Casement windows are one of the most practical and efficient window styles you can install. They open outward to a full 90° with an easy crank handle — perfect for catching a breeze, directing airflow, and cleaning from inside the house.
When you close a casement window, two rubber tube seals compress — just like a car door gasket — which makes it far more airtight than a sliding or hung window. That means better insulation, less noise, and no cold drafts sneaking in on windy days.
All the windows in my own home are casements. No sliders, no double-hungs — and I’ve never regretted it.

Why Casement Windows Are Worth It
Casement windows combine efficiency, airflow, and simplicity better than almost any other window type.
Superior insulation – Two compression seals and a solid locking mechanism keep air leaks to a minimum.
Great ventilation – Opens a full 90° outward, catching side breezes and venting warm air fast.
Easy cleaning – Hinged design lets you clean both sides from indoors.
Durable hardware – Smooth crank operation and multi-point locks for long-term reliability.
Energy efficiency – Perfect for modern Low-E or triple-pane glass packages.
The only real drawback? You can’t fit a window A/C unit into a casement — but for comfort, airflow, and performance, that’s a fair trade-off.
Our casement windows are made from an exclusive 100% lead-free uPVC compound.
It resists impact, fading, blistering, and warping — keeping your windows maintenance-free for decades. The color stays consistent inside and out, and the frames never need painting.
Casement Window Installation Options
Installation plays a huge role in how well your windows perform and how long they last.
Installation Type
Description
Best For / Benefits
Brick-to-Brick (Recommended)
Full removal of the old window up to the house framing. Includes options for three brickmould accessory sizes and upgrades to interior trim and jamb.
Highest efficiency and insulation upgrade. Ideal for replacing damaged or poorly insulated windows.
Retrofit Installation
The existing frame and trim remain intact. Only the sash and glazing are replaced, making the process faster and less expensive.
Great when the current frame is solid and well-insulated. Allows for glazing upgrades without major renovation.
Stud-to-Stud Installation
Complete removal down to the house framing. The exterior is finished with caulking or aluminum flashing.
Similar efficiency boost to brick-to-brick. Perfect for rotted, outdated, or poorly insulated frames.
Casement Window Glass and Glazing Options
Choose between double and triple glazing for your preferred energy performance. Pair that with one of our Low-E coatings to fine-tune comfort and savings:
LoE 180 – High solar gain for colder climates.
LoE2 272 – Balanced performance for year-round comfort.
LoE3 366 – Maximum UV and heat protection.
LoE i89 – Added interior insulation for extreme efficiency.
Clear Glass – Bright, simple, and great for noise reduction.
Triple Glass – Three panes for the best insulation possible.
Super Spacer for Casement Windows
Every casement window we install uses Super Spacer warm-edge technology, a dual-seal insulating glass system with no metal. It keeps the glass edge warm and dry, reduces condensation, and improves overall energy performance.
Why it matters:
Prevents condensation and mold
Boosts R-value and insulation
Extends window lifespan
Keeps indoor temperatures consistent year-round
Metal-based spacers can lose up to 50% of a window’s rated R-value — which is why we never use them.
Trim, Jamb, and Brickmould Options for Casement Windows
Our vinyl casement windows can be finished to match any interior or exterior style.
Interior trim styles – from contemporary flat trims to classic rosettes
Four standard jamb sizes – with wood jamb extensions available
Durable uPVC brickmoulds – maintenance-free, in multiple sizes and colors
Everything is built from the same high-grade PVC compound for color consistency and durability.
Energy Efficiency and Comfort
Between double or triple glazing, compression seals, and Super Spacer technology, our casement windows are among the most efficient on the market. They keep the heat where you want it, reduce condensation, and help lower energy bills all year round.
A properly installed casement window doesn’t just save energy — it adds real comfort you can feel.
From personal experience, casement windows are the most airtight design you can install.
They hold up against high wind gusts without a whisper of a leak. Once you’ve lived with that kind of performance, it’s hard to go back to sliders or hungs.
If you’re planning a window replacement and want real energy efficiency that lasts, start with casement windows — they’re built to seal, last, and perform.
