' I ’HE opening and closing of doors subjects 
surrounding plaster to shocks. Not hard 
blows, it’s true. But never-ending vibrations, 
day after day, year after year. That is why 
cracks so frequently appear around much-used 
doors and windows. 
To avoid such unsightly defects, stronger con¬ 
struction is necessary. That is why the plaster in 
so many new homes is being made crack-proof with 
^nc-^urn 
METAL LATH 
"The steel heart of plaster” 
The steel strands of the lath reinforce the brittle 
plaster in every direction. 
To prevent cracks use Kno-Burn around windows and 
doors, in all corners, throughout bath rooms and on all 
ceilings under inhabited rooms. 
Fireproof construction of frame buildings is now possible. 
Incombustible plaster and Kno-Burn Metal Lath form a 
fire-resisting barrier that has been officially given a one-hour 
rating. Metal lath should also, for safety’s sake, be used 
over heating plants and at chimney breasts, under stairs and 
around stair wells. 
OCnoSum Ask Your Architect or Builder 
horv to make plaster crack-proof and frame 
homes fire safe with Kno-Burn. Or send for 
Home Building. You will find the sugges¬ 
tions practical and valuable. Free, of course.
