Indoor Ceiling Barrier Netting – How to Order / Measure By admin | Published on December 2, 2019April 14, 2020 Ordering the correct size netting panel for proper coverage can be tricky. It’s critical to measure correctly, and consider any angles that may require extra netting. Yes it’s time to brush off that dusty book of knowledge from high-school geometry you thought you would never use in real life!Remember the Pythagorean Theorem? Of course you do! Ok here we go, keep your heads up class: Measuring for a ceiling pitch When ordering a panel of barrier net to be hung parallel to a pitched ceiling, one of the first questions you might ask is how the heck do I figure out the correct length for the pitched side? If the span is relatively short simply get up on a ladder and measure it – however for longer spans there is a better way. To avoid using a bunch of mathematical terms like hypotenuse and euclidean geometry refer to the letter coded diagram to the right. We need to find the length of the barrier netting represented by the letter c on the diagram, to do so we simply need to know the lengths of a and b. a² + b² = c² To find a take the length of the highest point (typically the peak of your ceiling) the net will be hung (x) and subtract the length of the lowest point (typically where your side wall meets the ceiling – the ‘Eave’) (y) – b is simply the distance between x and y. Now all you have to do is a little math and you’ll have the length of your barrier net, c. For example, say the highest point your barrier netting will be hung is 20′ (x) and the lowest point is 12′ (y) – your a value is x – y i.e. 20′ – 12′ = 8′. You’ll know your b value by measuring the distance between the x and y – in this example let’s say the distance is 15′. So if we know that a² + b² = c² then we know that 8² + 15² = c² in other words (8×8) + (15×15) = c² or 64 +225 = c² or 289 = c² – so to get c you just take the square root of 289 which is 17. In this example the length of your barrier net is 17′. Tip: For extreme barrier net sizes consider adding 6-12″ of extra size, which will make installation easier. For applications requiring an extremely taut appearance, order your netting exact or slightly shorter – just be prepared to use extension links to connect to your wall if it doesn’t reach!
