Installation and fitting

Door lining should be installed plumb and square to the wall opening. Measure your doorway opening carefully and cut the lining to length, accounting for the floor level and any threshold. The 32mm thickness provides good structural support when properly fixed. Secure the lining using appropriate fixings (typically nails or screws) into the wall studs or masonry, ensuring it remains square throughout installation. Allow adequate clearance for the door leaf and hinges as per your door manufacturer's specifications.

Material properties and limitations

Premium Redwood is a softwood that offers good workability and an attractive natural finish. Being PAR (planed all round), it arrives ready to use with smooth surfaces. However, softwood is not suitable for external use or areas subject to moisture, dampness, or direct water contact. The material may move slightly with changes in humidity, which is normal for timber. It is not recommended for wet areas such as bathrooms or kitchens without additional protection.

Finishing and maintenance

Premium Redwood can be finished with paint, stain, or varnish to suit your décor. Sand lightly before applying any finish to ensure good adhesion. Once installed and finished, maintain the lining by keeping it clean and dry. Inspect periodically for any signs of damage or movement, particularly around fixing points. Avoid exposing the lining to prolonged moisture or direct heat sources.
