White Linear Style Internal Door

Doors are typically made by joining a wooden frame and filling it with either a solid core (for strength and insulation) or a hollow core (for lightweight and affordability). The outer surface, known as the "skin," can be made from wood veneer, MDF, or composite materials depending on the style and finish. Some doors also include glazing (glass panels) for added light or design.

What’s the difference between solid core, hollow core, and engineered doors?

• Solid core doors are heavy, durable, and great for soundproofing.
• Hollow core doors are lightweight and budget-friendly—ideal for internal rooms.
• Engineered doors combine different materials to balance strength, weight, and cost. They’re stable, reliable, and a popular choice for modern homes.

It depends on the space and your priorities. Need privacy and noise control? Go for a solid internal door. Want to let in natural light? Consider glazed doors. Unsure? Drop us an email atsales@deal4doors.co.uk—we’re happy to help!

Measure the width and height of the door opening in three places (top, middle, and bottom), then use the smallest measurement. Don’t forget to check the door thickness too. Still stuck? We can guide you—just email us!

Fire doors are specially designed to resist fire for a certain period (usually 30 or 60 minutes). They’re often required in homes with multiple stories or where a garage connects to the house. We stock a wide range of certified fire doors—feel free to reach out for advice.
