The wind rating is an important factor when constructing a building. It is a classification that will affect the building materials and structure directly. Various parameters (e.g. geographic region, shielding, topography and terrain) need to be considered in order to calculate the correct wind rating. In other words, the wind rating can be different even they are in the same region.
Generally speaking, wind ratings from lowest to highest are N1—>N2—>N3—>N4—>C1—>C2—>C3—>C4. iBuild’s standard inclusion covers wind rating of N3 across all of our products. Optional upgrade to C4 is available.
