A radiant barrier works best when it is perpendicular to the radiant energy striking it.

A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.
Spray the adhesive to the masking paper in a 2ft wide pattern.
This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.
Installing radiant barrier under the roof decking is the preferred method versus on top of the insulation because it gives an air gap for the heat to escape to the ridge vent without creating a potential moisture problem between the radiant barrier and the attic floor.
Also the greater the temperature difference between the sides of the radiant barrier material the greater the benefits a radiant barrier can offer.
Increasing summer energy consumption and cooling costs.
This method can be used in any climate though it historically has been most popular in colder climates.
Atticfoil is the proven solution for 250 000 homes.
I then used a broom to clean and press the foil to the paper.
In an open framed attic it is generally easiest to install the strips of radiant barrier roof material across the attic perpendicular to the direction of the roof joists overlapping each run by about 2 inches.
Staples should be placed 14 to 18 inches apart.
When you reach the desired length cut the now finished radiant barrier leave the excess 1 ft until installation.
But radiant barrier maybe but it s kind of hard to tell because there s a lot of claims of energy efficiency but it s very difficult to prove it out.
Continue covering the attic floor by overlapping each section of radiant barrier already rolled out by 2 inches.
Radiant barrier should always be installed to work with the soffit and ridge.
Then roll the aluminum foil out starting with the left roll and over lap 1 16th with the second roll.
Starting at one end of your attic install our ultima foil breathable radiant barrier over across attic floor joists.
When laying the foil insulation it is not.
The temperature of the attic space increases and that heat is transferred to the building below.
This is an awesome product.
But on the bright side.
This is probably the easiest method to install radiant barrier atticfoil is to lay the foil out over the existing insulation on the attic floor.
Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits.
Our do it yourself radiant barrier will make your home more comfortable and energy efficient.
Radiant barriers are utilized to reduce summer heat gain in attics.
Attics heat up when the sun s radiant energy heats the shingles and the heat is transferred to the interior attic space through the roofing materials via conduction.
If your house doesn t have continuous ridge and soffit vents so it s trapping excess heat in the attic that s a very cost effective improvement.
Unroll the radiant barrier hold in place and staple to bottom of roof joists.
