Company name
Armacell Benelux S.C.S
Description company activity

Armacell is a pioneer in the field of polyethylene terephthalate (PET) technology and initiated the breakthrough of PET foams as a structural core material in the composite industry (2005). But our research did not stop there; as a technology leader, Armacell went on to further developed its unique and patented rPET process technology that enables PET foam products to be made entirely from recycled beverage bottles (2010). Today, Armacell offers a diverse product portfolio of environmentally friendly solutions based on 100% recycled PET: structural foam cores, thermoformable flexible sheets and particle foams.

Our portfolio of eco-friendly product solutions with lowest ecological footprints contains structural and insulating foam cores, thin flexible sheets for thermoformable micro sandwich solutions and particle foams to produce 3D foam parts. All ArmaPET™ products are made by Armacell’s unique and patented rPET technology, enabling the production of PET foam products based on 100% recycled PET. ArmaPET™ is used in a variety of applications, such as 90-metre-long wind turbine blades, the body structure of high-speed trains, surfboards, or even the 24-karat gilded roof of an Orthodox cathedral in Paris. As of today, we have used more than 1,5 bn recycled bottles in our ArmaPET™ production.

A 186 m² house in Nova Scotia (Canada) made entirely of 170 ArmaPET Struct cored panels.
-Advantages: ArmaPET Eco combines insulation and structural integrity, ensuring energy and emission efficiency for decades of use.: This innovative and eco-friendly new concept home complies with all building codes. In fact, it out-performs traditional construction in a number of categories: it is strong enough to withstand Category 5 hurricane winds, it has minimal maintenance requirements and its energy efficiency ratings put it in the upper levels of the energy guide. The building costs for their prototype home were similar to those for a conventional construction of the same size but homeowners benefit from added value due to savings in whole-life costs. Moreover, the house assembly time is less than a day (14 h), so it is a perfect solution for sheltering.
-Materials: This prototype house is made of around 170 panels, all made of low density ArmaPET Struct with 4.4 lb/ft³ (70 kg/m³) and thicknesses of 1 to 6 inches (25 to 150 mm). Using the hand lay-up process ArmaPET Struct is covered with fiberglass/polyester resin skins. Aluminum siding is then applied on the outside and drywall on the inside.
-System and process: structural panels, hand lay-up process
-Development status: finished
-Development partners: Armacell x JD Composites

ArmaPET Struct is used for the five gilded domes of the Russian Orthodox Cathedral in Paris, France.
-Advantages: In contrast to conventional construction techniques, the choice of a composite dome solution had two major aspects. Cored with ArmaPET Struct, the weight of the bigger dome was reduced by a factor five, from 42 tones to 8 tones. The domes’ reduced weight allowed for less supporting structures and facilitated, as well as, speeded up handling during assembly. It took only 15 minutes (!) to put the bigger dome of 12 x 12 meters by crane in place. Moreover, the composite allows complicated designs and combination of concave to convex shapes.
-Materials: 50 mm thick composite sandwich structure cored with ArmaPET ™ Struct, at a density of 80 kg/m³ with grid-score finishing and reinforced with glass fiber/epoxy resin skins by a vacuum infusion process.
-System and process: vacuum infusion process
-Development status: finished
-Development partners: Armacell x Architect: Wilmotte & Associés x General contractor: Bouygues Bâtiment Ile-de-France x Contractor domes: Multiplast

ArmaPET Struct is used for the more than 3,000 façade panels of KAFD World Trade Center in Riyadh, Saudi Arabia, providing a required stiffness while keeping them lightweight. The up to 15 metres long panels are tailor-
made to meet stringent high-speed wind loading criteria.
-Advantages: ArmaPET boosts sustainable building, providing a higher degree of freedom in design, while contributing to improved safety and comfort: 3,180 unique facade panels spanning an area of 47,000 square meters. The large variations in the geometry of the panels. Off-site manufacturing required tight dimensional tolerances to ensure smooth assembly on-site. Exposure to high-speed wind loads required high structural strength at low weight. External fire testing of the entire facade panels proved that ArmaPET Struct complies in all relevant aspects of ASTM E84 (class A) and NFPA 285. Stiffness and, at the same time, lightweight and dimensional tolerances were not the only challenges the designers and architects had to cope with: the Arabian climate, with its extremely large variations in temperature, from sub-zero at night to +55°C during the summer, in combination with wind and sand, required the use of very robust materials. ArmaPET Struct provided enough temperature stability to manage these temperature changes.
-Materials: Composite sandwich panels made of fiberglass/fire-retardant gelcoat polyester skins and cored with low-density ArmaPET Struct of 70 kg/m³.
-System and process: vacuum infusion process
