All XL internal oak doors are of engineered construction. Benefits of engineered over solid oak:
– Less susceptible to movement than solid oak doors
– Better colour match as all door components are veneered
– Better utilisation of timber = better for the environment, less wastage
– More resistant to environmental fluctuations, e.g. cold and cold rooms during winter heating cycles.
Our dowelled hardwood doors are manufactured from kiln-dried timber and are jointed using fluted dowels and modern adhesives.
Our mortice & tenon doors are manufactured from select kiln-dried hardwoods and are constructed using traditional mortice & tenon joints and modern adhesives. This ensures that the doors are constructed to the very highest standard. The panels are set in waterproof mastic ensuring that the highest level of weatherproofing is achieved.

An intumescent strip is a component of a fire door. It is placed around the door frame and is chemically designed to automatically expand when exposed to extreme heat, thus sealing the gap around the frame. This therefore contains the fire and allowing for enough time to escape.
This is very important as isolates the fire to one particular area and helps to protect people whilst also minimises damage to the building itself.
It differs from a smoke seal as that is used to block smoke and not contain a fire. We offer a range of options for our internal fire doorkits.
A smoke seal is basically a barrier on fire doors that prevent the flow of deadly and hazardous fumes travelling from room to room. It works by being placed between the door frame and the door on all sides. By preventing smoke from passing through the gaps between the door and frame, allows more time to escape as the rest of the building is not affected by heavy smoke.
It is important to have a Smoke Seal as inhalation of smoke kills more people than fires do! An is an effective but easy means of preventing this from happening.
A smoke seal works differently from an intumescent strip, as it prevents the smoke from spreading whereas an intumescent strip blocks off the fire itself.
