What is a Thermal Break?

A thermal break is a barrier that is placed between the inner and outer frame of a door. It is made of a material that does not conduct heat well, such as fiberglass, resin, or other composite materials.

The purpose of a thermal break is to prevent heat from transferring from the inside to the outside of the home, or vice versa. This can help to improve the energy efficiency of your home and save you money on your heating and cooling bills.

How Does a Thermal Break Work?

When heat passes through a material, it is transferred from one molecule to another. The faster the molecules move, the hotter the material is.

Materials that conduct heat well, such as metal, have molecules that move quickly. Materials that do not conduct heat well, such as fiberglass, have molecules that move slowly.

A thermal break works by interrupting the flow of heat through a door. Placed inside the frame of the door, the barrier serves to prevent heat and cold from easily transferring from outside your home to inside, and visa versa.

Benefits of Thermal Breaks

There are several benefits to having a thermal break on your doors and windows. These include:

  • Improved energy efficiency: Thermal breaks can help to improve the energy efficiency of your home by preventing heat from transferring from the inside to the outside, or visa versa. This can save you money on your heating and cooling bills.
  • Reduced condensation: Thermal breaks can help to reduce condensation doors. Condensation occurs when warm, humid air meets a cold surface. The thermal break creates a barrier that prevents the warm air from reaching the cold surface, which can help to reduce condensation. This can, over time, prevent water damage inside your home at the door’s threshold.
  • Increased durability: Thermal breaks can help to increase the durability of your doors. They can protect the frames from the elements and prevent them from warping or cracking.
  • Added security: Thermal breaks can help to increase the security of your home. They can make it more difficult for burglars to break into your home through a door.

Thermal Break Door Installation

A thermal break is a valuable addition to your front door in many climates. It can help to improve the energy efficiency of your home, reduce condensation, increase durability, and increase security.
