Vinyl Siding Wind Load Test

Here s how my vinyl siding test works.

Vinyl siding wind load test.

Just walk back away from the home for 20 30 feet if possible so that you can c learly see the entire side of the house where the crack s occur. Like all building products vinyl siding insulated vinyl siding and polypropylene siding have been tested using astm d5206 to gather data on the maximum pressure to which the product is suited. Vinyl siding is a popular siding choice for many homeowners across the country but it can crack and tear during high winds. All vinyl siding must pass wind load testing.

All certified vinyl siding is tested for wind load resistance and must meet certain minimum requirements. According to fema vinyl siding should be able to withstand 110 mph winds in addition to heavy rains to be considered storm ready. Another component of the vsi certification program is the astm s standard test method for wind load resistance of rigid plastic siding d5206. Most vinyl siding has also been tested for higher wind pressures and can be used in locations with a higher basic wind speed greater building height more open exposure or some combination of those.

Restoration classic siding has been tested per astm 5206 standard test method for wind load resistance to withstand negative wind load pressures and their mph equivalents as shown in the chart below. At this distance i wouldn t be surprised if you can t see the cracks anymore. 5 1 this test method is a standard procedure for determining windload resistance of rigid plastic siding under specified uniform static pressure difference. If you re unsure of what those requirements are check with your local building inspection office.

Choose a product that meets or exceeds the minimum wind load requirements for your area. This typically is intended to represent the effects of wind loads on exterior building surfaces. Results from area averaged mean and peak pressure coefficients indicated that a very small portion of the total wind load is carried by the vinyl siding. Ask your contractor if the vinyl they use is up to those standards.

However pefs were found to be much higher when individual taps were considered.
