Commercial Door Materials and Temperature Changes

Your commercial entry door does more than open and close; it sets the tone for every visitor. Since it’s constantly exposed to the outdoors, your door must stand up to changes in temperature and humidity. When the weather shifts, materials expand, contract, or warp, which can lead to frustrating problems like sticking doors, gaps, or even lock failures.

That’s why choosing the right commercial door material for your building isn’t just about looks, it’s about long-term performance.

Commercial doors face a wide range of conditions throughout the year. Hot summers can cause materials to swell, while cold winters often make them shrink. Humidity can add even more stress, especially in regions with dramatic seasonal swings.

Some of the most common problems caused by temperature and weather changes include:

• Doors that stick or rub against the frame

• Gaps forming under or around the door

• Warping, swelling, or cracking

• Locks and hinges jamming due to expansion and contraction

• Condensation inside glass panels or on the frame

These issues don’t just make a door harder to use, they can also affect your building’s energy efficiency, security, and professional appearance.

Not all doors handle temperature changes the same way. Here’s a general look at how different materials respond:

• Steel Doors: Steel is strong and durable, but it expands in the heat and contracts in the cold. In freezing weather, moving parts like hinges and locks can stiffen if they’re not properly lubricated. On the other hand, in hot conditions, steel can become very warm to the touch and even uncomfortable for visitors.

• Wood Doors: Wood is naturally affected by moisture and temperature. In the summer, it can swell, warp, or absorb humidity, making the door harder to open and close. In the winter, the opposite happens; it contracts and can leave gaps that let in drafts. While wood has a classic look, it requires more upkeep to handle these seasonal changes.

• Storefront Doors: React to moisture and temperature changes, too. In hot months, the frame may expand slightly, and the glass can get very warm, which may cause seals or gaskets around the glass to loosen or degrade. In cold weather, the frame may contract, which can create small gaps around edges, allowing drafts or reducing thermal performance. While storefront doors offer a sleek, modern look and excellent visibility, they need proper seals and occasional maintenance (like checking weather-stripping or tightening hardware) to perform well year-round.

You can’t stop the weather, but you can take steps to minimize its impact on your commercial doors:

• Install Weatherstripping: Seals around the edges help block drafts, moisture, and gaps.

• Control Indoor Humidity: Using humidifiers or dehumidifiers keeps moisture levels balanced, preventing extreme expansion or contraction.

• Perform Regular Maintenance: Lubricating hinges, tightening hardware, and checking for peeling paint or rust keep doors operating smoothly.

• Choose Materials Wisely: Consider your local climate and business needs when selecting commercial doors. Some materials handle temperature swings better, while others are valued more for strength and security. The right choice depends on whether durability, energy efficiency, or appearance is your top priority.

The entrance to your business is a reflection of your brand. A door that sticks, squeaks, or looks weather-worn doesn’t send the right message to clients, employees, or visitors. By choosing the right material and keeping up with regular maintenance, you’ll extend the life of your doors and avoid costly replacements.
