FireWright® Resource HUB

We want to make sure that you have everything you need when considering specifying FireWright® treatment for timber in your project. We understand the importance of getting everything right, especially with fire-safety. We give you everything needed to ensure that you comply with industry standards and that you are equipped with all the relevant documentation.

Documentation is paramount when it comes to fire-safety and specifying FR treated material in projects. Correct documentation can ensure traceability of materials and treatment whilst giving you the necessary data-backed evidence needed.

Below is a list of the resources we have put together throughout a number of years that can help you further understand the treatment, our process and the relevant documentation required for FR treated timber and plywood.

Documentation

Below are some example documents and explainations for what you can expect when you send your material to be treated with us.

Declaration of Performance

As defined a Declaration of Performance (DoP) is a legal document that describes the performance of a construction product and is required for most construction products on the European market. A DoP is a key part of the European Construction Products Regulation (CPR). It helps increase transparency and improves the functioning of the Single Market.

FireWright® treatment comes with this document as standard with every treatment. This ensures our customers that the performance of the FR treated timber or wood-based panel meets the expected performance whilst also giving transparency to consumers.

Example Declaration of Performance

Constancy of Performance

Constancy of Performance (CoP) is a system that ensures the reliability and accuracy of a product's Declaration of Performance (DoP). The Assessment and Verification of Constancy of Performance (AVCP) system is used to assess products and control the consistency of their assessment results. The AVCP system is used for construction products and is described in the Construction Products Regulation (CPR). Our entire process and factory production manual are both audited annually by our notified body (Finotrol) giving us our CE/UKCA and ISO 9001 certification.

The system classifies products into five levels, each with its own requirements. The AVCP level for a product is defined in its technical specification. The AVCP system includes:

Determining the product type based on testing, calculation, or documentation
Inspecting the manufacturing plant and factory production control
Continuously monitoring, assessing, and evaluating factory production control

The AVCP system ensures that the information in the DoP is accurate and reliable. The DoP is a legal document that provides information about the product and can be used to declare that it meets the requirements for a CE or UKCA conformity mark. A Certificate of Constancy of Performance (COP) is another name for the CE certificate. It's an essential part of UKCA/CE marking and indicates that a product has met the standards of which it claims.

Fire Classification Report

A fire classification report is a document that summarises the results of multiple successful fire resistance tests for a product or material. The report is created by a third party, in our case this is either, Danish Institute of Fire and Security Technology or Forest and Wood Products Research and Development Institute Ltd. Fire classification reports are more useful than individual test reports because they combine data from multiple tests and provide a scope of application.

FR classifications are specific
The classification is specific to the product being tested, and may be subject to additional conditions based on density, thickness, or wood species.

FireWright® An All-Encompassing Solution

FireWright have been independently audited and certified under the Construction Regulation (CPR) in accordance with AVCP system 1. The legal requirements audit factory production control of the fire-retardant facility and ensure the consistency of performance of the manufactured products.

FireWright® Certificates of Constancy of Performance:

Solid wood panelling and cladding – EN 14915:2013 + A1:2017
Wood based panels – EN 13986:2004 + A1:2015

We provide a Declaration of Performance, in line with our CE Mark certification for each of our fire-retardant treatments.

Post Treatment Process

Below are a few guidelines for what to expect from your material after treatment, from properties through to material handling.

Storage of Treated Timber

We treat a range of timber and plywood species, each with varying storage requirements. FireWright returns treated timber fully wrapped unless otherwise stated and plywood unwrapped. Treated material should not be in ground contact and should be stored on pallets where possible.

For packing material post-treatment, we ahere to the below advice and guidance:

Cladding will be returned to customers packed with the working faces facing each other. The sticks will then be added to the back of the cladding to ensure they will not show once installed.
For scaffold boards, we do not use sticks or wrap for this post-treatment. These will be stacked on top of each other and returned.
For plywood, we use softwood battens between each individual sheet. Strictly white and redwood will be used. We do not wrap plywood unless otherwise stated. The only exceptions to this are Birch plywood and decorative panels.

Re-Working & Modification of Treated Material

FireWright’s treatment is an impregnation service, meaning the solution is impregnated into the cell structure of the timber.

Cutting:

FireWright only treats material at finished sizes. We do not allow modifications such as rip-sawing, planing, or thicknessing post-treatment. Treated material can only be cross-cut. Material cannot be cut down the full length.

Sanding:

Only cut ends can be sanded down after treatment. Material faces cannot be sanded.

Drilling:

Treated material can be drilled without the need for post-drilling treatment.

Handling of Treated Material

FireWright fire retardant requires no specific safety equipment, however some data indicates slight irritation should our solution come into direct contact with the eye. The Danish Technological Institute assesses this effect to be less than that of natural lemons and fruit juice. The health assessment shows there are no components listed with any significant health risks in our fire retardant solution.

Fixings & Fastenings

No specialist fixings or fastenings are required with FireWright treated material.

Painting & Staining

No painting or staining should be undertaken pre or post-treatment. Please speak to us directly regarding specific coatings.

Excess Salting

Occasionally timber may show signs of excess salting, i.e. salt showing on the face of the material. This is perfectly acceptable and will fade over time. Should you wish to remove this, only use a warm damp cloth or a dry brush to remove.

Kilning

All solid wood and panels are kiln dried post treatment unless requested otherwise. The kiln drying process is performed to bring the wood back to its equilibrium moisture content for the environment it is going to be used in. To control the kiln drying process we need to monitor the moisture content by placing probes into the product. To achieve this sacrificial timber is required unless the probe holes are acceptable in the treated product.

We have a large kiln capacity which helps us to reduce our lead times for treatment services. Kiln drying is a standard part of the FireWright treatment process however timber like scaffold boards, do not go through a drying process.
