Types of Doors: Options for Interior and Exterior

We must evaluate several issues when choosing a door: materials, security, opening, design, etc. Know the options and choose the ideal one for you.

Both in terms of safety and design, materials and aesthetics, there are several types of doors for the interior and exterior of the home: wood, aluminum, iron, armored, with folding or sliding system and several other options. Everything you need to know and evaluate to choose the one that best suits your needs.

The doors are classified according to their material and their opening. They also have different levels of security, especially in the case of exteriors, and there are many variants at the design level. To find the one that best responds to what we are looking for, it is essential to review all the models and know their qualities. We tell you everything you have to know.

Entrance or exterior doors

When we choose an entrance door we want it to be safe and look good. That is why it is important to look for models that cover both the aesthetic and functional aspects. The most popular are:

Sheet metal doors

They are a good option for those who have a modern decorative style and aspire to achieve an optimal combination of beauty, quality and safety. It is recommended to look for a filling with polyurethane injected under heat or one with electro-galvanized sheet. The latter also greatly facilitates the hygiene process.

Iron door

An iron door as an entrance to the home is elegant and generates distinction. This opening style combines with any type of decoration and is extremely safe thanks to the weight of the material. At the same time, it has an extensive shelf life and it is very difficult for it to be damaged or corrupted. The only drawback is that it is an expensive model, but given its benefits it is a good investment.

Armored doors

They are the safest option since it is a wooden door that has metal plates incorporated on both sides, which makes them very difficult to open, even using a lever. In addition, they are heavier and act as an insulator of sound and temperature, which can be key in case of fire. But not all that glitters is gold: this type of door is expensive and, therefore, choosing it requires a significant initial investment.

Aluminum doors

They are one of the most popular alternatives thanks to their excellent balance between price and safety. Without being armored or armored, these openings are very resistant. In addition, aluminum requires very little maintenance, is easy to clean and has a good performance in tightness and tightness. In terms of aesthetics, they have an enormous facility to adapt to all styles and are one of the most sold in the Argentine market.

Wooden doors

They are the perfect option for those looking for a rustic, classic and elegant style. They are the most decorative choice and enhance the facade of the home, although they are not the best alternative in terms of safety, especially if they do not have metal reinforcements. Luckily, there is the possibility of coating the wood with veneer, which makes it more resistant and helps prevent climate deterioration.

Interior doors

The case of indoor models is different because safety considerations give way to questions more linked to practicality and decoration. For the internal openings of the home we can find a wide variety of solutions with different types of openings, material and designs.

Its main function is to separate environments to create privacy between one room and another. The choice depends largely on the use we give and the space we can take advantage of.  The most common types of interior doors are:


When we talk about folding models we mean the classic door with a frame that opens diagonally, inward or outward. It is the most common model of all and the most used.

They are reliable and adapt to all decorating styles. However, if we want to save some meters, it may be best to resort to other more modern models.


If what we want is to gain space, this is the best option. Although its installation is a bit more expensive, they do not take place when opened and come in different models.

Built-in slides: this type of opening integrates perfectly with the wall, but it cannot be installed without making a “hole” between the cardboard and plasterboard.

Overlapping slides: they have the advantage of working in the same way as the built-in ones without the need to do any work. They are suspended from a guide fixed at the top of the wall and open to the side. Its installation is super simple and they are not expensive. The guide can be visible, in a barn-like gate style – more rustic – or covered with a door tone box.


It is a door with a leaf, whose main characteristic is that it moves from one side to the other with just a push and always returns to its original position. Although it is not a very common choice, it can make certain areas of the house look more interesting. The kitchen or the laundry can benefit a lot with an opening of this style. In addition, it is easy to install and is not expensive.

Folding or folding

Another interesting option if we want to save space is the folding or folding. They consist of several sheets that fold over each other to allow passage. They do not need space for the turn or work to install them. In addition to optimizing the space, they enable different designs and materials. You can look for a model with glass to give it a modern touch that lets light shine into the environment.

Indoor models according to their material

Another point that we have to take into account when choosing interior models is the composition material. The most common are wood and aluminum. We tell you what are its advantages and disadvantages.

Wood:  one of the most used materials is wood, for its aesthetic potential. It is very tough and durable but can be very expensive.

Aluminum: aluminum is an excellent alternative, since it adapts to any style and offers great resistance. In addition, it is easy to maintain and clean.

Wood and veneer: these are models that use wood for the interior of the door and then cover it with veneer to save costs.

Hollow: they have their interior made of honeycomb panel. They stand out for their lightness, although their robustness and their thermal and acoustic insulation is less than that of solid wood. They are covered by a wood veneer between 3 and 5 mm and are surrounded by a wooden frame.
