Frequently Asked Questions

An IGU is a sealed unit made of two or more panes of glass separated by a spacer and filled with insulating gas (argon). It improves energy efficiency, reduces noise, and prevents heat loss.

Common signs include:

• Fog or condensation between panes
• Cracked or broken glass
• Drafts or poor insulation
• Cloudy or hazy appearance

If the frame is still in good condition, you likely only need the glass replaced—not the entire window.

Yes! We replace only the insulated glass unit while keeping your existing frame. This is more cost-effective and less invasive than full window replacement.

Fogging happens when the seal inside the IGU fails, allowing moisture to enter between the panes. Once this happens, the glass unit needs to be replaced.

Low-E (low emissivity) glass has a special coating that reflects heat while allowing light in. It helps keep your home warmer in winter and cooler in summer, improving energy efficiency.

Argon is a non-toxic, odorless gas placed between the panes of glass. It acts as an insulator, reducing heat transfer and improving overall window performance.

Yes. Replacing just the glass can save you significantly compared to full window replacement, especially if your frames are still in good condition.

Absolutely. New IGUs with Low-E coating and argon gas can reduce heat loss and help lower your heating and cooling costs.

Yes, we custom make glass units to match the size, thickness, and style of your current windows.

Yes, we offer a 10 year seal failure warranty.

Yes! We provide free, no-obligation estimates. You can send us photos and rough dimensions of your windows for a quick quote.
