a Trescher Brothers Inc company

Thermal Hero is the insulation division of Trescher Brothers, created to deliver high-performance spray foam and insulation solutions for Nantucket homes. We specialize in work that requires precision, planning, and an understanding of coastal construction.
From improving comfort in existing homes to insulating new builds, our focus is on clean execution, durable materials, and systems that perform in Nantucket’s demanding environment.
Our mission is to provide Nantucket homeowners and builders with insulation solutions that improve comfort, reduce energy loss, and stand up to coastal conditions. We believe insulation should be done correctly the first time — with attention to detail, proper material selection, and respect for the home.
Whether it’s spray foam, fiberglass, or rock wool, our goal is to build insulation systems that support the long-term performance and livability of each property.

The ultimate solution for energy efficiency, reducing heating and cooling costs while creating an airtight seal. Experience a more comfortable and eco-friendly home with our premium spray foam insulation.

Your key to superior soundproofing and fire resistance, providing peace of mind and safety for your home or business. Enjoy a quieter and more secure living or working environment with Rockwool's high-quality insulation solutions.

Offers a cost-effective and efficient way to keep your space comfortable year-round, while also being environmentally friendly. Experience significant energy savings and a more sustainable future with our reliable fiberglass insulation solutions.
Understanding the right R-value for your home is crucial for optimizing energy efficiency and comfort. It's not only about staying compliant with building codes but also about reducing your energy bills and creating a more comfortable living space. Take the time to find out what R-value suits your specific climate.
We understand the logistics, construction styles, and challenges unique to Nantucket projects — from access and scheduling to older framing and coastal exposure.
We use professional-grade spray foam systems designed for durability, efficiency, and long-term performance in demanding environments.
As finish carpenters and insulation specialists, we care about how work looks, performs, and integrates with the rest of the home.
Proper insulation means lower energy use, fewer drafts, and a more comfortable home — especially during Nantucket’s colder months.
