Add radiant barrier to attic.
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.
How radiant barriers help improve your energy efficiency.
With new types of technology and approaches to keep homes comfortable it s natural to wonder if attic radiant barrier works.
Radiant barriers are utilized to reduce summer heat gain in attics.
For the majority of installations there are basically two different methods used to install radiant barrier foil in an attic.
In the summer the sun heats up your roof and attic which makes the rest of the home warmer.
Radiant barrier should always be installed to work with the soffit and ridge.
Adding a radiant barrier to your attic will reflect heat and help your air conditioning system run more efficiently.
The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor.
It isn t the time tested fiberglass rolls of pink insulation.
Increasing summer energy consumption and cooling costs.
A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic.
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.
Finally if you re trying to reduce heat loss from the home into the attic you need to consider adding a radiant barrier over your insulation on the attic floor to help the home from radiating heat into the attic space.
A radiant barrier works best when it is perpendicular to the radiant energy striking it.
This method also reduces the heat subject to attic mounted ac duct work thereby allowing them to work more efficiently.
Attic area of 55 x 35 1925 sq ft x 1 3 for a medium pitch roof about 8 9ft high at peak 2 503 sq ft.
The purpose of a radiant barrier is to reflect heat.
For really high roofs you should consider doing a flat top installation for radiant barrier for tall 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.
The first is stapling foil to the bottom of the roof rafters the second is laying it out over the existing attic ceiling insulation.
Our superperf radiant barrier is an excellent choice especially in cold climates where moisture is a significant concern.
The latest tests and studies have shown that on average heat radiant barriers help reduce about 20 to 30 of energy lost provided that they re installed properly.
The temperature of the attic space increases and that heat is transferred to the building below.
