Round Top
Windows
Elegant arched design that adds timeless architectural distinction to any home. Also known as arch or half-round windows, they bring beauty and natural light to spaces above doors, standard windows, and gable ends.
What is a Round Top Window?
A round top window features a semicircular or arched top that creates an elegant silhouette unlike any standard rectangular window. Also called arch windows or half-round windows, they are most often fixed (non-opening) at the curved section, allowing for a seamless, unobstructed glass area.
Many round top designs include an operable lower section — typically a casement or single-hung sash — giving you the beauty of an arched profile with the convenience of ventilation when you need it.
Benefits of Round Top Windows
Round top windows combine dramatic visual impact with lasting performance, making them a standout upgrade for any home.
Elegant Arched Design
The graceful semicircular profile adds a level of sophistication that flat-top windows simply cannot achieve.
Architectural Distinction
Instantly elevates curb appeal and sets your home apart with a timeless design element found in the finest architecture.
Extra Natural Light
The arched glass area captures light from higher angles, flooding rooms with beautiful natural illumination throughout the day.
Pairs with Standard Windows
Designed to sit above rectangular windows and doors, creating stunning combinations without complex structural changes.
Curb Appeal
Round top windows are a focal point that draws the eye and adds perceived value from the moment someone sees your home.
Custom Sizing
Available in virtually any width and arch radius to fit existing openings or create new architectural statements.
Energy Efficient
Fixed arch sections provide an airtight seal with no moving parts, maximizing thermal performance and reducing energy loss.
Timeless Style
Popular in colonial, Mediterranean, and traditional architecture for centuries — a design that never goes out of fashion.
Premium Features We Include
Every round top window we install is built with advanced materials and engineering for lasting beauty and performance.
Low-E Glass
Microscopically thin metallic layers reflect infrared heat while admitting visible light, keeping your home comfortable year-round.
Argon Gas Fill
Inert argon gas between panes reduces heat transfer more effectively than air alone, improving thermal performance by up to 30%.
Custom Arch Radius
Each window is manufactured to your exact arch specifications — true half-circles, elliptical arches, or shallow curves to fit any opening.
Simulated Divided Lites
Achieve the look of traditional multi-pane glass with exterior grille bars and interior spacer bars — without sacrificing energy efficiency.
Premium Weatherstripping
Continuous fin-seal weatherstripping blocks drafts and moisture infiltration, ensuring a tight seal around the entire window perimeter.
Warm-Edge Spacers
Non-metallic spacer systems between panes reduce heat conduction at the glass edge and minimize interior condensation.
Where Round Top Windows Shine
Round top windows make the biggest impact in specific locations where their arched profile creates a dramatic focal point.
Above Entry Doors
Create a grand entryway with an arched transom that welcomes guests with elegance and natural light.
Formal Living Rooms
Add a statement piece that elevates the room's architectural character and draws the eye upward.
Above Standard Windows
Stack a round top above a rectangular window for a combined unit that looks custom and fills the wall with light.
Gable Ends
Fill the peak of a gable wall with an arched window that complements the roofline and adds interior light.
Master Bedrooms
Create a luxurious, spa-like atmosphere with an arched window that frames views and bathes the room in light.
Round Top vs. Standard Picture
Both are fixed windows designed for light and views, but their shape and impact differ significantly.
