Frequently Addressed Technical Enquiries
Clear technical answers regarding British Standards compliance, operational containment, and delivery parameters for commercial clients across Norfolk.
What is the difference between a Cat A and Cat B commercial fit-out?
A Cat A fit-out provides the basic functional interior framework required by commercial landlords (raised floors, basic ceiling grids, lighting, core air handling, and compliant washrooms). A Cat B fit-out completes the workspace for an incoming tenant, adding private meeting rooms, bespoke acoustic partitions, branded finishes, tea points, and furniture integration.
Can commercial refurbishments be carried out in occupied office buildings?
Yes. We operate phased delivery schedules, night-shift working, and acoustic dust hoarding to isolate active construction zones, ensuring that office tenants and commercial personnel can continue daily operations safely and without noise interference.
What acoustic standards apply to commercial partition walls?
We construct metal stud partition systems specified to meet Building Regulations Approved Document E and BS EN ISO 140-3 sound reduction benchmarks, incorporating dense acoustic plasterboards, twin stud frames, and acoustic mineral wool insulation to achieve ratings from 45dB to over 55dB.
