Fiberglass and cellulose fiber are the two most common attic insulation materials. Each yields an R-factor of roughly 3.5 per inch. Cellulose consists of ground-up newspaper material, which is then treated with fire-retardant chemicals. Fiberglass is made of billions of strands of extruded glass fibers packed into specifically sized batts. Some fiberglass batting now comes encased in perforated poly bags to help contain loose glass fibers and make handling and installation easier. Fiberglass also is available as a loose-fill or blown-in material.

While the price of fuel oil, gas, and electricity continues to rise, attic insulation is relatively inexpensive and remains one of your best energy-efficiency upgrade values.

The DuPont™ StormRoom™ is solidly anchored in concrete which allows it to resist wind uplift forces and gusts of up to 250 miles per hour. Independent impact tests show that DuPont™ StormRoom™ withstood repeated hits by building timbers fired at speeds equivalent to those experienced in Category 5 hurricanes and F5 tornados.

In addition to their remarkable strength, shelters made with DuPont™ StormRoom™ with Kevlar® are designed to integrate seamlessly with the rest of the house, functioning as regular rooms with available plumbing and electrical lines. And because Kevlar® has such low electrical conductivity, it does not interfere with cellular telephone reception.

Snow melting and refreezing on your roof causes expansion and contraction which can cause cracks and damage to the integrity of your roof. Constant melting and build up of ice can be caused by a combination of factors:

1. Heavy Snow, Impeded Runoff

2. Inadequate Insulation, Low R-Value, Not Enough Air Pockets

3. Inadequate Home & Attic Ventilation

4. Improperly Installed Bathroom Venting

5. Clogged Gutters, Allowing Faster Ice Dam Build-Up & Preventing Runoff

Removing snow from the roof is the most obvious line of defense, but it may not be enough, and it may cause more damage. Even a small amount of residual snow and the melting and refreezing cycle can damage composition shingles and decking, and leaks may not be immediately apparent, dripping into attics and walls for weeks or months without evidence inside the home. Raking, shoveling, chopping and other aggressive means of removing ice and snow can cause more damage to the roof and results in many falls and serious injuries to homeowners every year. If you have ice and snow build-up, do not get on your roof, and do not strike your roof with an instrument from the ground. This is a job best left to professionals with non-damaging heavy-duty steamers, expertise, training and safety equipment.

However, ice dam prevention starts inside the home. Even if you have a new home or newer insulation, there may be ventilation problems or inadequacies that a qualified inspector can identify, saving you money and the inconvenience of new or expanding damage, mold problems and major repairs later.
