Tapered insulation resources
Whether you need designs, layout strategies, or just suggestions on how to handle unique job site conditions, the GAF Tapered Design Group offers trained specialists and a comprehensive offering of products and other resources.
Standard VS. Extended Panel Systems
Extended panel systems use larger-than-standard insulation boards as fill and base layers in order to increase installation efficiency. As shown in the diagram, this results in fewer layers, which in turn can help reduce the amount of panels and adhesive needed to install the tapered system.![Diagram of standard vs extended taper insulation panel systems](https://www.gaf.com/-/media/tapered-design/feature_standardvexpanded-systems.jpg?h=663&w=1272&la=en-US&hash=CAE784A436D3B95FD7099FC6E60E684518D40FBF)
