The osb techshield radiant barrier osb is engineered to improve energy efficiency.
Roof radian barrier specs.
The problem with putting any r value on a roof is that the roof is normally not really part of the thermal envelope.
Find out whether it s worth the money to install a radiant barrier in your attic.
The roof just keeps it dry.
The thermal envelope is usually your walls and ceiling.
The answer is that there are other things you can do that would be more effective in terms of energy efficiency.
Perforated house wrap radiant barrier foil 48 wide.
Above sheathing ventilation with radiant barrier roof assemblies sharkskin ventilated roof mat w sharkskin ultra radiant create both above sheathing ventilation asv and sharkskin ultra radiant reflects radiant heat and creates a cooler attic which reduces 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.
The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor.
So you want r value on your attic floor and radiant barrier at the roof.
Installing 19 inches of batt insulation or 22 of blown in is the single most cost effective way to reduce your heating and cooling costs.
Other kinds of radiant barriers combine reflective materials usually aluminium foil with materials like plastic films cardboard and kraft paper.
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.
Your radiant barrier makes the roof deck sheathing invisible from the attic.

How to measure your attic.
For example most homes don t have enough insulation to start with.
This reflection insulation also has high mechanical properties making it perfect for load bearing applications in construction.
Since radiant heat is in a waveform it can be reflected.

Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits.
A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.
A radiant barrier works best when it is perpendicular to the radiant energy striking it.
Installed in over 1 5 million homes in the united states lp techshield panels also lower attic temperatures up to 30 f.
This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.
