Add Fire Protection to our wooden doors

“Provide extra peace of mind by upgrading our Ledge and Brace Doors to offer 30 or 60 minutes fire protection by applying specialist fire retardant (intumescent paint) coatings to both sides of the door. This coating expands in heat to create a char barrier. You will see from the picture the different the coating can make. A price for coating the doors is available upon request.

The two distinct standards which govern timber substrates are fire resistance and flame retardation.

Fire Resistance (Resistance to Penetration of Fire)

This regulation requires the timber substrate to maintain structural or compartmentation ability for 30 or 60 minutes. Compliance is determined by a fire test, which has to prove the duration through which an intumescent paint on a given timber product can maintain the integrity of the product. The rate of burn of timber substrates (the charring rate) is also taken into consideration. In simple terms, low-density softwoods burn faster than high-density hardwoods, and this means that they need to be much thicker in order to achieve results similar to hardwoods.

Flame Retardation (Resistance to Surface Spread of Flame)

This regulation targets the ability to prevent flames from spreading across the surface of a substrate.

There are two different approaches to this classification:

• Class 0 & Class 1 – a UK classification, which is being superseded by European classification.
• SBI – a European classification which measures the energy released and the smoke production during a fire test.”
