Interior Door Core Types

At DoorStop, we sell commercial interior wood doors with hollow cores and solid cores. Our selection of core types includes the following.

"Diet" Core

Our "Diet" lightweight solid core for doors combines the benefits of hollow and solid cores. Diet core has a solid core construction and features materials that result in a lighter core. It has a low average ratio for pounds to square feet that makes a solid core door easier to install and use. You can find this special core only in our distributor catalog.

 

Find out more about our one-of-a-kind diet core by reading the specification sheet.

Particleboard

We can also use five-ply particleboard in our solid core commercial doors. This material consists of recycled wood fiber that makes a door more cost-effective and environmentally friendly. Particleboard meets a wide range of construction requirements, and many professionals consider it an industry standard. Its availability and affordability make it an accessible choice.

Learn more about our particleboard cores on our official data sheet.

Structural Composite/Laminated Strand Lumber (SCL/LSL)

Also known as laminated strand lumber (LSL), structural composite lumber (SCL) includes strands of wood connected with laminate. This wood and plastic core for doors has a higher strength than particleboard. SCL can reduce the minimum dimensions needed to install a lite or lock onto a door compared to a particleboard door.

Discover more about SCL cores on our specification sheet.

Fire-Rated

Let us add fire resistance to almost any door in our catalog with our fire-rated cores. We have cores that are fire-rated for 20, 45, 60 and 90 minutes. The core types have a different material options::

  • 20 minutes: Particleboard LD-1 or LD-2 in compliance with ANSI A208.I

  • 45 minutes: SCL in compliance with ANSI A208.I up to 96 inches, mineral core over 96 inches

  • 60 & 90 minutes: Non-asbestos mineral core engineered to label specifications

Fire-rated cores have their own specification sheet. Read about our 20-minute45-minute and 60 & 90-minute fire-rated five-ply core.

Standard Hollow Core/Honeycomb

"Honeycomb" or standard hollow door cores, consist of corrugated material arranged in cells. This honeycomb pattern provides structure while keeping the door lightweight. Our hollow core doors have 4-inch by 4-inch hexagonal cells. A hollow core maximizes the door's use of materials, making it a cost-effective option.
