Your front door is the face of your property. It’s the first thing you see when you arrive home in the evening, the last thing you see when you leave in the morning and the sight that welcomes your visitors setting their first impression.

Composite Doors are made from a variety of materials, including uPVC, wood, insulating foam and glass reinforced plastic (GRP). This combination of materials results in a very strong and secure door. Liniar composite doors have a high resistance to weathering and don’t react to seasonal changes like a singular material door would. The insulation foam core provides a higher thermal resistance than timber doors. Liniar composite doors are designed with an attractive woodgrain appearance but, because of the materials used, they won’t fade or discolour – and neither will they need painting, and don’t warp in damp conditions.

Whether your home is a rural retreat or on a busy main road, a Liniar composite door guarantees low maintenance with secure and enduring performance. If you are seeking to replace an existing door or add some character to your property, Liniar is sure to have a solution. Liniar composite doors are not only aesthetically pleasing and lead-free but have been designed with security in mind.

Composite doors are available in a wide range of colour options to give your home a stunning appearance. Colour options for both the door and the frame include White, Cream, Rosewood, Light Oak, and Irish Oak, as well as Grey, Black and Chartwell Green.
