What Are the 4 Main Types of Windows?

Windows do more than let in light. They shape the look of your home, affect how it feels inside, and play a big role in your energy bills. Choosing the right window type isn’t just a design decision – it’s a functional one.

The windows you pick can impact how much heat you keep in during winter, how well your home stays cool in summer, and even how much noise you block from the outside. They also influence your home’s resale value and curb appeal.

At American Quality Remodeling, we’ve helped homeowners across New Jersey upgrade their homes with smarter, better-performing windows. Whether you’re renovating or building new, we guide you through the options and help you choose what works for your home – not just what looks good in a catalog.

In this guide, we’ll answer the common question: what are the 4 main types of windows that homeowners should consider?

Which Window Type Is Right for Your Home?

There are dozens of window styles out there, but most fall into four main categories: single-hung and double-hung, casement and awning, sliding, and fixed or specialty windows. These types are based on how the window operates, how much airflow it allows, and where it works best in the home.

Understanding these categories makes the window selection process much easier. At American Quality Remodeling, we help you determine which type fits your space, budget, and style – and how to mix and match where needed.

Let’s break down each one.

Type 1: Single-Hung and Double-Hung Windows

Single-hung windows are a classic. The bottom sash moves up to open while the top part stays fixed. They’re simple, budget-friendly, and work well in most traditional-style homes. These windows are easy to install and maintain, making them a go-to for homeowners looking for clean, reliable functions without overcomplicating things.

That said, cleaning the exterior of the top sash can be tricky unless you can reach it from the outside. And because only one part opens, airflow is limited compared to other styles.

Double-hung windows solve some of those issues. The top and bottom sashes move, allowing better ventilation and easier cleaning. Many models tilt inward so you can clean the glass from inside your home – a major plus during cold New Jersey winters.

These windows are great for bedrooms, living rooms, and anywhere you want airflow and function. They also help balance humidity and air movement, which is important in NJ’s mixed climate.

In terms of cost, bi-fold windows tend to be a bit more expensive than single-pane windows, but they are much more convenient and functional. Both types of windows are available in vinyl, wood, fiberglass, and composite materials, each with their own benefits and price points.

Type 2: Casement and Awning Windows

Casement windows open outward using a crank. They’re hinged on one side, opening like a door. This design allows for excellent ventilation and tight sealing when closed, making them one of the most energy-efficient types on the market.

Because the entire window opens, you get more airflow than with double-hung or sliding options. They also lock securely and seal tightly, helping reduce drafts in winter. That’s especially helpful in exposed areas or near the shore, where wind and cold can be an issue.

Casement windows come in a range of styles – from modern narrow frames to more traditional grille patterns – and can be used solo or in pairs.

Awning windows are similar but hinged at the top and open outward from the bottom. They’re perfect for letting in air while keeping out rain. That makes them ideal for bathrooms, basements, and even over kitchen sinks.

Awning windows are often used in combination with larger fixed windows to create visual interest and boost ventilation. They also pair well with modern architectural styles.

Both casement and awning windows offer strong insulation and sealing performance. They’re available in various materials, including fiberglass and vinyl, and can be fitted with secure locking hardware for added peace of mind.

Type 3: Sliding Windows

Sliding windows move horizontally along a track. One panel slides over the other, making them a great space-saving option – especially in rooms where a window that swings outward or inward might get in the way.

They work well in tight areas like above a kitchen sink or along patios, decks, and walkways. Because they don’t require clearance to open, they’re a smart fit for homes with limited exterior space.

Sliding windows are easy to operate and low-maintenance. Fewer moving parts mean fewer things can go wrong. Many models come with removable sashes, which makes cleaning the glass much simpler than you’d expect.

Pocket sliding windows are a more custom option. They allow one or more panels to slide into a wall pocket, creating a large open space with minimal visual obstruction – perfect for modern homes or those with beautiful backyard views.

Sliding windows can be as energy-efficient as other types when properly sealed and fitted with double or triple glazing. In New Jersey’s climate, this matters. Our team at American Quality Remodeling always recommends the right glass and frame materials to keep your heating and cooling costs down.

They’re often more affordable than casement or double-hung windows, making them a good choice for homeowners who want clean lines, good function, and solid performance without overspending.

Type 4: Fixed and Specialty Windows

Fixed windows don’t open, but they serve a big purpose: letting in natural light and offering a clear, unobstructed view. These include picture windows, which are large, clean-framed panes often used in living rooms, staircases, or anywhere you want to bring the outdoors in.

Because they’re sealed completely, fixed windows are incredibly energy-efficient. There’s no risk of air leaks, and their simple design means less maintenance over time.

We often pair picture windows with operable styles like casement or awning windows nearby, so you get both light and airflow.

Then, there are bay and bow windows – larger setups extending from the wall to create a small shelf or seating area inside. These not only bring in more light but also make rooms feel bigger. They’re great for traditional homes throughout New Jersey and can even boost property value.

Architectural windows go further. Think round, hexagonal, triangular, or custom shapes. They are used to create a design statement or preserve the character of older homes. They’re often seen in historic districts or homes undergoing restoration work.

Whether you’re going for classic charm or modern impact, specialty windows allow for more creativity and personalization. Remember that unique shapes may require custom glass and framing, which can affect pricing and timelines.

Beyond the Basics – Window Materials Matter

Style is one thing, but material matters just as much – especially with New Jersey’s hot summers, cold winters, and everything in between.

Vinyl windows are popular for a reason. They’re energy-efficient, low-maintenance, and cost-effective. Vinyl doesn’t rot or peel; modern versions come in plenty of colors and finishes. For homeowners on a budget who want solid performance, vinyl is usually the go-to.

Wood windows offer timeless beauty and natural insulation, but they require upkeep. They need to be sealed or painted regularly to avoid moisture damage. They’re a great fit for older or historic homes where maintaining authenticity is a priority.

Fiberglass windows are strong and weather-resistant, perfect for New Jersey’s changing seasons. They don’t expand and contract like other materials, so they hold their shape and seal better over time. They’re a bit more expensive, but the long-term durability often makes up for it.

Aluminum windows are sleek, modern, and structurally strong – but not always the most efficient unless they’re thermally broken (insulated). We recommend them for specific modern designs or commercial applications where appearance and strength matter more than insulation.

Successful Window Transformations

Colonial Home in Princeton, NJ

This homeowner had outdated wood windows that were drafty and hard to open. We replaced them with double-hung vinyl windows with Low-E glass. The result is improved insulation and a stylish addition to the room’s design. The family reported lower heating costs that winter and noticed the home stayed cooler in the summer.

Style and Function – Historic Home in Montclair

Preserving the look of this early 1900s home was a priority. We installed custom wood-clad specialty windows with matching grille patterns.

The homeowner said neighbors and passersby noticed the change right away – and so did their energy bills.
