In some environments such as schools and hospitals it is desirable for vision panels to offer both a security and a privacy solution.
Fire resistance is one of the most fundamental performance criteria for fire doors and doorsets, resulting in a complexity of interrelated regulations, standards and guides
Fire resistance is one of the most fundamental performance criteria for fire doors and doorsets, resulting in a complexity of interrelated regulations, standards and guides.
Acoustic control within buildings using acoustic doors can be a complex area traditionally involving either specialist consultants or a purely subjective approach
A wide choice of high performance security doorsets has been developed by Leaderflush Shapland for situations requiring resistance against forced entry, vandalism and more serious burglary or armed attack
Various documents, including BS 8214, stress the importance of specifying the appropriate classification of doors to ensure long-term performance under anticipated uses.
With hygiene being such a critical factor across all sectors, Leaderflush Shapland introduce Hygienlic, an anti-bacterial finish for infection control in doors and doorsets
Leaderflush Shapland has developed the Leadline range of doorsets providing various levels of X-ray protection while accommodating all the standard Leaderflush Shapland facing options
Issues to consider include the adoption of factory-assembled doorsets to improve environmental efficiency, techniques to maximise operational design life and, particularly, use of verifiable sustainable timber sources.
As a business we set high standards of environmental performance across all our manufacturing sites and work closely with our supply chain to play our part in conserving the world�s natural resources
As a natural, organic, renewable material that is also recyclable, waste-efficient, biodegradable and non-toxic, timber has many environmental advantages for the building industry - and doorsets in particula

acoustic doorsets
Introducing acoustic doorsets
The Audiodor range of flush doorset constructions have been developed to meet acoustic performance requirements above other Leaderflush Shapland product ranges. These acoustic doorsets incorporate the latest construction and seal techniques to ensure high levels of sound reduction, while taking into account other performance characteristics including:
Fire resistance, independently tested and accredited within the BWF-CERTIFIRE scheme.
Smoke containment, as acoustic seals negate the need for additional smoke seals.
Mechanical strength and durability, either Severe Duty (SD) or Heavy Duty (HD) in accordance with BS DD171.
Ease of handling and installation with lighter weight doorsets.
Performance
The effects of acoustic privacy and nuisance noise are subjective and influenced by background noise within the room, distance from sound source and general context, amongst others.
When considering walls containing doors, it is the combined performance of both elements that is relevant, clearly the proportion of door to wall area is particularly important.
The following table provides some general guidance on acoustic privacy in relation to sound reduction:
RwdB
Effect
25
Normal speech easily overheard
30
Loud speech clearly overheard
35
Loud speech can be distinguished
40
Loud speech heard but not intelligible
45
Loud speech heard faintly
50
Loud speech and shouting can be heard with difficulty
Central to the successful achievement of required acoustic levels is the specification of complete engineered doorsets, where all components are factory-assembled to the closest tolerances and test-proven, as opposed to site-assembly of disparate components. In addition, best practice on site is critical, sound is like water in that all gaps must be properly sealed to stop leakage (see Achieving Performance on Site).
Acoustics is a complex field and a wide variety of performance levels sometimes referred to including NR or NC levels and dBA, RwdB and STC. Acoustic performance for doorsets should always refer to RwdB. It should be remembered that performance values quoted for products and ranges are based on laboratory test results; on-site testing will generally produce lower results.
Further technical information on acoustic performance of doorsets – including the implications of Part E of the Building Regulations – is available from our Technical Services Department.
All Leaderflush Shapland acoustic doorsets incorporate appropriate combinations of high performance acoustic frame seals (common throughout the range) and bottom edge-of-door seals, with low-profile aluminium thresholds to minimise accessibility difficulties. Each particular door leaf construction has been acoustically tested with its frame and associated seals, and designated for ease of selection.
Acoustic doorsets can accommodate many of our standard vision panel designs – all factory glazed (with glass to suit acoustic and fire performance) using fully sealed glazing beads.
