Description

The Isotex HDIII 30/7 formwork block is used to create external load-bearing walls. Inside the formwork, there is an insulating insert in eco-sustainable EPS, made of Neopor® BMBcert by BASF up to 100% recycled (Biomass). It has a thickness of 30 cm and a continuous insulating insert of 7 cm, with a concrete cast thickness of 15 cm, as per technical standards. Thermal transmittance U=0.34 W/m²K. The block has the exclusive features of the entire Isotex product range. The wood is mineralised with a natural mineral that makes it inert, therefore resistant to fire (REI120), parasites and atmospheric agents. Reaction to fire B,s1-d0. Excellent facade fire behaviour (Lepir2 Test).

Sustainability certification:

Green building ANAB/ICEA
Environmental Declaration of Type III Products (EPD/FDES)
ReMade in Italy certification for Isotex Total Green (100% recycled) and Isotex Green (15% recycled) insulation elements, consisting of Neopor® BMBcert from BASF.

* The calculation of thermal transmittance has been performed according to the criteria of standards UNI 10355 and UNI EN ISO 6946, using a three-dimensional finite element calculation application validated according to EN 10211/1 and on the basis of thermal conductivity data obtained from experimental evidence.
**Indicative two-dimensional calculation according to standards UNI-TS 13788, UNI 10355 and UNI 10351.
*** Note: The test certificates can be requested from ISOTEX or consulted on the WEBSITE. The tests were field tests in which the data was elaborated according to the indications provided by technical standards UNI EN ISO 140 and UNI EN ISO 717.
****Tests performed in the laboratory according to standards UNI EN ISO 140-3:2006 and UNI EN ISO 717-1:2007.
*****Tests performed in the laboratory according to standards UNI EN ISO 10140-2:2010 and UNI EN ISO 717-1:2007.

In reference to the type of material purchased, the company will provide EC Declaration of Performance (DOP).
