WELDWOOD is t PLYIVOOD plUS

Plywood is recognized cs the strongest known moterial per unit ol weight. Constructed of wood lominqe whose groins run qt right ongles with eoch other, plywood overcomes the noturol deficiencies oI lumber by eliminoting weokness ocross the grcin and reducing exponsion cnrd contrqction to cr minimum. IT WILL NOT SPLIT.

To it opply the some fundomentcrl engineering principles qs underlie the lqbricotion of huge wire ccbles from tiny wire stronds-the strength of the combined plies is greoter thqn the combined strength ol the sepcrote plies. Add to this principle the stcntling developments due to modem qdhesives crrd modern production mechqnics crrd it is eosy to understond why plywood is specified where strengtlr" lighuess cnd low instcllction costs crre required.

To these gucrlificctions, WELDWOOD now crdds unquclified stcrbility under cmy cnrd all conditions ol inetcrllction through the cpplicction oI chemiccrlly iaert, phenol-lonncldehyde (bakelite-tnpe) resin crs Gr binder between the plie* WELDWOOD is cbsolutely WATEBPROOF, vennin repellent crnd heat-resistqnt up to lhe chcrring point ol the wood.
