Carbon Footprint

The third key sustainability element of I-Joists is that they have an overall negative carbon footprint. Values will vary with design and have been validated by Ecometrica.

Carbon footprint of I-joists -390.78kg

Environmental management system

Environmental considerations are an important factor in the production of I-Joists, James Jones have a certified ISO 14001:2015 environmental management system which guarantees compliance with all current and forthcoming environmental legislation.

FSC® Certification

Sustainable timber supply is integral to the manufacture of I-Joists which are all specified as FSC® certified with product claims independently verified by BM TRADA Certification.

Thermal Performance

Other advantages of using I-joists are their superior strength-to-weight ratio and readily available deep sections (up to 450mm) when compared with solid timber. In this way more insulation can be used within the building envelope and significant savings in heating can be achieved.

The thin web used in I-Joists contributes to minimise repeated thermal bridging in timber frame structures enabling I-Joists to achieve better U-values than solid timber. This property makes I-Joists ideal as a structural member in roofs and walls in low energy buildings.
