Vinyl Siding Preparation
When installing vinyl siding, preparation is a matter of insulating as well as smoothing the surface over which the vinyl panels will be installed. Though some vinyl siding products are backed with an insulating material, many are not, so it is extremely beneficial to fill in any cracks that may allow heat transfer with caulk. When dealing with a material that expands and contracts as much as vinyl, preparation for siding installation is obviously going to involve some very careful measurements. Protuberances like dryer vents and window and door trim should be put into place before the siding is installed, and care should be taken to allow a bit of wiggle room so the expansion and contraction of the panels doesn't cause the installed siding to bow or buckle.
