What is the difference between monofilament sheeting and debris netting?

Monofilament sheeting is a woven fabric that is largely windproof (70-90% wind reduction). It contains dust and provides weather protection but creates very high wind loads on the scaffold — requiring intensified ties. Debris netting is a coarser mesh that catches falling debris but allows wind through (50% wind reduction). It creates less additional wind load.

How much extra wind load does sheeting create?

Monofilament sheeting can increase the wind load on a scaffold by 300-400% compared to an unsheeted scaffold. This means the tie pattern must be intensified from the standard 4m × 4m to 2.5m × 2.5m (approximately double the ties). The scaffold may also need thicker standards or additional bracing. Always check with your scaffold designer before sheeting.

How is scaffold sheeting fixed?

Sheeting is typically fixed using bungee cords (elasticated ties with hooks) attached to the scaffold tubes at approximately 300mm centres around the perimeter of each sheet. Sheets are overlapped by 150-200mm and secured with additional bungees at the lap. The bottom edge must be securely fixed to prevent billowing. Cable ties should NOT be used as primary fixings.

When should I use sheeting vs netting?

Use monofilament sheeting when: weather protection is needed (painting, decorating), dust containment is required (demolition, abrasive blasting), or the client wants to hide the works. Use debris netting when: only debris catch is needed (general construction), wind load must be minimised, or the scaffold is in an exposed location.

Do I need to remove sheeting in high winds?

Sheeted scaffolds should be inspected before and after high winds. Most scaffold companies specify that sheeting should be partially released or removed if wind speeds exceed 17 m/s (38 mph). Some modern sheeting has wind-release panels that open in high winds. Never assume sheeting can withstand storm-force winds — the additional load could cause scaffold failure.

How We Calculate This

This calculator determines the sheeting or netting required for a scaffold face, including overlap allowances and additional tie requirements for wind loading.

Key considerations

Sheet area: Length × height + overlap allowance (10-15%)
Additional ties: 2.5m × 2.5m pattern for sheeted scaffolds
Fixings: Bungee cords at ~300mm centres
Wind: Sheeting increases wind load 3-4× — check scaffold design
