Detail and Design ULTRAJoist to significantly reduce your project build time

ULTRAJoist - A strong lightweight floor system Engineered for Mid-Rise (6 storey) Construction:

How to Create a 40ft long 2x10 Structurally Finger Joined ULTRAJoist:.

CNC Machined

Engineered solid sawn lumber by structurally finger joining high quality pieces of lumber and then planing the engineered joist to precise dimensions which virtually eliminates shrinkage.

Ease of rough-ins by designing and detailing services using CNC machines fed directly from CAD files

ULTRAjoist lumber is kiln dried to 14% moisture content.  Then treatment for flame retardant and moisture repellant is applied using a double vacuum, low pressure treatment process that treats all six (6) faces of each piece of lumber at once.
