What is radiant barrier plywood?

Radiant barrier sheathing panels are engineered wood panels with a thin layer of highly-reflective aluminum facing that reduces radiant heat gain into the attic. The result is a cooler attic, which can equate to lower utility bills, improved energy efficiency and a more comfortable indoor environment.

What is solar board used for?

Solarbord is a radiant barrier sheathing product for roofs and exterior walls that consists of heat-reflecting foil laminated to OSB. Reduces radiant heat transfer through the roof by up to 97%. Reduces attic temperatures by up to 30ºF. Increases the efficiency of attic duct work.

What is radiant barrier plywood used for?

This radiant barrier plywood is generally used for new roofing applications with the reflective siding facing into the attic space. Felt and shingles are then applied over the top of the roof decking as usual.

Is radiant barrier sheathing worth it?

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.

Can radiant barrier cause mold?

When radiant barriers develop moisture problems, they can impact the efficiency of heat repellency. In addition, unchecked moisture can drop down onto other surfaces in the attic, causing water damage and mold. In order to prevent moisture issues, it’s imperative to use perforated radiant barriers.

How much does a solar panel cost?

for 14% efficiency, the cost ranges from Rs 52 per Wp for 200-250 W to Rs 88 per Wp for 0-50W. in case of panels with 15% efficiency, the cost ranges from Rs 37 per Wp for 250-300 W to Rs 63 per Wp for 50-100 W. for 16% efficiency, the cost ranges from Rs 37 per Wp for above 300 W to Rs 68 per Wp for 50-100 W.

What is OSB backing?

Oriented strand board (OSB), with a thin layer of low emitting aluminum foil attached to one side, is a common type of thermal-radiant-barrier sheathing. Foil-backed OSB is applied mostly in attics; however, it is also used in wall systems.

What is thermostat plywood?

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. This improved energy efficiency makes Thermostat radiant barrier the ideal choice for new homes, additions and renovations in warm to hot climates.

Can I install radiant barrier under shingles?

You can install the radiant barrier foil below the raised shingles either on top or below the battens. The easiest and best way is to run the foil out over the roofing felt, tack it down and then install the battens followed by shingles or metal roofing.

Will radiant barrier damage shingles?

By blocking the mass insulation from absorbing heat and emitting it back to the roof, a radiant barrier can decrease the roof temperature at night by over 5 degrees. In short, radiant barrier should not void any shingle manufacturer’s warranty and will not damage roof shingles or any other roofing material.

Which way should radiant barrier face?

Basically plywood or OSB sheathing with a thin aluminum facing on one side, radiant-barrier sheathing installs like any other roof sheathing. You just have to keep the shiny side face down. You might wonder why the shiny side facing down wouldn’t just reflect heat back into the attic.
