Fire protection
With a focus on sustainability, Sveden Trä, together with burnblock, offers an environmentally friendly fire protection as a safe and effective solution.
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 proudly present the possibility of supplying environmentally friendly fire protection. Burnblock prevents oxygen from reaching the treated object – and without oxygen: no fire.
Fire protection for the future
Our fire impregnation with Burnblock is highly effective, non-toxic and consists only of natural ingredients that are combined in a patented formula. Burnblock is an invisible treatment that does not leave any oily or spotty surface, nor any other visible trace. This means that the raw material can easily be combined with post-treatment, such as painting. We will help you find the best solution for your object.
Health, Environment & Safety
The fire protection from BURNBLOCK® consists of 100% natural substances and is non-toxic and 100% biodegradable.
The products are also CE-marked, which means that the products meet the European Union's requirements regarding, among other things, the environment, health and safety.
Cradle to cradle
Burnblock® Fire Retardant Powder is certified according to Cradle to Cradle Gold.
The Cradle to Cradle certification broadens the company's commitment beyond material sustainability. Cradle to Cradle includes aspects such as safety and environment, consumption of water and energy, and commitment to social justice.
Process
Our fire protection impregnation is carefully designed and ensures both high quality and efficiency.
The fire protection is applied through high-tech equipment that ensures that the wood is impregnated evenly and completely 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 building products based on their fire safety. The classes cover different properties. Fire classes for fire resistance 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 d1-d3, which classify the reaction to fire exposure.
The classification is crucial for 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 up, the wood products are classified within 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 |
