UNILIN_RGB_Insulation_Linear638301077077570203

Organisation profile

Unilin Insulation is an Irish manufacturer committed to supporting the construction industry in the delivery of Low and Zero Carbon buildings.

From design stage to the delivery of ‘A’ rated buildings, the construction professional can rely on the expertise and support of the Unilin Insulation team. It is through the interaction between manufacturers, designers, engineers, builders and energy assessors that together we can formulate strategies to ‘Close the Gap’ between design and actual performance on site.

Training aim

The course will present the parameters used to characterize the thermal bridging of given junctions - with the conventions and standards to calculate them - and the routes to comply with Part L.  

Learning objectives

What is thermal bridging?
Key parameters used to quantified thermal bridging:

 - Thermal bridging factor: Y-value

 - Linear thermal transmittance: Psi-value 

 - Temperature factor: fRSI

Part L 2011 compliance methods

Conventions and standards to calculate Y, Psi and fRSI

Competency schemes in Ireland and UK

Software available
