RH Nuttall, based in Birmingham, are a leading manufacturer and supplier of all types of Nylatron GSM Thermal Breaks. Nylatron Thermal breaks, or Nylatron Thermal Plates can be made to your exact requirements with bolt holes added to suit. Thermal breaks are used throughout the building trade to provide cold bridging prevention between internal and external horizontal and vertical metal connections. The Nylatron Thermal Break is designed with low thermal conductivity in mind, thus reducing/preventing the flow of thermal energy between the two conductive materials, thus minimising the risk of internal heat loss and condensation.

Given recent climate changes, as well as the need for more efficient housing, tight building regulations stipulate that both heat loss and internal condensation must be considered at the planning stage of building, and therefore Nylatron thermal break connection plates are calculated into the build in order to meet these requirements, reducing thermal transfer from the high thermal conductivity of steelwork structures.

Commonly termed thermal bridge breakers, or beam end plates, our range of components manufactured from Nylatron GSM contain finely divided particles of molybdenum disulphide to enhance its bearing and wear behaviour without impairing the impact and fatigue resistance inherent to unmodified cast nylon grades.

Climate Change Act & Nylatron Thermal Breaks

The Climate Change Act introduced by the UK Government has set a target to reduce national greenhouse gas emissions by 34% by 2020 (compared to data analysed in 1990), with an overall ambition of further reducing it to at least 80% by 2050. A high percentage of these emissions come from buildings, and therefore minimising these through cold bridge building techniques has become imperative.

Thermal bridges happen when the building envelope is penetrated by any material with a high level of thermal conductivity, thus providing a breach in the insulation of the building. More energy from the inside of the structure would then be required to maintain current heat levels. Furthermore, cold surfaces can lead to condensation occurring within the building, normally resulting in the appearance of mould growth. U values are calculated on the building envelope at design stage, and thermal bridging aspects incorporated.

Our Nylatron GSM thermal breaks are made to measure upon request, and added in between the steel and brickwork to eliminate thermal loss due to their low thermal conductivity.

Design requirements of Nylatron Thermal Breaks

As every building envelope is designed differently it is near impossible for RH Nuttall to determine and calculate the thermal performance of it, we therefore request a fully dimensional drawing to produce our Nylatron GSM thermal breaks from. To fully ensure we meet the requirements needed, the requisitioner should ensure all aspects of B25250:2011 are met. Guidance on avoiding problems with high moisture levels, excessive humidity and condensation in the building are all covered in this directive. From here all U value calculations can be done on the local steel structures that are to penetrate the building envelope, and Nylatron Thermal Breaks can be manufactured to suit.

Please note that items such as beam end plates, thermal breaks and bridge breakers manufactured from Nylatron GSM are inherently more compressible than steel in nature, and therefore deflections, wear, mechanical properties and strength should be calculated at the design stage before a part is stipulated.
Thermal conductivity and load bearing data of our high specification Nylatron Thermal Breaks are both readily available on request. Please note that it is the project designer/architect’s responsibility to calculate the requirements regarding heat loss and condensation levels in accordance to meet building regulations.
