Roof Deck Radiant Barrier

Installing a radiant barrier underneath the roof will cause the roof temperature to increase by a few degrees usually 2 10º.

Roof deck radiant barrier.

April 19 2019 posted in. There is a way to incorporate radiant barrier foil into a re roofing application. Your radiant barrier makes the roof deck sheathing invisible from the attic. The reflective material which is usually aluminum is applied to either one or both sides of the material that is being used as a barrier.

Radiant barriers come in a variety of forms. As a result your home s interior temperature will stabilize creating improved comfort for you and your family. There are several types of roofs that have an air space between the roofing material and the roof deck. The only way is if you can create an air space on one side of the foil.

Increasing summer energy consumption and cooling costs. 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. Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f. It reduces attic temperatures by up to 30 degrees fahrenheit and it blocks up to 97 of radiant heat.

Radiant barriers are utilized to reduce summer heat gain in attics. 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. Since these barriers don t provide additional thermal insulation they can be combined with insulation to achieve the desired result. Product overview the osb techshield radiant barrier osb is engineered to improve energy efficiency.

A radiant barrier can be effective with an asphalt shingle roof only when installed inside the attic either to the underside of the roof decking or to the underside of the roof rafters. But on the bright side. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. This can be roof shingles reflective chips roof sheathing etc.

In these attic space applications there is an air space below the radiant barrier. This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction. The temperature of the attic space increases and that heat is transferred to the building below. This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.

The heat that would normally be absorbed by the insulation is now being bounced back to the roof deck and causing the roof to emit more heat upward rather than both upward and downward.
