Infinity by Marvin® Casement Windows in Denver, CO
If you want more ventilation without sacrificing the view, an Infinity by Marvin® Casement Window may be the right solution. The sash opens outward from the side, allowing the window to open wide while keeping the glass area clean and relatively unobstructed.
Infinity Casement Windows are built with Ultrex® fiberglass and include a folding handle, multi-point locking system, and options for glass, screens, colors, and interior finishes. They are designed for homeowners who want smooth operation, low-maintenance materials, and a window that closes firmly against the frame.
Gravina’s Window Center of Littleton® has helped Colorado homeowners replace their windows since 1973. As Colorado’s oldest authorized Infinity by Marvin® dealer, we evaluate more than the size of the opening. We also consider exterior clearance, room layout, airflow, architectural style, and installation conditions before recommending a casement window.
Are Casement Windows a Good Choice for Colorado Homes?
Casement windows can be a strong choice for Colorado homes because they combine ventilation, visibility, and a sash that is pulled toward the frame when the window is closed and locked.
Homeowners commonly consider casement windows when they want:
- A wide, relatively unobstructed outdoor view
- Ventilation from a single operating sash
- A window that can help catch and direct passing breezes
- Handle operation instead of lifting or sliding a sash
- A clean appearance without the horizontal meeting rail found on hung windows
The right window style still depends on the location. Because a casement sash opens outward, the exterior must remain clear of shrubs, walkways, decks, rooflines, railings, shutters, and other possible obstructions.
What We Have Learned Installing Casement Windows in Colorado
After working with Colorado homeowners for more than five decades, we have found that casement windows are often a strong fit when ventilation, operating ease, and a broad glass area are priorities.
They are frequently considered above kitchen counters and sinks because the folding handle may be easier to reach than the lower rail of a hung window. They can also work well beside picture windows when a homeowner wants ventilation without substantially interrupting a larger view.
The outward-opening sash must be evaluated carefully. Before recommending a casement window, our team considers nearby walkways, decks, landscaping, exterior trim, roof overhangs, and other conditions that could interfere with operation.
Installation alignment is also important. Casement windows depend on properly aligned hinges, operating hardware, and locking points. A replacement window that is not positioned correctly within the opening may become more difficult to operate or lock.
Why Choose Infinity by Marvin® Casement Windows?
Infinity Casement Windows are constructed with Ultrex® pultruded fiberglass. According to Infinity by Marvin®, Ultrex® is designed to resist expansion and contraction as outdoor temperatures change.
That dimensional stability is relevant in Colorado, where windows can experience strong sunlight, freezing temperatures, snow, wind, and large changes between daytime and nighttime temperatures.
Available Infinity Casement Window features include:
- Ultrex® fiberglass frame and sash construction
- A broad glass area for outdoor visibility
- A folding operating handle
- A multi-point locking system
- A standard Easy Wash® hinge
- Multiple glass, screen, color, and interior finish choices
- Custom sizing for replacement-window openings
Product options and configurations may vary by window size and project requirements. Our team confirms current availability during the consultation and ordering process.
How Do Infinity Casement Windows Operate?
A casement window is hinged along one vertical side. Turning the operating handle moves the sash outward and allows the homeowner to control how far the window opens.
This style can be useful in locations where lifting or sliding a sash would be inconvenient. Above a kitchen counter or sink, for example, the operating handle may be easier to reach than the bottom rail of a single-hung or double-hung window.
The folding handle tucks closer to the frame when it is not being used, helping reduce interference with many blinds, shades, and other window treatments.
Are Infinity Casement Windows Easy to Clean?
Infinity Casement Windows include the Easy Wash® hinge. The hinge is designed to move the sash away from the frame and provide greater access to the exterior side of the glass from inside the home.
This can make routine cleaning more manageable, particularly in locations where exterior ladder access would otherwise be required. Actual reach and accessibility depend on the window’s size, installation height, surrounding trim, and location within the room.
Homeowners should follow the manufacturer’s current care instructions. Mild soap, warm water, and a soft cloth are generally preferable to abrasive pads or harsh cleaning products.

How Secure Are Infinity Casement Windows?
Infinity Casement Windows use a multi-point locking system. Instead of securing the sash at only one location, the locking hardware engages at multiple points and draws the sash toward the frame.
This design helps the sash close consistently against the frame and supports the completed window’s weather seal.
No window should be described as burglar-proof. Window security depends on the complete assembly, including the frame, glass, locks, surrounding construction, installation, and proper homeowner operation.
Are Casement Windows Energy Efficient?
Casement windows can provide effective air-sealing performance because the sash is pulled toward the frame when the locking system is engaged. However, window style is only one part of overall energy performance.
During a consultation, we consider factors such as:
- The direction the window faces
- Morning or afternoon sun exposure
- Existing trees, overhangs, and exterior shading
- The size of the glass area
- The room’s current comfort problems
- Concerns about heat gain, fading, glare, or winter comfort
- The glass packages currently available for the selected window
The appropriate glass option should be selected for the opening and the homeowner’s priorities rather than assumed from the window style alone.
What Screen Options Are Available?
Because a casement sash opens outward, the insect screen is positioned on the interior side of the window.
Infinity offers screen choices that may include:
- Bright View screen: The standard screen option uses fiberglass mesh with an aluminum surround.
- Hi-Transparency screen: A finer mesh option designed to improve visual clarity and airflow while helping protect against smaller insects.
An EverWood®-wrapped screen option may also be available for homeowners who want the screen surround to coordinate with an EverWood® interior finish.
Screen names, materials, colors, and availability may change. Our team confirms the current options for the selected window configuration.
Can Casement Windows Have a Wood-Look Interior?
Homeowners who appreciate the appearance of stained or painted wood can consider the optional EverWood® interior finish.
EverWood® is an engineered interior material designed to resemble natural woodgrain. It can be finished to coordinate with interior trim, cabinetry, flooring, and other architectural features.
EverWood® is an interior finish applied to the Infinity window rather than a traditional exposed wood window frame. It gives homeowners the opportunity to create a warmer, wood-look interior while retaining the Ultrex® fiberglass structure.

Where Do Casement Windows Work Best?
Casement windows can work in many areas of a home, including:
- Above kitchen counters or sinks
- Living rooms where a broad view is important
- Bedrooms when the selected unit meets applicable egress requirements
- Home offices
- Bay and bow window assemblies
- Rooms where additional ventilation is desired
- Narrow or vertically proportioned openings
- Contemporary window combinations with large picture windows
Casement windows can be installed individually or combined with fixed windows to provide ventilation alongside a larger glass area.
When Might a Casement Window Not Be the Right Choice?
Casement windows are versatile, but they are not the right choice for every opening.
A different window style may be more appropriate when:
- The sash would open into a walkway, patio, deck, or occupied outdoor area
- Shrubs, trees, or landscaping would interfere with outward operation
- The opening is directly beneath a low roofline or overhang
- An exterior railing or architectural feature limits sash movement
- The homeowner needs to use a window-mounted air-conditioning unit
- A sliding or hung-window appearance better matches the home
- The required emergency escape opening cannot be achieved with the proposed size
Our Design Consultants evaluate the existing opening, exterior clearance, room use, and homeowner priorities before recommending a window style.
Can Casement Windows Be Used for Bedroom Egress?
Some casement-window sizes and configurations may meet applicable emergency escape and rescue opening requirements. Compliance depends on factors such as the clear opening width and height, net clear opening area, sill height, window location, and the building codes adopted by the local jurisdiction.
A product label or window style alone does not confirm egress compliance. The specific opening and proposed unit must be evaluated individually.
Why Installation Matters
A well-made casement window still depends on accurate measurement and proper installation. The replacement unit must be positioned correctly so the frame remains square, the sash operates smoothly, and the locking points align as intended.
Our in-house window and door installation crews complete the installation work for the replacement windows and doors we sell. Depending on the project scope, the installation process includes:
- Reviewing the existing opening and surrounding conditions
- Removing the existing window included in the project scope
- Positioning and securing the replacement unit
- Checking that the frame is square and properly supported
- Insulating and sealing the perimeter of the window
- Testing sash movement, hardware, and lock alignment
- Reviewing basic operation and care with the homeowner
A frame that is twisted, bowed, or improperly supported can affect handle operation, sash alignment, locking, and long-term performance.
The window matters. The install is the difference.

Frequently Asked Questions About Casement Windows
What is a casement window?
A casement window has a sash hinged along one vertical side. A handle opens the sash outward in a motion similar to a door.
Do casement windows provide good ventilation?
Casement windows can open wide and may help catch passing breezes. Actual airflow depends on the direction of the hinge, the window’s location, nearby buildings, landscaping, and weather conditions.
Are casement windows energy efficient?
Casement windows can provide effective air-sealing performance because the locking system pulls the sash toward the frame. Overall performance also depends on glass selection, window size, orientation, installation, shading, and surrounding construction.
Can casement windows meet bedroom egress requirements?
Some sizes and configurations may meet applicable emergency escape and rescue opening requirements. Compliance depends on the specific unit dimensions, clear opening, sill height, installation location, and locally adopted building codes.
Can Infinity Casement Windows be cleaned from inside?
The Infinity Easy Wash® hinge is designed to provide greater access to the exterior side of the glass from inside the home. Actual accessibility varies by window size, location, installation height, and surrounding trim.
Do casement windows have screens?
Yes. Because the sash opens outward, the insect screen is installed on the interior side. Infinity screen choices may include the standard Bright View screen and an optional Hi-Transparency screen.
Can I place blinds or shades over a casement window?
Yes. The folding handle tucks closer to the frame and may reduce interference with many window treatments. Clearance should still be confirmed before selecting blinds, shades, shutters, or other coverings.
Are casement windows good above a kitchen sink?
They can be. The operating handle may be easier to reach across a counter or sink than the lower rail of a hung window. The opening should still be evaluated for handle reach, window height, and exterior clearance.
How long are Infinity Casement Windows covered by warranty?
Infinity products are covered according to the terms of Infinity’s Limited Lifetime Warranty. Gravina’s Window Center of Littleton® separately provides a lifetime workmanship warranty covering our installation work. The applicable written warranty documents control all coverage terms and exclusions.
