Why Thermally Broken Steel Windows and Doors Are Perfect for Storefronts

Have you ever wondered how much energy your storefront windows and doors are leaking? If your windows are outdated, you could be throwing money out the window—literally!

Thermally broken steel windows and doors might be your best bet to plug up that leak and keep your energy bills in check. Let’s dive into why Optimum’s thermally broken solutions are the ideal choice for businesses that experience heavy foot traffic and need large, eye-catching openings.

What Are Thermally Broken Windows and Doors?

Before we get into the benefits, let’s clarify what thermally broken steel windows and doors actually are. Simply put, these are systems designed to prevent heat transfer between the interior and exterior, thanks to an insulating barrier—called a “thermal break”—sandwiched between the steel frames.

Think of it like wearing a cozy jacket. The jacket creates a barrier between you and the chilly air outside. Similarly, thermally broken steel frames stop heat or cold from seeping in or out of your storefront. This not only keeps the interior more comfortable but also helps reduce energy consumption.

Why Should You Care?

Most storefronts are designed with wide, open spaces and large glass panes to showcase products. While this looks great, it also exposes you to higher energy costs if not managed properly.

Thermally broken steel frames create a solution where you can enjoy large windows and entrances without sacrificing energy efficiency.

The Benefits of Thermally Broken Steel for Storefronts

Now that we’ve got the basics down, let’s dive into the benefits. Here’s why Optimum’s thermally broken systems are perfect for your storefront:

1. Energy Efficiency Saves You Money

You’re in business to make money, not spend it on sky-high energy bills. Thermally broken windows and doors are designed with high insulating performance to help control indoor temperatures​​.

2. Keep Your Store Comfortable

A comfy customer is a happy customer! When the temperature inside your store remains consistent, people stay longer—and might even spend more. The thermal break technology prevents cold drafts in winter and traps cool air inside during summer. Essentially, you’re giving your customers an experience of consistent comfort year-round.

3. Durability That Outlasts the Competition

Steel is already known for its durability, but thermally broken steel frames take it a notch higher. You get the best of both worlds—sturdiness and energy performance. Plus, with galvanized cold-rolled steel in our systems, these frames last longer and resist corrosion​​​.

Look Good, Perform Better: Aesthetic & Performance Combined

And here’s the kicker: the durability of steel allows for grand openings and oversized windows that won’t warp or crack over time. Whether your store has vintage charm or a more contemporary edge, these windows blend seamlessly with any architectural style​​.
