Commercial Wood Door

When it comes to commercial doors, safety isn’t just a suggestion, it’s the law. But do all doors really need crash bars? From bustling retail spaces to quiet offices, understanding when and why crash bars are required can save lives and keep your business compliant. 

A crash bar is a type of door hardware designed to allow quick and easy exit from a building during an emergency. It is usually installed on the inside of commercial or public doors and operated from the inside of an outswing exit door through the use of a crossbar or push rail. It works by simply pushing on a horizontal bar to unlatch the door, enabling people to exit swiftly without turning a knob or using a key. The concept is that only minimal pressure is needed to disengage the latch, and importantly, no twisting or gripping is required.

Not every commercial door is created equal, and the regulations reflect that. Authorities establish criteria for when crash bars are mandatory, which

When you stroll through a building, you rarely pause to think about the doors you pass. But with each door swing, you are either passing an interior or exterior door. Both types of doors are made differently because they serve two distinct purposes. 

Exterior doors act as guardians, shielding your home from the outside, while interior doors carve your living space into distinct rooms. At first glance, the difference seems straightforward, but it isn’t, and they vary in design, materials, and functionality. In this article, we’ll unpack the purpose of interior and exterior doors, explore hybrid or mixed applications, and help you pick the right door for your space.

Interior and exterior doors both serve the same fundamental purpose of opening and closing, but the way they are built, designed, and equipped varies greatly. To better understand these distinctions, let’s break down the key differences between interior and exterior doors.

While it's always been important, the call for classroom door security is more urgent today than ever before. Active shooter situations were once rare. In 2025, they are common. The right classroom door can provide an added layer of security in the event of an emergency.

Which is the best choice for a breach-resistant door? Steel is obviously the strongest. However, it may be out of the price range if you're outfitting an entire school.

If you’ve ever walked into a room and felt a sudden chill around your ankles, you know the problem: the dreaded under-door draft. It seems small, just a sliver of space under the door, but it adds up. Cold air slips in, warm air leaks out, and before long, you’re dealing with higher bills and uncomfortable tenants.

So let’s talk about why drafts happen, how you can spot them, and the real-world fixes that actually work.

Think about it like this: even a gap as small as one-eighth of an inch around a door can let through as much air as a window that’s half open. That’s not just a nuisance; it’s wasted money. According to the U.S. Department of Energy, uncontrolled air leaks in commercial buildings account for nearly one-third of heating and cooling loss every year.

And when you look at the big picture, the costs are serious. The Energy Information Administration estimated that commercial buildings spent $142 billion on energy in a single year, with insulation/energy

Choosing the right commercial door is not just a design decision. The type of door you install affects safety, compliance, and how people experience your building. If you're a contractor, facility manager, or business owner, you've probably asked yourself which door is best for a particular space. The answer depends on where the door is going, how it will be used, and what regulations apply.

Steel doors are one of the most common choices in commercial projects. You'll see them in stairwells, back entries, corridors, and anywhere security is a concern. They are durable, withstand heavy use, and can be ordered with fire ratings to meet building codes.

A commercial steel door can also be customized with glass kits or louvers, so you're not limited to a blank panel. The Steel Door Institute's ANSI/SDI A250.8 standard sets out how these doors should be built and tested, which is why they're a reliable option when you want proven performance.
