Production Treatments

A number of optional environmentally-sensitive treatments can be added to ESL®/ESB®/CLST™ during manufacture.

All of the treatments are added during the manufacturing process so that the entire Lignor product is protected — not just the periphery/envelope. These periphery/envelope treatments are useless once such treated timber is further machined.

Rot-resistant treatment: An environmentally friendly anti-fungal inhibiting agent.

Termite treatment: An environmentally friendly termite inhibitor treatment is used to deter termite attack. The basic ingredient in the treatment is a common mineral found present in human food, and when burnt does not give off any toxic substances. This treatment replaces the need for potentially hazardous toxic treatments post-production, such as in many old container floors which cannot be disposed of in the First World.

Fire retardant: Even without fire retardant, Lignor’s char rate is approximately half the rate of softwood, meaning narrower members can be used to achieve the same fire rating even before further improving Lignor’s fire resistance with added fire retardant. (Currently under testing) Environmentally friendly non-toxic fire retardant can be added. The fire retardant is free of heavy metals and halogens and already been proven to increase fire-resistance in existing softwood Engineered Wood Products.

Further Surface hardening treatment: This post-production optional extra using ‘resined’ or Kraft paper to seal the surface and make the ESB®/ESL®/ CLST™ much more resistant to scratches and wear. This optional treatment can be a smooth finish, e.g. for concrete form-work or given an anti-slip surface, e.g. on scaffolding planks. Kraft paper greatly improves the surface wear characteristics and has been trialled in a warehouse for months’ use under heavy forklift traffic. The Kraft paper is so hard it blunts tungsten carbide-tipped saws!
