My Buying Guide on ’18 Inch Interior Door’

As someone who has recently gone through the process of buying an 18 inch interior door for my home, I understand how overwhelming it can be with all the different options and factors to consider. That’s why I have put together this buying guide to help you make the best decision for your home.

Types of 18 Inch Interior Doors

The first thing you need to consider when buying an 18 inch interior door is the type of door you want. There are three main types of doors: solid wood, hollow core, and solid core. Solid wood doors are made from a single piece of wood and are the most durable and expensive option. Hollow core doors have a cardboard honeycomb center covered by thin plywood or MDF panels, making them lightweight and affordable. Solid core doors have a wood or composite core covered by a layer of MDF or plywood on both sides, providing better insulation and soundproofing compared to hollow core doors.

Materials

When it comes to materials, there are various options available such as wood, fiberglass, and steel. Wooden doors offer a classic and elegant look but can be prone to warping and require regular maintenance. Fiberglass doors are highly durable, low maintenance, and can mimic the look of wood. Steel doors offer excellent security but may dent easily.

Style

The style of your interior door should complement the overall aesthetic of your home. Some popular styles include panel, flush, barn-style, French-style, and pocket doors. Consider the functionality of the room when choosing a style – for example, pocket doors are great for saving space in smaller rooms while French-style doors add an elegant touch to living areas.

Door Hardware

Door hardware includes handles/knobs, hinges, locks, and latches. Make sure that the hardware you choose matches the style of your door and provides adequate security for your needs.

Budget

Before starting your search for an 18 inch interior door, it’s important to set a budget. Doors can range from affordable to quite expensive depending on material quality and customization options. Consider what features are most important to you when setting your budget.
