To look at them, you could easily think that, but they’re not. The average depth of a standard composite door is 44mm and it typically contains a foam filling. Generally lightweight, it will also feature a GRP colour skin (also known as fibreglass).
A Solid Core composite door is considerably thicker, with a depth of about 48mm. Manufactured using many laminated layers of timber, it’s way more durable and rugged than a foam filled composite door. The UPVC skin it has makes it easy to colour match the design with your door frame.
