Hollow doors are typically constructed using thin wooden strips, with a central frame made of solid wood or plywood. This design gives the door a lightweight structure but also makes it more prone to warping over time.
One major drawback of hollow doors is their weak sound insulation. However, they are less likely to deform compared to solid doors. To improve soundproofing, you can increase the thickness of the splints on both sides or add additional layers of material.
In modern construction, especially in urban areas, fire-rated doors are commonly used. These are a type of hollow door, but instead of regular wood, they use fire-resistant materials like fireproof cotton and foam to enhance safety.
Despite their lower soundproofing capabilities, hollow doors remain popular due to their cost-effectiveness and ease of installation. They are often chosen for interior spaces where noise control isn't a primary concern.
