FIRE RESISTANCE FOR WOOD TEKNOSAFE 2407 fire retardant coating offers the highest fire resistance classification, B-s1, d0, on exterior timber cladding.

With suitable top coats, Teknosafe 2407 combines outstanding fire resistance with long-term durability and maintenance intervals of up to 10 years

Fire-retardant exterior cladding in a new building in Vantaa, Finland.

Fire-retardant and weather resistant exterior cladding is attracting growing interest in Scandinavia. New building regulations, such as Finland’s National Building Code (E1), have improved the competitiveness of wood as a construction material and the use of timber, particularly on high rise buildings, is now growing significantly.

An important factor in this growth has been the introduction of Teknos’ new fire-retardant coating TEKNOSAFE 2407, an intumescent primer, factory applied over TEKNOL AQUA 1410 wood preservative and topcoated with Aquatop opaque finishes.

Independent testing The Teknos coating system was tested at SP Trätek in Sweden, over fine sawn and planed spruce, and classified according to EN 13501-1 fire resistance standard EN 13823.

Cost-effective fire protection A development of two story flats located in Vantaa is typical of Finnish projects in Finland using the TEKNOSAFE 2407 fire-retardant system. Since the developer had planning consent to build a third storey the exterior had to be fire-protected.

Under the new fire regulations, fire protection of three to eight-storey buildings with exterior wooden cladding can be achieved in three ways: •

Using a fire-retardant coating system

•

Fitting the exterior cladding with sprinklers

•

Installing structural fire protection.

With structural fire protection, the wood is encased and the result, though effective, is not particularly architecturally pleasing!

Similarly, it is not always desirable to have sprinkler systems visible in wood structures... and such systems can be expensive.

Fire retardant coating systems therefore often offer the ideal balance between aesthetics, cost and performance.

On the Vantaa project, fire protecting the exterior cladding with TEKNOSAFE 2407 cost €35,000 compared with a sprinkler system costing €80,000.

With interest growing throughout Europe in the performance and construction speed of multi storey wooden buildings, Teknos expects to see significant growth in sales of TEKNOSAFE 2407 coating systems on an ever wider range of timber substrates.

Understanding Fire Testing SBI fire-class test method The Single Burning Item (SBI) test, classifies all building products,­except floorings, into fire classes A2, B, C and D by assessing their reaction to fire when exposed to a flame from a specified fire source (propane gas burner).

In addition to the it’s fire class, the material is classified by smoke production (s1 - s3; where 1 has least smoke generation); and the presence of flaming droplets (d0 - d2; where d0 signifies not flaming droplets or particles).

The flame is directed at the bottom edge of the tested specimen. Heat release and combustion gases are measured and physical changes are classified by visual observation.

Fire classification (E1 National Building Code of Finland, Fire safety of buildings, Regulations and guidelines 2011) •

Buildings are divided into three fire classes: P1, P2 and P3 (P1 being the most demanding).

•

The classification of building products is denoted by the following markings: A1, A2, B, C, D, E, and F.

•

Building products are divided into classes, on the basis of how they contribute to ignition and the spread of fire, smoke production and the generation of flaming droplets.

•

Smoke production and the generation of flaming droplets are expressed by the additional markings ‘s’ and ‘d’. The classification for smoke production is s1, s2 and s3 and that for flaming droplets d0, d1 and d2.

Schertler-Alge: Advanced window production Schertler-Alge GmbH, based in Lauterach, Austria, is one of the region’s leading construction firms. The company has manufactured windows and doors for over 50 years, and in 2010 invested €4.5 million in a new plant with computercontrolled systems for producing wood and wood/aluminium windows, and high-quality, custom-made interior and exterior doors.

Premium surface quality Schertler-Alge puts top priority on high-quality coatings.

“Traditionally our windows and doors were painted with Teknos systems and we were very pleased with the results,” says Thorsten Hölzlsauer, the departmental head of window and door production at Schertler-Alge. “That’s why we’re using Teknos products in our new facility. The finished surfaces are exactly the way we want, and Teknos provided excellent support and technical advice when setting up our facility.”

An important factor in choosing their current Teknos system was the elimination of intermediate sanding – only an in process optical inspection is now carried out.

Architects won over by quality

Water based solution for interior wood TEKNOCOAT AQUA 1330 offers a water based alternative to traditional acid curing and pre cat lacquers, matching, and in most cases outperforming, their resistance to water, grease and stains.

Available in colourless and custom shades, TEKNOCOAT AQUA 1330 can be applied by brush or spray to both softwoods and hardwoods, and can be used in a dual-layer system as both primer and topcoat.

As a water-based product, TEKNOCOAT AQUA 1330 meets modern requirements in terms of environmental impact and safety whilst providing a high quality, durable surface, with gloss levels between 10% and 50%.

Durability against household chemicals, liquids and heat are accordance with EN 12720/12721/12722 and TEKNOCOAT AQUA 1330 also meets Class R2 of the IOS-MAT-0066 IKEA specification.

New warning label regulations The ‘CLP directive’, which implements UN recommendations for global classification and labelling of chemicals, is currently being introduced in Europe.

The changes will see the old orange warning symbols replaced by new, international pictograms on a white background in a red triangular frame.

Paints and varnishes have until June 2015 to comply, so over the next three years, Teknos will progressively introduce the new labelling scheme on its paint packaging. Safety Data Sheets will also be progressively revised to include both the new symbols and additional information required by the REACH regulations.

The latest Safety Data Sheets are available on our website: www.teknos.co.uk
