Mass Timber Structures Are Better With Additional Applied Science

February 11, 2020 by Steve Conboy

Last year on a panel discussion in the Portland Business Journal, some great architects made a logical case for using lumber (and mass timber) as building materials for tall structures. They said, "producing/growing lumber and mass timber sequesters carbon and generates O2", which everyone now knows is very good for our environment and humankind.

Significant scientific and technological efforts are ongoing with the aim of meeting the demands for housing with renewable sustainable lumber from trees for building mass timber buildings even taller than the trees that the lumber comes from. More demanding standards for fire, mold and moisture protection are needed when organic lumber materials are used to build taller buildings because safety has to be our number one priority here in America. We still have much to learn about the key chemical component in tree barks that resists fire that lumber does not have. The bark on trees has tannin a polyphenol that complexes macromolecules and reduces oxidants and radicals. That oxidation in fire of these large molecules with fire retarding properties does not exist when bark is removed and trees turn into lumber. For this reason many are saying we need to add applied fire science to the lumber that goes into mass timber layups.

The referenced panel discussion may be failing to point out that most kinds of tree bark provide a natural form of protection against fire, which is stripped away and removed during timber processing and lumber milling, making lumber and mass timber vulnerable to fire, after cutting, debarking and milling operations.

Today there is a great need to provide lumber for mass timber with Class-A fire-protection before it is shipped for use during building construction projects so that treated wood, lumber and mass timber products will have robust Class-A FIRE protection against for the ages, above and beyond ASTM E119 char-based fire protection. Since these tall structures are subjected to weather and rain we also need to add accredited science to defend the lumber in these tall structures from mold and rot and over saturation.

For this reason and to meet to great need in the wood framed and mass timber building industry M-Fire invented and developed its patent-protected Class-A fire protection, certification and documentation technology to help the global wood-frame and mass timber building industry build safer, faster, better and more sustainable using Class-A fire-protected wood and mass timber building products.

M Fire Holdings has spent years in creating laboratory test results for its AAA protection that defends the lumber from fire, mold, and rot to support this great mass timber movement better where the safety of the workers and engineering values are a high priority by reducing risk of loss in the hopes of reducing risk premiums.

There are 4 key reasons to make all USA Mass Timber buildings Class A with Mold and Water Repellency Protection.
1. Reduce Smoke Development for evacuations during a fire event.
2. Reduce Flame Spread and the chance of Flash Over while you reduce risk and loss.
3. Defend the future interior air quality from Mold
4. Protect the engineering values from Rot caused by weather saturation.
