Automation of insulation work

In prefabrication, time is money. Modern blow-in stations and automated large-scale systems enable almost complete automation of insulation work using all standard blow-in insulation materials.

Seamless precision: The loose material is introduced into the cavities in a controlled manner and compacts there to form a precisely fitting, settlement-proof insulation layer. This results in uniform insulation without voids or gaps.

No waste: As the insulation material is introduced in loose form, there is no waste and no need for the laborious disposal of off-cuts. This maximises material efficiency and conserves resources.

Superior building physics right from the factory

Building components that are pre-insulated with cellulose at the factory offer key benefits to the end customer:

Heat protection included: Thanks to seamless blowing-in and the high density specific to the material – particularly in the case of cellulose insulation – the wall and roof elements offer excellent thermal protection in summer.

Optimal sound insulation: The joint-free blowing process ensures high flow resistance within the component. The result is excellent sound insulation and a noticeable sense of peace and quiet within your own four walls – an important selling point for prefabricated house suppliers.

Quality assurance through systems engineering

Controlled conditions prevail in the production hall. ISOCELL offers perfectly coordinated system components for this purpose, comprising high-performance blowing machines, special hoses, nozzles and innovative measurement technology.

Logging: Modern, software-supported blowing systems can precisely document the quantity and bulk density applied per compartment. This greatly simplifies comprehensive quality assurance and provides certainty for the timber construction company.

Expert tip from ISOCELL

“In modern timber construction, it is not a question of committing to a single insulation material, but of having the best solution in terms of both cost-effectiveness and building physics for every project. Our machinery is therefore deliberately designed as an open system. Combined with the right technical knowledge from our training courses, we give companies the freedom and confidence to respond flexibly to every customer requirement – efficiently, flawlessly and with a future-proof approach.” – Bernhard Hemetsberger, Head of ISOCELL Blow-in Technology.

Maximum flexibility: one system for all standard blow-in insulation materials

A key feature of ISOCELL’s machinery technology is its manufacturer-independent flexibility and high adaptability to the specific requirements of each operation:

Scalable automation: ISOCELL offers blow-in systems with varying degrees of automation. The range extends from compact, manually fed machines for mobile use on construction sites to fully automated large-scale systems (such as blow-in panels) for industrial element production in timber construction.

Multi-material capability: The systems are not limited to cellulose. They are designed to process a wide range of certified, blow-in insulation materials, including:

Cellulose
Wood fibre/wood wool
Rock wool
Glass wool
other ecological natural fibres

Intelligent material changeover in time with production: thanks to an intelligently coordinated system of hoses and the use of multiple supply units, different blow-in insulation materials can be flexibly processed within a single wall, ceiling or roof element. The insulation materials can thus be introduced into the individual compartments with absolute precision. In the fully automated section, the system controls the material changeover completely independently: through the assignment of defined material indices, the machine knows exactly which compartment requires which insulation material. The result is a highly efficient, precise and reliable combination of materials without time-consuming set-up times.

Why this versatility is crucial

By choosing the right level of automation, joinery firms and prefabricated house manufacturers can tailor their investments precisely to their order volume. The ability of the machinery to switch flexibly between different materials – for example, rock wool for enhanced fire safety requirements in commercial construction or cellulose and wood fibre for eco-friendly timber house construction – ensures the business is future-proof. Timber construction firms remain completely independent and can respond flexibly to specific customer requirements, tenders or legal requirements.

The green advantage: sustainability with ISOCELL cellulose

For those who wish to optimise not only maximum machine efficiency but also the building’s environmental footprint, cellulose insulation is the ideal solution: ISOCELL cellulose insulation (made from single-source newsprint) works perfectly in harmony with the building services systems. Thanks to its plant-based origin, it stores CO₂ over the long term and, in combination with precision machinery and our airtightness products, delivers an unbeatable all-round package for climate-positive and healthy timber construction.
