There are plenty of things you ought to take note of when deciding on the appropriate insulating material. It should abide by existing energy codes, to begin with. It should likewise meet the criteria of your property insurance provider and, of course, be well-suited to your home's roof design.
A sensible choice of insulating material produces an efficient and long-lasting roofing system. A subpar choice brings about unsatisfactory roof performance, which gets readily noticeable a short time after installation. Thankfully, Federal Way and Des Moines roofing contractors can help you make the first one.
It is essential to find out which roof insulation material goes (or does not go) with particular types of roofing systems. For instance, polystyrene should not be placed in direct contact with thermoplastic PVC single-ply membranes. Doing this triggers plasticizer migration, which makes the PVC membrane brittle. Similarly, typical built-up, in addition to modified bitumen membranes, ought to not be directly administered over foam plastic insulation boards. Cover board insulation is instead recommended for these roofing materials.
One more consideration is whether a specific insulation material is approved for a certain roof deck type. Building regulations allow, for instance, the direct application of polystyrene and polyisocyanurate over steel roof decks—as long as the manufacturer of the material has tried out and passed the necessary tests. Certain remedial procedures, though, may be taken if the roof insulation product has not passed the required tests. In the example above, a thermal barrier (such as gypsum or perlite), may be placed below the foam plastic insulation.
Insurance provider requirements should also be regarded when picking a roof insulation material. A lot of properties in Washington and all over the United States are insured by an FM Global associate or a company that requires FM Global-approved roof assemblies. These types of approvals are extremely particular concerning the type, manufacturer, and configuration of the roof insulation material.
