Craftsman Entryway Iron Door - 40" x 96" Eyebrow LH Inswing
HOW TO MEASURE YOUR DOOR SIZE
Our door sizes are measured from outside of jamb to the outside of the jamb. For example, a 36” x 96” door listed on our website means that 36” is the width from outside to outside of jamb (not the actual width size of the door) and 96” is the height from outside of jamb to bottom of our built in steel threshold (not the actual height of the door).
WHAT IS IT?
A thermal barrier that is highly resistant to thermal conductivity. This
significantly lowers the U-value and reduces HVAC costs in areas with hot or cold weather. A thermal break is used to reduce the flow of heat and cold through the metal unit in either the jamb or the whole unit.
To further explain how this thermal break technology works, well first explain why doors and/or other home materials without thermal breaks are not
optimal to maintaining temperatures in a home. There are inefficient things within your home called "thermal bridges" that are more conductive (or poorly
insulating) material. Materials like wood, metal, and concrete allow an easy pathway for cold or heat flow across a barrier. This results in conducting far more cold or heat than the insulation on either side of them.
In essence, a thermal bridge causes energy to be lost easily through material with little thermal resistance, impacting continuous insulation. This ultimately
affects the sale-ability and more importantly, home comfort. This is because the goal of homeowners is to combat the outside elements of frigid cold, and hot
summer months from affecting the desired temperature on the interior of the home.
This is where the importance of thermal break technology comes in. Now that you understand how thermal bridges can impact the overall efficiency of a home, you can now understand how thermal breaks help combat that problem.
Simply put, a thermal break is when a thermal bridge is purposefully broken. It creates a barrier between the inside and outside of your doors or windows,
preventing conductive thermal energy loss. Thermal break technology extends throughout the metal, protecting the inside of the door from the temperatures outside. It is because the inside and outside surfaces of the door or window are thermally separated that results in an exceptional improvement in insulation.
