Horizontal Siding Seams

Joint covers are primed on the outside for easy painting and coated on the inside with an epoxy backer to inhibit.

Horizontal siding seams.

The seam allows the vinyl to expand and contract along with fluctuations in temperature. If horizontal siding is used a j channel or starter strip must be used. Use j channel to receive vertical siding. This prevents the siding panel from cracking in excessive heat or cold.

If you use a pressure washer start by ensuring that the stream is at eye level and pointed straight at the siding not at an angle. A wraparound lower lip hooks the siding and requires one nail to hold it in place. A seam is where two siding panels meet. They function as a joint much the same ways joints in concrete function.

The siding expands and contracts with temperature and humidity. While wainscot is traditionally run in a vertical pattern in modern designs we see corrugated metals often run horizontally. If starter strip is used it is necessary to provide at least 3 8 9 5mm clearance for proper engagement of the siding. The joint covers protect the butt joint where two siding planks meet and provide an expansion joint to help prevent siding buckling.

This type of wainscot is best combined with a warm material like a natural wood that contrasts well with the cool colors of natural steel. Since leaks can happen just as easily during the cleaning process as during a rainstorm horizontal siding requires a careful cleaning regimen so that you do not get water behind the siding. It needs to move and breathe.
