Fans and grilles are selected and attenuated to keep noise down.
Working hours
Most Shirley businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Leased premises
If your Shirley 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.
