What is a Hollow Door?
A hollow door is a lightweight door used mainly as an interior door due to its lack of security. Hollow core doors do not provide the same weight and feel as a solid core door, however they are a simple and affordable option that still manage to serve their general purpose.
Are Hollow Doors Really Hollow?
Although they are called hollow doors, the inside of these doors are not completely empty as one would think. Inexpensively constructed out of veneered scrap wood, the actual filling for a hollow door varies, ranging from structural cardboard to foam insulation; added to provide additional support and structure to the hollow door frame. However, even with the additional insulation--hollow core doors are still not a good choice for the exterior of your home due to their inherent flimsiness. The thin quality of these doors carry and deliver sound as well, limiting the privacy of a room, therefore they may not be an ideal choice for office or study areas either, as absolute quiet is usually necessary.
Best Installation Purposes
Not all home hardware needs to be of the finest quality, and therefore more expensive. Great areas to use hollow core doors in include: closets, playrooms, kitchens, and other areas where sound insulation and security are not an issue. Due to their lightweight material, these doors are less prone to warping and many people are finding creative uses for hollow doors, such as drawing/party tables, room dividers and even islands for the kitchen.
When used correctly, hollow core doors can be a wonderfully affordable interior door alternative. The hollow core door is even considered environmentally friendly, as scrap woods that would normally go to waste are now being used to manufacture these doors. Don't judge this door by it's interior; with many useful purposes and benefits this is one door option you should always be open to!
