J. C. Tonnotti recommends and installs Therma-Tru entry doors for some pretty impressive reasons. Therma-Tru fiberglass entry doors were the first fiberglass door on the market. There were revolutionary because they “looked as beautiful as wood but performed with the durability of steel”.


Therma-Tru entry door systems are unrivaled in the industry. They will increase your curb appeal, provide energy efficiency, and they provide performance. In fact the benefits of installing a Therma-Tru entry door are:


Advantages

Curb Appeal, Energy Efficiency, and Security


Curb Appeal Improvement

The installation of an attractive new front entryway is “the” most cost-effective investment that can have a HUGE impact on your curb appeal.


There are quite a few different Therma-Tru entry door designs to pick from. Our door installers will help you select and configure your entry door and identify the required door height, door style, and glass styles.


If you are looking to sell your home, the Therma-Tru name is known and appreciated by home buyers. This is because prospective buyers are looking for quality and performance as well as beauty.


A Therma-Tru door means you are making a commitment to add style and curb appeal to your home. And more than ever before, Connecticut homeowners are looking to get the most out of every dollar they spend on their home.


Energy Star Rating

A door that achieves an energy star rating must insulate well and provide a complete seal.


  • Fiberglass doors insulate up to five times better than wood doors.
  • The R-value of a material measures its insulating properties.
  • Fiberglass doors from Therma-Tru are installed with a polyurethane foam core (R-5.5 to R-6.5 per inch), which insulates much better than hardwood (R-0.71 per inch).
  • Another advantage of fiberglass is that it does not conduct heat, which minimizes the exchange of heat between the two sides of the door, and in the winter, your door will be warm to the touch.


Security Upgrade

Therma-Tru doors can be upgraded with the Tru-Defense Door System to maximize the seals to keep out the damaging effects of wind, snow, and rain. This also further increases the door’s energy efficiency.


Homeowners will have peace of mind with a Therma-Tru fiberglass entryway and the Tru-Defense Door System – it is is backed by a full system warranty rider.
