Compression Strength

Wherever you trust a wooden sill plate, you can trust the Joto-Vent System

Will it Crush?

With the Joto-Vent being installed between the concrete foundation and the sill plate, it supports the entire weight of the house. Some people may wonder "Will it crush?"

No, it will not crush. The vent is made of a composite material that consists of calcium carbonate, polyolefin resin and recycled plastics. It has an ultimate compression strength of over 56,000 pounds per lineal foot of Joto-Vent, and when you apply ICC-ES you can safely support 7,140 pounds per lineal foot of Joto-Vent. Wherever you trust a wooden sill plate, you can trust the Joto-Vent System.

Compression Test

A compression test has been conducted on the Joto-Vent as shown in the photographs below and the testing indicated the vent system was stronger than the sill plate.

The above photographs show no visible or measurable crushing of the Joto-Vent while the 4” x 6” Douglas Fir post is crushing into the Douglas Fir sill plate under load.
