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 aims to introduce BER assessors and designers to the conventions and standards to use for U-value calculations.

Learning objectives

Definition of U-value and thermal resistance

Definition of parameters to be considered and used to calculate U-value:

  •  Thermal conductivity
  •  Emissivity

  •  Engineered jointing

Code of practice, Standards and conventions to calculate U-values:

  • BR 443
  • EN 6946
  • EN 13370

CE marking
