Celotex TB4000 Insulation Boards
(4 Products)Celotex TB4000 offers a targeted solution to one of the most common energy efficiency challenges - thermal bridging. It is specifically engineered to address thermal losses through junctions in building structures, such as around floors, walls, and roofs. TB4000 stands out in the Celotex range for its ability to deliver high thermal resistance with minimal material thickness, making it an ideal choice for applications that require effective insulation in confined or tight spaces. Its low thermal conductivity of just 0.022 W/mK ensures that the desired U-values are achieved without the need for excessive layering, streamlining the installation process while improving overall energy efficiency.

What Is Celotex TB4000?
Within Celotex's product portfolio, TB4000 occupies a unique niche by focusing specifically on mitigating thermal bridging - a critical weak point in building insulation. Specifically formulated to reduce heat loss at critical junctions - where gaps or discontinuities in insulation can lead to significant energy inefficiency - TB4000 provides optimal thermal performance with minimal material thickness.
It is ideal for use in a range of construction projects, including roofs, floors, and walls, where efficient thermal performance is crucial. Its low thermal conductivity of 0.022 W/m·K ensures that it effectively retains heat during colder months and keeps indoor environments cooler in warmer conditions.
What Does TB Mean?
The "TB" in Celotex TB4000 stands for Thermal Bridging. This indicates that the product is designed specifically to address the issue of thermal bridges, which can occur when gaps or discontinuities in insulation materials allow heat to bypass the insulation layer.
How TB4000 Compares to Other Celotex Ranges
- TB (Thermal Bridging) - Specifically engineered to combat thermal bridging, Celotex TB4000 is ideal for eliminating cold spots in areas where heat loss through gaps or discontinuities in insulation is a concern, such as around floors, walls, and roofs.
- GA (General Application) - A versatile insulation range for walls, floors, and roofs, GA4000 offers a balanced combination of performance and ease of installation, suitable for general insulation needs across various construction projects.
- XR (Extra Resistance) - Offering thicker insulation boards, XR products provide maximum thermal resistance, making them ideal for projects requiring high levels of insulation in space-constrained environments or for achieving superior thermal efficiency in demanding applications.
Applications
- Ground Floors:
- Concrete Slab (Perimeter Upstand)
- Beam and Block (Perimeter Upstand)
- Suspended Timber Joists (Perimeter Upstand)
- Upgrading Existing Concrete Slab (Perimeter Upstand)
- External Walls:

- Above Timber Rafters
Celotex TB4000 should not be used in external walls of buildings over 11 metres. Due to recent Building Regulation changes, only non-combustible or limited combustibility insulation is permitted for these applications to enhance fire safety.
Benefits
- Thin, high-performance PIR insulation board designed to eliminate thermal bridging (TB) in roofs, walls, and floors.
- Boasts a low thermal conductivity of 0.022 W/mK, reducing heat loss and enhancing energy efficiency in tight spaces.
- Faced with low-emissivity aluminium foil, improving thermal performance in sealed cavity air spaces and solid wall applications.
- Ideal for use where space is limited, offering effective insulation without adding excessive thickness.
- Lightweight, rigid, and easy to install.
- Moisture-resistant closed-cell structure prevents water absorption, ensuring long-term durability and reliable thermal performance.

Frequently Asked Celotex TB4000 Questions
Can Celotex TB4000 Be Used in Any Building Type?
While versatile, it's important to consult relevant building regulations and standards, especially regarding fire safety and height restrictions for external walls.
Celotex TB4000 carries a Euroclass F Reaction to Fire classification, making it unsuitable for use in the external walls of buildings over a certain height.
Can Celotex TB4000 be Used in Retrofit Projects?
Yes, it is an excellent choice for retrofit and renovation projects. It can be easily integrated into existing structures, whether upgrading an existing concrete slab or improving insulation in suspended timber joists. TB4000 addresses thermal bridging in older buildings and helps meet modern energy efficiency standards.
Does Celotex TB4000 Require any Special Installation Techniques?
Celotex TB4000 is designed for easy installation with minimal complexity. The boards come in large, easy-to-handle 1200mm x 2400mm panels, which reduce the need for additional handling or cutting.
However, as with all insulation products, it is important to follow the manufacturer’s installation guidelines to ensure optimal performance and compliance with building regulations.
What Certifications Does Celotex TB4000 Hold?
Celotex TB4000 is BBA certified, ensuring it has been rigorously tested and found suitable for use in defined roofing, wall, and floor applications when installed and maintained according to the certification guidelines.
