Air Vapor Barriers

Today there are many choices for Air / Water Barriers for both commercial and residential applications. Each product offers different performance benefits which need to be weighed based on the goal of a particular project. One the low end there is your typical builders wrap. which is only providing a basic air barrier between the siding and exterior sheething. Over the years, as we have learned more about water management and code has required us to build homes tighter, it has become a science to deal with Water infiltration and Air Sealing. See some of the standard and innovative Air Barriers we supply and choose the one that best fit your projects goals.


BlueSkin VP 100 is one of the premium “peel and stick” self-adhering water resistant air barrier membrane’s on the market today. Henry BlueskinVP is a fully-adhered system that functions as a water resistant barrier but also stops uncontrolled air leakage.  The self sealing membrane significantly helps to reduce air leakage caused by nail penetration through during siding install.  With BlueSkin House wrap, meeting even the most stringent energy codes has become more manageable and cost effective for both contractors and homeowners alike.

BlueSkinVP can significantly reduce the air changes per hour and potentially save a home owner thousands of dollars over time.  BlueSkin is available in the following roll sizes:

48″ x 100′

12″ x 100′

9″ x 100′

6″ x 100′

4″ x 100′

In order to maximize the effectiveness of any BlueSkin installation, the following products are essential depending on the application:

BlueSkin WB Window Sill Flashing Tape- Zero Perm Tape available in 4″, 6″ or 9″ rolls by 50′ long

BlueSkin LVC Primer

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. Here at Sterritt Lumber, we trust the two most prominent manufacturers in the industry, Dow and Owens Corning to supply our loyal customers with the proper type of insulation.


The amount of energy you conserve will depend on several factors: your local climate; the size, shape, and construction of your house; the living habits of your family; the type and efficiency of the heating and cooling systems; and the fuel you use.

Heat flows naturally from a warmer to a cooler space. During the winter, heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements – wherever there is a difference in temperature. During the summer, heat moves from outdoors to the house interior. To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. Insulating ceilings, walls, and floors decreases the heating or cooling needed by providing proper resistance to the flow of heat.

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.

The effectiveness of an insulated ceiling, wall or floor depends on how and where the insulation is installed.

Insulation which is compressed will not give you its full rated R-value. This can happen if you add denser insulation on top of lighter insulation in an attic. It also happens if you place batts rated for one thickness into a thinner cavity, such as placing R-19 insulation rated for 6 1/4 inches into a 5 1/2 inch wall cavity.

Insulation placed between joists, rafters, and studs does not retard heat flow through those joists or studs. This heat flow is called thermal bridging. So, the overall R-value of a wall or ceiling will be somewhat different from the R-value of the insulation itself. That is why it is important that attic insulation cover the tops of the joists and that is also why we often recommend the use of insulative sheathing on walls. The short-circuiting through metal framing is much greater than that through wood-framed walls; sometimes the insulated metal wall’s overall R-value can be as low as half the insulation’s R-value.

Much of our Owens Corning insulation comes in the form of blankets that are in the form of batts or rolls. These are flexible products made from mineral fibers, including fiberglass or rock wool. They are available in widths suited to standard spacing of wall studs and attic or floor joists. They must be hand-cut and trimmed to fit wherever the joist spacing is non-standard (such as near windows, doors, or corners), or where there are obstructions in the walls (such as wires, electrical outlet boxes, or pipes). Batts can be installed by homeowners or professionals. They are available with or without vapor-retarder facings. Batts with a special flame-resistant facing are available in various widths for basement walls where the insulation will be left exposed.

Our DOW products take the form of rigid insulation. This is made from fibrous materials or plastic foams and is produced in board-like forms and molded pipe coverings. These provide full coverage with few heat loss paths and are often able to provide a greater R-value where space is limited. Rigid insulation is often used for foundations and as an insulative wall sheathing.

Whether your insulation needs are commercial or private, trust our professionals at Sterritt Lumber as well as the two most trusted names in the industry to fulfill them!
