Passive fire protection
A passive fire protection is an important preventive fire protection. TBT has many years of experience in passive fire protection, from design, fire sealing, painting, insulation and sectioning. Here you get help with all kinds of passive fire protection measures in all types of buildings, infrastructure, tunnels. The earlier in the construction project TBT comes in, the faster and more cost-effective your fire protection can be secured.
Services
For example, TBT performs:
- Fire seal
- Fire protection painting
- Fire insulation
- Fire sectioning
- Fire protection
- Fire clothing
- Brandputs
- Fire impregnation
Counseling and education
Knowledge of both risks and effective protection measures is an essential part of your fire protection. We offer:
- Inventory of existing fire protection
- Advice on appropriate measures
- Education (See our course program)
- Fire protection descriptions
Everything in passive fire protection
Fire seal
TBT performs fire sealing in floors and walls. Fire seal prevents fire and flue gas from spreading, keeps the building’s fire cells tight despite installation penetrations / pipe penetrations.
Inventory
TBT can inspect the existing properties to prevent future fire hazards. Depending on your specific needs and requirements we can:
- Evaluate the properties at hand to get a complete inventory of the current fire protection situation
- Check all parts of the existing fire protection and, if needed, suggest proper measures
- Carry out any passive fire protection measures required
- Document and present all measures taken
- Set up or revise existing routines for systematic fire protection (in Sweden known as SBA).
Fire coating
Structural steel, concrete, wood, textiles and other surface layers
The fire resistance of a structural construction is classified as R30, R60, R90, etc. The letter R stands for Resistance and the number represents the number of minutes that, for example, the construction would stay intact and carry the load in case of a fire.
The amount of fire safety coating applied to meet the prescribed fire protection classification depends on several factors: type of building (one, two or multiple stories) which defines the fire resistance classification; the static utilization of the construction load in the case of a fire; and F/A = the ratio between the surface exposed to fire and the sectional area of the steel profile at hand.
Based on these parameters, the amount of required coating is calculated.
We are authorized to perform fire safety coating with Envirograf HWO1 and HWO2, which provides EI class wood. It will also meet demands for K210 – Bs1do (inflammable surface).
Fire insulation
Steel, concrete, tunnels and structural wood constructions
As an alternative to structural fire coating you may use stone wool or various types of clad sheets (with gypsum, calcium silicate, etc.) for fire insulation.
Dimensioning of fire retardant materials is based on the same parameters as dimensioning of fire coating, i.e. type of building, static utilization, fire curves and F/A.
Fire protection of a surface layer is categorized according to various classifications, for example European Standard B-s1, dO (formerly surface layer class 1), inflammable surface. Optimizing the surface layer of a fire compartment is imperative to control the generation and dispersion of smoke during the early phase of fire.
Fire safety sectioning
Täby BrandskyddsTeknik offers complete installation of fire and smoke curtains, fire doors and fire safety sectioning using fire protection cloth.
Materials for passive fire protection
We use TBT Firestop® fire protection material, for an efficient and reliable fire seal. You will also find these in our web shop.
