Doors are integral to the function of a home. They allow you to go back and forth from one room to the next, and they keep those nasty bugs and birds out. But there’s a lot about them that we don’t know and probably never realised. 

If you’re building or renovating your home, you’re probably contemplating what type of door to go with. Should it be an external door? Or should it be internal?

That’s exactly what we’ll cover in this article. However, to save you the trouble of sifting through such a detailed content list here is a quick article covering the 10 things you didn’t know about internal doors.

Internal Glazed Doors Can Be Customised

Internal doors can be customised to fit any space; this is something that many people aren’t aware of. Choose from a number of different styles, including folding doors and sliding doors. You won’t need to worry about having a door that doesn’t fit the opening.

Internal doors don’t have to be boring. Whether you want to install glass panels or add beautiful woodwork, there are many options for those who want their interior doors to be both functional and beautiful.

You can check out these internal glazed doors to see some of the premium internal doors that can be easily customised to fit your unique preferences.

Interior doors don’t just serve one purpose; there are different types of interior doors. Some examples include pocket doors, closet doors, and bi-fold doors. Your internal door choices will depend on the size and style of your home as well as your personal preferences.

They Need to Be Maintained

Internal doors are an important part of a home – they provide privacy, warmth, and noise reduction. They also come in a range of styles and finishes that can create a mood or look for each room.

Unfortunately, not all internal doors are taken care of as much as we would like. Over time, wooden doors will become scratched, faded, and discoloured.

The best way to maintain the appearance of timber doors is by applying a clear varnish or similar finish every two years or so. If your internal doors have been painted previously, they may need the paint removed and re-applied periodically.

You Can Install an Internal Door Yourself

While it may be a daunting task for most people, installing an internal door yourself is relatively easy if you know what you’re doing.

It’s important to note that while installing an internal door yourself may be relatively straightforward, some issues may arise during the installation process, which could make your life difficult. So, it is crucial to make sure that you first learn how to do it correctly.

The installation process is virtually identical, whether it’s a solid oak internal door or a more contemporary style like our glazed walnut doors or even a white primed internal door.

Moisture Content Can Affect Internal Doors

If you have a new internal door, the moisture content should be around 6-9%. If the moisture content is higher than this, the wood will expand, resulting in swelling and warping of your door.

If the moisture content is lower than 6-9%, you may notice that your door starts to shrink. This can lead to gaps appearing between the frame and door or even cracks appearing in the door itself.

Maintaining a stable humidity level within your home will help prevent these problems from occurring.

If you are looking to get new internal doors, you can choose from a number of different materials. You may be surprised by the wide array of choices that you have when it comes to internal doors.

This includes wood, glass, and even metal. The type of material you choose will depend on the interior design of your house and your personal preference.

It is important to keep in mind that the type of material that is used for your internal doors can affect their price as well as their appearance.

Internal Doors Can Save Energy

Internal doors do more than just offer privacy and protection to an interior space, they can help save energy too. Firstly, if you want to insulate your home properly, you must make sure your doors and windows are all draft-free.

This means checking the seals, locks, and hinges on your internal doors and ensuring they are tight-fitting so that there is no gap where air can enter.

Secondly, you need to think about how much air you have circulating in your home. If it’s too hot or too cold, you’ll be spending a lot of money trying to keep the house at the right temperature.

This is where internal doors made from the right material can really help – for example, composite internal doors are ideal for saving energy as many of them have a thermal core that retains heat for longer.

Thirdly, if you want to save money on heating costs, you need to make sure that the heat you do generate within your home stays inside for longer without escaping through walls or ceilings.

The best way to achieve this is by investing in high-quality composite internal doors to keep out any drafts and prevent heat loss while still allowing air circulation.

Can Elevate the Look of Your Home

Doors have the potential to make or break the aesthetic appeal of your home. Often, homeowners focus on exterior doors and forget how many internal doors can elevate the look of their homes.

Internal doors help to add a new dimension of style to your home’s overall aesthetic appeal. With internal doors, you can choose from a wide range of designs and styles, including flush doors and panelled doors.

Most interior designers agree that panelled doors are better than flush doors when it comes to adding an element of aesthetic appeal to your home.

This is because panelled doors come with indentations or panels that offer a new dimension to your home’s overall design scheme without compromising its overall visual appeal.

Can Be Soundproof

If you live in a noisy neighbourhood or have children at home, chances are that you need to find a way to soundproof your house. If you’re planning on redesigning your house, you might be looking for ways to soundproof the rooms.

Soundproof doors are a great option for achieving noise reduction in your house. They provide an easy way of reducing the noise levels by up to 60 decibels.

A soundproof door will help keep the noise out while keeping the cool or warm air inside. This means that you won’t have to use your air conditioner as much, cutting down on energy consumption and saving on energy costs.

Internal Doors Can Impact the Value of Your Home 

It’s quite likely that you’ve never even considered the impact of internal doors on the value of your home unless you’re planning to sell any time soon.

Buyers will be more interested in your property if you have solid oak doors rather than hollow-core ones. The same applies to glazed doors and panels too. Some buyers will be looking for specific styles, and these can increase the value considerably.

If you have an old door in your home, then it might be worth considering replacing it with something new that matches the rest of your décor and also adds value to the property.

This will help to put off potential buyers from trying to haggle on price, as they know they are getting a good deal when they purchase.

Inefficient Glazed Doors Waste Energy

While many homeowners may not be aware of the negative effects of poor-quality internal doors, a leading door manufacturer has revealed how this issue could be costing you money.

Inefficient glazed doors waste energy, which means your household bills may be higher than they need to be. If your door is not thermally efficient, warm air escapes from your house, and cold air gets in.

This upsets the balance of your heating system, resulting in higher costs during the winter months.

So if you want to save money on your home heating and reduce your carbon footprint at the same time, ensure that any internal doors you buy are thermally efficient. Of course, you will want to choose a style that complements your interior design scheme and is built to last.


Internal doors are one of the most underrated home decor pieces out there. They do their job, and they do it well. But while they’re not very flashy, they can make a huge difference in how your home looks, feels, and functions.

If you’re looking to learn more about the ins and outs of internal doors and how they work in homes today, we hope this list has helped.
