HIRSCH Insulation renews its Foundations range and strengthens its industrial capacity

A range designed for the different constraints of construction sites

Insulating buried sections requires addressing specific constraints related to mechanical resistance, humidity, and burial depth. To meet all these needs, HIRSCH Insulation has restructured its product range around several solutions suitable for both individual homes and more complex structures, such as underground parking garages.

The main new feature is the Cellomur® Ultra Foundation, a graphite-enhanced expanded polystyrene panel designed for the first buried courses. Thanks to its high thermal performance, it allows for reduced insulation thicknesses while ensuring continuity with external thermal insulation on the facade, a particularly sought-after feature in projects subject to the RE2020 requirements.

Solutions up to nearly 10 meters deep

The new range now extends from common applications to the most demanding configurations.

The signs Cellomur® Foundation, Fondaplus et Fondamax They are designed to withstand increasing burial depths of up to 9,50 meters, depending on site conditions. This capability is particularly suited to deep underground structures and underground parking facilities, where compressive stresses are especially significant.

The permissible depth depends however on several parameters, including the nature of the soil, the presence of traffic or parking areas and the mechanical resistance of the chosen insulation, in accordance with the CSFE professional recommendations relating to the insulation of buried walls.

Insulation, drainage and protection combined in a single system

Beyond just thermal function, HIRSCH Insulation develops multifunctional panels designed to simplify implementation on site.

Le Cellodrain® Ultra This system combines insulation, drainage, and protection of the waterproofing membrane thanks to a studded surface combined with a geotextile. Other examples include Cellocem® Ultralight et Cellocem® Ultra, incorporate a wood-cement or fiber-cement facing to protect the exposed foundations while providing a directly usable finish.

An approach geared towards a circular economy

All expanded polystyrene products in this range are advertised as 100% recyclable and incorporates a portion of recycled material.

This development is part of HIRSCH Insulation's ongoing recycling strategy, which already utilizes production offcuts and certain construction waste in its industrial processes. The future integration of the product range into the manufacturer's Environmental Product Declaration (EPD) configurator should also facilitate the environmental assessment of projects.

A robotic production line to support business growth

To support this product range overhaul, HIRSCH Insulation has invested several hundred thousand euros in a new automated assembly line in Guipry-Messac.

The equipment is used, in particular, for bonding the panels and their finishing facings. According to the manufacturer, this automation doubles production capacity while improving working conditions for operators. The stated objective is to guarantee delivery times of between three and five days across the entire country.

With this new Foundations range, HIRSCH Insulation aims to meet the demands of a market driven by increasingly stringent thermal requirements and a growing emphasis on the performance of the building's underground sections. Between insulation, moisture management, and mechanical constraints, these areas, long considered secondary, are now becoming integral components of the building envelope's overall performance.
