Radiant Barrier Insulation Roof Sheathing

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.

Radiant barrier insulation roof sheathing.

Which type of radiant barrier is best. This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern. Radiant barrier paint performed the worse providing a heat decrease in the conditioned space of around 19. A control study was published in 2013 showing the radiant barrier effectiveness of paint foil backed sheathing and foil that was stapled onto the rafters.

As the original 1 brand of radiant barrier sheathing lp techshield panels vaporvents technology prevents moisture buildup during and after construction while blocking up to 97 of radiant heat in roof panels. Types of radiant barriers radiant barriers consist of a highly reflective material usually aluminum foil which is applied to one or both sides of a number of substrate materials such as kraft paper plastic films cardboard oriented strand board and air infiltration barrier material. The results were very telling. Foil backed osb is applied mostly in attics.

The radiant barrier reflects 95 of the radiant heat back to the roofing materials which then emits over 90 of the heat out the roof almost instantly. Radiantguard radiant barrier foil insulation installed in an attics can reduce attic temperatures by up to 30 degrees when stapled with a staple gun to the underside of roof rafters by reflecting up to 97 of the radiant heat that strikes its surface thereby reducing heat transfer from the attic to living spaces resulting in lower utility bills. In cool climates however it s usually more cost effective to install more thermal insulation than to add a radiant barrier. With no barrier to restrict the heat it radiates through the insulation into living spaces causing room temperatures to rise.

The most effective radiant barrier sheathing is a structural roof sheathing panel which consists of an osb panel with heat reflecting foil laminated to one side. Radiant energy transferred through standard roof sheathing creates heat build up in the attic. However it is also used in wall systems. More energy is needed to cool the house and that means higher energy costs for homeowners.

But on the bright side. Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. Other kinds of radiant barriers combine reflective materials usually aluminium foil with materials like plastic films cardboard and kraft paper.
