Engebold FR

The Engebold FR ACM is a composite aluminum panel developed for applications that require greater control over flame spread. Its structure is made of two aluminum sheets and a fire-retardant mineral core, providing superior behavior in situations of thermal risk when compared to traditional polyethylene cores.

It is recommended for technical façades, corporate buildings and projects that demand a higher level of safety, while maintaining dimensional stability and good structural performance. The material withstands continuous thermal variations, operating safely at very high temperatures.

Engebold FR allows complete machining, cutting, bending and drilling processes, enabling its application in different construction systems. Its surface receives adequate treatment for resistance to weathering, UV radiation and corrosion, ensuring durability, visual integrity and ease of maintenance over time.

• The panels must be stored in a covered, dry place, protected from direct sunlight before installation.
• Avoid excessive stacking and improper handling that could compromise the integrity of the material.
• During transport, keep the panels fully supported, preventing impacts and deformations.
• Installation must take into account the technical requirements for fire-resistant materials, using compatible fastening systems and respecting the gaps for thermal expansion.
• The use of suitable fasteners and sealing materials compatible with outdoor applications is recommended.
• Periodic cleaning should be carried out with water and neutral detergent, using soft cloths.
• Avoid the use of abrasive products, aggressive solvents and high-pressure equipment.
