Celotex T-Break - Celotex TB4000 Range
(previously TB3000) ...
 Combats local thermal bridging and provides reliable long-term energy savings
A multi-purpose insulation board developed to provide simple solutions for overcoming localised thermal bridges. With low emissivity foil facings, TB4000 is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and a low global warming impact.
Benefits
The T-Break name stems from the design function of the range; which is to provide simple solutions to overcome localised thermal bridges. Celotex is unique in being able to offer boards as thin as 12 mm to the market for this purpose.
TB4000 Range products have similar characteristics to the Celotex Tuff-R range but with an un-reinforced core foam.
Applications
Celotex TB4000 can be specified for use in a variety of applications including ... Pitched Roofs, Flat Roofs, Solid Masonry Walls, Timber Framed & Steel Framed systems, and Floors.
Celotex T-Break Board Sizes and Values
Available in a standard board size of 1200 x 2400mm with the following specifications ...

Technical Specification
Please see the Celotex Tuff-R GA4000 page for details of the technical specifications of this thinner version of that product.
Where Celotex T-Break TB4000 should be used
This thinner version can be used in any rafter or joist application where there is the need to minimize thermal bridging and improve U-Values.
Thermal Bridging
To understand thermal bridging more thoroughly, this is where a (often structural) member with poorer thermal performance has a lower thermal resistance. This is a matter of degree and cannot be avoided just minimised. Therefore, there is a need to compensate by increasing the level of general insulation.
To gain a more formal understanding, we quote ...
Surface condensation – thermal bridging Thermal bridging occurs when the continuity of the building fabric is broken by the penetration of an element allowing a significantly higher heat loss than its surroundings.
These ‘bridges’ commonly occur around openings such as lintels, jambs and sills and at wall/roof junctions, wall/floor junctions and where internal walls penetrate the outer fabric.
Thermal bridges provide a ready passage of heat transfer to the outside air and allow a heat flow entirely disproportionate to their surface area resulting in excessive heat losses.
Condensation may occur on the inner surfaces that can damage the dwelling or threaten the health of the occupants.
To minimise the risk of condensation on any inner surface, cold bridging at a floor, wall, roof or other building element should be avoided.
Detailing should be in accordance with the recommendations in Section 8 of BS 5250: 2002 [ CIS link: BS 5250:2002. (the code of practice for control of condensation in buildings + AMD 16119).
Also, to maintain an adequate internal surface temperature and thus minimise the risk of surface condensation, it is recommended that the thermal transmittance (U-value) of any part and at any point of the external fabric does not exceed 1.2 W/m2K.
U-Value - a definition
U-value (or thermal transmittance co-efficient) is a measure of how much heat will pass through one square metre of a structure when the temperatures on either side of the structure differ by 1 degree Celsius (expressed in W/m2K)
