A joist cap that works with double the protection.
Most might consider a deck to be durable to the elements with minimal protection required. After all, the framing in most cases is PT (pressure treated) lumber and the decking surface is either an exterior decking wood or composite. What can go wrong? Right?
Let’s start with the fact that it is an exterior assembly exposed to all seasonal elements. This process of exposure to temperature swings, moisture, sun and shade all create stresses in the framing and the decking materials. In the short term, this may seam of no consequence. Give it a few years and the affects may begin to show. Or will they?
Beware the hidden places of damage
Unfortunately they may not. It is the hidden problem that often creates the most damage. It’s the areas you don’t see to be concerned about. And that brings us to that small contact point between the top of the joist framing and the bottom of the deck board. Here, moisture will collect, rest and do it’s magic as it always does. Breakdown and destroy!
It’s in this hidden space where FrameVent® shines and eliminates the damaged minutes, hours, months and years. It’s a simple solution that assists in the removal of the #1 culprit, moisture! With a butyl tape seal within the FrameVent® bottom, the top of the joist is capped and sealed while the “finger” tops provide gaps for air flow moving moisture away from the deck bottom.
