How is THERMOFLOC installed?

Depending on the area of application, THERMOFLOC is installed either manually or using specialist blowing machines.


THERMOFLOC is a certified, high-quality insulation material made of organic cellulose fibers.

Where is THERMOFLOC used?

THERMOFLOC cellulose material is used for the insulation of floors, walls, ceilings and roofs.

Who carries out the installation? Is it possible to install THERMOFLOC on your own?

The THERMOFLOC Blown-in insulation is installed by means of specially equipped THERMOBLOW blowing machines operated by certified workers. The insulation is pumped into hoses under air pressure and transported further into the hollow spaces of the building components, where it is compressed in accordance with the material handling instructions to produce an uninterrupted, complete and insulation layer that is open to diffusion.

The THERMOFLOC Loose-Fill is processed by hand and used exclusively as non-pressure resistant insulation at the horizontal level (ceiling on the top storey, between joists in a wood-joist floor construction).

Can THERMOFLOC be installed without machines?

THERMOFLOC Loose-fill is processed by hand. The blow-in insulation material is exclusively installed by means of a specially equipped blowing machine into the hollow spaces.

What additives does THERMOFLOC contain?

For fire prevention, minerals are added.

What is the product’s fire classification?

THERMOFLOC is classified as B-s2,d0 (difficult to ignite).

Who can provide me with an offer?

For Blown-in Insulation please contact us directly for a quote. THERMOFLOC Loose-fill is available through a wide network of merchants, please visit our “where to buy” page for details of our distributors.

What is THERMOFLOC’s thermal performance in comparison with other insulation products?

THERMOFLOC has the same insulation properties as other standard insulating materials made of mineral fibers or EPS products. In addition, it is an organic insulation and as such is highly breathable.

What raw materials are used for the manufacture of THERMOFLOC?

THERMOFLOC is made of waste paper and mineral additives providing fire protection.

What “seals of approval” does THERMOFLOC carry?

The outstanding quality features of our cellulose insulation have been recognized by European Technical Approval, ISO certification and the awarding of the Natureplus quality label.

What is Natureplus?

Natureplus is the international quality seal for high quality, sustainable building materials, building products and furnishings. Products which carry this label pose no danger to health, are produced in an environmentally-friendly manner and are tested for their functionality. A comprehensive and stringent testing process, according to the strictest of criteria, ensures that these products fulfill these high standards.

The Natureplus quality seal is only issued to building and accommodation-related products which are comprised of a minimum of 85% of renewable raw materials or mineral based materials which are almost unlimited in their availability. This is intended to underline the sustainable availability of these products and thereby their applicability for the future. Independent of the Natureplus quality seal, the product must also display a declaration of the contents in order to enable an accurate classification of the products by the consumer.

What U-value can be achieved with a THERMOFLOC insulated construction?

With a Lambda value of 0.039, THERMOFLOC achieves the same U-values as other conventional insulation materials. The U-value will depend on insulation thickness. Please contact us if you require U-value calculations.

How does its thermal performance compare to that of mineral wool?

As well as offering at least the same level of insulation as mineral-fiber based products, THERMOFLOC features additional advantages with regard to breathability, building health and sustainability.

Can Thermofloc be used in brick and block cavity walling?

THERMOFLOC cannot be used for cavity wall insulation.
