No, they’re not. Standard composite doors are generally 44mm in depth, and are foam filled. They have GRP colour skins (commonly known as fibreglass) and are relatively lightweight.
Hazlemere composite doors are 50mm in depth and are made of laminated layers of timber, making them more robust and durable than foam filled doors. They also have high impact UPVC skins which means you can achieve a perfect colour match with your door frame.
