wood fibre:
nature´s high-tech insulation material

Insulation and climate all-rounders

STEICO wood fibre insulation materials are true all-rounders. They protect against cold, heat, noise, and moisture. They are also permeable and help make living spaces healthy. In addition, they provide double climate protection – as they store CO2 and reduce CO2 emissions by conserving heating energy.

How STEICO wood fibre insulation materials are manufactured

Two processes are used to manufacture wood fibre insulation materials - the wet process and the dry process. In both processes, fresh coniferous wood is broken down by steam and mechanical treatment into individual fibres, which are then further processed.

The wet process

In the wet process, the soaked fibres are formed into panels. Then the panels are calibrated in thickness and dried as whole pieces. The clever bit: in the wet process, the wood's own natural lignin binds the panels. This means that no external adhesives are required, making wet-process insulation boards very eco-friendly and beneficial or your living environment. 

The dry process

In the dry process, the fibres are dried before panel formation. A small amount of binder is applied to the fibres, which are then formed into panels. The clever bit: dry-processed wood fibre insulation panels are lighter and can be produced in greater thicknesses. That is why they are often used to insulate the building envelope, e.g., for above-rafter insulation or facade insulation.

Flexible insulation batts and air-injected insulation

Depending on the technology, fibres for air-injected insulation, flexible batts or solid insulation panels can be produced in the dry process.

Heat has no chance of getting in

Thanks to its high heat storage capacity, the wood fibre insulation can buffer summer heat over a period of several hours. Most heat does not even get into the living space, overheating is delayed and reduced in equal measure. In the cooler evening and night hours, the stored heat can then radiate outwards again and escape.

Compared to many synthetic insulation materials, wood fibre insulation materials are much less likely to reach temperature levels that cause discomfort. With STEICO wood fibre insulation materials, heat peaks are reduced by 25 to 33 per cent (expert analysis by Prof. Hauser). The result: with wood fibre insulation materials, we feel less discomfort on hot summer days. They regulate temperature in a natural way, increase well-being and are also good for the environment.

Rainproof sarking boards

STEICO sarking boards and wall panels are hydrophobic, i.e., water-repellent. Rainwater’s surface tension cannot break through sarking boards like STEICOuniversal dry but runs off the surface. The panels are provided with a tightly closing, all-round tongue and groove profile and thus offer a rainproofing function and serve as temporary covering.

MORE

Suitable as temporary covering for up to 12 weeks

STEICO sarking boards can be laid directly on the rafters without battens and instantly provide robust weather protection. Thanks to the special tongue and groove profile, they seal tightly and can be exposed to the elements on roof slopes over 16° - without any additional roof membrane. They fulfil three functions in one fell swoop:

• a windproof layer

• a secondary water removal layer

• additional insulation

As sarking boards, they can be used as temporary covering for several weeks

Reduce constructive thermal bridges

Laying above the rafters effectively reduces structural thermal bridges, even with thin panels. The top of the rafters is insulated and thus warmer, significantly reducing the risk of condensation.

Additional insulation above the rafters

The rafters of old building roofs are often small, but between rafter insulation alone does not provide thermal protection that meets modern standards. With insulation above the rafters, the roof can be insulated in a future-proof way without taking up valuable living space under the roof. At the same time, the sound insulation is noticeably improved.

The Keymark certification stands for the high quality of the STEICO range. The uniform European certification mark for standardised products documents the compliance of products with European norms and quality standards.

The contribution of STEICO insulation materials to a healthy home

  • Checked and tested

  • Diffusion-open materials

  • Excellent heat protection

  • Optimum indoor humidity

  • Excellent noise protection

  • STEICO insulation materials are regularly and independently inspected and tested. The IBR seal (Institut für Baubiologie Rosenheim) is proof that only harmless ingredients are used.

  • You know the principle from your outdoor jacket: STEICO insulation materials are "breathable", i.e. vapour-permeable. They offer active moisture management: if moisture gets into the insulation layer, it will dry off to the outside. This intelligent moisture management keeps the construction permanently dry. The ideal protection against moisture in the construction and its consequences such as mould and structural damage.

  • STEICO insulation is not only effective in winter, but also in summer. Thanks to the excellent heat protection, STEICO wood fibre insulation materials make a significant contribution to cooler rooms on the hot days and thus support a restful sleep.

  • STEICO wood fibre insulating materials are hygroscopic, i.e. they can absorb and release air moisture. When used indoors (e.g. in floor constructions or drywall), they help regulate humidity by buffering moisture at the peaks and releasing it again when the air in the room is dry.

  • Stressful background noises such as traffic or construction sites in the neighbourhood reduce the feeling of well-being at home – yet quiet is important for our health.

    STEICO products combine high raw density with excellent insulation values in a special way and thus support energy efficiency and noise protection in equal measure. Due to their high density and porous structure, STEICO wood fibre insulating materials promote sound absorption and thus offer excellent noise protection.

Certified fire protection

The Fraunhofer Institute for Wood Research - one of Germany's most-renowned research institutes - has examined and determined the fire behaviour of insulation materials made from renewable raw materials and rigid foam:

“Rigid foams burn extremely quickly, with very strong dark smoke formation, and melt and drip during burning. The investigated natural insulation materials (including STEICO wood fibre insulation materials) also burn, but relatively slowly, with little smoke development and do not drip while burning. The fire behaviour of natural insulation materials is therefore significantly more advantageous than that of rigid foams, especially in the early phases of a fire, and is predictable.”

High raw density = excellent sound insulation

As a general rule, the heavier a component, the less noise can penetrate it. When it comes to sound insulation that means that the weight (mass) of the building component - i.e. the bulk density of the building material - is what counts, along with other aspects. The component thickness is not necessarily decisive. STEICO wood fibre insulating materials are characterised by a particularly high raw density and thus support effective noise protection.

STEICO products uniquely combine high bulk density with low thermal conductivity and thus equally support energy efficiency and noise protection.
