Cardboard Lumber

Saw this in Facebook, could be some scary stuff to deal with in a home, imagine it's flammability rating and how fast it could fail, obviously from a cost standpoint but why?

I'm all for recycling but this is a little too far.

I can see it's uses in packaging, but no way for building.  I mean, how would one screw anything into these?  I understand the physics behind it, I seen several tests on the concept. 

Glue? I've bought some stuff online that has some pretty rigid corner guards but why would you maker it s cardboard lumber without intentions of building material?

40+ foot long floor joists made with OBS was first thought to be crazy too...

NIST has some awesome videos on OSB I-Beams v legacy style construction it is amazing how fast the floors built with them ibeams fail.

i agree not saying they are good.... or better...... but they are in use....

It's really scary how modern houses are made, trusses are held together by gusset plates which only penetrate 1/4" into the wood, under heat these plates peal and cause the roof to fail very quickly. Sad to say if we know a roof is a truss roof your house is probably going to burn down because it becomes unsafe to operate in.

in this bigger better faster world we sure take things for granted. When they build the house I own now circa 1900ish, they built it to last, would cost a small fortune more than normal to build it the same way today......

Yea try and take an axe through a lathe and plaster wall then take an axe through some gypsum board. Them houses built after world war 2 were built like battleships, when I went through my building construction courses for my fire fighter certification it really opens your eyes up in terms of home construction and most people take for granted what the roof over your head is really made of. Problem with all these new materials is the glue used in them is highly flammable, glue heats up and melts, product falls apart, structure fails... There you go
