Thermal insulation by THERMOFLOC – natural cellulose insulation
THERMOFLOC is a natureplus®-certified cellulose insulation material made from carefully selected recycled newspaper. Its premium quality has been independently confirmed through European technical approval (ETA). THERMOFLOC provides high-performance thermal insulation, is produced with low environmental impact, and offers significant advantages during installation.
Thanks to the innovative THERMOBLOW blowing technology, seamless insulation can be installed in roofs, floors and walls without cutting waste. This results in lower installation costs, faster application times and superior airtightness compared to traditional insulation systems.
For more than 20 years, THERMOFLOC has been the trusted choice for ecological, durable and energy-efficient insulation in new builds and renovations.

Intelligent insulation with system
THERMOFLOC blown-in insulation: efficient, cost-effective, versatile
The blown-in insulation material made from recycled newspaper reduces energy costs for heating in winter and for air conditioning in summer, and ensures a comfortable indoor climate in every season.
THERMOFLOC – insulating floor filling material – as non-load-bearing insulation
The insulating floor filling material is used as non-load-bearing floor insulation and provides high thermal insulation and optimal sound reduction.
THERMOFLOC insulation pellets as a load-bearing insulation layer
THERMOFLOC insulation pellets improve the insulation performance of concrete ceilings as well as timber beam floors and also provide excellent sound insulation values.
Blow-in technology – seamless, free from harmful substances and breathable
Using THERMOBLOW blow-in technology, the client benefits from a seamless insulation layer that is free of thermal bridges.
VAPOUR BARRIER – protection for your thermal insulation
The vapour control and airtight membrane protects structures against moisture and can be used for interior wall and roof constructions.
Roof sheathing membrane – optimum protection against rain and wind
The THERMOFLOC roof sheathing membrane protects the structure against driving rain and thereby prevents moisture from penetrating the roof or wall construction.
THERMOBAG system
The THERMOFLOC THERMOBAG system offers the possibility to insulate roofs afterwards in a clean and cost-effective way.
TAPE – indispensable in every thermal insulation system
THERMOFLOC adhesive tapes are specially tailored to our products and together with them form a breathable and efficient THERMOFLOC thermal insulation system.
THERMOFLOC quality certificates

Roof insulation
Besides the façade, the roof is the largest surface where heat losses can be reduced. In an uninsulated roof, heat losses can reach up to 30 percent.
Floor & ceiling insulation
Heat always rises upwards. It escapes almost unhindered when ceilings are located beneath unheated or rarely heated rooms, or directly under flat roofs that are not sufficiently insulated.
Façade insulation
The best moment to consider thermal insulation of the external wall is an upcoming façade renovation or a planned replacement of the windows.
Insulation system from basement to roof – an overview of the application areas
THERMOFLOC cellulose insulation material is installed by certified companies throughout Europe using specially equipped THERMOBLOW blow-in machines. The insulation material is transported under air pressure into the cavities of the building components and compressed in accordance with the installation guidelines, creating a seamless, homogeneous and breathable insulation layer. Cutting waste is virtually eliminated, as only the exact amount of insulation required for the specific construction is blown into the building element. All corners and gaps, even the smallest cavities, are filled to a full 100%.
THERMOFLOC insulation materials for clients & homeowners
More and more clients and homeowners across Europe are fully choosing THERMOFLOC cellulose insulation material.
Solutions for insulation challenges for architects & craftsmen
