Internal | Semi-Solid Masonite Flush – Durable & Heavy-Duty Interior Doors

Introduction

The Internal | Semi-Solid Masonite Flush door combines strength, security, and style. Manufactured with a slightly wider internal frame than medium-duty doors, its denser honeycomb structure enhances rigidity and weight. This makes it ideal for both commercial buildings and residential spaces requiring semi-solid doors. Additionally, these doors provide enhanced sound insulation and security, ensuring peace of mind.

Customizable & Ready for Finishing

Our Internal | Semi-Solid doors come ready for painting in your preferred color. Additionally, they comply with SANS 545 standards and undergo a SATAS-audited manufacturing process, ensuring you receive a high-quality and long-lasting product.

Construction & Available Sizes

These semi-solid doors feature a thick internal frame reinforced with a denser honeycomb structure, offering superior strength compared to hollow core or medium-duty doors. The surface—made of MDF, Masonite, or Hardboard—is hot-pressed onto the frame, creating a smooth, seamless finish that enhances aesthetic appeal.
