Low-flammability, non-combustible wood fibre insulation board
Gutex Pyroresist wall is the first wood-fibre insulation board that is both flame-retardant and non-combustible, for use in multi-storey residential buildings up to building class 4/5 and in urban densification. Thanks to its C-s1, d0 building material classification in accordance with DIN EN 13501-1 and its non-glowing property (DIN EN 16733), the environmentally-friendly insulation slows down the spread of flames in the event of a fire, as well as their spread to neighbouring floors and buildings. Even under fire conditions, it gives off virtually no smoke and delays the progress of the fire even more effectively than is usual for wood-fibre insulation boards. It also prevents fires from smouldering after an open fire has been extinguished.
- Low-flammability, non-incendive wood fibre insulation board -
safe fire protection up to building class 5 - Effective protection of building structures with better fire containment and low smoke development, no flaming drops
- Excellent heat and sound insulation for comfortable living
Nominal value of thermal conductivity λD
0,044 W/mK
Design value of thermal conductivity λB
0,046 W/mK
Product details
Gutex Pyroresist wall: durable, compliant with standards and the only "non-incandescent" wood fibre insulation.
Pyroresist wall not only impresses with the positive properties of wood-fibre insulation, but also offers other, in part unique, advantages: it is assessed in accordance with the harmonised European product standard DIN EN 13171, which governs the requirements for the thermal, mechanical and physical properties of wood-fibre insulation. For Gutex's specialist partners, this assessment offers planning and implementation security, as standardised properties such as compressive strength and thermal insulation are reliably tested. Building owners benefit from the guaranteed quality and longevity of a standardised product - two important contributions to energy-efficient living of stable value. Thanks to its relatively high gross density, Pyroresist wall can also improve the acoustic insulation of building components, which makes it predestined, in addition to its properties, for use in the construction industry.
- Quality tested to DIN EN 13171 for planning and installation safety
- Excellent sound insulation thanks to a high density of 190 kg/m³.
- Durability thanks to the use of PEFC-certified timber and proven harmlessness from the point of view of construction biology (natureplus certified)
Effective fire protection and sustainable building physics
The Pyroresist wall, which has won innovation awards, has been proven to improve fire protection in building structures, which is particularly beneficial for building elements with wood fibre insulation. In the case of ventilated facades, the recyclable panel limits the chimney effect thanks to its intumescent properties: when exposed to fire, it swells and thus reduces or seals the rear ventilation gap. Thanks to its hydrophobic treatment, the panel is water-repellent and resistant to outdoor weather conditions. At the same time, it is windproof and open to diffusion, which promotes a healthy indoor climate. Pyroresist wall also minimises thermal bridges and offers very good thermal protection and high heat storage capacity. With its homogeneous gross density profile, it is impact-resistant, dimensionally accurate and as easy to work with and fix as any other wood fibre insulation panel. From a building physics perspective, it also fits into the group of wood fibre insulation products and is therefore ideal for timber construction.
- limit the chimney effect on ventilated facades and
enhanced fire protection for buildings, ideal for building elements with wood-fibre compartment insulation - Hydrophobic, windtight and diffusion-open for long-term building physics safety and a healthy indoor climate
- Recyclable, impact-resistant insulation board with a homogeneous gross density profile for versatile applications with high fire protection requirements - particularly in timber construction
Ingredients
- Untreated fir and spruce wood
- Inorganic mineral-based flame retardant
- Paraffin to render hydrophobic
- PUR resin as a moisture-resistant binder
Pyroresist wall: impact-resistant, precisely dimensioned and installed as usual
Pyroresist wall can be processed in the same way as conventional compression-resistant wood fibre insulation boards: it can be cut, drilled and milled using standard tools. For mounting on wooden frames or solid wood elements, the usual fasteners such as stainless steel wide-back staples or washer fasteners are suitable.
The low-flammability, non-combustible panel can also be plastered without any problems in the field of ITE applications. The approval procedure for integration in Thermowall WDVS is currently underway.
