Framing Your House (cont. p. 12)


Open-Web Truss
 

The “open-web” truss is another engineered product that comes in multiple, pre-manufactured lengths and widths. 

Open-web is a generic term to describe this type of product.

It features bottom and top 2x4 plates, which are linked to one another by precision-cut 2x4 pieces.

Spiked metal plates tie it all together to form a load-bearing truss.

Like the I-Joist, open-web trusses have advantages over the 2x4 board.

And further like the I-Joist, they are more expensive.

 

 

 

Open-web trusses provide excellent structural strength.


The have the ability to effectively span very long distances.


They have two other helpful advantages over 2x boards and some types of I-Joist.

 

 

 

The 3 ½ “ top plate provides a wide surface for nails, screws, and glue that will serve you well in the long run.


Properly done, the installation of your wood subfloor onto open-web trusses will virtually guarantee a squeak-proof finished floor.
