Long-Length Premium Vinyl Siding

Thunder Bay now goes to even greater lengths to enhance the beauty of your home. Using 25' or 16' 8" lengths requires fewer panels, resulting in fewer visible seams and saves on installation time. Long-length panels are especially advantageous for homes whose surface area is exceptionally long. This long-length advantage, coupled with Thunder Bay's other unique features, make for a panel whose performance really measures up!



Thunder Bay’s 25’ length covers larger homes with less laps or smaller homes with no laps for a more attractive, virtually seamless appearance.
 
  Thunder Bay’s popular 16' 8" length installs as easily as standard siding, but with less laps for a smoother, more seamless appearance.

25' installation only:

 
Fewer pieces per square for quicker installation.
Nailing: Pin-nail the center nail slot on the panel. Then proceed with standard nailing requirements.

Spacing: Once the panel has been pin-nailed, the nail spacing will
remain the same as standard-length panels.
