Note: Embossed shade material is available. The embossing process has no measurable effect on the performance characteristics of the film.
Definition of technical terms:
Percentage of visible light transmittance (VLT) refers only to the amount of visible wavelengths of light that is transmitted, i.e. how much sunlight is allowed to enter. The lower the percentage, the less light and greater glare protection.
Percentage of ultra-violet transmittance is the amount of energy that is transmitted with a wavelength under 370 angstoms. Ultraviolet radiation is one of the contributing factors in the fading process of interior furnishings. (All Plastic View shade materials have special UV inhibitors that stop virtually 99% of all ultraviolet radiation from entering.)
Percentage of solar reflectance is the ratio of the total visible solar energy that is reflected by the shade material.
Percentage of solar energy transmittance is the ratio of the amount of total solar energy in the full solar wavelength range that passes directly through the shade material.
Winter U Value is expressed in terms of BTU/Sq. Ft. per HR/F and is the overall heat transfer coefficient of the material. It is a measure of the insulation capabilities of the glass and film in reducing heat flow in either direction. The U factor measures heat conduction from sources other than radiant. The lower the number the better the insulating capability.
Percentage of solar absorption is the ratio of the amount of total solar radiation energy that the material prevents from passing through, i.e. how much of the heat is being blocked or prevented from directly passing through the shade material.
Shading Coefficient is the ratio of solar heat gain of any glazing system compared to untreated clear glass. The lower the number, the more effective the material is in keeping radiant solar heat out. For example, Duplex Ice has a shading coefficient of only .29 which means that only 29% of the radiant heat is allowed to pass...a full 71% is reflected.
Percentage of total energy rejected is the amount of solar energy/heat that is reflected and absorbed and takes into consideration the NI Factor, which is how much of the absorbed energy is re-radiated inward.

How to determine the best selection of window shade materials and roller types
1. Decide which "problems / conditions must be resolved.
2. Select the most decorative colors / style / texture material that resolves these problems / conditions.
3. Determine the most functional roller type, consistant with ease of operation and bracket location.
Problems / Conditions
Decorative with Energy Efficiency MESH SHEERWEAVE has a very stylish textured look and feel. The classic designer patterns and carefully chosen colors give tremendous decorating freedom and versatility. DUPLEX materials combine the greatest energy efficiency with the highly popular modern metallic look; may also be used in creating mirror effects. TRIPLEX features natural earthtones that blend beautifully with traditional or wooden decors. EMBOSSED materials enhance decorative touch but reduces pure view out.
Interior Heat Retention All METALLIZED MATERIALS (TRIPLEX, DUPLEX, DUPLEX LOW VLT) have outstanding insulation qualities. Plastic-View heat reflective shades are virtually a "flexible duo-pane". The insulating air space between the shade and glass, and the metallization, create a "thermos bottle" effect on window. These shades are over 40% more efficient for retaining interior furnace heat than conventional window shades.
Free Solar Heating All Plastic-View shades conveniently retract to permit all of the available free solar energy to enter; then when lowered, they trap this energy inside...reducing heating requirements.
Solar Energy Rejection All METALLIZED MATERIALS: "DUPLEX ICE is the most effective, with slight drops in efficiencies in other DUPLEX, TRIPLEX, and DUPLEX LOW VLT materials. Non-metallized materials (such as UNIPLEX) are not recommended.
Daytime Privacy All METALLIZED or DARK COLOR MATERIALS. This design feature is great for creating a more spacious atmosphere; insiders can see out but outsiders cannot see in. Homes, condomimiums, recreational vehicles, etc. especially benefit from this.
Glare ControlAll METALLIZED or DARK COLOR MATERIALS. Plastic-View shades are literally like "Putting Sunglasses On A Roller". Federally specified and utilized in airport control towers worldwide.
Light ControlAll METALLIZED or DARK COLOR MATERIALS are excellent for this. Plastic-View "flexibility" allows operator to effectively manage and control how much light enters.
Sun Fade Protection (residential)All Plastic-View materials have an ultra violet (UV) inhibitor that stops up to 99% of the ultra-violet radiation. METALLIZED MATERIALS provide the best protection against sun damage, followed in efficiency by DARK COLOR materials.
Sun Fade Protection (commercial display windows)SUPER A SERIES Sputtered replaces old Amber acetate of decades ago. Permits reasonable view of merchandise.
Notes: DUPLEX MATERIALS are not recommended where heat or light reflection may be objectionable to neighbors, and definitely not to be used in situations where reflections could be a safety hazard, such as in windows that face traffic. Both motorists and pedestrians may be temporarily blinded by harsh "kick-back". DUPLEX MATERIALS are also not to be used with the following types of glass: duo-panes, chicken wire or bubble glass, etc. Intense heat relfections can place the glass in jeopardy of breaking due to the fact that it was engineered for heat loads from just one direction. For such windows, use TRIPLEX MATERIALS with a minimum of four inches back away from the glass.

Problems / Conditions
Regular Small Easy to Reach ShadesWOOD SPRING ROLLERS have been around for a hundred years and are the "standard" for small residential windows. The lowest cost.
Wood rollers are generally used on shades less that 79" in width. At these small sizes the wood spring mechanism is reliable. Maximum exposed height, 82". If both height and width dimensions exceed 72", a horizontal seam is required.
Larger Easy to Reach Shades METAL SPRING OPERATED ROLLERS by Plastic-View are special mill run rollers with several outstanding features which make them far superior than the industry standard. Safety cotter keys in end pins, silent operation, no adjustable screws or vertical lines on the shades. Plastic-View metal spring rollers have no gimmicks or "replaceable" parts, simple solid state construction which insures virtually an unlimited life expentancy. A superb piece of equipment, called for in federal specifications. Metal spring operated rollers are for areas of high humidity, and shades larger than those shown on wood spring roller charts. If both height and width dimensions exceed 72", a horizontal seam is required.
Floor to Ceiling ShadesROLLEASE BEAD & CHAIN, with the appropriate amount of chain affords convenient total control on shades of any height. If both height and width dimensions exceed 72", a horizontal seam is required.
Very High ShadesROLLEASE BEAD & CHAIN, with the appropriate amount of chain affords convenient total control on shades of any height. If both height and width dimensions exceed 72", a horizontal seam is required.
Difficult to Reach ShadesCORD & REEL, cord can be routed via cord directional change pulleys to any convenient location. This situation may also be handled with metal spring rollers on "constant tension", again, the cord may be re-routed to any location. Excellent for display windows or shades behind couches, etc. If both height and width dimensions exceed 72", a horizontal seam is required. Also consider ROLLEASE BEAD & CHAIN.
