Your Questions, Answered
Frequently Asked Questions
What are the most common types of windows offered by Thermo-Seal?
Thermo-Seal installs a wide range of types of windows, including double-hung, casement, sliding, bay, bow, awning, picture, garden, glider, and custom-shaped windows. Each style offers specific benefits in ventilation, operation, and design, and we’ll help you choose the right combination for your home.
Which window type is best for energy efficiency?
Casement windows and picture windows are among the most energy-efficient types of windows because they seal tightly when closed. Double-hung and sliding windows can also be energy-efficient when manufactured with advanced materials and installed properly—which is exactly what Thermo-Seal delivers.
Do different types of windows come in different materials?
Yes. Our types of windows are available in composite (like Fibrex® from Andersen), vinyl, fiberglass, wood, and even hybrid combinations. Each material offers a unique mix of durability, insulation, and maintenance level. We’ll help you compare options during your consultation.
Can I mix different types of windows in my home?
Absolutely. Many homes use a combination of types of windows—such as double-hung in bedrooms, a bay window in the living room, and awning windows in basements or bathrooms. Mixing styles allows for better function and aesthetic appeal tailored to each space.
Does Thermo-Seal install custom-shaped or specialty windows?
Yes, we do. In addition to standard window styles, we offer custom types of windows designed to fit unique openings, shapes, and architectural features. Whether you're restoring a historic property or customizing a modern design, we have the flexibility to match your vision.

Our Client Reviews
Aaron and his team were fantastic! Our windows were ready 2 weeks earlier than expected and his team was always on time. They were pleasant to have around, were respectful of our space and cleaned up after themselves. We had a problem with rot in one of our walls and Aaron and his team helped us to fix it as part of the window installation, including finding a great electrician at the last minute. Thanks, Thermo-Seal! We're very pleased.
Rachel R.
I had a very good experience with Thermo Seal. Chose them after interviewing many others bc they're local, communicated efficiently and offered good midrange pricing + lifetime warranty. Aaron was great to work on setting up the contract and and then Fabio and his crew did a fantastic job with the installation. They came early, they finished 5 windows in 4-5 hours, they cleaned up. Fabio even helped me take care of another issue he found on the roof. Highly recommended.
