Installing a commercial storefront window is a bigger job than many realize. It’s not just about replacing glass. It’s about structural integrity, energy efficiency, local codes, and long-term performance. We’ve done this work many times at RVW, and we know what goes into doing it right.
Whether you’re opening a new location or renovating an existing property, the process involves planning, preparation, and precision. That’s why understanding the full scope of storefront window installation is essential before you get started.
Planning for Performance and Appearance
When we begin any commercial window installation, we start with goals. Most business owners want curb appeal, which is understandable. However, energy efficiency and durability often come into play once we discuss long-term operating costs. Therefore, a good storefront window must strike the right balance.
We assess the building’s existing structure first. In some older commercial spaces, structural upgrades may be needed to support newer window systems. In other words, we need to make sure the bones can handle the weight and stress of modern materials.
We also look at sun exposure, shading, and wind direction. For instance, large windows on a south-facing wall might need glazing that limits solar gain. Similarly, areas prone to wind pressure need stronger frames and anchoring systems.
Preparing the Space for Installation
Once goals are defined, we prepare the site. This step includes removing any old frames, inspecting for damage, and checking the wall cavity. Often, we find rot or water damage that needs addressing before we can move forward. As a result, we always build time into our schedule for unforeseen repairs.
We also coordinate with building managers to minimize disruption. After all, many commercial properties operate while renovations are underway. That means clear signage, protective barriers, and working outside of peak business hours when possible.
Depending on the size and type of storefront, we may need to secure permits. In Calgary, for example, this includes meeting fire codes, egress standards, and energy compliance. For clients in older properties, this is especially important.

Choosing the Right Materials and Glass
Not all glass is created equal. In commercial storefronts, we often recommend tempered or laminated glass. These are not only stronger but also safer. In the event of breakage, they’re less likely to shatter into dangerous shards. Above all, safety is always a priority.
The type of frame matters too. Aluminum is the go-to choice for most storefronts because of its strength and low maintenance. However, we sometimes install composite or fiberglass frames where thermal performance is a concern.
Glass coatings are another consideration. Low-E coatings, for instance, reduce heat transfer and block harmful UV rays. Similarly, tinted or reflective glass can improve privacy while still allowing natural light inside.
In high-traffic areas, we may also suggest security films or bullet-resistant options. That is to say, material selection is tailored to the unique needs of each business.
Installation Day: What Happens Onsite
When installation day arrives, we bring all materials pre-measured and prepped for faster work. We begin by securing the space and protecting nearby surfaces. For example, we lay down floor protection and use temporary dust barriers to separate the work area from customers or staff.
Then we remove the old components, including any old caulking, fasteners, and trim. It’s essential that the opening is completely clean and dry before the new frame goes in. Otherwise, we risk compromising the seal.
After that, we insert the new frame, shim it into place, and secure it using fasteners that meet commercial code. Once level and plumb, we seal all edges using commercial-grade caulking and insulation foam.
The final step is installing the glass, whether as a single panel or part of a curtain wall system. We check for airtight seals, test for movement, and clean the window thoroughly. Most importantly, we inspect everything before wrapping up the job.
Managing Weather and Timeline Challenges
Weather is always a factor in Calgary installations. We plan for it, but we also stay flexible. Cold weather can affect how materials cure. Therefore, we monitor temperatures and may use heaters or temporary enclosures when necessary.
Likewise, wind and snow can create access issues, especially for second-story or multi-level storefronts. In those cases, we use scaffolding or lift equipment to ensure safety and precision.
Project timelines vary, but most storefront installations take one to three days. However, complex framing, customization, or unforeseen repairs may add time. That’s why we always provide a clear schedule and update it as needed.
For those dealing with larger renovations, it’s worth exploring windows replacement in Calgary to understand broader upgrade timelines and material choices.
Compliance, Inspections, and Follow-Up
Commercial storefronts must meet Alberta Building Code requirements. We stay current on these standards, especially regarding fire safety, glass types, and insulation values. Consequently, inspections are a regular part of our process.
We often coordinate with local inspectors to ensure compliance before finalizing a job. That way, there are no surprises after the work is complete.
After installation, we provide basic maintenance tips to help keep the new windows in great shape. For example, regularly inspecting caulking and cleaning with appropriate solutions can extend the life of the system.
When issues arise down the road, having documentation and a clear scope of work can simplify warranty claims or future upgrades. If you’re unsure where to begin or want to plan a project, feel free to Contact Us for support and guidance.
Tips Most Articles Skip
One tip many overlook is how window placement affects indoor lighting and product visibility. We always suggest walking through your space at different times of the day before choosing window dimensions. This helps identify glare spots or areas where additional shade or interior lighting may be needed.
Another under-discussed point is drainage. Even in sealed storefront systems, water must be managed. We often install weep holes, flashing, or exterior drip caps to redirect rain and meltwater. Without these elements, water can pool at the base and lead to long-term damage.
Noise control is another aspect worth considering. Busy streets, loading bays, or transit stops can create daily distractions. In those situations, thicker glazing or acoustic laminated glass can make a big difference.
Lastly, think about future access. If you plan on future signage or awnings, talk to your installer about where anchor points can be placed without affecting the integrity of the window.
