Expert Advice & Guides for Composite Joists
Want to know more? Our in-house expert, Allan, gives his take on our composite joists, and we’ve selected some of our best guides to help you decide if this is the right choice for you.
A Word from Our Expert, Allan:
“When designing our composite battens, we focused on overcoming the main failures of timber. That’s why they have a higher load-bearing capacity and are engineered to resist rot, insects, and splinters.
Their greatest advantage, however, is their incredible resistance to moisture, which is the key to true, long-term durability. The question you should ask isn’t if your subframe will last, but how long you need it to. If you’re building a foundation that you don’t want to worry about for well over a decade, this is the right choice.”
