Grossbond FR
Aluminium composite panels Grossbond FR used for cladding facades of buildings for various purposes, as well as for interior decoration, where fire safety standards require low-combustible material.Aluminum composite panels are often used to clad ventilated facades. Over 50% of ventilated facades around the world are lined with aluminum composite panels. Grossbond FR aluminum composite panels have a multilayer structure. Layers have varying chemical structures and physical properties. The top and bottom layers are made of 0.1-0.5-mm-thick aluminum while the core comprises non-toxic polyethylene foam and aluminum hydroxide mixed with resin. These substances retard the burning rate and prevent combustion. Aluminum sheets are coated on both sides with several special layers — an anti-corrosion layer on the inner side and a protective layer of polyester or PVDF on the outer side.

Panel coatings
PVDF is a coating consisting of polyvinylidene fluoride (70%) and acrylic (30%). This material is resistant to ultraviolet rays and it does not practically fade. It has a smooth glossy surface. PVDF is resistant to mechanical impact. As the most durable coating, it has widely applications in aggressive environments.
Polyester is a coating that can be used in a variety of climatic conditions. It has a glossy surface. The prime coat is polyester paint having good color stability.
Nowadays building exterior finishing with Grossbond FR composite panels is an innovative and popular application. ACP’s can be both curved and smooth-surfaced with a wide range of colors. It sets the scene for original and advantageous architectural design solutions. The use of ventilated facades offers a host of advantages, since in addition to relative simplicity this finishing option provides additional performance. Buildings lined with aluminum composite panels keep the warmth indoors and are also highly moisture-and-soundproof.
Aluminum composite panels can be used in airports and health facilities because they shield electromagnetic waves. They are used to clad gas stations, various road infrastructure facilities and tunnels.
Grossbond FR ACP’s are certified to construction materials fire hazard class KM1 and are classified into group G1 (fire-retardant). These panels are manufactured for buildings of all fire resistance ratings and all structural and
functional fire hazard classes. A curtain wall ventilated facade system lined with Grossbond FR aluminum composite material is rated to fire hazard class K0. The calorific value of the material is 10.08 -10.63 MJ/kg.
