Kronotherm DF 20 is a stable and pressure-resistant wood fibre insulation material in accordance with DIN EN 13 171 and German technical approval Z-23.15-1581.

Kronotherm DF 20 has a density of approx. 100 kg/m³ and a compression strength of more than 20 kPa at 10% compression. The panel is thus far superior in terms of resistance to pressure than other insulating panels with the same density.

The flat smooth surface and low tolerances makes Kronotherm DF 20 particularly suitable for use as a heat insulation panel under stone floors. This is also confirmed by the approved area of use DEO, _dm as per DIN V 4108-10.

The predestined use is as on-roof insulation using double threaded bolts. In terms of compression strength Kronotherm DF 20 corresponds to standard multi-layered adhesive wood fibre panels manufactured by the wet procedure for insulation purposes.
Kronotherm DF 20 represents, together with Kronotherm DP (roof panel), an economical opportunity to install on-rafter insulation in new buildings and in terms of portfolio modernisation.

Kronotherm DF 20 is manufactured in an environmentally-friendly way and with very little use of energy whereby the CO₂ cycle is virtually closed over the entire life of the product.

Kronotherm DF 20 stands out especially due to its very pleasant touch, ease of processing, is kind to the skin, open diffusion and excellent heat accumulation capacity.

The high sorption capacity of natural wood fibres means that Kronotherm DF 20 makes a crucial contribution to a pleasant atmospheric environment. Kronotherm DF 20 can absorb and then release again large quantities of moisture without changing its structure and without any deterioration in its insulation characteristics.

Technical Data
Manufacture and monitoring in accordance with DIN EN 13 171 and German technical approval Z-23.15-1581

Processing

·  Cut with electric crosscut saw, circular saw and band saw

·  Wear a dust mask when machine cutting

·  If being used as on-rafter insulation, lay on dry, load-distributing underfloor

·  Attach non-slip boards near verge flashing and eaves to hold in position

·  Avoid cross joints and make sure they adjoin closely

·  Fit a water-bearing sublevel immediately after fitting

·  Double-threaded bolts are required for attachment

·  The information sheet for Würth ASSY Isotop double-threaded bolts can be 
   downloaded under "Infomaterial – Technical Information".

Storage, transportation

·  Stand the package on a secure surface when cutting the film packaging in order 
   to avoid accidents

·  Store and assemble in a dry atmosphere

·  Do not stack pallets on top of one another
