Fire retardant treatment is carried out using industrial autoclave equipment in a controlled factory environment. Timber or wood-based panels are placed inside a sealed treatment vessel where a fire retardant solution is introduced under vacuum and pressure.
This process allows the treatment to penetrate throughout the timber fibres into the cells rather than remaining on the surface, ensuring consistent fire performance across the entire section of the material.
The typical process includes:
Fire retardant timber cladding enables architects and designers to combine the sustainability and aesthetic appeal of timber with the fire performance required for modern construction.
• Enhanced fire performance for timber façade and architectural applications
• Maintains the natural appearance and character of timber
• Pressure impregnated treatment for consistent long-term performance
• Compatible with coating and finishing systems
• Supplied with full fire classification documentation
When specifying fire retardant treated timber products, the required profile, dimensions and machining should be confirmed prior to treatment. Fire retardant treated timber should be supplied in its final finished profile before the treatment process. Re-machining, planing or reprofiling after treatment is not recommended as this may remove treated material from the timber surface and could affect the tested fire performance classification.
For installation purposes, normal site operations such as cutting to length, drilling and fixing are permitted. These activities form part of standard installation practices and do not normally affect the fire retardant performance of the treated timber.
It is therefore important that the correct timber profile, dimensions and machining are specified prior to treatment to ensure the product is supplied ready for installation. Fire performance classifications are based on tested timber species, profile dimensions and installation conditions, and should therefore be considered as part of the overall project specification.
Timber cladding and solid timber profiles are widely used in modern architecture due to their natural appearance, sustainability and design flexibility. In many projects, particularly commercial, education or public buildings, timber used on façades or internally must meet specific fire performance standards.
Fire retardant treatment allows timber cladding and solid timber components to achieve improved reaction-to-fire classifications while retaining their natural aesthetic and durability.
Fire retardant treated timber is commonly used for external cladding and façade systems where enhanced fire performance is required while maintaining the natural appearance of timber.
Typical external applications include:
• Timber façade cladding
• Architectural timber profiles
• External screening systems
• Commercial and residential building façades
• Public sector and infrastructure projects
For external installations, the timber species, durability class and finishing system should be selected appropriately to ensure long-term performance in exposed environments.
