Summary for decision-makers

The car park at the Gustave Roussy Institute in Villejuif (94) is undergoing renovation, with the innovation of a modern insulation solution, FOAMGLAS® Enrobé. Selected by the E-LEVEN technical design office, this solution consists of two 5 cm layers of asphalt, providing both the wearing course and the protection of a high-performance insulating complex (FOAMGLAS® READY F) combined with effective waterproofing (Derbicoat Uni and Derbigum GC4).

One of the major characteristics of FOAMGLAS® is its compressive strength, certified at 1 kPa, which guarantees optimal durability over time. Used in this project, the "iso-waterproof" system saves the concrete slab, thus facilitating implementation and speed of operation, with a roof accessible to pedestrians the day after the asphalt pouring. This solution was chosen for its ability to reduce the risks associated with settlement and water infiltration, thus contributing to a sustainable and efficient renovation of the parking lot.

Frequently Asked Questions for Decision Makers

What technology is used to insulate the Gustave Roussy Institute parking lot?
The technology used is FOAMGLAS® Coated, which combines cellular glass insulation and coating for a durable solution.

What advantages does FOAMGLAS® offer over traditional solutions?
FOAMGLAS® offers high compressive strength, increased durability, and allows for rapid installation, making the roof usable immediately after work.

How does FOAMGLAS® contribute to parking safety?
FOAMGLAS® reduces the risk of settlement and water infiltration, ensuring a safer roof for users.

The high compressive strength without settling of FOAMGLAS® offers an innovative solution for roofs accessible to pedestrians, and for parking lots for light and heavy vehicles. A new specification approved by SOCOTEC enhances this solution (December 2021).

Solid and waterproof accessible roofs

The car park at the Gustave Roussy Institute in Villejuif (94) is currently undergoing renovation, and the FOAMGLAS® Enrobé solution was selected by the project management, the E-LEVEN technical design office. Two layers of asphalt, each 5 cm thick, form the wearing course and the protection of the insulating complex (FOAMGLAS® READY F) + waterproofing (Derbicoat Uni and Derbigum GC4).

The values of the compressive strengths of the insulators are validated at the factory, and manufacturers are not yet required to commit to a minimum value for these physical characteristics over 10 years in situ.

One of the secrets of FOAMGLAS® cellular glass

For this type of roof, the strength of FOAMGLAS® cellular glass insulation, made of waterproof and rigid bubbles, 100% glass, without resin or binder, comes from its compressive strength: it is high and, above all, it does not decrease over time, as demonstrated by analyses carried out on projects dating back more than 40 years.

FOAMGLAS® F, used for the Gustave Roussy Institute car park, has a compressive strength of 1 kPa (600 T/m160).

Using this physical property of cellular glass, Pittsburgh Corning France has developed an "iso-waterproof" system for accessible roofs protected directly and solely by asphalt. It saves on the traditional protective concrete slab above the waterproofing for car and truck parking areas. It reduces the thickness of complexes intended for roofs accessible to pedestrians. It also stands out for its highly appreciated speed of installation, with the roof becoming usable the day after the asphalt is poured.

It is this speed of implementation, in addition to the safety it provides against the risks of settlement and the risks of water infiltration (FOAMGLAS® compact roof) which was decisive in the choice of this solution for the car park of the Gustave Roussy Institute.
