When you think about adding insulation to your home the image that usually comes to mind is long strips of fiberglass insulation in faced batts or unfaced rolls. Batts of faced fiberglass insulation is the standard material used to insulate wall and joist cavities during new construction, and improving the insulation in attics often involves laying a “blanket” of unfaced fiberglass rolls across the attic floor.

Keeping Bulk Water Away from Vulnerable Building Components
A water-resistive barrier (WRB) is a material installed between the sheathing (or studs if there is no sheathing) and the siding. It is designed to prevent water from reaching building components that could be damaged by moisture. Builders should assume that siding installations aren’t truly waterproof, and that some water will find its way through or around the siding (at least once in a while). Without a WRB, sheathing and other parts of the wall assembly would be much more susceptible to damage. Continue reading
When you are insulating two-by-four (2×4) and two-by-six (2×6) framed exterior walls and want to use fiberglass insulation, what thickness should you use?
This is a critical question. Adding too little insulation means a colder house. Adding too much insulation means insulation that isn’t properly doing its job, thus a colder house. Continue reading
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
Aerogel is a low density solid state material derived from gel in which the liquid component of the gel has been replaced with gas. The result is an extremely low density solid with several remarkable properties, most notably its effectiveness as thermal insulation. Continue reading
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
There are plenty of excellent insulation materials on the market today. Many of these have been around for quite some time. Each of these insulations have their own ups and downs. As a result, when deciding which insulation material you should use, you should be sure to be aware of which material would work the best in your situation. Considering differences like R-value, price, environmental impact, flammability, sound insulation and other factors, here are the 5 most common types of insulation materials:
