Wood fire retardant paint fx guard12/18/2023 BS 476 Part 22 Fire tests on building materials and structures – Methods for determination of the fire resistance of non-loadbearing elements of construction.Which obviously deals with the bits holding up the building. BS 476 Part 21 Fire tests on building materials and structures – Methods for determination of the fire resistance of loadbearing elements of construction.This is an overview of the legislation and deals with the General Principles of fire resistance. BS 476 Parts 20 Fire tests on building materials and structures – Method for determination of the fire resistance of elements of construction (general principles). ![]() As you might imagine the variation of materials that can be used in the construction of a building can be great and to these ends fire retardant paints can be purchased to cover all the major material types such as steel, plaster (this also includes lath and plaster walls and ceilings) and timber.įurther details on why the BSI is relevant to fire safety is available from the website and the relevant British Standard (BS) are listed below and linked to the relevant area on the BSI website. This level of resistance has to comply with BS 476 Parts 20 – 23 1987 (see below for more information). a 30 minute fire retardant paint will hold a fire back for 30 minutes before it starts to burn through the protective surface coating. To make sure any surfaces comply with this regulation, intumescent varnishes, paints or other coatings are applied to a surface to effectively stop a fire from breaching for the amount of time specified to that product e.g. The fire resistant capabilities of a given material can be rated from 30 minutes to 60 minutes. The basis of this test is to ensure that any coverings do not increase a fires temperature levels or intensity and does not enable it to spread These regulations are stated in BSI BS 476 Part 6. In order for areas of this type to qualify all materials used including any coverings and coatings have to comply to Class 1 Surface Spread of Flame and also a very low ‘fire propagation index’. Is applied to high–risk areas (fire escape routes and corridors etc….) when any surface coatings have to have a very limited ability to also catch fire and combust. This is the lowest fire standard, and is a performance standard for varnish and paint that can be applied to ceilings and walls. ![]() Requires that the paint coating ensures absolutely no spread of fire. Each of the standards is given a code name and part number which are detailed below. Paints are tested under three ‘test standards’ and these are separated in different ‘classes’ set by the British Standard Institute (BSI). The following points cover what you should look for and ensure when selecting paints: Test Standards Metallic Fire Retardant and Resistant Paints – Safety Information.There are a variety of finishes available for Fire Resistant Intumescent and fire retardant paints and coatings including: Coated with multiple layers of non-retardant paints What Finishes are Available?.Intumescent and Fire Retardant paints and other coatings can be applied to most surfaces including ones that are: Hardwoods, such as oak, ash, beech and birchįire retardant coatings and Intumescent Fire Resistant paints are suitable for interior and exterior use including:.Intumescent Paint and Fire Retardant coatings are suitable for use on most structural building materials such as: Where can Fire Retardant and Intumescent Paint be Used? These types of paints are also be know as Fire resistant Paints. This has the effect of creating an insulating coating which in turn then protects any materials from the heat generated by the fire. Intumescent Paints work differently to fire retardant paint instead of releasing a gas they char and swell up when exposed to fire. If you would like additional help and advice in this area call Property Repair Systems on 01626 872 650. it is imperative that the correct level of fire resistance is achieved to ensure that all relevant laws and legislation are adhered to. Once their effectiveness has been proven they can be applied to walls, floors and ceilings in any space. To ensure their effective they are tested against British safety standards BS 476, part 7. They do this by releasing a flame dampening gas once they become hot. Oil based fire retardant paint What are Fire Retardant Paints?Ī Fire Retardant Paints main purpose is stopping flame and fire spreading over a given surface. ![]() Fire Retardant varnishes and sprays are also available. There are really two main types of fire proof paint Fire Retardant Paints and Fire Resistant Paint also known as Intumescent Paint.
