Preventing Mold During Construction
One of many things to take into account when building a house or any other facility is the growth of mold during the construction. Mold is everywhere, so it stands as huge and possible threat that can slow the construction and increase costs of replacing affected materials as well as costs of remediation. Depending on climate and location, some construction sites are more susceptible to moisture that later result in moldy buildings. The least expensive way to deal with the mold is the prevention and certain measures undertaken before and during the construction can go a long way.
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
Insulation materials run the gamut from bulky fiber materials such as fiberglass, rock and slag wool, cellulose, and natural fibers to rigid foam boards. Bulky materials resist conductive heat flow in a building cavity. Rigid foam boards trap air or another gas to resist conductive heat flow. Other less common materials included cementitious and phenolic foams, vermiculite, and perlite. Continue reading
What’s the Difference: Primers
Learn what the difference is between latex, oil-based and shellac-based primers and how to choose the right one for the job.
For most paint jobs, both inside and outside the house, latex paint is preferred. Latex emits fewer odors and VOCs than oil-based paint, and it cleans up much more easily. In one area, however, oil-based products still hold their own over latex: primers. With interior applications and exterior spot-priming, there’s another option: shellac-based primers. All three primers can be used under latex topcoats. Choose a primer based on the condition of the substrate to be primed and its location. Before you open the can, though, be sure to prep the surface you’ll be priming. No primer will perform its best if the surface hasn’t been thoroughly scraped, sanded, or otherwise readied for painting. Continue reading
What are Low-emitting Materials?
Low-emitting materials are products that do not release significant pollutants into the indoor environment. Volatile organic compounds (VOCs) are chemicals found in many common products and building materials that can escape into the air and cause illness and allergic reactions. These emissions are one of the contributors to the situation known as “sick building syndrome” (SBS) in which building occupants experience health and comfort effects. 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:

A Pacific Northwest organization has defined an environmentally sound structure as one that generates its own energy, captures and treats all of its water, operates efficiently, and is aesthetically pleasing. Many readers will recognize the movement as the Living Building Challenge, launched in 2006.
