    Anti Glare Airtight Air Infiltration Plastic Frame For Door Glass Energy Efficient

    I feel no contradiction between science and art. With this panel, I wanted to get away from classical stained glass ideas, and to express a kind of counterpoint between the rational and the intuitive. I started with a linear geometric idea in the lower section, the kind of comfortable repetitions of squares and rectangles that would have made Frank Lloyd Wright happy. I was thinking of telescopes and microscopes and petri dishes when I drew the circle up above. Some of the most beautiful, mysterious and awe-inspiring images of recent years have come from astronomers, biologists and physicists. Within the circle, I drew lines growing like tendrils, or the complex re-curving forms of higher mathematics. I chose colors that feel organic and biological, and I wanted them to float in space.
    Arts Sciences evening viewThe motif of a twisting ribbon is something I borrowed from the great Art Nouveau designers of the nineteenth century. The idea of continual change is implied by the fact that every time the ribbon turns over, it reveals a new color. The energy and visual momentum of the lead lines is also important. Once the eye starts to follow a line, I sometimes continue that line beyond its normal end point in a false lead, using the energy like a wave or a growing form.
    The clear beveled glass components will spill prismatic rainbows into the room where it is hung. Because of the antique mouth-blown glass, the circular part of this window will project an image of itself on the floor. The panel is framed in zinc channel for a clean, contemporary look.

    You’ve selected the custom frame you want to display your precious artwork or photo, but then you realize something: There are multiple choices for covers, and you want to know which type and variety would suit your needs and price range best.
    In the guide below, we’ll walk you through a few basic steps you should know about covers for picture frames.
    The cover (or “glazing material”) is a key part of any frame– custom or otherwise– as this is what allows you to see your special art or photo inside. Just as the backing material of your frame needs to preserve the integrity of your art, the cover should not only allow you to clearly view it, but also protect it from outside forces.

    We use acrylic in all of our frames. Our acrylic is more expensive than glass, but it is beautifully clear (regular glass has a green tint), much less likely to shatter, and offers increased UV protection. Because we are shipping your art, we know the safest option is to protect your art using acrylic.

    Our acrylic is not completely anti-glare, but it's the highest quality and has a really natural level of reflection that all of our customers have been really pleased with!

    Our acrylic manufacturer has tested our acrylic as protective against 87-89% of UV rays (significantly more than traditional glass).

    WINDOWS FRAMES
    Homeowners purchasing energy-efficient windows should also consider the thermal performance of the window frame. Inefficient window frames lose significant amounts of heat and are a prime cause of condensation on the glazing. The design of a window frame and the materials used in its construction determine its performance. Window frames come in many architectural styles, and are constructed from a wide variety of materials.
    WHOLE WINDOWS RATINGS
    When you compare energy-efficient windows, the first thing to consider is the window's R-value. The R-value is a measure of the window's thermal resistance to heat conduction. A window with a high stated R-value (or a low U value) should be energy-efficient. When window manufacturers tell you the R-values of their windows, they usually give the center-of-glass value, which is considerably higher than the whole window rating. Whole window ratings, introduced in 1989 by the National Fenestration Ratings Council (NFRC), reflect the insulating value of the glass, the sash (where applicable), and the frame. The Energy Policy Act of 1992 (section 121) required that the NFRC develop, with industry cooperation, a national standard testing procedure, as well as labeling rules. The new labels use U-values (Btu/hr-ft2-oF) which are a measure of thermal conductivity. The U-value is the reciprocal of the R-value (R=1/U). For example: if R = 4, then U = 1/4 or 0.25. These performance ratings will probably become national standards in the near future. The NFRC is also investigating methods for rating windows according to solar heat gain, air infiltration, and condensation potential. Other NFRC investigations seek methods to compare the heating and cooling performance of windows using separate ratings.
    ARCHITECTURAL STYLE AND AIR FILTRATION
    The architectural style of a window effects the amount of air infiltration (leakage) through the window. Air infiltration is measured in cubic feet per minute of air leakage per linear foot of crack (cfm/ft.or cm2/lmc) or per unit of area (cfm/ft2 or cm2/m2). The quality of the window frame material and the installation and the use of caulking and weather-stripping also effect air leaks. There are six common architectural styles for window frames: fixed-pane, casement, awning, hopper, double-hung, and slider windows.
    Fixed-pane windows, when correctly installed, are usually the most airtight and least expensive type of window. They cost about 15% less than operable windows of the same size. They come in many shapes, such as rectangular picture windows, oval tops, circle tops, and triangular view windows. Because these windows cannot open, they are not suitable for rooms that require ventilation.
    Good quality casement, awning, and hopper windows are moderately airtight and open easily for ventilation. Casement, awning and hopper windows have hinges on the side, top, and bottom, respectively. These windows are more airtight than other operable windows because the latching mechanism draws all four edges tight against plastic, compression-type gaskets or seals. Windows with compression seals allow only about half as much air leakage as windows with sliding seals, such as double-hung and slider windows.
    Double-hung windows have a top and bottom sash (sliding section of the window), and open by pulling up on the lower sash or down on the upper one. Although they are the most popular type of window, they are one of the most inefficient if they do not seal tightly. Slider windows are similar to double-hung windows, except that they move horizontally, rather than vertically. They are especially suitable for spaces that require a long, narrow view. Sliders, however, have a well-deserved reputation for air leaks.
    Materials for Window Frames
    The frame's material effects how much heat the window loses and how much moisture condenses around the window. Window frames are constructed from a variety of materials including aluminum, wood, vinyl, composites, and fiberglass. They may consist of one material or a combination of two different materials, such as wood and vinyl. Each material has advantages and disadvantages; as discussed below.
    Aluminum Window Frames
    Aluminum window frames are strong, but lightweight. They are ideal for openings that require customized frames. They can hold large, heavy, or odd-sized panes of glass. Frames made exclusively from aluminum, however, are not as energy-efficient as other frames. Aluminum frames often account for large amounts of heat loss, and contribute to condensation around the edge of the pane and on the frame. New aluminum frames usually have thermal breaks, which are insulating plastic strips between the inside and the outside of the frame and sash. Thermal breaks improve the R-value of aluminum windows, although the most basic aluminum window with thermal breaks still may not be the best choice for cold climates.
    In some of the more advanced aluminum windows, the thermal break is combined with foam insulation to create a super energy-efficient frame. One window manufacturer produces an aluminum frame with foam insulation that has a frame R-value of about R-5.6. When combined with high-efficiency glazing, the window has an overall R-value of R-6.3.
    Because they corrode easily, aluminum window frames may be a poor choice for those who live near the seashore or in heavily polluted areas. You can paint aluminum frames, although they need special coatings to ensure an attractive, long-lasting finish.
    Wooden Window Frames
    Wood window frames are still the choice of most homeowners and most major window manufacturers. Wooden window frames have a higher R-value than aluminum and may have a more traditional look. Temperature extremes do not effect them, and condensation is less common because the inside of the frame stays relatively warm. Since they are easy to paint, wooden window frames also allow the consumer to change the color of the window. Wooden window frames, however, require considerable maintenance, including periodic painting. If they are not protected from moisture, they can stick, crack, and warp. As the cost of wood increases, manufacturers have begun using veneers over lower grade wood or strandboard cores. While these are not solid wood, the wood fiber determines the performance of the frames if the percentage of resin is less than 5%.
    Aluminum-clad and Vinyl-clad Wooden Frames
    Vinyl-clad and aluminum-clad wood frames are wood frames covered on the exterior with either vinyl or aluminum. This allows the homeowner to have the higher R-value and traditional look of the wood frame indoors, while avoiding periodic painting outdoors. These window frames, however, may rot if the cladding leaks and moisture reaches the wooden frame.
    Wood-Plastic Composites
    Several companies produce window frames made from wood scraps, vinyl waste, polyethylene, and other recycled products. They may contain as little as 50% wood fiber. The advantages of composite frames are strength and resistance to moisture. Although made from recycled products themselves, the mixture of materials used to make composites makes them difficult to recycle.
    Vinyl Window Frames
    Vinyl window frames have become a popular option, especially for consumers who want to replace old window frames or install windows in unconventional openings. Vinyl window frames are primarily made from polyvinyl chloride (PVC), a relatively flexible material that allows them to be easily customized to fit almost any opening. Vinyl window frames are available in a wide range of styles and shapes.
    Vinyl window frames offer many advantages because they require little maintenance and mold easily into almost any shape. The thermal performance of vinyl windows depends on the type and quality of the window. At least one manufacturer produces frames filled with foam insulation. Computer calculations and at least one laboratory test suggest that the R-value difference between foam-filled and hollow vinyl windows adds little to the overall window energy performance.
    Vinyl frames do not need to be painted because the color is uniform throughout. They do not swell, shrink, peel, or corrode, which make them ideal for homes and businesses near the ocean or in heavy industrial areas. Vinyl window frames are one of the best options for remodeling projects, because the manufacturer fabricates the frames to the specified dimension of the opening. This ensures that the windows will fit tightly in the opening, reducing heat loss and condensation. Dealers can usually install replacement windows in one or two days. Vinyl window frames are also competitively priced.
    Because of the nature of the material used, vinyl window frames also have disadvantages. For example, they are not inherently strong or rigid. The flexible qualities of PVC also limit the size of the frame and the weight of the glass used in it. Some vinyl frames are reinforced with metal to compensate for these limitations, but this lowers their R-value. Vinyl window frames can soften, warp, twist, and bow if heat builds up within the frame. Moreover, the color of the window frames may fade over time. One manufacturer offers a new type of vinyl frame that is more resistant to distortion and discoloration from the sun and heat. In hot climates, ordinary vinyl windows are only sold with white frames, to limit solar heat absorption. Because this new material tolerates higher temperatures, this will allow it to be available in more colors for hot climates.
    When purchasing vinyl windows, you may also want to consider certain other qualities of window frames. For example, window frames with corners that are welded together with heat (often referred to as fusion- or heat-welded) are usually more durable than frames with plastic corner gussets or corner keys, or those that are glued together (solvent-welded). You can paint vinyl window frames with special paints, but you should make sure that painting the vinyl does not violate the frame manufacturer's warranty. You should also beware of dealers who claim that they have windows in stock and can alter the opening to accommodate the new window. The window frame may not fit properly, and the added cost for labor may exceed the cost of a customized window frame.
    Fiberglass Window Frames
    Fiberglass window frames are a relatively new type of frame made of fiberglass composite material. Some of these window frames are hollow; others are filled with fiberglass insulation. Most are prefinished with a white or brown polyurethane coating. These window frames are manufactured using a process called "pultrusion." Glass matting and continuous glass strands are pulled through a tub filled with resin. The window frames are then formed in a preformer and pulled into a heated die. A chemical reaction hardens the material.
    Fiberglass is an excellent insulating material. In addition, fiberglass window frames do not warp, shrink, swell, rot, or corrode. They do not soften and degrade under the thermal conditions that most windows are exposed to, and they require virtually no maintenance. Fiberglass window frames are also relatively strong and durable, and can hold a large expanse of glass. You can specify almost any color you desire. You can also paint them.
    Although fiberglass may be the window frame of the future, there are a few disadvantages. They may not be widely available. Currently, only a few companies manufacture them, and the long-term performance is still unknown. Fiberglass window frames also cost more than the other types of window frames. Dark-colored fiberglass frames can also fade. Consumers should not use harsh or abrasive cleaning agents on the sash and frame, as they can fade, discolor, or physically weaken the material. Also, insulated window coverings, shutters, and other shading devices, as well as direct applications of certain films to the surface of the glazing, may cause thermal stress and adversely effect the thermal performance of the window.
    FRAME CONSTRUCTION
    Traditional windows are divided into smaller sections (or "lights") by muntins. These are small framelike dividers or grilles. When they truly divide the window, there is a considerable energy penalty caused by the increased edge area. Most manufacturers use removable plastic or wood grilles that clip onto the inside of the sash. Some manufacturers obtain a traditional look, without losing energy, by gluing muntins to both sides of the window.
    The insulation value of a double-pane or triple-pane window is primarily a product of the still air space between the panes of glass. Spacers separate the panes at the edges. Until recently, most edge spacers were made of square metal tubing, usually aluminum. Metal edge spacers are easy to manufacture and easily formed to various window shapes. Unfortunately, metal conducts heat extremely well. In a window with metal edge spacers, this means that the edge of the window has little or no insulating value. The temperature of the inside pane of glass in this area will be very close to the temperature of the outside pane. The colder edges can cause heat to escape and condensation to occur along the window edges.
    Recently, several manufacturers have introduced edge spacers with increased insulation values. The alternative edge spacers come in a variety of forms. By using reduced metal thickness, a less conductive metal (such as steel), and by changing the geometry of the spacer from a "D" shaped tube to a "U" shaped channel, some manufacturers have been able to get increased energy efficiency from edge spacers without having to retool their production machinery. Other alternatives include using two layers of rubber with a thin piece of metal sandwiched in between for structural rigidity, or using other materials such as foam or fiberglass with no metal at all. One of the most effective new edge spacers uses both approaches. A thin layer (1/8 inch or 0.3175 cm.) of rigid polyurethane foam separates two steel spacers. This type of spacer boosts the overall energy performance of a typical window by 20% over one using a standard aluminum spacer.
    Although welded corners provide the most durable, watertight seal, windows with plastic or urethane thermal breaks cannot be welded. They use a mechanical fastener or bracket in conjunction with gaskets and/or sealant Argon gas-filled windows use a dual seal method. Polybutylene is the most common primary seal and prevents gas leakage from between the panes. A secondary seal of silicon holds the spacer in place and protects the primary seal from moisture degradation. Seals can be damaged during transport or installation. They can also degrade from exposure to sunlight, pooled water, or chemicals. Window units are rated A, B, or C according to their performance in an ASTM "aging" test that involves exposure to Ultraviolet (UV) light, moisture, and extreme temperatures. "A" rated windows are the best performers.
    SUMMARY
    Energy efficiency is an important factor when purchasing windows for your home, or when replacing old windows. Windows with energy-efficient frames can enhance the thermal performance of the opening, and the entire home as well. You should carefully consider the needs for your home, the climate in your area, your budget, the availability of the windows, required maintenance, and the qualities of the window frame. You should also check for durability, quality, warranties, and cost-effectiveness. The purchase of the right window can turn your drafty home into a warm, cozy, energy-efficient one. The installation of windows should be done after careful research and planning.
