Metallic vs. Non-Metallic Insulation Cladding

It is standard practice to use cladding over insulation to prevent water intrusion, the cause of CUI (Corrosion Under Insulation). The materials used for cladding can be non-metallic or sheet metal (metallic) cladding. The key to an effective insulation cladding system is the use of appropriate cladding material. Below is a quick brief of metallic and non-metallic cladding and the advantages of each solution.

What is Non-Metallic Insulation Cladding?

Non-Metallic insulation cladding has been widely used back in 1997 until now. This type of insulation cladding uses pre-formed or uncured sheeted quality grade isophthalic polyester resins and cut glass fibers. Special adhesives are applied to the pre-formed non-metallic cladding material to ensure the durability of the cladding system, where uncured GRP has its own adhesion. There are no screws or rivets needed to hold the entire cladding materials in place.

What is Metallic Insulation Cladding?

Metallic cladding makes use of sheet metal, aluminum or stainless steel. They have been proven to be effective barriers against weather conditions including chemicals. Metallic insulation cladding system requires the use of rivets and screws to hold the metal together. As this happens the issue of penetration of external elements is a big problem because the barrier is affected due to the tapping of screws or rivets. Top performing sealant is needed to preserve the durability of the metallic cladding insulation system. Metallic insulation cladding is not recommended for the pre-cladded system or with modular designs because the metal sheet used have the tendency to dent. Aside from that, maintenance of metallic insulation cladding system may require huge budget as compared to non-metallic.

Why is Non-Metallic widely favored?

• Flexible

Since the material used for non-metallic cladding is from a pliable top graded plastic material, the installation process is a lot easier as compared to sheet metal. They can be easily modified and cut for accurate fitting, especially uncured GRP systems as SolarTech GRP.

• Chemical resistant

The components found on non-metallic material have superb resistance feature on chemicals than the metallic cladding.

• Suitable for fire-rated areas

Non-metallic insulation cladding is suitable for fire-rated areas because they have self-extinguishing feature and passed the fire standards.

• Ideal for industrial and offshore industries

The non-metallic insulation cladding can be seen mostly in industries like huge plants (power plants, food processing plants, mineral processing plants). They are also used in refineries including chemical facilities.

To learn more about nonmetallic cladding such as the use of GRP or glass reinforced plastic. Corrotech Construction Chemicals can give you further explanation of Solartech GRP, a popular brand used globally as an alternative to traditional metal insulation cladding.
