All Envirowall panels and products undergo rigorous testing to confirm their strength and suitability for purpose. We have also ensured that they have been fully assessed under building control regulations and EU environmental standards. As a result, we have received independent verification of Envirowall’s suitability to replace MDF and/or plasterboard in almost any situation, and of our industry-leading green performance.

Weight and load bearing ability

The weight and load bearing ability of Envirowall panels depends on their density – strawboard panels are available in low, medium and high density. However, for comparison purposes, a 12.5mm thick Envirowall paper panel can hold up to 30kg on a single screw. This compares to just 3kg for standard plasterboard. Envirowall strawboard can hold up to 60kg on a single screw.

Impact resistance

Plasterboard is notoriously susceptible to impact damage. Any Envirowall product offers superior impact resistance to plasterboard, and our paper panels and high density strawboard are both rated as offering “high” impact resistance, the same as MDF.

Fire resistance

Untreated Envirowall paper panels were tested for fire propagation in accordance with BS476 and showed nil flame spread. All Envirowall paper panels are deemed fire resistant for up to half an hour or 1 hour and Class 0 surface spread of flame as standard – in other words, non-combustible. Our straw panels, meanwhile, when treated with an additional fire resistant ingredient,  can withstand fire for an hour.

Moisture resistance

All Envirowall panels offer good moisture resistance as standard, something that is an optional (and often expensive) extra for MDF and chipboard. Envirowall has also been tested successfully for resistance to timber destroying fungi.

Environmental standards

Made entirely from waste material, Envirowall meets the highest environmental standards. In particular, all our products are free from formaldehyde, have negligible VOC levels and a low carbon footprint.

Building regulations

Envirowall boards meet England and Wales building regulations and British Standard requirements for a class 0 surface spread of flame.
