If you have bought doors or checked prices of doors in warehouses or online stores, you have probably noticed that there are doors labeled as exterior doors and some that are labeled as interior doors. There are several differences between these doors apart from their location on buildings. Read on to find out what differentiates exterior and interior doors.
Exterior Doors are Thicker
Because exterior doors serve as security barriers, they tend to be way thicker than interior doors. Apart from them also serving a security purpose, these doors are subjected to a lot of wear and tear. Because of that, they require an extra thick core. This enables them to keep out the heat and cold as well. For them to contribute to temperature control, exterior doors should include a thick layer of veneer to improve insulation. On the other hand, interior doors do not have to withstand harsh weather conditions. They are made lighter since they are used more frequently. Interior doors are usually 1 3/8 inches thick.
Core Construction
Exterior doors serve as a barrier between the outdoors and the interior. This is why they need to be constructed with a solid core. For maximum temperature control and added security, exterior doors consist of a wooden core that’s surrounded by several layers of steel or metal. On the other hand, that thick core is missing on the interior doors. Instead, they have a hollow core. You will only find a honeycomb-like inner core on more expensive interior doors. This structure is meant to help with soundproofing.
Insulation Differences
Apart from serving as a strong barrier between the interior of your home and exterior, exterior doors also have to protect the indoors from harsh weather conditions. This is why they have a multilayered structure. You will find this type of structure on both wooden and steel doors. Steel doors are made with a foam core to help regulate temperature.
Exterior Doors are Generally Larger
You will often find that main entrances have a larger opening than doors between interior rooms. This is why exterior doors are usually larger and heavier than interior doors. Apart from having larger dimensions, exterior doors are also thicker. Unlike interior doors, they are made with function in mind instead of usability.
These are some of the differences between exterior and interior doors. It’s important to do your research before you buy any type of door. If you are not sure which door to choose, get in touch with us today.
