Eagle Shield Radiant Barrier

Walls

Radiant barrier may be used as a vented skin around the exterior of a wall. Furring strips are applied to the sheathing to create a vented air space between the radiant barrier and the siding, and vents are used at the top and bottom to allow convective heat to rise naturally to the attic. If brick is being used on the exterior, then a vented air space may already be present, and furring strips are not necessary. Wrapping a house with radiant barrier can result in a 10% to 20% reduction in the tonnage air conditioning system requirement, and save both energy and construction costs.

Eagle Shield Reflective Insulation - Building insulation Advantages

- Blocks airflow by expanding and sealing off leaks, gaps and penetrations.
- Can serve as a semi-permeable vapor barrier with a better permeability rating than plastic sheeting vapor barriers and consequently reduce the build up of moisture, which can cause mold growth.
- Can fill wall cavities in finished walls without tearing the walls apart (as required with batts).
- Works well in tight spaces (like loose-fill, but superior).
- Provides acoustical insulation (like loose-fill, but superior).
- Expands while curing, filling bypasses, and providing excellent resistance to air infiltration (unlike batts and blankets, which can leave bypasses and air pockets, and superior to some types of loose-fill. Wet-spray cellulose is comparable.).
- Increases structural stability (unlike loose-fill, similar to wet-spray cellulose).
- Can be used in places where loose-fill cannot, such as between joists and rafters. When used between rafters, the spray foam can cover up the nails protruding from the underside of the sheathing, protecting your head.
- Can be applied in small quantities.
- Cementitious foam is fireproof.

Floors

Radiant barriers are also quite effective in floor systems above unheated basements and crawl spaces. The radiant barrier may be either stapled below the floor joists, creating a single reflective air space, or between the joists, followed by some type of sheathing. Radiant barrier works extremely well in this application for two reasons.[9] First, a radiant barrier that is not perforated for breathability acts as an excellent vapor barrier. This means that ground moisture will not be able to pass through the radiant barrier and enter the living space. Secondly, the floor is the only part of the building where the heat flow is always down, unlike a roof where the heat would be coming down during the summer and rising to escape in the winter.[13] When the heat flow is down, 93% of the heat is radiant heat, which is exactly what the radiant barrier is designed to block.

Eagle Shield Industries - Thermal bridge

Thermal bridges are points in the building envelope that allow heat conduction to occur. Since heat flows through the path of least resistance, thermal bridges can contribute to poor energy performance. A thermal bridge is created when materials create a continuous path across a temperature difference, in which the heat flow is not interrupted by thermal insulation. Common building materials that are poor insulators include glass and metal.

Eagle Shield Radiant Barrier terms and definitions:

Insulation Density

Denser insulation products generally have more fibers in the same given area and generally have greater insulating power.

Knee Walls

Walls of varying length. Used to provide additional support to roof rafters with a wide span or to finish off an attic. An example of these are the short walls usually found in the top floor/attic of a cape cod style home.

Eagle Shield Franchise Group

Lath High Rib

A metal lath with a built-in rib used to provide air space under insulation applications.

Impact Resistance

Capability of an insulation material and/or finish to withstand mechanical or physical abuse.
