That's why building companies are developing products that have a lower environmental impact. This white paper reviews looks at some of the ways that exterior building products offer sustainable options for your home project.
The building enclosure or envelope consists of many components that must work together. The components include controls for thermal, air, water, and vapor barriers for heat, air and moisture management. This white paper takes a look at the importance of weather resistive barriers and how it manages moisture in a building's envelope.
Windows can be one of your home's most attractive features. Windows provide views, daylighting, ventilation, and heat from the sun in the winter. One often-overlooked aspect of windows is the operating type of window. This white paper defines a variety of operating types and helps you choose the best one for your home.
High permeability vs. low permeability within the housewrap category… what does it mean and how does it affect your building practices? The intent of this paper is to explain this property thoroughly so that a better understanding of this building science principle can be gained.
It is important to design wall systems that manage bulk water and moisture properly. Walls are typically designed for performance specific to the climate where they are located. A test-hut protocol was chosen to investigate the performance of typical wall systems under hot-humid climactic conditions.
DuPont™ Tyvek® ThermaWrap™ R5.0 significantly contributes to home energy savings and improves comfort in the home. Energy modeling was completed to simulate a reside/remodel project using a REM/Rate™ analysis, which is the standard software used for HERS ratings.
Everyone knows that solar and wind are renewable energy sources. But there's another renewable resource that's often overlooked: geothermal heating and cooling. This guide provides a general overview of geothermal technology and it’s applications in high performance homes.
Heating and cooling costs are a big part of household's budget. You can take control of those costs by using high-performance, energy-efficient windows in your home. This white paper reviews some of the key features to consider when selecting windows.
As homeowners and building professionals learn more about building science, they understand more about how to design and build homes for the ultimate in performance and comfort. This white paper, sponsored by Ply Gem, explores some of the building products that can improve the performance of the building envelope.
Every home – new or existing – can increase its energy efficiency with the installation of a blanket of continuous exterior insulation over the walls and studs, thus reducing thermal bridging. This white paper identifies thermal bridging and why continuous insulation is the best way to address it.
More and more homebuyers are looking for homes that perform well, in addition to providing a comfortable, engaging place to live. And homebuilders are rising to meet the demand. Green builders are incorporating energy, water and resource efficiency, improved indoor air quality and sustainable and locally sourced products into their projects.
Every home needs ventilation to exchange stale indoor air with fresh outdoor air. That’s due to moisture, mold, and chemicals from carpets, clothing, paint, cabinets and other common items. This guide includes everything you need to know about the air in your home and the benefits of proper ventilation.
weeHouses are built in a factory and shipped with everything essentially complete. The weeHouse can be placed anywhere accessible by truck. The weeHouse system is based on modern aesthetics; efficient use of space, intelligent adaptation of prefab building technology, and good environmental stewardship.
If your house is older than 20 years or so, it may be time to replace your windows. Sure, windows can last a lot longer and they may be a key part of a historic home's charm, but they could be costing you money and wasting energy. This white paper explores some of the options for selecting replacement windows for your home.
Most older homes don't have a tight building envelope. That means air flows through cracks and crevices in the home, making it difficult – and expensive – to heat and cool. However, the owner of a 12,000 square foot historic home in Rhode Island wanted to completely renovate the home and retrofit it with geothermal heating and cooling.
Unique in shape and design, BEST® range hoods enable you to express your individuality with a twist on the traditional. This catalog allows your imagination to run free and design the gathering space of your dreams where you can cultivate your culinary aspirations.
Unlike a natural gas leak or a fire, radio-active radon gas is completely invisible, odorless and tasteless. One in fifteen US homes have elevated radon levels and it can be found in every state. This white paper identifies some of the ways radon enters a home and what a homeowner can do to prevent and mitigate radon from their home.
The ultimate lifespan of steel roof and wall panels depends on the quality of the coating system that protects it. Inferior coatings will not protect the steel substrate from harsh elements, and will be susceptible to corrosion, chalking and color fading.
Millions of homeowners annually purchase asphalt shingle roofs that will only last 20 years at best. Fortunately, this is changing. Homeowners are discovering a far more permanent roofing solution - metal. Explore advantages and dispel some common myths about metal roofing.
Over the course of a year, a net-zero home will produce as much or more energy than it uses. The energy production typically comes from renewable energy sources, such as solar, wind and biomass. This white paper looks at some of the systems that builders are implementing to achieve net-zero status.
