Guideline Limitations
This installation guide is intended only for I-Series. The
person using these guidelines should already have a
general understanding of deck-building practices. Decks
must be built in accordance with all relevant bylaws and
building codes�
It is the responsibility of the installer to meet all code and
safety requirements, and to obtain all required building
permits. The deck and railing installer should determine
and implement appropriate installation techniques for
each installation situation. Fortress Building Products and
its distributors shall not be held liable for improper or
unsafe installations. These guidelines are designed to assist
you with I-Series installation and advise you on the unique
installation requirements for this product.
Note:
• Joist spacing for I-Series profiles can be up to 16"
[406.5mm] O.C. in most residential applications. Exceeding
this length can jeopardize the performance of your deck.
• Double joists should be used at all butt joins. Ensure that
hidden fasteners are installed within 1" [25.5mm] of the
end of the I-Series decking board�
• Breaker-boards running perpendicular to other decking
Boards should be used at butt joins to assist with
controlling the expansion and contraction of I-Series
decking. Top-fixed boards should be fastened at exactly
1-1/4" [31.75mm] from any edge of the board�
• Expansion gaps are needed at both ends. To allow for
the material to naturally expand and contract without
any issue�
