PDF-ttic condensation during winter can decrease the effectiveness of insulation and over

And the same factors that cause attic condensation problems also cause ice build up on roof edges which can lead to ice damming If ice damming occurs it often results in snow melt water entering the home with the potential of causing significant wat. 20 1027200 1048830 1054860 1081860 1126920 1137390 1180200 1192470 1229340 1282710 O7 826440 864840 882600 896730 922290 947580 976770 1005900 1035120 1126920 1204380 O6 612540 672960 717120 717120 719850 750720 754770 754770 797670 873510 918030 O5 I X The Optimo range I I I I JI I Optimo straps and saddles II I XII Y I I I I W JI I I II I I I F X F W I I I Y JI F I I X I I I F RValue Thickness mm Width mm Length mm Ventilation for a healthier home F F W WI Y I Conditional Density Propagation for Visual Tracking.

SBCA.  has been the voice of the structural building components industry since 1983, providing educational programs and technical information, disseminating industry news, and facilitating networking opportunities for manufacturers of roof trusses, wall panels and floor trusses. . Folks, I just received a rather disturbing series of pictures of new construction currently going on in New Jersey.    Apparently these new-style wood trusses are commercially available and no longer use the metal "gusset plates" that we are all familiar with. This new breed of firefighter-killers is simply 2x4 Finger Jointed lumber (yeah, it's not even dimensional lumber) held together by little spots of glue where the webs meet the chords. Check out the attached pics... You also can see that these particular trusses are installed in townhouse-style occupied multiple dwellings. All that's holding them up is a 2x8 or TJI sill plate that's anchor bolted to the block sidewall.    I'm not an engineer, but it looks like it's actually the dead load and   live load from above that holds the house of cards together. My dad is a commercial sales manager at a large lumberyard. He is going to further investigate the manufacture and engineering of this product and I'll keep you advised of anything important to our operational safety.   If a standard gusset-plated truss will fail in less than five minutes of fire exposure, how long will these toothpicks stand up? How about the added weight of 2 or 3 firefighters with equipment trying to make a vent hole and removing some of the engineered dead load providing the stability to the system?  Just food for thought. This stuff's out there... It's just a matter of   time 'til it pops up around here. Many nationally recognized instructors are now recommending popping a decent-sized inspection hole in the ceiling immediately inside the point of entry and on each floor of any building with smoke or fire .
