Casement Windows

One of the best characteristics of a casement window is the ability to tackle vulnerability to moisture. Casement windows have hinges that open vertically and are perfect for your moisture-prone rooms. This window is considered the most thermally efficient type of window as well as of the easiest to open. A casement window can give your home and space both an aesthetic appeal and greater view from the outside due to its 90 degrees hinges.

These sliding windows offer high durability and are also one of the window types that have the lowest amount of maintenance.

Picture Windows

To thoroughly enjoy the outside beauty of Denver, the best option for your home would be a picture window. One of the main and obvious reasons why it’s named a picture window is because it frames a beautiful spot or view outside your home. But picture windows also provide strong security due to their sealed shuts. Due to their large reaching structure, up to ceiling heights, picture windows also allow a lot of light to enter a room. These are a must have for homes with a picturesque view.

Geometric Windows

Geometric replacement windows are very popular for both their aesthetic appeal and their great performance. Geometric windows offer a variety of different shapes including: half-round, quarter-round, circle, trapezoid, or a custom configuration to give your home distinct character. Geometric windows can also be combined with different types of glass windows in order to maximize their efficiency and value to allow light and airflow inside your home. If you are looking for a low-maintenance window for your next replacement, then a geometric window may be a good fit for your window replacement.

Garden windows are often viewed as both charming and relaxing. The interesting architectural design of garden windows are a perfect match for displaying your plants and other special items. These energy-efficient windows are also loved for their primary purpose: to maximize sun exposure, especially in the darker months.

Bay & Bow Windows

Bay and bow windows consist of a combination of three or more windows. These can include styles such as: double-hung, picture windows, and casement windows.

Replacement Window Construction

Improving the comfort and energy use of a building are the primary factors in deciding to replace windows. Carefully consider your climate, budget, and availability, maintenance, and style of window. You should also check for durability, quality, and warranties. Check the local building department’s requirements regarding egress, safety glass, and window grade before buying. The purchase of the right windows can go far in turning a drafty home into a comfortable and more energy-efficient one.

Window Frames
For very old windows the frame and glazing had almost the same R-value (about R-1). Modern glass technology has improved the insulating performance (R-value) of the glazing itself (Typically R-3 to 8). What the frame of the window is made of has come to dominate how well the window performs overall. Modern window frames are constructed from a variety of materials including steel, aluminum, wood, vinyl, and composites such as fiberglass and epoxy resin. Each material has advantages and disadvantages.

Metal window frames are ideal for openings that require lightweight and strength. However, all metals are very good conductors of heat (R values hundreds of times less than 1). Even metal-framed windows with plastic “Thermal breaks” (a plastic strip that separates the exterior side of the frame from the room side) only improve the R-value slightly. There are no metal-framed windows currently available that are comparable in thermal performance to any of the other choices in window frames. Also, unless protected by special finishes, metal frames can oxidize (rust).

Wooden window frames are better insulating than metal frames (about R-1.4 per inch of thickness) and help to prevent cold-weather condensation problems inside the house. However wood does require maintenance (i.e. painting). If they aren’t protected from moisture, they can stick, crack, and rot.

Aluminum-clad and Vinyl-clad Wood
Some manufacturers protect their wood frames by wrapping them with vinyl or aluminum. This helps keep wood window maintenance low. However, if the cladding should come loose and expose the wood to water, it can still rot. The thermal performance is about the same as an ordinary wood frame.

Vinyl frames are primarily made from Polyvinyl Chloride (PVC). Some manufacturers fill the hollow parts of the frame with foam or fiberglass insulation. Data shows that the difference in performance between filled and hollow vinyl frames is small.

Vinyl windows are available in many styles and are generally considered low maintenance and they never need painting. However, the ultraviolet (UV) light can fade colors other than white and cause yellowing and “crazing” in cheaper construction-grade windows that are mixed with recycled plastic rather than pure “virgin vinyl”.
Pure vinyl frames are resistant to warping, shrinking, and rotting. Pure vinyl window frames are also quite strong and durable and can hold a large expanse of glass.

Frame Construction
Some windows are divided into small sections of glazing or “divided lights”. A divided light window is a considerably less energy efficient than other types because of the large number of glazing edges. However, modern multi-pane windows are often whole sheets of glass with optional plastic or wood grilles that attach to the glazing to give the appearance of a divided light window.

The insulation value of a double-pane or triple-pane window is primarily a product of the air space between the panes of glass. Spacers separate the panes at the edges. Until recently, most edge spacers were made of metal, which means the edge of the window has little or no insulating value. Many manufacturers now use improved edge seals with much better thermal performance.

Metal and vinyl frame corners may be welded or screwed together. Either one is acceptable. However, welding a corner can often distort the weather-stripping groove. Always check how well the weather-stripping meets at the corners. There must be no gaps. Wood frames are often “finger-joined” and glued to make a strong corner.

Window frames are rated A, B, or C according to their performance in an American Society of Testing and Materials (ASTM) “aging” test that involves exposure to UV light, moisture, and extreme temperatures. “A” rated windows are the best performers.

FAQ – Replacement Windows

How do I prepare my home for replacement windows?

We are very grateful if you remove curtains, blinds, or other window treatments. Security sensors should be taken down and turned off by the security company. The installation specialist should be able to see the window from the outside, and any wall decorations that are near the window’s location during installation.

Do windows usually get installed from the outside or inside?

Most windows that we replace are done from the outside. Your expert will inspect your unique situation and recommend the best process to fit your home.

What happens to my windows during this process?

We will then remove any old windows from your property and dispose of them properly after installing the replacement windows. You can request to keep your old windows by notifying the crew upon arrival.

How do you install replacement windows?

First, the glass and other working parts of the windows must be removed. The wooden frame holding the window will be left in place. Minor repairs can be made to strengthen the frame in preparation for replacement. The replacement window is installed by nailing it into place. To ensure weather resistance, the exterior casing will be formed and placed.

How often should residential windows need to be replaced?

Window replacement is a good idea for homeowners with windows older than 25 years. This will allow you to get the most out of your home’s energy efficiency, and protect your house’s “Envelope”. These are issues that require immediate attention.

It’s true that replacement windows can recoup some of their costs when they are sold?

Yes! It is a smart investment in your home. You can expect to get back almost $9,000 if you sell mid-range replacement windows that cost around $10,000. It is possible to see that this is a better return rate than bathroom remodels and upscale kitchen remodeling. It is important to remember that almost no home renovation will recover 100% of its original cost. However, 90% is a great rate to absorb.
