Inside doors, also called interior doors, are doors that opens up one interior space to another with no access to the outside, such as doors for the bedroom, bathroom or closet. Just like how the front door is the first thing you see when entering the house, the interior doors will serve as first impressions for your rooms or individual spaces. Picking out the right inside door with suitable functionality and appearance will be a significant statement to the home.
With inside doors serving several different interior spaces, there are many options of door types to choose from, where some are more suitable for large areas and some for smaller areas. Let’s take a look at their different characteristics below:
Passage Doors – Passage doors are the most commonly seen doors in residential spaces. Either the left or right side of the door is hinged to the wall, and the other side swings to open and close. The space in which the door swings to will need to be free of objects and furnitures. Passage doors can be flush doors, which are completely flat, or panel doors, which has square or rectangular panel patterns.
Sliding Doors – Sliding doors are two or more doors placed next to each other on a track, which can be slided to one side to overlap and create an opening. Sliding doors are less seen in houses as room doors but are popular as closet doors. They are useful for places without much space, but will always have part of the opening obstructed.
Louver Doors – Louver doors consists of a door frame with a number of angled narrow slats placed horizontally within the door frame, just like louvered shutters. They are also a common option for the closet and laundry room, due to their ventilation and thinness. Some louver doors are combined with a panel door for both style and functionality.
Bifold Doors – Bifold doors are two doors hinged together, making it foldable into each other. These are mostly used for closets, kitchen pantries and laundry rooms. Bifold doors are a good option for smaller places like sliding doors, however providing more opening space since the doors can be completely folded to the wallside.
Pocket Doors - Pocket doors are essentially sliding doors that disappears into the wall’s slit. They are the best way to save floor space, and are very popular for bathrooms. Pocket doors can be either single, with one door sliding into either the left or right wall, or double, with two doors sliding each into the two sides.
French Doors - French doors consists of two doors placed right next to each other, each hinged at the side of the opening. The set of doors swings open together from the centre, creating a large opening space with unobstructed view. It adds a more dramatic and grandiose touch to the home and entry style. French doors are usually used in a larger space for a display room.
Solid Wood - Solid wood doors are pure wood doors that are sturdy, strong and also the heaviest. They have a great aesthetic appeal that creates a warm tone for the home, as well as functionality of offering insulation and sound barrier. These benefits do come with a higher price of quality solid wood doors with mostly a few hundred dollars, however their long-lasting features can be of good value.
Solid-Core - Solid-core doors has a similar look and feel to solid wood doors, but are made with a wood fibre core and an exterior of plywood of composites. They are decently sound proof and durable, also a good insulator. Solid-core doors have similar qualities to solid wood doors but are more affordable. They are generally priced around $150 CAD to $300 CAD.
Hollow-Core - Hollow-core doors has a rigid cardboard core with plywood or hardwood exterior. This is the lightest and cheapest option, which can be found at as low as $40 CAD per door slab. However it is not as durable or sound proof. Hollow-core doors are a good option for houses with heat and humidity fluctuations as they are more resistant to warping and swelling than doors with wood core.
If you have decided to pick a wooden interior door, in which many homeowners do, applying a finish is extremely important and will help in maintaining the door. Or if you like the wooden material but are unsure due to its potential damages, the finish is also beneficial in protecting the wood from these damages including warping due to moisture. Looking for a professional is the safest way to apply a beautiful finish to your door, but if you prefer some hands-on work, make sure to follow the steps below.
Before the finishing process, prepare the door by hanging it in place for at least two days to allow it to adjust to the environment’s temperature and humidity. After the pre-hung, you can take it back down and start the finishing process.
First clean the door thoroughly, wiping it down with cloth. You can use acetone for a more comprehensive clean. Next, check if there are any scratches, and if so use sandpaper to remove them. Remember to clean up the debris from sanding afterwards.
Apply a first coat of primer, which can be either a clear stain or custom tint depending on your choice of the door’s look. Also make sure you differentiate between using an oil-based primer and finish, and a latex-based primer and finish. Apply a second coat of primer after the first coat dries.
Apply the finish after the primer dries, and have at least two coats of finish. You can apply more for an effect of deeper hue for the wood. Make sure to cover all sides of the door, and apply each coat only when the previous dries.
Inside doors are not complete without their hardwards to support their functionality. Door hardwards generally include two different elements, the lock and the door knob or handle. Locks are extremely important for security and privacy. Even though interior doors are not as exposed to invasion as front doors, inside door locks still serve as an additional line of defense, as well as keeping the room enclosed when privacy is needed. There are several different type of locks available for doors, with a knob locks and lever handle locks most commonly used for interior doors. These are simpler keyed door locks that can be operated from both sides, preventing accidental lockout.
The door knob is another crucial hardware component to interior doors, especially for passage doors. The door knob or handle provides a grasp for users to hold onto and turn in order to open the door and gain access to the areas. Some door type such as sliding doors or folding doors may not necessarily need a door knob to operate, with some having a handle area crafted into the door itself.
