ThermoWhite® insulation systems at a glance
The CE-certified ThermoWhite® loose-fill insulation balances out pipe runs seamlessly and reduces impact sound by up to 32 dB. Thanks to PLC-controlled MixMobil technology, 150-meter hose routing, and the "Speed Up" component, the highly load-bearing floor build-up is ready for covering after just 12 to 24 hours.
Why is ThermoWhite® loose-fill insulation ideal for floor construction? The CE-certified ThermoWhite® WD series eliminates thermal and sound bridges completely. The seamless insulation system adapts precisely to complex pipe layouts and variable installation heights on the structural slab.
Compared directly with conventional board systems, the loose-fill solution offers guaranteed impact sound improvement of up to 32 dB. It is suitable as a base for every application, from attic floors to pool backfills.
How does the MixMobil principle accelerate construction sites? The PLC-controlled MixMobil system guarantees absolute recipe consistency of WD products directly on site. Clean hose routing allows the material to be pumped flexibly over distances of up to 150 meters.
By adding the "Speed Up" component, the insulation system is ready for covering after 12 to 24 hours. The system provides architects, planners, and screed installers with high execution quality while drastically reducing setup times.

The advantages of the ThermoWhite® system
The ThermoWhite® system delivers tested insulation performance, sustainable materials, and quality made in Austria.
Certificates & verified quality
ThermoWhite® products comply with strict European quality standards.
The documents describe the tested system properties. We will clarify which evidence and installation conditions apply to your project in Denmark.
Evidence for your project in Denmark
Product version, system assembly and application conditions belong together. We help you identify the relevant documents.
Product-specific evidence
ETAs, declarations of performance and data sheets apply to the documented product version and installation conditions.
Controlled installation
The appropriate mixture, installation thickness and subsequent layers form part of the planned system assembly.
Danish environmental declaration
EPD MD-23094-DA_rev1 documents WD70, WD100 and WD130. Revised 5 April 2024, with stated validity until 29 September 2028.
Does every document apply to every product?
No. Product identity, version and installation conditions must match the document. The Danish EPD is not a blanket approval of the entire catalogue.
Which values apply to my floor assembly?
The appropriate current product version, planned thickness and complete system assembly determine the applicable values. Differences in older documents require technical clarification before any commitment.
Is funding guaranteed?
There is no blanket funding commitment. Market-specific and project-specific requirements must be checked separately.
