Ducts passing through fire-rated walls or floors need fire dampers.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Leased premises
If your Alfreton premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
