Understanding Heat Flow

Never has a homeowner walked a model home and asked the salesperson about building science. New home shoppers expect that their new home automatically includes a living environment as comfortable as it is beautiful. Delivering on this expectation is building science. So what is building science?
Understanding Air Flow
As reported in the January 2005 issue of PB, building science is a systems approach to home building that considers relationships between a home's components and its environment. The goal of building science: to optimize occupant health, comfort and safety; maximize energy efficiency and structural durability and reduce builder and contractor callbacks.
Clearing the Air
Designing homes with HVAC systems that provide optimal indoor air quality can affect your bottom line as a builder as well as your future homeowner's health and quality of life.
Moisture Flow
Because of its association with health concerns, moisture flow — as it relates to mold and mildew growth — has been a popular topic among homeowners.

Insulation has Damp Downside
Modern construction standards produce wellinsulated, tightly sealed houses that are relatively easy to heat and cool. But a house that is tightly sealed can develop a problem a 40-year-old house is unlikely to have: high indoor humidity in winter.

ZERODRAFT® Insulating Air Sealants Play a Key Role in BASF Near-Zero Energy Home-Paterson, N.J
ZERODRAFT® single- and plural-component insulating air sealants are making a key contribution to the building envelope system of the BASF Near-Zero Energy Home-Paterson, N.J.

BREAKING NEWS: Building America Launches Field Test Comparing COMFORT FOAM® with Traditional Systems
The study will include an evaluation of the speed and ease of installation, multiple short-term energy monitoring tests and air leakage and flow characteristics testing using a blower door, duct blaster and flow hood, as per RESNET standards.

Insulation is Not Enough: You can’t build a comfortable, energy efficient home without an effective air barrier.
Builders are under increasing pressure to produce beautiful, durable, sustainable, energy efficient homes. And while most strive to achieve these goals, many fall short on the fourth goal - energy efficiency – despite insulation over Code and high-efficiency HVAC designs. Why?

Making Foam Pay: The dollars and sense of using the most efficient insulation and air barrier.
Homebuyers want a lowe cost of ownership over the long-term. One of the best ways for builders to provide customer satisfaction—and profit from it—is to use COMFORT FOAM® closed-cell, spray-applied polyurethane foam: the only fully-tested, proven combination insulation and air barrier.

Benefits and Applications of Closed-Cell (High Density) Spray Foam Insulation — Part 1
CC-SPF is a superior insulation material and it provides superior moisture control, being an air barrier, a water barrier and a vapor retarder. This is good news for builders, because moisture control is critical. Why is CC-SPF so useful?

Solving Problems with Closed-Cell (High Density) Spray Foam Insulation — Part 2
More and more builders are using an insulation material that offers dramatic solutions to building problems: closed-cell spray foam (CC-SPF).

The Typar® Weather Protection System shields your homes, maximizes your investment.
As the best-performing housewrap on the market, Typar acts as a primary line of defense against the elements to keep wall cavities dry during construction, providing superior water holdout. It also acts as a secondary line of defense after the siding is up—to keep damaging moisture out for many years to come.

Typar® HouseWrap offers the best balance of water holdout and MVT.
If you looked inside your walls, what would you see? Framing lumber. Insulation. OSB. Housewrap. But you might be surprised to find something that shouldn’t be there: moisture.
