Before you book in South Glamorgan
Noise
Fans and grilles are selected and attenuated to keep noise down.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Leased premises
If your South Glamorgan 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.
