Traditional door sets
Generations of tradition and craftsmanship
combined with high performance
characteristics help to ensure the longevity
of our historic buildings.
Minimal intervention and the retention of as much of the existing
fabric as possible is vitally important to a great many projects.
The key is a combination of traditional craftsmanship, specialist
conservation experience and an innovative, highly engineered
approach to detailed design and construction.
Projects are considered individually and in detail, with Longden's
involvement being summarised as follows:
- Replacement of existing doors with new performance doors or
doorsets. These can be made to suit retained frames, architraves
and other opening details such as reveal panelling or curved
- Replacement of existing doors with new performance doors
or doorsets incorporating retained panels, carvings or other
features from original doors.
- Addition of new doorsets to accommodate revised layouts either
replicating existing or, alternatively, in a contrasting or possibly
more modern style.
In order to ensure the long-term usability and viability of historic
buildings, there may well be a requirement to meet stringent
performance standards, as indicated by today's Building
Regulations. For doors, frames, architraves, reveal panelling and
other similar elements, this can present a real challenge, requiring
a considered balance between intervention to achieve compliance
and protection of essential architectural characteristics.
The Longden range is particularly suited to the restoration
of historic and traditional buildings of all types and has been
used extensively in notable monuments and listed buildings
throughout the country. The company's approach to conservation
and its expertise in replicating original features and traditional
craftsmanship are widely recognised by architects, conservation
experts and organisations such as English Heritage.
Specific performance levels may be called for in terms of
accessibility, fire-protection, smoke containment, sound reduction
and security - particularly with a change of building use or
altered room arrangements. Whilst Building Regulations may
be relaxed in the case of listed buildings and other performance
standards waived, this approach should be treated with caution.
For example, fire-resistant doorsets are the most effective means
of protecting historic buildings from the spread of fire and
smoke, without the damaging after-effects of sprinkler systems.
Similarly, a security doorset can prevent unauthorised access
and the resulting theft, vandalism and arson. Therefore, there
is a strong case for the considered use of performance doorsets to
protect historic buildings in the wider sense.
