MULTI LAYER RADIANT BARRIERS & INSULATION

Summer Conditions

Silver Shield ML
Radiant Barrier

* 20 YEAR TRANSFERRABLE LIMITED WARRANTY
* TWO LAYERS of protection with air spaces to enhance performance
* MINIMUM 17 % IMPROVEMENT in performance over standard deck applied radiant barrier applications

Most Effective -Best Installation Method

Deck Applied
Radiant Barrier

* Only one layer of protection
* No additional air spaces

* Pure conduction of heat occurs where Radiant Barrier is sandwiched between trust and roof deck

* Trusses reradiate heat down, reducing overall performance

Not as Effective

FACT: Trust / Rafter mounted Radiant Barriers provides BETTER OVERALL PERFORMANCE by reducing conduction thru the trust / rafters and roof decking .

FACT: Silver Shield is a Multi-layer radiant barrier. The layers expand to form a reflective air space. Of the various methods of installing a radiant barrier, installation to the bottom of the top cord of the roof trust / rafters will yield the BEST PERFORMANCE.

* 20 YEAR TRANSFERRABLE LIMITED WARRANTY

Silver Shield Hi-Perm is a multi-layer radiant barrier. The inside layer is metalized PVC. The outer layer is
.000285" aluminum foil laminated with a fire retardant adhesive to 30 lb. natural kraft, and is reinforced
with a tri-directional fiberglass and polyester scrim. Silver Shield is intended for use on the underside
roof rafters, and can be used in ceiling and wall / floor applications where additional radiant heat
protection is desired. Excellent for installations between roof trust systems of 16" & 24" .

Silver Shield Radiant Barrier System

Stops 97 % of Radiant Heat.

An attic offers excellent potential for use of radiant barrier systems: First, because the roof is the surface most exposed to
solar radiation, and second, because most of the solar gain absorbed by the roof is transmitted down to the attic floor by
radiation. Since the attic airspace separates the hot roof surface from the ceiling, no heat will move down by conduction, and
the heat will not convect down from the hot roof to the ceiling because heated air rises. If you place a radiant barrier (layer of
foil) in the airspace between the hot roof deck and the cooler attic floor (insulation), you can eliminate almost all radiant heat
transfer.

THE PROBLEM

Solar radiation causes roof temperatures to reach 160 o to 190 o F.
Heat is conducted through roofing materials and radiated to the ceiling below.
Attic air temperatures climb to superheated levels...typically 140 o F in the summer.
Ceiling insulation R-values are rated at 75 degrees and 50% relative humidity, as temperatures and humidity levels increase, R-values diminish.
Radiant heat transfers into air conditioning ducts increasing energy costs.
Attic structure and contents saturate and continue to transfer heat even after the sun has set.
A/C run time increases and in peak loads cannot maintain internal temperature set points - comfort is compromised.
Air quality is compromised - hot humid air is drawn through leaks in the duct system.

THE SOLUTION

Silver Shield Radiant Barrier System

Reduces radiant heat transfer up to 97%. Treats the problem at its source ----- the roof.
Significantly reduces attic temperatures up to 30 degrees.
Increases insulation and air conditioning duct efficiency.
Lowers temperatures and improves comfort in areas that are not typically air conditioned, such as garages and lanais.
Qualifies for Florida Energy Code Credits.
Energy Star Rating helps to qualify for energy efficient mortgages.

Of the three methods, installing a radiant barrier to the bottom of the top cord is the most effective for
reducing radiant heat transfer. This installation method yields a 15% to 20% performance improvement.
In addition, the top cord installation method reduces material costs especially in hip roof configurations.

Radiant barriers are great for bonus rooms and other problem areas for cooling design.
Installing radiant barriers in garages, lanais, and gable ends improves overall performance and comfort in building design.
Radiant barriers will not harm roofing materials including shingles.

MULTI LAYER WALL INSULATION

VR Plus is a multi-layer reflective insulation that is not only for new construction applications, but
also allows for retrofit on current housing. This unique insulation has expanding layers that separate
paper from foil creating three reflective air spaces, which creates unsurpassed insulation with
R-Values of 5.2 to 7.1.

Background

Concrete masonry homes are less expensive to heat and cool than insulated wood frame homes. Much of this energy efficiency is attributed to the mass of a concrete wall. In Florida, a concrete wall takes advantage of differences in night and day temperature by responding to changes very slowly. As a result, less energy is required to maintain a comfortable constant temperature inside your home. It may take 4 to 8 hours for a temperature change to migrate through the mass of an insulated con-crete block wall and only about 1 hour for an insulated wood frame wall. For example, a wood frame construction in Tampa must have three times the R-Value than is required for a masonry home."

Masonry Walls have built-in insulation

Reduce heat gain and loss with mass
Small portion of overall load - 7% (see pie chart)
Masonry Wall with an R-4 added insulation is equivalent to an R-13 frame wall
Invested energy dollar is better spent on higher load areas in the structure such as roof systems, windows, infiltration, and mechanical systems

Solution

VR Plus Shield achieves an R-7.1 on 1-1/2" furring for higher requirements
Achieves R-value requirement at lowest cost
Also serves as an infiltration and vapor barrier
Safe for the Environment - no ozone or greenhouse gases
Stable R-value - no gases to leak out or mass to hold moisture
Meets Florida Energy Code
Energy Star Rating SBCCI & Dade County Compliance
Millions of square feet installed
