Energy Efficiency

Fortunately, building professionals have available to them a range of insulation products that keep heat in during the winter and heat out during the summer. These include three common rigid foam insulation types: polyisocyanurate (polyiso), extruded polystyrene (XPS) and expanded polystyrene (EPS).

If you are building, remodeling or simply thinking of swapping out existing insulation in those areas of your home that are accessible, you will want to keep reading.

In a space twice as large as his old 2,000-square-foot row house, his monthly heating bill is half as much — just over $200 in the coldest months. "Jeremy made me understand that, if you do it right, you will pay upfront," Alvarez says, "but it will pay off in the end."

Since the launch of the EnergySmart program, every De Young home has come standard with high-efficiency HVAC filters, low-VOC paints and formaldehyde-free insulation to ensure a healthy home air environment.

Stretch codes have emerged as a promising solution that jurisdictions can use to drive better energy performance in the built environment and set a long-term vision for efficiency stringency in buildings further into the future.

The following video shows how to install dense packed cellulose insulation and reduce the amount of dust, powerful, high pressure blowers are used to pack the cellulose in wall cavities.

The Polyisocyanurate Insulation Manufacturers Association (PIMA) is hosting a webinar today, December 12, 2017, at 2:00 PM EST entitled, “Harmonizing Fire Performance and Energy Efficiency in Exterior Wall Assemblies.”

The Federal Trade Commission has proposed amendments to the R-value Rule, which governs ratings for home insulation, as part of its systematic review of all current FTC rules and guides.

The building envelope provides barriers to heat/cold, air, water, light, and noise. From an energy efficiency standpoint, the barriers to temperature and air are the big ones—the idea is to “seal” the envelope from the outdoors just like that envelope carrying a letter in the mail.

Staycell ONE STEP 255 is a two-part, closed-cell, intumescent, spray polyurethane foam product used to insulate roof decks, ceilings, walls, siding or structural steel and to provide an integral air barrier / insulation / vapor retarder for building envelope assemblies.
