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.

Norristown Windows: What Makes This Market So Special
Norristown is not a typical Montgomery County suburb. As the county seat, it sits on three hills that slope down to the Schuylkill River, and its streets are laid out on a dense, walkable grid that gives it more of a city-block feel than the townships around it. That layout shows up in the housing stock. Downtown blocks are lined with Victorian rowhouses and twins and early-1900s foursquares, while the outer sections and the adjacent Norriton townships fill in with mid-century capes, ranches, and colonials.
A lot of those homes still have their original or first-generation windows. In older single-pane and early double-pane units, the seals have usually failed and the sashes leak air, which is exactly why so many Norristown owners feel it on their energy bills. Replacing tired windows is one of the most direct ways to cut that monthly waste, and as you plan around the cooling season it is worth knowing what new windows actually cost in our area before you commit.
Two local factors shape the work here. Norristown has local historic districts with an active Historical Architectural Review Board, so on many older blocks any exterior change visible from the street, including window style, profile, and grille pattern, is reviewed for appropriateness before it goes in. The second factor is moisture. The lower neighborhoods near the Schuylkill live with it year round, and the river set an all-time record crest at Norristown during Hurricane Ida in September 2021, topping the 1972 Agnes record. That humid riverside air is hard on window seals over time, so we choose products and installation methods with it in mind, and we handle the Municipality’s contractor registration and any historic-district review so you do not have to.

What Homeowners Say About Our Window Installations
I’ve used Spring House Window & Door several times for window replacement at my house. It was helpful for me to be able to go to their showroom and to see and try out the windows they recommended. It’s been about 6 years since the windows were installed and they still look good, open and close smoothly and are easy to clean. I highly recommend Spring House WIndow & Door.
Purchased a fiberglass slider from them. The install guys did a beautiful job working seamlessly together. The door is solid and well crafted. Would use them again. Very happy!
We got our new door by Springhouse and I love it. We will save a ton of money on just the heating. In addition it looks awesome. Our house is 100 years old and Zack Keller did a fabulous job doing the project right. Would highly recommend both Springhouse and Zack.
The gentleman came out and measured and was very professional. he gave me the brochure for the products that they carry. I knew exactly what I wanted and he assured me it would be delivered in a timely fashion. After following up with someone on the sales team they realized there was a mistake and the doors had been delivered and were sitting in the warehouse. no big deal because they came and spent half a day installing three identical doors. I was told by the installer if there was something wrong or an issue came up that they would come back and fix it. It is an older home that I live in and one of the doors just wasn’t closing correctly. An appointment was made and the service technician came out and now the door closes perfectly. I would recommend Spring House doors to anyone who is looking for quality and service. I will use them again for future projects.
Great job replacing a front door unit assembly that included sidelines and custom transom. Terrific price and very skilled install team. A+++

Common Questions from Norristown Homeowners
Do I need a permit to replace windows in Norristown?
Often not. Under the Pennsylvania Uniform Construction Code, replacing windows in their existing openings without changing the structure or the means of egress does not require a building permit. If the work enlarges or alters an opening, a permit is required. Either way, Norristown requires the contractor to be registered with the Municipality before work begins. We handle that registration, any permit and inspections, and the paperwork, so you do not have to chase it.
My home is in one of Norristown's historic districts. Does that affect my windows?
It can. Norristown has local historic districts overseen by a Historical Architectural Review Board (HARB). Within those districts, an exterior change that needs a permit and is visible from a public street is reviewed for appropriateness, including window style, materials, and grille pattern. The HARB makes a recommendation and Municipal Council issues the Certificate of Appropriateness. We help confirm whether your property is in the district, choose windows that suit its historic character, and handle the HARB submission and approval.
My block is in a lower-lying area near the Schuylkill. Does humidity affect which windows I should choose?
It can. The riverside neighborhoods carry more moisture year round, which over time is hard on seals and hardware. During your consultation we factor that in when we recommend glass packages, frame materials, and installation details built to hold up in a humid, four-season climate.
Do new windows qualify for a federal energy efficiency tax credit?
Not for installations after 2025. The federal Energy Efficient Home Improvement Credit, known as Section 25C, expired on December 31, 2025 under the One Big Beautiful Bill Act, so windows installed on or after January 1, 2026 are no longer eligible for that federal credit. If your project was completed in 2025, ask a CPA about claiming it on that year’s return. The stronger, lasting savings come from lower monthly energy bills once drafty old windows are gone.
Is painting the interior trim included?
Products can be ordered factory-finished, and we handle all the capping and exterior trim work on your project. We do not paint interior trim. We replace your existing trim with primed trim, and you or a painter you hire finishes that primed trim once installation is complete.
How is my old window material 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 crews and disposed of in our own dumpsters at our warehouse.
