The Vinyl Siding Institute has certified around 1,400 products related to vinyl siding. The program puts items through rigorous testing and twice a year performs unannounced inspections of manufacturing plants. KP Building has almost a hundred vinyl products and numerous colors certified by the Vinyl Siding Institute (VSI). The high number of certified KP Building products stands as evidence of the manufacturer's reliability.
KP Building's vinyl log siding
You cannot get a vinyl log siding certified by VSI, so you'll have to perform your own research to locate a superior product. You might begin by considering a manufacturer that has other certified products. KP Building has many certified products and constructs vinyl log siding using several proprietary technologies:
- Ultra-Vinyl UV™ technology for weatherability and color retention
- Perform-Guard™ to repel insects from foam. The product is non-toxic and contains no chemicals related to ozone depletion
- LineLock™ panel locking system for greater wall stability
Vinyl log siding from KP Building has several other compelling features:
- Color-coordinated J channels, outside corner posts and undersill trims are available
- Panels are .046" thick, 10 percent thicker than regular vinyl siding and will not dent, crack, or split
- Limited lifetime-guaranteed panel
Recommended Improvements
The KP Building website does include a page on sustainability, but the site relates only the facts about vinyl as a product and does not point to any initiatives, rankings, or recognitions specific to KP Building. Some companies make a point to recycle all of their scrap produced in the manufacturing process so that they contribute virtually nothing to the landfill.
However, the solid construction and longevity of a KP Building product means that their vinyl products can help you save on energy costs and last for generations.
