Embodied Carbon Report of our Moulded GRP Products
This Eco Report gives insights into the environmental impact of 1kg of our moulded GRP products. Dura moulded products provide the engineer with a high degree of design freedom and offers exceptional material properties for a wide range of applications. Our moulded products are manufactured using orthophthalic (Ortho) resin as standard.

Embodied Carbon Report of our Pultruded GRP Products
This Eco Report gives insights into the environmental impact of 1kg of our pultruded GRP products. Pultrusion Standard BS EN 13706 defines two performance grades, namely E17 and E23, with our pultrusions designed to meet or exceed the higher performance E23 grade. Dura Pultruded Profiles provide the engineer with a high degree of design freedom and offers exceptional material properties for a wide range of applications. Our pultrusions are manufactured using isophthalic (ISO) resin as standard, with production lengths ranging from approximately 3 metres to 6 metre lengths by product.
