INSULATION AND VENTILATION
One of the most important parts of your home is not generally seen. Insulation has been installed in walls and ceilings according to manufacturer's recommendations. Check to make sure the insulation in the attic is kept dry. Watch for areas of moisture. Ventilation will prevent reduction of the insulating values due to moisture. Proper attic ventilation has been provided in your home and it is very important that the venting system function as designed. Proper ventilation helps to cool the attic during the summer and reduces condensation and ice dam accumulation in the winter. Vents should be cleaned occasionally and should never by painted shut or covered with insulation.
Settling or shrinkage may occur in time and may slightly reduce the effectiveness of the insulation. For this reason, allowances are normally made at the time of installation to achieve specified insulation value after a period of settlement. In the event you wish to work under the roof and you have blown insulation, be careful to avoid disturbing the insulation resulting in heat loss.
Wall and ceiling insulation is normally protected with a covering layer of vapor barrier material, to prevent water vapor from penetrating the insulation and wood framing. Avoid penetration of the vapor barrier as much as possible. Water vapor will eventually migrate through the outside walls.
