Interior vs Exterior Doors - What's The Difference?

Doors are an essential element of any home or building. They serve as a passage between rooms, provide privacy and security, and form an integral part of your home’s aesthetic appeal. There are two main types of doors, exterior and interior, and while they may look similar there are key differences between the two you need to be aware of. 



Different Functions


The primary difference between interior and exterior doors is their function. Interior doors are designed to separate rooms within a building, while exterior doors are meant to provide an entry point to the building from the outside. Interior doors are typically thinner and lighter compared to exterior doors, which are heavier and sturdier. This is because exterior doors need to withstand harsh weather conditions and provide security, whereas interior doors are more about aesthetics and privacy.


Exterior doors often include barriers against the outside weather, such as a threshold and weatherstripping, to prevent moisture and drafts from entering the building. They may also have a peephole, a deadbolt, and a handle with a lock for added security. On the other hand, interior doors don't require these features and may have simpler knobs or handles for easy opening and closing.



Different Costs


Another significant difference between interior and exterior doors is their cost. Exterior doors are typically more expensive than interior doors because of their added features and sturdier construction. Exterior doors require a more robust frame, hinges, and hardware to withstand weather and provide security. They may also require special finishes or treatments to prevent warping, rotting, or fading due to exposure to the elements.


Interior doors, on the other hand, can be made from less expensive materials and may not require as much hardware or finishing. However, the cost of interior doors can vary based on their design, material, and finish. For example, solid wood doors may be more expensive than hollow core doors, and custom-designed doors may cost more than standard sizes.



Different Hardware


Interior and exterior doors also differ in their hardware. Exterior doors require more heavy-duty hardware to withstand the elements and provide security. This includes a sturdy lock, handle, and deadbolt, as well as hinges and a weather-resistant threshold. Exterior doors may also have a peephole, kickplate, or door knocker for added functionality.


Interior doors, on the other hand, don't require as much hardware and may have simple knobs or handles. However, interior doors can still have a range of hardware options, including decorative knobs, levers, hinges, and latches. The choice of hardware can also affect the overall look and feel of the interior doors, allowing for customization to match the décor of a room.


Different Materials

Interior and exterior doors can be made from a variety of materials, but they differ in the type of materials used. Exterior doors are typically made from more durable and weather-resistant materials, such as wood, fibreglass, or steel. These materials can withstand exposure to the elements, resist warping or rotting, and provide added security.

Wooden exterior doors are a popular choice for their aesthetic appeal and natural durability. They can be customized with a range of finishes, stains, or paint colours to match the style of the building. Wooden exterior doors also provide a classic look that adds value to a home and can last for years with proper maintenance.

Interior doors, on the other hand, can be made from a wider range of materials, including wood, fibreglass, steel, or even glass. Interior doors are often designed with aesthetics in mind, allowing for a range of styles, finishes, and textures to match the décor of a room. Wooden interior doors are also a popular choice for their warmth and natural beauty, as well as their ability to reduce noise and provide insulation.



Benefits of Wooden Exterior and Interior Doors


While there are many materials to choose from for both interior and exterior doors, wooden doors offer several benefits that make them a popular choice. Here are some benefits of wooden exterior and interior doors:

Durability: Wooden doors are durable and can withstand the wear and tear of everyday use. With proper care and maintenance, wooden doors can last for many years, making them a long-term investment.

Energy Efficiency: Wooden doors provide natural insulation, helping to reduce heat loss and lower energy bills. They also reduce noise transmission, making them ideal for use in bedrooms, home offices, and other quiet spaces.

Aesthetics: Wooden doors have a natural beauty that can enhance the overall look and feel of a home or building. With a range of finishes, stains, and colours to choose from, wooden doors can complement any décor style.

Value: Wooden doors can add value to a home or building by increasing its resale value, while they may be expensive upfront they yield a positive return on investment over time. 



Choosing the Right Exterior and Exterior Doors for Your Needs 


Understanding the differences between interior and exterior doors is essential when selecting doors for your home or building. Exterior doors require added durability, security, and weather resistance, while interior doors focus on aesthetics and privacy. 

Wooden doors offer several benefits, including durability, energy efficiency, aesthetics, and value, making them a popular choice for both interior and exterior doors. When choosing doors for your home or building, consider the function, cost, hardware, and materials to ensure that you select the right doors for your needs.

Hi everyone I am Emily Naomi wanna give a big thanks to this wonderful psychic for bringing my husband back to me… I never really believed in magic spells or anything spiritual but a trusted friend opened my eyes to the truth about life. My marriage was heading to divorce a few months ago. I was so confused and devastated with no clue or help on how to prevent it, till I was introduced to this psychic Priest Ray that did a love spell and broke every spiritual distraction from my marriage. A day later my husband started showing me love and care even better than it used to be, he’s ready to talk things through and find ways for us to stay happy. It’s such a miracle that my marriage can be saved so quickly without stress. You can also contact him for help by email [email protected] or WhatsApp: +12133525735 and you can also visit his website:
