So let’s get started on this journey to explore the many facets of bay windows, with Rosenow Customs guiding the way.
What Exactly is a Bay Window?
A bay window refers to a window space that protrudes outward from a home’s wall and forms a bay or alcove in a room. Typically, a bay window consists of three separate windows:
A large, main center picture window
Two flanking windows at 30° or 45° angles on either side
This angled shape gives bay windows their signature polygonal “bow” look from interior and exterior views.
Structurally, bay windows have foundations extended underneath the bay which bear the weight. This allows them to “float” out from the house without external bracing or supports. The windows in the three segments can open and close like normal windows as well.
Now compare this to a bow window, which has four or more continuous windows in an arched shape. While both project outward, bay windows have distinct angles compared to the smooth curve of a bow.
Purpose and Benefits
So why add bay windows to a home? What purpose do they serve beyond looking interesting? Well, there are many great benefits bay windows provide:
Increased space – The extended foundation literally increases the square footage and sense of usable area in a room. It’s almost like an addition!
Enhanced lighting – With glass on three sides and no vertical obstructions, bay windows flood rooms with beautiful natural illumination. Rooms feel bright, open and inviting.
Better views – The window’s protrusion enables more expansive exterior views that would otherwise be cut off from a flat wall. Enjoy extra visibility of gardens, landscapes or other sights from inside.
Ventilation – Casement windows integrated on the angled sides provide excellent air flow when opened, allowing fresh air circulation.
Flexibility – The extra floor space created can serve all kinds of functions based on needs. More on design ideas later!
Ultimately bay windows create tangible, functional improvements to living spaces beyond just looking architecturally interesting on the exterior. They seem to almost bring the outside in through light and views.
Styles and Placement
There are a few key variables that impact the style and placement of bay windows:
Angles
Bay windows typically protrude at angles of 30 or 45 degrees. The sharper 45 degree angle enables more glass surface area exposure.
Materials
Wood – Classic material with custom staining/painting that fits traditional home styles well
Vinyl – Affordable, low maintenance, energy efficient
Aluminum – Sleek and contemporary metal frames to match modern exteriors
Fiberglass – Glass-reinforced frames that are durable and dent-resistant
Location
Some common locations for bay windows since they allow more light and views:
Living Rooms
Kitchens, above sinks or as breakfast nooks
Bathrooms to amplify natural light
Stairwells and landings
Entryways for curb appeal
History and Popularity Over Time
The exact origins of the classic angled bay window form are unclear, but most sources cite early English architecture, potentially as far back as the late Medieval period.
However, bay windows and closely related bow windows became especially prevalent in the United States and England during the Victorian era (1837-1901). Improved glass making, framing techniques and engineering enabled more elaborate bay window construction. Their elegance and expanded views aligned well with Victorian preferences toward ornamentation and ostentatious grandeur.
You can see splendid examples of decorative Victorian bay windows in the famous Painted Ladies homes of San Francisco.
Popularity for bay windows continued through the early 20th century as well. For example, the American Foursquare houses built between 1900-1920 often incorporated one or more large bay windows.
These trends carried bay windows solidly through over a century of architectural relevance. And thanks to their classic charm and enduring functionality, bay windows maintain strong popularity in homes today.
Modern builds now integrate more energy efficient glass panes and sustainable materials into bay window construction. Home owners also utilize bay windows more creatively than as solely decorative features.
Installation, Construction and Engineering
If you’re considering adding new bay windows or replacing existing ones in your home, what should you know about the process?
We’ll cover key steps for installation along with structural considerations.
Stages of Bay Window Construction
Installing quality bay windows takes careful planning and coordination. It’s definitely not a DIY project for amateurs either. Work with experienced contractors for the best results.
Here is the basic construction sequence:
Pre-Installation Inspection
Assess current wall structure
Engineer custom dimensions
Framing
Extend foundation
Build interior seats
Construct support ribs
Window Integration
anchors, sealants
seam waterproofing
Exterior Integration
siding, roofing, flashing
trim moulding attachments
Interior Finishing
Insulate cavities
Add support brackets
Install chosen window dressings
And voila – your custom designed bay window!
Structural Considerations
Integrating a bay window is not as simple as knocking a hole in your wall. Professional assessment of a home’s structure is needed, along with planning for:
Foundations – shallower brick/block supports must be extended under the bay
Roofing – the roof line will be impacted and needs reshaping
Insulation – walls and cavities will need proper insulating foams/batts
Flashing – protects the intersection of window and wall from leaks
Consult a reputable contractor early on to evaluate feasibility and costs for your property.
It’s simpler to install bay windows in spaces bordering the home’s exterior rather than tearing into inner walls. Corner locations are also preferable for structural stability and flexible foundation access.
Buying Bay Windows
Once plans come together for size, placement and budget – it’s time to purchase actual windows!
Bay windows aren’t carried as ready-made stock. Instead they are custom assembled from individual window units, usually as combinations of:
Picture windows – Fixed panes in the central position. Available double-paned.
Double hung windows – openable upper and lower sashes
Casements – side hinged panels that crank outward
Window manufacturers like JELD-WEN, Pella and Andersen build both wood and vinyl bay windows to order. Customization options for glass patterns, grids, hardwares and more help them fit aesthetic needs.
Be sure to buy windows promoting energy efficient glass coatings and argon/krypton gas filling between panes. This boosts insulation while aligning with modern standards. Safety laminations also provide protection during storms.
Costs and ROI
Custom bay window installation is not cheap. Total costs typically range from $5,000 to well over $10,000 depending many factors:
Type/quality of windows
Structural complexity
Window size
Custom moldings and finishes
Construction labor rates in your area
However, the return on investment can make the upgrade worthwhile through:
Increased home resale value
Lower energy bills
More functional living spaces
Greater natural light benefits
Energy Efficient Models
Gas filled panes with improved insulation
Available certification by the National Fenestration Rating Council – means independently verified energy performance
Consider bay windows as long-term investments enhancing occupant comfort and quality of life indoors.
Design Ideas and Usage
A common question folks have when seeing bay windows is, “that nook looks cool, but what do you DO with the space?”
Well quite a lot, actually! Bay windows present fun opportunities to create specialized zones within your rooms. With a little creativity, the possibilities are endless.
Create customized spaces
Take advantage of the bay’s “free space” to carve out useful niches:
Reading nooks – perfect for getting cozy with a book
Window seats – cushioned benches lining the bay for extra seating
Plant displays – the light and space are ideal for potted greenery
Shelves or cubbies – use the bay as storage for items on open or closed shelves
Cat beds – our feline friends love to curl up and watch the views
Play areas – use bay floors as creative room for kids
You’re really only limited by floor space dimensions and ceiling heights above. Measure carefully when conceptualizing your bay additions.
Match Style with Your Home’s Architecture
Beyond function, incorporating a bay window enables very attractive exterior façades. The protruding shape can complement multiple home archetypes:
Victorian – Ornate angles with lavish filigree pair beautifully with Victorian Gothic motifs
Farmhouse – Rustic wood materials and simple lines for a pleasant country feel
Contemporary – Sleek metallic framing flows with modern minimalist designs
Mediterranean – Arched windows and tile or stone integrate nicely
Colonial Revival – Brick cladding with formal symmetry states historical elegance
Take cues from the existing building when choosing finishes. Then have fun flexing design creativity for the bay’s interior dwellings.
Plants, Seating and Beyond
Some more specific bay window dressing ideas to spark inspiration:
Frame views with backless bookshelves for displaying framed photos, vases or sculptural accents. Allows light through windows.
Include movable ottomans or small tables bringing versatile furniture arrangements
Layer window panels and valances to soften angles
Incorporate built-in bench seating with flip-top storage underneath
Rotate seasonal decor like flowering plants or holiday figurines to keep views fresh
Take measurements to estimate what pieces can reasonably fit. Be creative mixing materials like woods, woven textures and metallics for eclectic charm.
Comparisons to Other Windows
How do bay windows compare functionally to other window types? Let’s contrast benefits.
Comparison Bay Window Regular Window
Natural Light Maximum light from 3 sides Standard single direction
Ventilation Angled windows encourage cross breeze Limited based on opening style
Exterior Views Expansive, protruding perspective Restricted by flat wall
Interior Space Extends useable square footage Flat against wall
Installation Challenging foundation work Straightforward framing
Energy Efficiency Advanced glazings counter heat loss Similar glass available
Costs$5k – $15k+, custom build$100 – $500, off-the-shelf
There are certainly trade-offs of challenges vs. rewards when evaluating adding bay windows. Assess how improved aesthetics, comfort and resale value balance against upfront pricing.
