SOLUTIONS GET GREAT SAVINGS FROM ENERGY COST REDUCTION AIR SEALING MEASURES BEST RETURN ON INVESTMENT! ALWAYS SEAL CEILING 1 ST IT HAS THE MOST HOLES GREATEST OPPORTUNITIES
MOST LIKELY TO IMPROVE COMFORT COMPLETE AIR SEALING ENVELOPE BECAUSE Premier Building Scientist, JOSEPH LSTIBUREK When answering question: WHY BUILD A TIGHT HOUSE? Before you can control air you must enclose air. Over ventilating during cold weather leads to comfort problems. Builder s Guide To Cold Climates Chapter 12 2012
MOST LIKELY TO IMPROVE COMFORT COMPLETE AIR SEALING ENVELOPE BECAUSE WINTER TIME STACK EFFECT BIGGEST AIR LEAK DRIVER RETARD STACK EFFECT - CAP CEILING WHEN AIR SEALING COMPLETE IMMEDIATELY RESOLVES VIRTUALLY ALL UNEVEN HEATING/COOLING CONCERNS
WHEN A TIGHT HOUSE FEELS WARM/COZY? NO NEED TO UPGRADE EXISTING HVAC DESIGN? AIR SEALING WORK COST-EFFECTIVE WHEN COMPARED WITH HVAC WORK REPAIR/REPLACE UNDESIGNED OR DESIGNED DUCTWORK ZONE SPACE CONDITIONING
DOWNSIDE TO HVAC 1 ST UNLIKELY HVAC REDESIGN WILL WORK WELL CREATE A NEW UNSEEN ISSUE MAKE EXISTING ISSUE WORSE

A NOTE ABOUT CASE STUDIES THIS SHOULD GO WITHOUT SAYING. IF YOU RECOGNIZE A CASE, PLEASE KEEP IT TO YOURSELF.
I TRUST INSTALLERS WANT TO SOLVE COMFORT ISSUES! Verify SUCCESSFUL Efforts with PERFORMANCE TEST STANDARDS KNOW HOLES SEALED BETWEEN LIVING SPACE AND UNCONDITIONED ATTICS! OUR DESIGNED SOLUTIONS ARE DATA DRIVEN WE GENERATE DATA AND ANALYZE IT AGAINST LONG STANDING TESTING STANDARDS

CAUSE OF MOLDY ATTICS MUST CONTROL SOURCES OF MOISTURE CONTROLLING VAPOR LEAKAGE TRUMPS ATTIC VENTILATION NEVER JUST ADD VENTS AS SOLUTION! IT LL EITHER MAKE AN EXISTING ISSUE WORSE CREATE A CONDITION WHERE IT DIDN T EXIST COLD ATTIC AIR CAN T HOLD THE AMOUNT OF VAPOR FOUND IN LEAKING LIVING SPACE AIR! REALLY? PROVE IT!

HOW MUCH VAPOR CAN AIR HOLD?
RH LOWERS WHEN AIR WARMS BEAKERS AIR S CAPACITY TO HOLD VAPOR EACH BEAKER SIZE DOUBLES RH DROPS BY HALF EACH 20F WARMER TEMP. 50% 25% 12.5%
RH RAISES WHEN AIR COOLS VAPOR ADDED TO INDOOR AIR BATHE BREATHE COOK AND LAUNDER RH RAISES UNTIL SATURATED LEAKING AIR COOLS IN ATTIC AND ROOF DECK DAMP EXCESS VAPOR CONDENSES
