FIRE RETARDANT TIMBER TREATMENT

Specialist Fire Retardant Timber Treatment

With a growing number of commercial and residential projects requiring fire retardant timber, it’s vital that timber merchants, builders, developers and contractors can prove the timber they’re using has been adequately treated to the exact specifications required for their project.

As specialists in fire retardant timber and plywood treatment, we work with our customers to help them meet and understand the compliance requirements surrounding fire-retardant treatments for timber materials. We do this by using BURNBLOCK, a fire treatment, which is continuously being developed to quickly meet any change in standards within the ever-evolving timber market.

Performance Backed By Data, Testing & Certification

Through the use of an autoclave, we use the latest high-pressure treatment technology to impregnate BURNBLOCK fire retardant into a variety of timber and plywood species, as well as scaffolding and external timber cladding such as siberian larch. This is done in a dedicated facility within a controlled factory environment, and as the treatment is clear and transparent, it doesn’t leave any visible stains or imperfections in the timber.

Our specialist kiln drying facility allows us to return timber to an appropriate or specified moisture level post-treatment, supporting construction standards to hold 10–18% moisture.

We Offer Everything You Need

We ensure you're given everything you need to be confident that your timber is treated correctly, is fully traceable and meets UKCA/CE standards.

Our FireWright Treatment Process

1. Upon receipt of your timber, we check the moisture content to ensure it’s below 25% and so can start treatment.

2. Timber is placed into the high pressure autoclave for treatment. This process can take between 1.5 - 20 hours depending on the timber species.

3. Once pressure treated, the timber is restacked as required. The timber is then put into the kiln for drying. This process can take anywhere from 6 to 24 days depending on the timber species.

4. The kiln drying process is constantly monitored with probes to ensure optimum drying conditions.

5. As a final check, the timber has achieved the target moisture content a small sample is taken from the batch and weighed. The sample is then placed in an oven for 16 hours. The resultant weight is then subtracted from the initial weight to confirm the actual moisture content of the timber.

6. When this process is finished, the timber is left for 24 hours, before being placed back into the packs it arrived in and wrapped up ready for collection/delivery.
