What the Industry Has Become Accustomed to…

Fire retardant treated plywood, using pressure impregnated chemicals, has been around for decades and does a good job of mitigating flame spread, but has limitations in its use with multi-hour exterior load bearing wall assemblies that have become the new norm in today’s building codes. More recently, fire retardant OSB has come to market using spray application of magnesium oxide as a means of decreasing heat transmission, thus becoming an option in multi-hour wall assemblies, where historically fire retardant plywood has not.

Meet MagTech

The Obvious Choice for Contractors

MagTech is different and the resulting product is an extraordinarily high performing fire retardant OSB sheathing that offers a variety of assembly options not previously available with other fire retardant sheathings. MagTech™ provides protection against fire damage through the use of a magnesium oxide layer that significantly decreases flame and smoke spread. Ideal for load-bearing building applications, MagTech™ Fire Retardant OSB Sheathing can be used in the same way that traditional OSB is used but provides serious protection against fire damage and is a more environmentally friendly solution.
