Celotex PIR insulation is a high-performance insulation board widely used in the construction industry for its exceptional thermal efficiency and versatility. It is a rigid foam board made from polyisocyanurate (PIR), a closed-cell material known for its excellent insulation properties and slim profile.

Celotex PIR insulation boards are available in a wide range of thicknesses, from 12mm to 200mm, making them suitable for various applications, including walls, roofs, floors, and ceilings. They are also available in different sizes and edge profiles to meet specific project requirements.

The Benefits

Celotex insulation offers several benefits that make it a popular choice for both new builds and renovations:

• High Thermal Performance: Celotex PIR thermal insulation has one of the highest R-values per inch of any commonly available insulation material. This means it can achieve excellent thermal performance with minimal thickness, making it ideal for applications where space is limited.
• Moisture Resistance: Celotex PIR insulation is resistant to moisture, helping to prevent dampness, condensation, and mould growth. This contributes to a healthier and more comfortable indoor environment.
• Fire Resistance: Celotex PIR thermal insulation boards have good fire-resistant properties, contributing to the overall fire safety of your building.
• Lightweight and Easy to Install: PIR insulation boards are lightweight and easy to handle, cut, and install. This makes them suitable for both DIY enthusiasts and professional installers.
• Environmentally Friendly: Celotex PIR insulation is manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). 

Applications of PIR Insulation Boards

Celotex insulation can be used in a variety of applications, including:

• Pitched Roofs: Install between and over rafters to reduce heat loss and improve energy efficiency.
• Flat Roofs: Use in warm roof constructions to provide a continuous layer of insulation.
• Walls: Suitable for both internal and external wall insulation, including timber frame walls, masonry cavity walls, and solid walls.
• Floors: Can be used to insulate floors, both above and below the screed, to reduce heat loss and improve underfoot comfort.

Choosing the Right Celotex PIR Insulation

Celotex offers a range of PIR insulation boards with different thicknesses and specifications to suit various applications. The most common types are:

• Celotex TB4000: Available in thicknesses from 12mm to 40mm, ideal for applications where space is limited, such as internal wall insulation and dry lining.
• Celotex GA4000: Available in thicknesses from 50mm to 100mm, suitable for a wide range of applications, including walls, roofs, and floors.
• Celotex XR4000: Available in thicknesses from 110mm to 200mm, designed for applications requiring high thermal performance, such as pitched roofs and external walls.

When choosing PIR insulation, it is important to consider the following factors:

• The application: Where will the insulation be used?
• The required R-value: What level of thermal resistance is needed?
• The budget: How much are you willing to spend on insulation?

Installation of Celotex PIR Thermal Insulation Boards

Celotex PIR thermal insulation boards are easy to install, but it is important to ensure that they are installed correctly to achieve the best possible results. The boards should be cut to size and fitted snugly between joists, rafters, or studs. It is also important to ensure that all joints are sealed properly to prevent air leakage.
