No flash in the pan, but sustainable heating: The new IDEAL CLASSIC ÖKO ST surface heating
IDEAL CLASSIC ÖKO ST is a sustainable and resource-saving surface heating system for new buildings and renovations that meets the highest energy efficiency requirements.

Straw as an insulation material carrier | Resource conservation and energy efficiency
Whether new construction or renovation of an existing building - with IDEAL CLASSIC ÖKO ST, a surface heating system is now available that fully meets the requirements of modern builders in terms of sustainability, resource conservation and energy efficiency. IDEAL CLASSIC dry construction system, which has been successful for decades, is being expanded to include a further future-oriented solution.
Insulation carrier made from plant-based raw materials
The innovation with IDEAL CLASSIC ÖKO ST lies in the insulation material. A special process made it possible to use straw as an insulation material with outstanding properties. As a by-product of agriculture, straw is a plant-based and rapidly renewable raw material. The material is available in large quantities, so that the use of IDEAL CLASSIC ÖKO ST does not result in any restrictions in other areas (e.g. competition with food). In short: straw is characterized by maximum sustainability in every respect. All materials are also separable and recyclable.
Ecological surface heating and cooling
With IDEAL CLASSIC ÖKO ST, surface heating and cooling for floors, walls and ceilings can be achieved without much effort. Due to the low coverage (it does not require a thick screed), the system allows for quick heating and cooling, thus providing feel-good warmth at the push of a button.
IDEAL CLASSIC ÖKO ST is a sustainable surface heating system and meets the highest standards with its technical values:
- High compressive strength of >150 kPa
- Good thermal conductivity of the insulation material of 0.055 W/mK
- Fire class E
- Impact sound reducing properties
Minimum installation height and dry installation
Like all IDEAL systems CLASSIC ÖKO ST is characterized by a very low installation height and is therefore ideal for energy-efficient renovation in old buildings. The dry installation also speaks for this: highly efficient surface heating can be completed within a very short time and with minimal structural intervention. COMPACT FLOOR are suitable as dry screeds , thanks to the innovative heat-conducting layers that heat the room with a minimum heating water temperature and thus minimize energy consumption.
- Maximum sustainability out of responsibility for future generations
- Insulation material made from rapidly renewable raw materials
- Comfortable and energy-saving thanks to quick control
- Solutions for new buildings and renovations with low construction heights
- Short construction times thanks to dry installation
