The development of thermal performance doorsets has become important to assist with improving energy efficiency in the home and commercial buildings.  At JCK By System’ 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.

Chain of Custody timber

At JCK By System' we can supply our products in a variety of timbers which come from sustainable sources with Chain of Custody (CoC) certification either with the PEFC or FSC®  Badge

Below is a quick reference table which enables you to see what timbers can be CoC certified, the general availability for them, and what additional extra you can expect to pay for CoC material (this is just for the CoC timber element not the entire product).

If you would like more general information on what is PEFC and FSC® please follow the link to our general information page for Chain of Custody.
