Collection: Door Thicknesses 44mm

Door Thicknesses 44mm helps you filter to sizes that fit first time. Browse modern, shaker, panelled, and glazed looks across materials from oak to durable laminates. Solid and semi solid cores improve feel and sound control, with fire rated options where specified. Standard sizing streamlines replacements, refurbishments, and whole home planning. We supply nationwide with clear lead times, and offer optional professional fitting for accuracy, warranty protection, and a clean finish. Use filters by style, material, size, and glazing to compare quickly and order with confidence.
