Is TechShield a vapor barrier?

Is TechShield a vapor barrier?

Only LP TechShield sheathing features a durable layer of aluminum with patented VaporVents™ technology. Post-lamination incising prevents moisture build-up during and after construction, while the OSB substrate promotes breathability and does not create a vapor barrier.

Is radiant barrier OSB worth it?

If you use OSB radiant barrier sheathing, you can reflect up to ninety-seven percent of solar radiation. This amount of solar heat reduction can reduce your attic’s heat by up to thirty degrees Fahrenheit. Radiant barrier roof sheathing can also improve comfort in other areas.

Does TechShield really work?

For most new construction projects, I recommend using TechShield® (or another brand). The products work well, the cost of upgrading from regular OSB decking to radiant barrier decking is pretty minimal and there is NO additional labor cost since the Techshield® is installed just like a regular OSB roof deck.

Can you paint over TechShield?

#4: If you’re planning on an open or exposed ceiling design—for example in a loft space or garage or shed—do not paint the LP TechShield Radiant Barrier sheathing. The aluminum foil-like overlay allows the radiant barrier to work while the VaporVents™ technology allows the panel to breathe and lets moisture escape.

What is radiant OSB?

A radiant barrier that turns down the temperature and helps turn up the savings. Thermostat® radiant barrier sheathing reflects up to 97% of the sun’s radiant heat from a home’s attic and can help lower attic temperatures by up to 30°F.

Is radiant barrier worth the money?

Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. In cool climates, however, it’s usually more cost-effective to install more thermal insulation than to add a radiant barrier.
