The Benefits of Upgrading to Modern Curtain Wall and Storefront Systems

Older curtain wall and storefront systems weren’t built for today’s energy codes, weather conditions or performance expectations. In Pennsylvania and across the Mid-Atlantic, buildings face freeze-thaw cycles, heavy rain, humidity, high winds, and rising energy costs — all of which put stress on aging systems.

A modern curtain wall or storefront upgrade can improve energy efficiency, enhance curb appeal, increase durability and reduce long-term maintenance costs.

At UPG, we’ve been installing modern systems for decades. We understand the region, the buildings, and the importance of clear communication and coordination throughout the entire process.

What Are Curtain Wall and Storefront Systems?

Curtain walls are non-structural exterior glazing systems — typically floor-to-ceiling glass that encloses a building’s exterior while allowing natural light and modern aesthetics.

Storefront systems are ground-level commercial entrance and window systems, commonly used for retail spaces, offices and multi-level commercial buildings.

How do I know it’s time to replace my curtain wall?

The biggest sign that it’s time to replace your curtain wall is if you notice water damage or leaks. You might also notice bowing or cracks in the system or other glass issues. A typical glass curtain wall (with the right care) lasts about 25-40 years, so even without the warning signs, if your wall is getting into that age range, it’s vital to think about a replacement.

How do I know it’s time to replace my storefront system?

Water damage and leaks is a huge indicator of problems with your storefront system. You might also notice cracking or shattering, foggy panes, rusted or rotted frames, difficulty in opening and closing doors and higher energy bills.

A typical storefront system lasts around 15-30 years, based on the maintenance and history of the building. 

What are the benefits of upgrading to a modern storefront system? 

  • Cost Savings

If your heating system can stop working overtime to make up for out-of-date and damaged systems, your energy bills will see a significant drop. 

  • Energy Efficiency

Modern systems offer:

  • Advanced thermal breaks. These are engineered components integrated into aluminum or steel frames to reduce the heat transfer between interior and exterior environments.
  • Low-E (low-emissivity) coatings. These are tiny, transparent, metallic oxide layers applied to glass surfaces that aid in energy efficiency.
  • Insulated glass units (IGUs). These are sealed, double- or triple-pane glass units. They are separated by an insulating air or gas-filled spacer. They minimize heat transfer, reduce noise and prevent condensation. 

There could be potential utility rebates or tax incentives for energy-efficient upgrades, so discuss with your accountant. 

  • Safety

With a new system in place, you can ensure you stay up to code for your property and for insurance purposes. Glazing options can make for a strong system that resists impact and by adding locking mechanisms and reinforced frames, you keep unwanted visitors out and your team safe. 

  • Curb Appeal 

Custom options like tinted glass or frame designs can help you stand out and your customers get the first impression you want them to have. No more outdated, weathered entrances. Your business looks welcoming and well-maintained.

  • Natural Light

Natural daylight coming into your storefront is beautiful, but not when it causes a glare. A new system eliminates that worry and studies actually show that natural light can boost sales and productivity. 

  • Weather Resistance

We deal with a variety of weather factors in PA and the Mid-Atlantic, from freeze-thaw cycles to high winds to damaging rain and sticky humidity. With better seals, water cannot penetrate your systems as easily and maintenance costs are lower.
