Fire protection
Sveden Trä fire protection impregnation based on Burnblock technology.
Introduction
Sveden Trä is origin and future. It is conviction and adaptation, pride and responsibility. Sveden Trä is a force that unites. In a world that is looking for shortcuts and quick solutions, Sveden Trä is a promise of something that lasts.
Together with Burnblock, we can offer fire protection impregnation for wood based on Burnblock's technology. The treatment prevents oxygen from reaching the treated object – and without oxygen: no fire.
The treatment is used to create fire-impregnated and fire-rated wood for construction projects with high fire safety requirements.
Fire protection for the future
Our Burnblock fire-retardant treatment is a highly effective and non-toxic treatment based on naturally derived ingredients. The result of this treatment is wood that, when properly handled, can be used in environments with strict fire safety requirements. Our fire-retardant wood is also available with an industrial paint finish. To maintain the classified fire performance, painting must be performed using paint systems and methods that have been tested and certified together, and installation must be carried out according to the recommended instructions.
At Sveden Trä , we Sveden Trä solutions where the impregnation and painting processes have been tested and certified together. This ensures that functionality, quality, and fire protection are maintained. Contact us and we’ll help you find the right solution for your project.
Health, Environment & Safety
BURNBLOCK® fire protection consists of naturally based ingredients, is non-toxic, and is designed to be biodegradable along with the wood.
The products are also CE marked, which means that they meet European Union requirements in areas such as the environment, health, and safety.
Cradle to cradle
Burnblock® Fire Retardant Powder has been awarded the Cradle to Cradle Certified® Material Health Certificate™ Gold. This certification means that the material has been evaluated according to strict criteria for material health and safe use in products.
The certification focuses on the chemical content of materials and their impact on people and the environment throughout the product's life cycle.
Process
Our fire protection impregnation is carefully designed and ensures both high quality and effectiveness. The result is fire-protected wood that meets the high fire performance requirements of modern construction projects.
The fire protection is applied using high-tech equipment that ensures even and deep impregnation of the wood to guarantee optimal protection.
Our process is not only effective but also tailored to meet our customers' unique needs and ensure that the projects are protected against fire in the best possible way.
Fire classes
Fire classes are used to classify materials and construction products based on their fire safety. The classes cover various properties. Fire resistance classes range from A to F, where A represents materials with the highest fire safety and F those with the lowest fire safety. As a complement to the A-F scale, there are also s1-s3 and d0-d2, which classify the reaction to fire.
Classification is crucial to ensuring safety in buildings and serves as a guide when selecting materials. Sveden Trä's products with a thickness of 15-42 mm are available in the highest fire class for wood products, B-s1, d0. From 43 mm and above, the wood product is classified in fire class B-s2, d0.
What do Sveden Trä's fire classes mean?
B- s1, d0: Sveden Wood's products with a thickness between 15-42 mm can be obtained with fire class B-s1,d0. This fire class means that the wood product does not contribute to the development of fire and emits a very limited amount of fire gases and no burning droplets or particles are emitted from the product.
B-s2, d0: For products with a thickness from 43 mm and up, fire class B-s2, d0 is achieved, which, in contrast to the above-mentioned classification, means that the product emits a limited amount of combustion gases. Like the classification above, the product does not contribute to fire, and no burning droplets or particles are emitted from the product.
| Euroclass | Product example | |
| A1 | Non-combustible materials, incombustible. | Stone, concrete, steel |
| A2 | Non-combustible material. No noticeable contribution to fire. | Gypsum boards with thin paper, mineral wool |
| B | Very little contribution to fire. | Gypsum boards with thick paper, highest class of fire-protected wood |
| C | Risks becoming ignited after a certain time. Little contribution to fire. | Wallpaper on gypsum board, lower class of fire-protected wood |
| D | Risks becoming ignited, intermediate contribution to fire. | Wood and wood-based panels |
| E | Provides very rapid ignition, high contribution to fire. | Certain synthetic materials |
| F | Combustible material. Large contribution to fire development. | Does not meet class E |
| Fire gas | |
| s1 | Releases a very limited amount of fire gases |
| s2 | Releases a limited amount of fire gases |
| s3 | No requirement for limited production of fire gases |
| Burning droplets | |
| d0 | Burning droplets or particles are not emitted from the building component |
| d1 | Burning droplets or particles are emitted in limited quantities |
| d2 | No requirement for limiting burning droplets and particles |
