When choosing black composite doors from Emerald, not only are you guaranteed a visually appealing door that will suit any home, you can enjoy a selection of excellent practical benefits. As we supply three different types of composite door, Distinction, Solidor & Infinity, their practical qualities differ slightly. However, each is equipped with a hardwearing Glass Reinforced Plastic exterior for a damage resistant, weatherproof door and either an ultra-dense foam or solid timber core, for an incredible thermal performance. Additionally, they’re one of the securest types of entrance door on the market.
