Scaffolding Nets

What debris netting actually does

Debris netting is a knitted mesh screen fixed to the outside of a scaffold. It catches the small material that would otherwise fall or blow off the working deck: dust, mortar droppings, offcuts, packaging, insulation fragments. It also cuts wind at the working platform, reduces the amount of spray and dust reaching neighbouring properties, and screens the site from view.

On most urban jobs it is the difference between a scaffold you can work from and a scaffold the council or the client shuts down. Anything that lands on a footpath, a parked car or a neighbouring roof is your liability, and a roll of netting is a fraction of the cost of one claim.

Debris netting is not a safety net

This is the single most important distinction on this page. Debris netting contains falling material. It is not designed, tested or rated to arrest a falling person, and it must never be relied on for fall protection.

Personal fall-arrest safety nets are a separate product manufactured and tested to EN 1263-1, with defined mesh, energy absorption and border rope requirements. If your risk assessment calls for fall arrest, you need certified safety netting installed by a competent rigger — not debris netting. The two are often confused on site, and getting it wrong is a serious safety failure.

Wind load: the thing most people forget

Netting a scaffold changes it structurally. An open scaffold lets wind pass through; a netted scaffold catches it. The forces transferred into the ties, standards and the building facade go up substantially, and the effect increases with the density of the mesh.

• A scaffold that was designed as open must be re-checked before it is netted — extra ties are often needed.
• Fully sheeted scaffolds carry far higher loads again than netted ones; do not substitute one for the other without checking.
• Scaffold design in Europe follows EN 12811; in the UK, TG20 compliance sheets cover netted configurations.
• Never net a scaffold that is already at its tie limit, and never leave loose flapping sections — they act like a sail and concentrate load.

If you are unsure, ask your scaffold designer before ordering. It is a five-minute question that avoids a collapse.

Fixing it properly

• Fix along all four edges, not just the top. A net tied only at the top will flap, tear at the fixing points and stop containing anything.
• Use cable ties or bungee ties at roughly 300-500mm intervals along every edge and at each intermediate standard.
• Overlap adjacent rolls by at least 100mm and tie through both layers, so debris cannot escape at the seams.
• Tension it evenly. Over-tightening tears the mesh at the fixing points; under-tightening lets it billow and pull ties out.
• Inspect after every storm and after any lift adjustment. Repair or replace torn sections rather than tying them back.
• Remove from the top down as the scaffold comes down, never from the bottom up.

Choosing a colour

All four colours are the same mesh in the same roll size, so the choice is practical rather than technical. Green and blue are the European defaults and are what most contractors specify by habit. White is common on residential and heritage work where a lighter, less industrial appearance is wanted, and it shows dust and staining more quickly. Red is used where a job wants high visibility or where the netting doubles as site branding. Some clients and local authorities specify a colour in the permit conditions, so it is worth checking before you order a full pallet.

Frequently asked

How long does a roll last? UV-stabilised netting typically survives multiple projects if it is taken down carefully, folded rather than balled, and stored dry and out of sunlight between jobs. Netting that is left up permanently and never inspected degrades much faster.

Can it be reused? Yes, and most contractors do. Check the edges and fixing points before reuse — that is where tearing starts. Netting with more than isolated small tears should be retired.

Do I need a fire classification? On many sites, particularly where hot works are carried out or where the scaffold abuts an occupied building, the client or insurer will specify flame-retardant netting. Ask us for the technical data sheet with the mesh weight, UV rating and fire classification for the roll you are ordering, and check it against your site requirement before committing to a pallet.

Can I order mixed colours on one pallet? Yes. Tell us the split you need and we will quote it.
