Materials used to make our Main doors

These are the 3 core materials that we use in our doors :

Solid wood core: To ensure your HDB main door is sturdy and secure, it has to have a solid wood core sandwiched between two hardwood layers.

Plywood: High-quality plywood panels are attached to the outer side of the solid wood; the plywood is lightweight and sturdy.

Laminate: This layer is the outermost layer you see when you look at your HDB main door. It has a ton of benefits apart from the strength you get from the wooden core.

Made with Thickness, fire-rating & Digital lock compatibility

Our doors are made with these three things in mind: Thickness, fire rating, and digital lock compatibility.

  • HDB requires at least 35 to 40mm or beyond 40mm thick solid doors, which is why our doors are the same size(40-45mm). So you can fit additional locks or other safety hardware into the door easily.
  • We assure you Thicker doors, e.g., 36mm above, are tested and approved as a fire-rated doors. Our main doors can achieve 30-60 minute Fire resistance ratings, providing greater fire safety. The fire rating also depends on the door type (e.g., Our 3x7ft main door is suitable for HDB flats and can only withstand fires for 30 minutes, making it a good option for any HDB flats. However, our 4×7 ft size main doors are suitable for condominium flats and can withstand fires for up to 60 mins, making it compatible with a condo flat.)

(Note: Please keep in mind that if you’re willing to buy a fire-rated door make sure the door comes with a government approved fire safety seal whether you are buying a door from us or anywhere)

  • If you purchase a door from us and need a digital lock for it, you must ensure that it is at least 40 mm thick to fit all digital locks.
