ATTIC INSuLATION & VENTILATION PRO’S GEORGE ZENTZ • LICENSED BUILDER • INSURED • SINCE 1984 ATTIC INSuLATION & VENTILATION PRO’S GEORGE ZENTZ • LICENSED BUILDER • INSURED • SINCE 1984 Attic ventilation is an important, yet often neglected, issue affecting our home’s preservation. The building codes passed regarding attic ventilation are rarely enforced and often ignored. Nearly all homes in our area, both old and new, suffer from the effects of poor attic ventilation. In the summer, attic temperatures can soar beyond 160 degrees Fahrenheit. This heat broils the living space in your home and literally bakes the life out of your shingles. In fact, shingle warranties are void without adequate intake and exhaust venting. The cold, winter weather creates condensation in your attic which leads to mold and trapped heat will create ice dams. A properly balanced system of both soffit intake venting in the eaves and exhaust venting on the roof will cycle air through the attic to keep it cooler in the summer and drier in the winter. This will extend the life of your shingles, reduce your air conditioning expense, improve your family’s comfort and help prevent attic mold and ice dams. Unfortunately, most homes fall far short of the minimum amount of intake and exhaust venting that our attics require. Common problems include: little or no soffit venting, inadequate ridge venting, soffit or ridge venting that was installed improperly and soffit venting that is blocked by insulation. We can correct these problems by installing additional soffit venting, an attic fan or perhaps insulation baffles to channel the air from the soffit vents, past the insulation, and into the attic. Our attic fan will automatically draw the super- heated air out of your attic in the summer, pulling cool air in through the soffit vents, reducing your attic temperatures by up to 50 degrees Fahrenheit. During the winter months, the automatic humidistat will control the fan to keep your attic dry. Premium quality, energy efficient, thermally protected motor, quiet, ten year manufacturer’s warranty, available in black, brown and gray. Insulation baffles create a channel for the air entering your soffit vents to get past the insulation and into your attic cavity. Most homes have few, if any, baffles and they are often installed improperly. Bathroom exhaust fans must be vented out of the attic to prevent mold, rotten wood and ice dams. The preferred method is to install a combo vent with a built-in damper that prevents back drafts. WE’RE THE ONES TO CALL WHEN SECOND BEST JUST WON’T DO! Please call for an evaluation of your attic...(586) 997-4000 Copyright 2007 George Zentz We all know that energy costs are skyrocketing with no end in sight. The cost of natural gas for winter heating nearly tripled from January, 2000 to January, 2006 and the cost of air conditioning continues to climb as well. The ceiling in your home is the number one source of winter heat loss and summer heat gain. The good news is, upgrading your attic insulation to reduce your energy costs is comparatively inexpensive and will also minimize ice damming, reduce your risk of attic mold infestation, improve your comfort and increase your property value. Virtually all older homes fall far short of today’s standards and, surprisingly, even new homes in Michigan fail to meet of the Department of Energy’s minimum recommendation of R-49 for attic insulation. In fact, most new homes have only R-30 fiberglass insulation with an effective R-value of less than R-20 in the winter! Why should you hire the Attic Insulation & Ventilation Pro’s? I have been a contractor for over twenty years and have satisfied thousands of homeowners. I’ve accomplished this by being honest, knowledgeable, timely and competitive. I use only the highest quality materials and never sacrifice quality for profit. Many homeowners are concerned about reports of unscrupulous contractors who actually install far less insulation than quoted. We always install at least the amount quoted, and I personally guarantee it! I am state licensed and insured to protect you, the homeowner. We’ll do the most thorough job, treat your home with respect and clean up properly. This is why we can say, “We’re the ones to call when second best just won’t do!” Oak Ridge National laboratories found that as the temperature drops, the effective R-value of fiberglass plummets while the effective R-value of cellulose actually increases.

THE HIGHER THE “R” VALUE THE GREATER THE INSULATING POWER. We install premium grade cellulose insulation. Extensive, independent testing has repeatedly proven that cellulose outperforms all fiberglass products during both the winter heating and summer cooling seasons. Overwhelming evidence from internationally respected laboratories such as Oak Ridge National Laboratory, Brookhaven National Laboratory, University of Colorado School of Architecture, Cornell University, University of Illinois and even the National Research Council of Canada have concluded that cellulose is superior to fiberglass in energy conservation, preventing air infiltration, slowing the spread of fire and reducing convection. Convection is the movement of heat through the insulation, resulting in ice dams and attic mold. Fiberglass loses up to 40% of its R-value in the winter while cellulose actually gains R-value in the winter! R-value lost is heat lost into the attic, resulting in higher heating bills, attic mold and ice dams.
