You can find everything you ever wanted to know about our Replacement Windows right here! From learning what our windows are made of, to determining the best way to clean them, you'll find all of the answers you're looking for!What is a vinyl replacement window?
A replacement window is a window designed to fit into an existing window opening. Vinyl replacement windows are made from 100% PVC. The combined strength of the multi-chambered frames and sashes and fusion-welded corners, make vinyl windows one of the most reliable and energy efficient windows that you can purchase.
What is insulating glass?
Insulating glass consists of two pieces of glass sealed to a spacer. This creates an insulated air space between the two pieces of glass, resulting in better thermal performance. Insulated glass also reduces condensation while keeping the heat in during the winter, and heat out during the summer.
What is Low-E Glass?
Low-E (Emissivity) glass is treated with thin, virtually invisible, transparent coatings of various layers including metal oxide and silver. During the winter, Low-E glass allows the sun's natural light and short-wave heat energy to freely pass through while reflecting long-wave heat energy back inside, keeping your home warmer. In the summer, Low-E glass reflects long-wave heat energy to the outside keeping your home cooler and, reduces the penetration of the sun's ultraviolet (UV) rays, minimizing the fading of carpet and draperies.
What is Low-E Glass with Argon Gas? How does it work?
Added inside an insulating glass unit with Low-E Glass, Argon gas is an invisible, insulating blanket that replaces most of the air during the manufacturing process. With Low-E reflecting heat away, Argon gas buffers thermal transfer to enhance the performance of the entire glass unit.
What is Krypton Gas?
Krypton Gas is an inert, odorless, colorless, tasteless, non-toxic gas that is denser than air. It is used to replace air between the glass panes in an insulating glass unit to reduce temperature transfer and deter convection (heat transfer by currents that flow from a warm surface to a colder surface).
What is an R-Value?
R-value measures the resistance a material has to heat flow. The higher the R-value, the greater the resistance, and the better the insulating quality.
What is a U-Value?
U-value measures the amount of heat transferred through a material. The lower the U-value, the slower the rate of heat flow and the better the insulating value.
What is Conduction?
Conduction refers to the energy transfer from one material to another by direct contact.
How should I evaluate the energy performance of a window or patio door?
Look for the National Fenestration Ratings Council (NFRC) label on the window or patio door. This label shows the U-Value, Solar Heat Gain, visible light transmittance and condensation resistance values.

What makes a vinyl window better than a wood window?
Vinyl windows are maintenance free, never needing staining or painting, they won't rot or split and are not susceptible to termites or other wood destroying insects.
Do replacement windows reduce condensation inside the home?
Although technology has improved with the inception of warm edge spacer systems, replacement windows will not eliminate condensation inside your home. In some cases replacement windows are so energy efficient condensation may be more evident after the old drafty windows are removed. Condensation and its intensity are directly related to the humidity level inside your home and the cold temperature outside.

You can find everything you ever wanted to know about our Dream®Deck Vinyl and Composite Decking Systems right here, from learning what our decks are made of, to determining the best way to maintain them.
Why is Dream®Deck Vinyl Decking called “the Natural Replacement for Wood?”
Because compared with wood, Dream®Deck vinyl decking requires little maintenance and care. While all wood deck and dock surfaces require frequent and costly maintenance (stripping, sanding, re-nailing, refinishing, re-sealing), the only care required for Dream®Deck is regular washing. In addition, with Dream®Deck vinyl decking there are no splinters, no nails and no exposed fasteners. No rotting. No termites or other insect infestation. No hazardous chemical going into the soil. And Dream®Deck contains no lead. What could be more "natural"!
What is Dream®Deck made of?
The Dream® Deck walking surface (planks) is made of 100% PVC (polyvinylchloride), using a state of the art three-layer extrusion process. The three layers are totally weatherable. The top layer provides color uniformity and a slip-resistant surface. The second layer is recycled material for strength and environmental responsiveness. The third layer is a flexible "dual-durometer" added to the bottom of the planking to prevent the squeaking sound associated with competitive products.
Is Dream®Deck environmentally safe?
Yes. All Dream®Deck vinyl decking materials meet applicable government standards and are 100% recyclable, keeping the product out of landfills.
Is Dream®Deck slippery when wet?
The embossed pattern creates a slip-resistant surface. In fact, the Pittsburgh Three Rivers Regatta used Dream®Deck planking as a launching ramp for its "Anything-That-Floats Race," during which the surface is partly submerged. In addition, rock salt or other chemicals for snow removal do not affect the surface.
How will extremes of weather affect Dream®Deck?
It is normal for any material to expand and contract during temperature changes. Vinyl also becomes slightly less flexible in very cold weather. However, Dream®Deck design and approved installation techniques allow for these effects of temperature change.
Will Dream®Deck burn?
PVC is classified as a “self-extinguishing” material, which means it will burn only while a direct flame is applied to it.
Will the Dream®Deck surface 'chalk'?
Normal weathering, which is defined as exposed to sunlight (ultraviolet) and extremes of weather and atmospheric conditions, will cause any colored or painted surface to fade, darken, chalk or accumulate surface dirt or stains. The severity of these conditions depends on shading, air quality, pollutants, and the geographic location of the installation.
How do I keep Dream®Deck Vinyl Decking clean?
As with any product exposed to outdoor conditions, you will need to clean it to remove dirt, airborne pollution, or accidental spills. An occasional use of a household cleaner and/or hosing should suffice. For particularly stubborn stains, a solution of tri-sodium phosphate (TSP) is recommended. TSP is available at most home centers and hardware stores.
What does the Dream®Deck Warranty cover?
The warranty covers any defects in materials or workmanship in manufacture, including flaking, rotting, corroding, peeling, blistering, or splitting. Full details are spelled out in the warranty document.
Is Dream®Deck more expensive than wood?
It depends on whether you measure COST or PRICE. Here's what we mean. Although the initial investment for Dream® Deck vinyl decking may be higher than for wood, the expenses of annual maintenance and replacement will soon make the total dollar value outlay for wood higher. Your Dream®Deck representative can give you an estimated "Payback Period," based on the size and configuration of your deck. Following this period, the expense of maintaining and eventually replacing a wood deck will be higher than the entire investment in Dream®Deck.
What is Dream® Composite Decking made of?
Dream®Composite Decking is manufactured from a combination of recycled and other plastic, blended with our Purified Fiber Process (PFP)® formulation of cellulose fiber and minerals. This exclusive process enables us to create a range of durable, lightweight boards for decks and other outdoor applications.

Will Dream® Composite Decking fade over time?
Dream®Composite Deck boards are highly fade resistant and will exhibit minimal weathering over a period of years.
Why don't Dream® Composite Decking boards fade like other composites?
Most composite products are made with wood flour or chips and plastic. The Lignins found in wood products are a major contributor to fading. Dream®Composite Deck uses a Purified Fiber Process rather than wood chips as its fiber source. This process has low amounts of Lignins and consequently its Dream®Composite Deck products are more resistant to fading.
In what lengths, styles, and colors are Dream® Composite Decking boards available?
Dream®Composite Deck Traditional and Tongue & Groove boards are available in a 5/4" x 6" profile dimension. Stock lengths are 16' and 20'. Dream®Composite Deck boards can be purchased in two fade-resistant colors: Cedar and Driftwood.

What joist spans should be used when installing Dream® Composite Decking boards?
Depending on the Dream®Composite Deck board profile and application, joist spans are 16” with our Traditional and Tongue & Groove boards.
Should allowances be made for expansion and contraction of Dream® Composite Decking boards?
Yes, it is important to note that all composite and plastic-based products will experience some degree of expansion and contraction with changes in temperature. Longer boards expand more than shorter boards. See the Dream®Composite Deck Installation Instructions for more detailed installation information.
How can I cover the exposed ends of Dream® Composite Decking boards?
There are several ways in which board ends can be covered. Using the “picture frame” technique, you can run a Traditional board perpendicular to the deck boards. This covers the board ends and adds beauty and balance to the deck. You can also use Dream®Composite Deck End Caps, custom trim piece, or Dream®Composite Deck Fascia Board.
What accessories are available to finish and dress up my Dream® Composite Deck?
Dream®Composite Deck provides a number of accessories that can give your deck a more finished look, such as 12’ fascia board to cover rim joist and stair stringers, finish trim to cover the tongue of our Tongue & Groove boards.
