About Installing Insulation Around Attic Vents

The goal of an Detroit, MI insulation project is to improve the overall energy efficiency of a house by stopping hot, conditioned air from escaping through ceilings and cool outside air from entering attics. It also helps to keep temperatures more consistent from floor to ceiling and reduces outside noise and condensation.

There are many different types of ENERGY STAR ® certified insulation available. The type you choose will depend on the kind of renovation project you are doing and your ability to do it yourself (DIY). There are varying degrees of skill required to install different kinds of ENERGY STAR insulated products, so make sure you understand what you are getting into before you start.

When insulating attics, a proper ventilation system is also critical to prevent heat loss through roofs and the potential for ice damming (snow that melts from a warm attic and then re-freezes at the gutters, damaging the roof). If you already have insulation in your attic, be sure to check that it’s properly ventilated and to ensure there are no baffles or other obstructions that may block natural flow of outdoor air.

How Humidity Affects Attic Insulation and Energy Efficiency

Houses with half storeys have one particular area of air leakage that needs to be addressed: through the ceiling joists adjacent to knee walls. This can be a difficult space to access and insulate, but it is possible to achieve good results. Strap a layer of polyethylene to the joists and attic deck, then insulate between the strapping and staple a continuous sheet of polyethylene to the attic floor.
