FORMA LOC
Hidden Fastener Standing Seam PanelOur Forma Loc panel system is a hidden fastener standing seam panel that offers easy installation for roofers and DIY homeowners alike. The panels snap onto each other to hide fasteners beneath, creating a clean and professional appearance to every installation. FormaLoc is available in 12" and 16" coverages with minor ribs or striations to minimize oil canning. Forma Loc works well for both roof (26ga only) or side panel applications. With long clean lines, this panel system provides recognized standing seam performance, while remaining an affordable product for a wide array of projects. Forma Loc should always be installed on solid decking.
Panel Specification & Installation Info:
- Note: Striations are recommended over minor ribs on all Forma Loc panels as they are much more effective in minimizing oil-canning.
- Note: Forma Loc panels installed on roofs must be 26 gauge.

Installation:
The use of a proper underlayment is vital to the performance of any roofing system. Forma Steel strongly recommends the use of a peel and stick membrane for any slopes lower than 3/12. Since every project is different, care and attention should be paid to the product that is being specified so that the building performs as designed.
Venting, breathability and water resistance are all components of a building envelope and should be confirmed with building designers for optimal performance.
