Style: Casement, Double-Hung, Sliding, Picture, Bay, Bow, Awning
Window Styles to Choose From
Different window styles serve different purposes depending on ventilation needs, room layout, and architectural style. During your consultation, we’ll help you compare styles and determine what works best for your home.
Casement Windows
Casement windows are hinged on the side and open outward using a crank handle. They provide excellent ventilation and a tight seal when closed.
Often chosen for:
- Areas where airflow is a priority
- Kitchens, bathrooms, and hard-to-reach spaces
- Homes seeking strong energy performance
Double-Hung Windows
Double-hung windows feature two operable sashes that move up and down, allowing for flexible ventilation and easy cleaning.
Often chosen for:
- Traditional and historic homes
- Bedrooms and living spaces
- Homeowners who want classic style and functionality
Sliding Windows
Sliding windows open horizontally and are ideal for spaces where vertical opening is limited.
Often chosen for:
- Wide window openings
- Modern or transitional homes
- Rooms where ease of operation matters
Picture Windows
Picture windows are fixed windows designed to maximize natural light and views. Because they do not open, they offer excellent energy efficiency.
Often chosen for:
- Living rooms with scenic views
- Spaces where ventilation is not needed
- Paired with operable windows for balance
Bay Windows
Bay windows extend outward from the home and typically combine multiple window units to create additional interior space and visual interest.
Often chosen for:
- Living rooms and dining areas
- Homes looking to enhance curb appeal
- Creating seating or display space
Bow Windows
Bow windows are similar to bay windows but use four or more windows in a curved configuration, creating a softer exterior appearance.
Often chosen for:
- Homes with curved or softer architectural lines
- Expansive views and added natural light
- Elegant, design-forward spaces
Awning Windows
Awning windows are hinged at the top and open outward from the bottom, allowing ventilation even during light rain.
Often chosen for:
- Bathrooms and basements
- Placed above or below other window styles
- Areas needing privacy and airflow
Materials: Wood & Clad, Fiberglass, Vinyl
Window Material Options
Each window material option offers distinct advantages depending on your home’s style, performance needs, and budget. During your consultation, we’ll walk through these differences and help you select the best solution.
Wood & Clad Windows
Wood and clad windows combine classic interior warmth with durable exterior protection. Interior wood provides rich aesthetics and design flexibility, while exterior cladding helps protect against weather and reduce maintenance.
Benefits
- Timeless appearance, painted or stained
- Excellent insulation and comfort
- Cladding that resists rot, fading, and weather
- Broad design flexibility
Best for
Homeowners prioritizing design, craftsmanship, and long-term curb appeal.
Fiberglass Windows
Fiberglass windows are known for exceptional strength and stability. Because fiberglass expands and contracts at nearly the same rate as glass, seals remain tighter and performance stays consistent through temperature changes.
Benefits
- Extremely strong, stable construction
- Excellent energy and thermal performance
- Low maintenance with long-lasting finishes
- Slim profiles that allow for more glass and light
Best for
Homeowners focused on durability, efficiency, and long-term performance.
Vinyl Windows
Vinyl windows offer a practical, cost-effective solution with reliable insulation and easy upkeep. Modern vinyl windows are engineered for durability and consistent performance across a wide range of home styles.
Benefits
- Affordable replacement option
- Low maintenance with no painting required
- Good insulation and energy efficiency
- Dependable performance for everyday living
Best for
Homeowners seeking value, comfort, and minimal maintenance.
Glass Technology: Insulation, Light Transfer, Gas Fills
Window Glass Technology
Modern window performance depends as much on the glass package as it does on the frame. Today’s windows are rated using standardized performance values.
Low-E (Low-Emissivity) Glass
Low-E glass uses a nearly invisible coating to reflect heat while still allowing natural light to pass through. Most quality replacement windows today include some form of Low-E glass because of its impact on comfort and efficiency.
Values
- Low-E is usually listed as a feature rather than a number value.
- Different Low-E coatings may be used depending on whether the goal is better insulation, reduced solar heat, or a balance of both.
What it means for your home
Low-E glass helps keep heat inside during winter, reflect heat away during summer, and block ultraviolet rays that can fade flooring and furniture.
U-Factor (Insulation Performance)
U-Factor measures how well a window resists heat transfer. Lower numbers indicate better insulation.
Values
- Older or basic windows: around 0.40 to 0.50
- Standard replacement windows: around 0.30 to 0.35
- High-performance windows: 0.20 to 0.29
What it means for your home
Lower U-Factor values help reduce heat loss, drafts, and cold spots, especially during winter. Many homeowners notice more even temperatures near windows with lower U-Factor ratings.
SHGC (Solar Heat Gain Coefficient)
SHGC measures how much heat from sunlight passes through the window glass. It focuses specifically on solar heat, not overall insulation.
Values
- Lower solar gain: 0.20 to 0.30
- Moderate solar gain: 0.30 to 0.40
- Higher solar gain: 0.40 and above
What it means for your home
Lower SHGC values help limit overheating in sunny rooms, while moderate values can allow beneficial warmth during cooler months. The right range depends on window orientation, room usage, and personal comfort preferences.
Argon & Krypton Gas Fills
Many energy-efficient windows use argon or krypton gas fills between panes of glass to improve insulation. Argon is commonly used and provides strong insulation at a reasonable cost. Krypton is denser and typically used in higher-performance or thinner glass units where additional insulation is needed.
Values
Gas fills are usually listed as a feature, such as “argon-filled” or “krypton-filled,” rather than as a numerical rating.
What it means for your home
Gas-filled glass units insulate better than air-filled units and contribute to lower U-Factor values, helping maintain more consistent indoor temperatures and improved comfort.
Visible Light Transmittance (VLT)
In addition to efficiency and insulation, the amount of natural light a window allows into your home plays a major role in comfort and livability. Visible Light Transmittance, or VLT, measures how much daylight passes through the glass.
Values
- Higher light transmission: 0.50 to 0.70
- Moderate light transmission: 0.40 to 0.50
- Lower light transmission: below 0.40
What it means for your home
Higher VLT allows brighter interiors, while lower VLT can help reduce glare in very sunny spaces. A balanced VLT provides comfortable daylight without excessive brightness or heat.

Newark Windows: What Makes This Market So Special
Newark is a college town with a housing stock that spans three centuries, and that mix shapes almost every window project we take on. Downtown, near Main Street and the University of Delaware, you will find 1700s and 1800s colonials where homeowners want replacements that hold the historic proportions and divided-light look. A few blocks out, the ranches, Cape Cods, and split-levels that went up during Newark’s 1950s and 1960s growth boom are now at the age where original aluminum and first-generation vinyl windows have lost their seals. And in the brick-and-vinyl colonial subdivisions built through the 1980s and 1990s, around Brookside, Fairfield, and Nottingham Green, the common request is full-home replacement with low-E glass for comfort and energy savings.
Two things make Newark specific. First, the University. A large share of homes near campus are rentals, so owner-occupants in the surrounding neighborhoods care a lot about curb appeal and resale, and replacement windows are one of the highest-return upgrades in both the Christina and Red Clay school districts. Second, the climate. Sitting where the Piedmont meets the coastal plain near White Clay Creek, Newark gets damp, freeze-thaw winters followed by humid summers, the exact cycle that breaks down old seals and swells wood sashes.
When you book a free in-home consultation, we measure your actual openings and walk you through Marvin and ProVia options suited to your home’s age and style.

The Approach
This Newark home is a classic two-story colonial, brick on the first floor with vinyl siding above. The original windows had reached the end of their service life, with drafty sashes, tired seals, and a dated look that held back an otherwise well-kept exterior. The homeowners wanted better energy efficiency, a cleaner and more current appearance, and windows that wouldn't need attention again for decades.
We replaced the windows throughout with ProVia units, including double-hungs across both floors and a three-section picture window flanked by double-hungs on the main level. Colonial grilles keep the traditional look the home's architecture calls for, while low-E insulated glass handles Newark's freeze-thaw winters and humid summers.

What Homeowners Say About Our Window Installations
I recently had a Provia Door installed by Russ from Spring House. I was very impressed with the hard work and high quality of the installer, Russ. I appreciated the attention to detail and the door is beautiful. I would recommend Eric and his team from Hockessin.
Eric and his crew did a great job installing our 2 new sliding doors. Fixed the trim and cleaned up well! Doors look great 🙂
Thanks Eric and crew!
Spring House replaced all of my windows. My new windows are easy to operate; they are also well insulated and functional. I replaced my kitchen window with a casement window and it my favorite window in the entire house. From the initial sales appointment to the day of installation, everything worked seamlessly.
I recently had them back to install a new front door with matching storm door. My home has the best curb appeal. I love my front door. Great products and services, you will not be disappointed.
Spring House provided and installed my new front door entry system. The entire process went smoothly, the installation was outstanding and the price beat all other bidders. All of the employees were great to deal with and I highly recommend Spring House!
I generally do not leave reviews but felt compelled to do so , i have been working with Eric replacing windows in my home over the last 12 years and his men just completed the last window installation . They did an outstanding job very professional and personable , over the years there were some problems but one call to Eric and problems were solved . He stands 100 percent behind what he sells and installs .

Common Questions from Newark Homeowners
Is there still a federal tax credit for replacement windows?
The federal Section 25C energy-efficient home improvement credit for windows expired on December 31, 2025, so replacements installed in 2026 are no longer eligible. We can still help you choose ENERGY STAR rated windows that lower your energy bills, and we will let you know about any current manufacturer or utility rebates.
How long does a window replacement take?
Most Newark homes are completed in one to two days, depending on the number of openings. We confirm the timeline at your in-home consultation.
Is painting included?
Products can be ordered factory-finished, and we handle all the capping and exterior trim work of your project. We do NOT paint interior trim. We will replace your existing trim with primed trim, but the homeowner will need to paint that primed trim (or hire a painter) once installation is complete.
How is disposal handled?
We pack in and pack out each day, leaving your home as clean as we find it. All debris and old materials are hauled away by our local crews and disposed of in our own dumpsters at our warehouse.
What window brands do you install?
Our Hockessin showroom specializes in Marvin, ProVia, and Vytex. We are not a single-brand installer, so we match the window to your home and budget.
Can I reuse my current door hardware?
It depends on the brand of your existing hardware. Certain door manufacturers pair better with certain hardware brands, so during your free consultation we’ll review your existing hardware and confirm what’s compatible with the door brand you’re considering.
Do I need a permit to replace windows in Newark?
Newark requires a licensed contractor for window replacement, and a permit is generally required for exterior work. Whether your home falls under City of Newark Code Enforcement or New Castle County Land Use depends on whether it sits inside city limits. We confirm the right jurisdiction for your address and handle the permit coordination.
Will new windows help with Newark's weather?
Yes. Newark’s freeze-thaw winters and humid summers are hard on older single-pane and early-vinyl windows. Modern low-E insulated glass and proper installation cut drafts and condensation and stand up to the mid-Atlantic’s swings.
