Make your home beautiful with windows from ASAP Windows
What Are
Custom Windows?
Custom windows are made-to-order windows that go beyond standard sizes, shapes, and configurations. They’re designed to fit unique architectural openings, match specific design aesthetics, or solve functional challenges that off-the-shelf windows can’t address.
Whether you need a circular window for a turret, a trapezoid for a vaulted ceiling, or a combination unit that blends multiple styles, custom windows give you the freedom to create exactly what your space needs.
Features & Benefits of Our Custom Windows
Designed for Ventilation. Engineered for Alberta.
At ASAP Windows & Doors, our Custom Windows are more than just a stylish addition to your home—they’re a smart investment in comfort, energy efficiency, and long-term performance. Manufactured locally in Calgary, our awning windows are built to handle Alberta’s demanding climate while offering homeowners a sleek, functional, and secure solution for everyday living.
Whether you’re upgrading a bathroom, finishing a basement, or designing a new build, our awning windows are tailored to meet your needs with precision and care.
Your Vision. Our Craftsmanship.
Custom windows allow you to break free from standard templates and bring your architectural ideas to life. Whether you’re replicating a heritage detail or creating a modern focal point, we’ll help you design windows that are as functional as they are beautiful.
No Gaps. No Compromises.
Older homes and unique builds often have irregular openings. Our custom windows are built to your exact measurements, ensuring a seamless fit that improves energy efficiency and aesthetics.
Stand Out from the Street.
Custom shapes and configurations add visual interest and architectural character to your home’s exterior—boosting curb appeal and resale value.
Built for Alberta’s Climate.
Even with unique shapes and sizes, our custom windows are engineered for performance. With insulated frames, Low-E glass, and argon gas fills, they meet or exceed ENERGY STAR® standards.
Mix. Match. Combine.
Custom windows can be combined with other window styles—like casements, awnings, or picture windows—to create dramatic feature walls or functional combinations that suit your space.
Built to Last.
Our custom windows are made with the same high-performance materials and craftsmanship as our standard lines—ensuring long-term durability, weather resistance, and low maintenance.
Our casement windows are:
- ENERGY STAR® Certified
- NAFS-11 Tested
- CSA A440 Compliant
These certifications ensure your windows meet or exceed Canadian standards for air, water, and structural performance—giving you peace of mind and long-term value.
Where to Use Custom Windows
Custom windows are incredibly versatile and can be installed in nearly any room of the house. Their compact design and weather-resistant functionality make them ideal for:
Bathroom
For privacy, moisture control, and fresh air.
Kitchens
Above countertops or sinks where space is limited.
Basements
As a secure, weather-resistant option for non-egress openings.
Bedrooms
Paired with fixed windows for added ventilation and style.
Living Areas
Combined with picture windows for panoramic views and airflow.
They’re also a great choice for multi-window configurations, such as stacked or side-by-side installations.

- Airtight Seals – Prevent drafts and moisture infiltration.
- Insulated Frames – Reduce heat loss and improve energy efficiency.
