As a prefabricated construction material, GFRG products arrive at your construction site ready for installation and finishing. As designed, the products themselves meet all standard building requirements and additional options are often available in accordance with more stringent standards.
In order to continue meeting building codes in the completed construction or renovation project, the installer should follow the standardized instructions for GFRG installation.
Installer Standards for GFRG Products
GFRG has a relatively straightforward and easy installation process since even larger GFRG architectural elements are lightweight when completed, requiring minimal manpower and support to get them in place and secure them there. By meeting installation specifications, you can be sure that this part of the process adheres to all guidelines, results in a high quality build, and promotes an attractive appearance for the property.
During installation, the installer is responsible for these steps which will help guarantee the right results:
- Preparing Substrates and Surrounding Surfaces – The installer needs to prepare the existing structure for the installation of GFRG elements. This includes that any metal framing is already in place and will be sufficient to meet the weight requirements of the GFRG pieces. All structural elements should be completed in accordance with architectural drawings. They should also be straight and true within ⅛” per 8 feet to enable a flush and secure fit for any GFRG.
- Cleaning All Substrates – Surfaces should be clean before GFRG installation to avoid trapping dirt or any damage to GFRG products from corrosive debris.
- Install Shims and Brackets – The installer must provide the shims and brackets necessary for installation. All of these should be in place before installing the individual GFRG elements to ensure that the attachment will be secure.
- Attaching GFRG Elements – The installer should place each GFRG element as outlined by the drawings and with the fasteners recommended by the manufacturers. Further stabilization can use shims and countersunk screws to achieve a secure hold.
- Requirements for Suspended Elements – Adhere to the shop drawings for suspension point attachments. These are the minimum requirements in order to safely hold a GFRG element, but the installer should incorporate additional suspension points if necessary.
- Install Control Joints – If necessary based on the size of your product, the manufacturer will outline locations for control joints. Installing these allows the surface of elements to expand without cracking.
- Finish GFRG Surfaces – Joint treatments can create a final smooth surface. For textured GFRG, this surface is immediately ready for texturing treatment and painting. For smooth surfaces, the installer should sand prior to painting to remove any small bumps that are inherent with GFRG.
During this installation process, the installer must comply with ASTM C1467, which outlines the correct installation for glass fiber reinforced gypsum products.
