Supplied as a 7m wide x 15m long roll, (105 square metres per roll), weighing around 30Kg. The shrink wrap sheeting is generally folded down on to a roll that is 1.8m long for transport. Shrink wrap for scaffolds is generally supplied in white but your supplier may be able to provide a scaffold shrink wrap in clear if you require. Although a 7 metre wide shrink wrap film has become the most common size for scaffolds, you may see a 12 metre wide scaffold shrink wrap film offered by some suppliers. Whilst a 12 metre wide shrink wrap can be useful for some applications (such as temporary roofs) the extra roll weight (nearly 55Kg) makes it more awkward to handle on site and it may not be as easy to shrink as tightly as a 7 metre wide wrap.
Flame retardant shrink wrap has become the standard for scaffold sheeting applications. Your sheeting should be accredited flame retardant to EN13501 as standard but some construction sites will require that any temporary protection materials are certified flame retardant to the more extensive LPS1207 and LPS1215 flame retardant standard. Using a shrink wrap film that is not flame retardant to the requirements laid down by a construction site might lead to the insurance cover being invalid in the event of a fire.
The shrink wrap sheeting is the most important element of a shrink wrap encapsulation and containment project and so it is important to get it ‘right’. The challenge when buying shrink wrap film is that different brands look almost identical when they are folded on the roll; you will only notice the difference when you are using it on the job and by that time it is too late to change. Supplier’s only publish the best pictures of shrink wrapped buildings on their website! Even the worst film will be OK if installed on a calm day and may even look pretty good immediately after installation. However, the real test of a scaffold wrap film is what the encapsulation looks like in 1 or 2 months and that is when the quality makes a difference.
Unfortunately, the only way to be sure you are buying the right product is to do your homework – read the supplier’s website, ignore the bland sales messages and self promotion and choose a supplier who presents and unbiased view of their products.

How To Order Shrink Wrap Rolls
Most suppliers will offer a discount on shrink wrap film at the pallet quantity. For a 7 x 15m roll which weighs around 32Kg, the pallet quantity will be around 30 rolls.
Try and order sufficient materials to complete the job. Although there is theoretically 105 square metres of shrink wrap sheeting on every roll, you should budget for getting around 90 square metes of sheeting after allowing for overlaps and offcuts.
The size and weight of shrink wrap rolls means that they are generally shipped on a wooden pallet. This is great for delivering orders weighing up to 1000Kg but can be expensive for smaller orders. If you require just 1 or 2 rolls ask your supplier if they can deliver them via a courier as this will save you money on your delivery.
