That's where the expertise of Greenply comes in to provide you with waterproof wooden doors that are not only durable, but low maintenance, hygienic, and absolutely safe. 

What Makes a Door Waterproof or Water‑Resistant Door

First things first, you must know what comprises waterproof doors to make a wise decision, especially when it comes to apartment door design. We all want our space to look cosy and in sync with our aesthetics. In this case, it becomes more important to know which material, surface treatment, and frames to choose. 

Material & Core Construction

  • First is Boiling Waterproof Grades (BWP/BWR). In such plywood or blockboard, the bonding resin and the core are designed to resist boiling water and even prolonged exposure to humidity. 

  • Then we have solid filler cores or cross-core compositions, which help in reducing swelling of the apartment door design, which happens because of exposure to moisture. 

  • Finally, Wood plastic composites (WPC), UPVC, or treated PVC waterproof doors, which are even better in moisture resistance. 

Surface finish 

  • What truly makes waterproof doors is their proper sealing, lamination, or membrane finishes.

  • Then we have paints and coatings that are also water-resistant. 

  • And finally, waterproof doors also come with edge sealing, be it top, bottom, and sides  to prevent any moisture through the grain. 

Frame Materials used in waterproof doors

  • Water-resistant doors are equipped with treated wood that can be PVC or UPVC, which make up the frame of the doors. 

  • Weather strips, threshold bars, and sealing around the frame are also components of waterproof wooden doors.

  • In the case of bathroom doors, ensuring correct door swing in relation to the slope of the bathroom floor is important to avoid contact with standing water. 

Where & How to Use Waterproof Doors in Apartment Design

Waterproof doors installation in an apartment can be categorized into four categories: bathroom, kitchen/pantry, balcony/terrace, and the apartment's main door. Let’s understand which waterproof wooden doors to install in each of these areas.

  • Bathroom doors: the bathroom waterproof doors must be splash, humidity, and steam resistant for all the obvious reasons. The material to be used can be WPC or BWP plywood. Both are water-resistant and coated with sealed edges. 

  • Kitchen/pantry doors: The doors in these areas are also susceptible to exposure to humidity and grease. The material used in waterproof doors should be smooth and easy to clean. 

  • Balcony/terrace doors: along with being waterproof, the doors should have an excellent core, weather-proofing, and protective paint finishing.

  • Apartments' main doors: these doors are also exposed to the world outside and may get damaged or swell because of the moisture and direct exposure to rainwater. However, at the same time, these doors demand aesthetic appeal as it's the entrance to the house. So using waterproof wooden doors or treated flush doors is a must. 

What to Look For When Buying Waterproof Doors : A Checklist

Here’s a checklist that will help you find the right type of waterproof doors for your house. 

  1. You need to figure out which grade of the core you want for your house, for example, BWP, BWR..

  2. Material type, which could be wood, plywood, flush doors, WPC, PVC, or UPVC 

  3. Then comes the thickness of your waterproof doors, which should be in alignment with the frame and the hardware that will support the door against the wall.

  4. Also, see if the edges that are top, bottom, and sides are sealed or treated. This will protect the doors from moisture ingressing into them.

  5. Finishing and designing also play a major role, as you would want your doors to go with the aesthetics of your house. Whether it's a plain flush door or one with decorative panels, you must get a door that is much like the interior decor of the house.

  6. The waterproof doors that you have installed will be of no use if the hinges, locks, and handles are not of the same quality. So make sure that you get the hardware of the same or even of a better quality, as the very existence of the door depends on it.
