Radiant barrier OSB help needed
Wondering if it would be worth it to upgrade to a radiant barrier roof deck for the following scenario?
– Vented, unconditioned, attic.
– Hvac equipment located in attic (Furnace, erv, duct lines)
– Zone 4a North West Arkansas
1). Would the radiant barrier reduce attic temperatures enough to extend the life of the hvac equipment?
2). Would people prefer to have a 7/16 radiant barrier roof deck or a true 1/2″ OSB non radiant barrier roof deck – for the above scenario?
Essentially, wondering if $$$ is better spent on a thinner OSB radiant barrier roof deck or a thicker NON radiant barrier roof deck.
Thank you for the replies in advance.
