New construction CA – builder used batting insulation @ roof deck
Hi folks. Lennar our builder used fiberglass batting under the roof deck instead of the standard radiant barrier roof. I found the Title 24 plans on my city website and this was approved in February 2020 so I don’t believe it was due to covid + supply chain issues….maybe just to cut costs? The whole development of 29 homes was designed this way.
My question is, is this a benefit or negative in the grand scheme of things? Our area (Nor Cal) seems to always uses the radiant barrier roof sheathing boards so this is new for us here.
Edit: sorry I should have said there will be blown in insulation on the attic floor and instead of radiant barrier roof sheathing they stapled fiberglass batting under the roof deck inside the attic.
