insulation types due to its superior thermal performance, durability, and the advanced technology required to manufacture these effective insulation boards.

How is PIR Insulation made? PIR insulation is manufactured through a process that involves the reaction between polyols and isocyanates. This reaction forms a rigid foam board that is then cut to size. The boards are often faced with materials such as aluminium foil to enhance their thermal properties and resistance to moisture.

How does PIR Insulation work? PIR insulation works by trapping air within its cellular structure, which significantly reduces heat transfer. This helps in maintaining a consistent temperature inside buildings, making it highly efficient for energy conservation.

What does PIR Insulation stand for? PIR stands for Polyisocyanurate, a type of plastic typically used in foam form and noted for its thermal insulation properties.

Where to use PIR Insulation? PIR insulation is extremely versatile and can be used in various parts of a building, including loft spaces, flat roofs, walls, floors, and underneath underfloor heating systems.

Can PIR Insulation get wet? PIR insulation can resist moisture to some extent due to its closed-cell structure, but it should be protected from prolonged exposure to water to maintain its insulative properties.

How much PIR Insulation do I need? The amount of PIR insulation needed depends on the specific requirements of the project, including the desired thermal performance and the area to be insulated. It's best to consult with a professional to determine the appropriate thickness and amount.

Can PIR Insulation be recycled? PIR insulation can be challenging to recycle due to its chemical composition and the presence of facings like aluminium or fiberglass. However, efforts are being made to improve the recyclability of these materials.

Is PIR Insulation flammable? PIR insulation is not highly flammable but can burn under certain conditions. It is typically treated with flame retardants to improve its fire resistance.

PIR Insulation: Combustible or Non-Combustible? PIR insulation is considered combustible, but it is designed to meet strict fire safety standards when installed correctly.

PIR Insulation vs Rockwool: PIR insulation offers higher thermal resistance and is lighter and easier to install than Rockwool, which is denser and has better sound insulation and fire resistance properties.
