Residential Windows
We install energy-efficient double-hung, casement, and tilt-and-turn windows for homes. Our products enhance insulation, reduce noise, and improve curb appeal while offering easy maintenance features like inward tilting sashes. Custom options ensure seamless integration with traditional or modern architectural styles.
Commercial Windows
Our commercial window solutions meet strict building codes for high-rises, factories, and institutions. We handle complex installations using aluminum, fiberglass, or reinforced vinyl materials. Services include fire-rated windows, large-scale replacements, and specialized equipment operations for hard-to-reach areas.

Riot Glass provides bullet-resistant protection for storefronts and high-risk commercial properties. This transparent security system withstands forced entry attempts while maintaining visibility. Ideal for banks, retail locations, and facilities requiring enhanced safety without compromising natural lighting.

Custom storm doors add an extra insulation layer to entryways, reducing energy costs and protecting primary doors from weather damage. Our durable, low-maintenance options feature adjustable ventilation and modern designs that complement various home exteriors.
Patio Doors
We install energy-efficient sliding and French patio doors that create seamless indoor-outdoor transitions.

We were very pleased with the service. The installation went quickly and smoothly, the workers were very competent and thorough and they respected our wishes. Communication with both them and the office was always prompt and courteous. We are pleased with the product and look forward to years of use.

Ordered a screen door and exterior entry door March 31st. We were told 8-10 weeks before installation. Twice the person who did the scheduling " was on vacation". It's 15 weeks later and no doors. We had new siding, soffit and gutters installed by one their competitors within a month. No communication and a bunch of BS from American Thermal. DO NOT GO WITH THIS COMPANY. Next step is to file with Business Affairs and Consumer Protection with the city

I recently had my Florida Room Windows replaced with American Thermal Windows. I was desperate after the first company that we hired to do this project dropped us like a hot potato after seeing the scope of the project. I called A.T.W. and made an appointment not knowing what to expect. Colleen arranged to come the following morning. She made me… feel at ease almost immediately! She guaranteed that the project was going to be done without any problems. A few minutes after she had arrived, Iver, the owner of the Company showed up and assured us that the project was feasible.

We bought a front door from American Thermal last year and we’re so happy with the door we decided this year to order a patio door and a screen door for the front. Nick is awesome and the installers were awesome! I will continue to recommend this company!

Stanley and Jerry door installers did an awesome job. Even the City inspector said he has never seen such a detailed job like this. I love these doors. Very professional. Also all the customer service (Dee & Ruby) were so helpful and get things done.

We purchased a security storm door for our front door through American Thermal Window. We had Vitaly & Dema install the door, and they were very professional and quick. Our storm door looks beautiful, and we had a great experience with them. I highly recommend American Thermal Window for anyone who is looking for new windows or storm doors!
