Rock-Wool Insulation: What It Is and Where to Use It

The importance of a well-insulated home can’t be overstated: Properly sized and installed insulation can reduce energy usage, keep you warmer in winter and cooler in summer, and save you money with lower energy bills. Rock wool insulation provides thermal and sound insulation and can be used as a firestop between floors.
For homeowners and builders alike, fiberglass insulation has been the insulation of choice for many decades. While fiberglass remains very popular, there’s a relatively new type of insulation that’s making headway—and headlines—in the insulation industry. It’s called rock-wool insulation. Continue reading

Top Five Green Building Mistakes

How to avoid the five most common errors builders make when it comes to energy, health, and resource efficiency.

While green building technology continues to improve and new green products continue to evolve, they’re only “lipstick on a pig” if the home isn’t also energy efficient, built to last, healthy, safe, and affordable to maintain. Continue reading

Easy Ways to Seal Air Leaks Around the House

A typical family spends about a third of its annual heating and cooling budget — roughly $350 — on air that leaks into or out of the house through unintended gaps and cracks. With the money you waste in just one year, you can plug many of those leaks yourself. It’s among the most cost-effective things you can do to conserve energy and increase comfort. Continue reading

Duct Insulation Primer

Insulation is applied to ductwork to enhance thermal performance and prevent condensation and dripping. Duct thermal performance needs enhancement since air transported through a supply duct is at a temperature different than that of the surroundings. Insulation reduces the rate of thermal loss to those surroundings. Without insulation, the air would need extra heating or cooling in order to arrive at the design supply air temperature. Continue reading

All About Lighting Controls

Use lighting controls to automatically turn lights on and off as needed, and save energy. Of course you can save energy by turning off lights when they’re not needed, but sometimes we forget or don’t notice that we’ve left them on.

The most common types of lighting controls include:
• Dimmers
• Motion, occupancy, and photosensors
• Timers
 

Before purchasing and using any lighting controls, it’s a good idea to understand basic lighting terms and principles. Also, it helps to explore your indoor and outdoor lighting design options if you haven’t already. This will help narrow your selection.
