# 3-Layer Solid-Core Doors

3-layer solid-core doors are an economical choice designed for strength, durability, and functionality. These doors are built to offer excellent performance in residential and light commercial applications where cost-efficiency is key and a painted finish is preferred.

- **Construction Details:**

1. **Core Layer**: The central core is made from high-density particleboard, providing the door's primary structure, ensuring excellent sound insulation and stability while resisting warping and sagging over time.
2. **Surface Layers**: Two outer layers of high-density fiberboard (HDF) are bonded to each side of the core, offering a smooth surface ideal for painting. This construction provides a uniform finish and adds to the door's rigidity.
3. **Edge Banding**: The edges are first banded with laminated strand lumber (LSL) to provide structural integrity, followed by a layer of solid wood (poplar or basswood) to enhance the door’s appearance and durability.

- **Advantages:**
  3-layer solid-core doors are strong, stable, and provide superior sound and thermal insulation compared to hollow-core alternatives. They are ideal for painted finishes in spaces where noise reduction and privacy are essential, such as bedrooms, offices, and meeting rooms.
- **Applications:**
  These doors are suited for residential projects and light commercial spaces, where a balance between cost, durability, and aesthetic appeal is needed. They are versatile and can be painted to fit various interior design styles, from modern to traditional.
