MEG Rainscreen Panels use a “double-wall construction”. The inner structural wall of the building is covered with a water-resistant barrier. The profiles are then attached to the structural wall and the exterior cladding is fixed to the profiles. The open joints between the exterior panels allow any rain that does penetrate to drain, evaporate or dry via “chimney effect”. A rainscreen system can improve the performance of the building’s interior climate by allowing moisture to escape and preventing mold formation. Rainscreen cladding also allows heat from the sun to be dispersed, which can prevent temperature fluctuations on the building’s interior and improve the overall energy efficiency of the building.
MEG Panel Maintenance
The hard, durable surface of MEG panels requires little maintenance. MEG panels can be cleaned with a mild, non-abrasive detergent dissolved in water using a sponge and/or a soft cloth. After cleaning, rinse thoroughly with water. We recommend whipping the panels dry after cleaning to avoid leaving water marks. Avoid excessive rubbing, pressure or using abrasive aids that could cause abrasion marks or scratches. A high-pressure cleaner may be used provided that the pressure does not exceed 1500 PSI. Using a dirt scraper is not advisable.
MEG panels do not require anti-graffiti treatment. MEG’s chemical resistant nature and closed structure do not allow most types of paints, inks, or lipstick to adhere to the surface or penetrate to the core. If the MEG surface becomes coated with graffiti, it can be removed using specific products designed to remove paint from plastic materials, which do not harm the original appearance of the surface. These products are commercially available. Most of these can also be used to remove stubborn dirt such as grease, mold, mildew, etc. Follow the product supplier’s instructions and after treatment, rinse the surface thoroughly with water. We suggest GR1 by 3M. When cleaning MEG panels, it is always suggested that a small, hidden area be tested first to assure the solution is appropriate for the MEG panels.
MEG panels are composed of 60-70% cellulose fiber and 30-40% thermosetting resins, free from asbestos and heavy metals. MEG panels do not release any gases, vapors, solvents or fluids into the environment and are not harmful to one’s health. MEG has a positive life cycle assessment (LCA) based on standard ISO 14040 series, which aims to determine a product’s impact on the environment by taking into account the materials and energy used, and emissions released, in all stages of the product’s life including manufacturing, fabrication, and disposal of scrapped product.
The high-pressure laminate that comprises MEG panels is GREENGUARD Certified, meaning that it doesn’t “off-gas” if used indoors. MEG’s exterior-grade phenolic panels consist of a core of Kraft paper and an exterior layer of decorative paper that are impregnated with thermosetting phenolic and melamine resins bonded together with heat and high pressure.
