If you want to enhance your home or office in this way, the most critical part is to set up a sturdy frame at the bottom. Take care to do it correctly since this part will carry the weight of the doors.

You can also install a pocket or bi-folding door for this purpose. These options are highly useful for a small studio or ‘secret’ wardrobe. If the space is vast and high, you can add transoms on the top to enable light to go through.

Sliding Door Maintenance

You should maintain the door by cleaning the track and rollers at least once a month. Make sure that the seal doesn’t break since it will lessen the insulating power. The rule is the same for the interior sliding doors because most of the dirt can fall into the tracks and disable them to move correctly.

In the case of exterior sliding doors, most companies will offer a lifetime warranty against distortion, peeling, corrosion, cracks, and damages on the glass seal. Keep in mind that it doesn’t include the influence of sunlight or air pollution on the frame, the wrong installation, and misuse of the door.

Luckily, the available door choice is vast, so you can effortlessly beautify your home and enjoy it.
