U-Values

The development of thermal performance in doorsets has become important to assist with improving energy efficiency in the home and commercial buildings. At JCK Joinery we strive to continue to lower the U-values of our doorsets.

We currently have some of the lowest U-value doorsets in the UK, with ratings below 1.0 W/m2k. Our Technical department has the technology to calculate U-values for the most bespoke doorsets.

Our thermally efficient doorsets are manufactured in accordance with EN ISO 10077 – 2:2007.
