Understanding the Celotex PIR Insulation Board Range
When selecting Celotex PIR Insulation Boards, you have three primary options to consider: Celotex TB4000, Celotex GA4000, and Celotex XR4000.
What is the difference between Celotex TB4000, GA4000, and XR4000?
The key distinction lies in the thickness of the boards, tailored to accommodate various insulation needs across different building applications.
-
Celotex TB4000 offers thicknesses ranging from 20mm to 40mm. This range is specifically engineered for applications requiring minimal build-up to meet thermal requirements, making it ideal for areas where space conservation is essential, such as internal wall insulation and overcoming thermal bridging.
-
Celotex GA4000 is available in thicknesses from 50mm to 100mm. It is designed for a broad range of applications, providing a versatile solution for walls, floors, and roofs that require standard insulation thicknesses for effective energy conservation and compliance with building regulations.
-
Celotex XR4000 extends from 110mm to 200mm in thickness, suited for projects demanding superior thermal insulation performance.

Frequently Asked Questions About PIR Insulation
What is PIR insulation? PIR (polyisocyanurate) insulation is a type of thermal insulation material used in building and construction. It is known for its excellent thermal performance and high resistance to heat flow, making it an effective solution for reducing energy costs in homes and buildings.
Why is PIR Insulation so expensive? The cost of PIR insulation reflects its superior thermal performance and energy efficiency. The materials and technology used to manufacture PIR insulation are advanced, contributing to its higher price point compared to other insulation types.
Can PIR Insulation get wet? PIR insulation is generally moisture-resistant but not entirely waterproof. While it can withstand some exposure to moisture without losing its insulative properties, prolonged or excessive wetness can affect its performance. It's important to protect PIR insulation from water during installation and use.
Can PIR Insulation be recycled? Recycling PIR insulation can be challenging due to its chemical properties and the presence of fire retardants. However, efforts are being made to improve the recyclability of PIR products as part of the industry's commitment to sustainability.
How much PIR Insulation do I need? The amount of PIR insulation required depends on the specific energy efficiency goals, climate, and the area being insulated. It's best to consult with a professional to calculate the optimal thickness and quantity based on your particular needs.
How is PIR insulation made? PIR insulation is manufactured through a chemical reaction between a polyol and an isocyanate, forming a rigid foam board. This process involves the use of catalysts and blowing agents, which expand the material into a highly insulative foam with a closed-cell structure.
How does PIR Insulation work? PIR insulation works by trapping air within its closed-cell foam structure, significantly reducing heat transfer. This air barrier effectively minimizes the amount of heat that can pass through, helping to maintain a consistent indoor temperature and reduce energy consumption.
What is PIR Insulation made of? PIR insulation is made from polyisocyanurate, a type of plastic known for its excellent fire resistance and thermal properties. It typically features a foil facing to enhance its thermal resistance and moisture barrier.
Where to buy PIR insulation? PIR insulation is available at InsulationUK! We stock a wide range of PIR insulation products from leading brands such as Recticel, Ecotherm, Kingspan, and Xtratherm.
How to cut PIR Insulation? PIR insulation can be cut using a sharp knife or a fine-toothed saw to fit specific measurements.
For precision cuts and to minimize onsite waste and mess, InsulationUK offers a bespoke cutting service. Customers can order PIR boards pre-cut to their exact specifications, ensuring a perfect fit and easier installation.
Key Considerations
When using Celotex insulation boards you need to satisfy yourself that the use of the product meets all relevant national Building Regulations and guidance as well as local, national, and other applicable standards relevant for your construction or application, including requirements concerning fire and applicable height restrictions.
