Insulation and House Wrap

WSR Construction, Inc offers:

  • House wrap installation

  • House insulation

There are several advantages to insulating your home:

  • Proper insulation reduces energy costs
  • A well-insulated structure does not gain or lose heat as quickly as a poorly-insulated one, so it is easier to maintain a comfortable temperature
  • The retention of conditioned air lowers the demand on the heating and cooling systems. This reduces operating costs and extends the life of the system

Purpose of House wrap
House wrap serves as a dual-purpose weather barrier. It not only minimizes the flow of air in and out of a house, but also stops liquid water and acts as a drainage plane. The unique characteristic of house wrap is that it allows water vapor to pass through it while blocking liquid water. This permits moist humid air to escape from the inside of the home, while preventing outside liquid water (rain) from entering the home.

When Should House wrap Be Used?
Almost all exterior finishes allow at least some water penetration. If this water continually soaks the wall sheathing and framing members, problems such as dry rot and mold growth could occur. House wrap stops water that passes through the siding and allows it to drain away from the structural members. In humid climates with heavy rainfall, house wrap is recommended to prevent water damage to the framing. Use in dryer climates may not be as critical, since materials are allowed to adequately dry, although house wrap also prevents air movement through the wall cavity, which is beneficial for insulating purposes.

Why Insulate Your House?
Heating and cooling account for 50 to 70% of the energy used in the average American home. Inadequate insulation and air leakage are leading causes of energy waste in most homes.

Insulation:

  • saves money and our nation’s limited energy resources
  • makes your house more comfortable by helping to maintain a uniform temperature throughout the house
  • makes walls, ceilings, and floors warmer in the winter and cooler in the summer

What Is an R-Value?
Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness, and its density. In calculating the R-value of a multi-layered installation, the R-values of the individual layers are added.
