In general, the color of insulation doesn't equal better performance over another color.
Properly working insulation should be a yellow, white, green or pink color depending on the manufacturer. Move the insulation on the basement ceiling around a little bit (just use a wooden spoon or other object to push it back and forth) to see if it has darkened.
Fiberglass gets discolored when it filters the air leaking from your house. Over the years, the air leaking from the house, carrying dust and other particulates and moisture, turns the fiberglass black. So wherever you see black fiberglass, dig down and look for where the air is leaking out.
House insulation: The most effective insulation
So having in mind that spray foam, fiberglass, and cellulose are the three mostly used insulation materials we made a comparison, and here are the results: Spray foam has by far the highest R-value, which is crucial for homes in extremely cold climates.
There are other types of insulation, but these are the most common. The best non-toxic insulation is either mineral wool or foam insulation inserts.
What is the pink fluffy stuff on the walls? The pink fluffy material is usually fiberglass insulation, commonly used for its safety and efficiency. It does not contain asbestos.
Breathable insulation materials allow for moisture vapour through their porous nature, reducing the risk of condensation buildup. The most popular breathable insulation materials on the market are blanket-style insulators like mineral wool, sheep wool, and fibreglass insulation.
Fibreglass insulation is the most effective for frigid climates; it can be applied to walls, lofts, and other areas where heat may escape. Adding insulation can reduce energy costs and maintain a comfortable residence throughout the winter.
Thermablok® Aerogel is a revolutionary advancement in thermal technology offering the thinnest insulation available to prevent thermal and cold bridging. Classed as a Super Insulation, Aerogel has the highest insulation value of any known material with the lowest thermal conductivity value of any solid (0.015W/mK).
Internal wall insulation is done by fitting rigid insulation boards to the wall, or by building a stud wall filled in with insulation material such as mineral wool fibre. Internal insulation: Is generally cheaper to install than external wall insulation.
Yellow insulation is often associated with cellulose or another type of fiberglass insulation. For cellulose, the yellow color may be a result of the type of recycled paper or additives used.
In general, the color of insulation doesn't equal better performance over another color. Whether it's pink, white, brown, or yellow—color doesn't influence dependability, reliability, or the products effectiveness.
Because of the high amount of air that can move through fiberglass however, trapped particles can be filtered out of the air including food sources for mold and mold spores themselves. Over time, given the right conditions, mold can grow in fiberglass.
Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.
White, Pastels & Light Neutrals
They reflect significant sunlight, thus keeping the house cool. Moreover, these shades fade less, so the need to repeat or retouch is decreased while giving the house a fresh and timeless appeal.
Pink insulation is an eco-friendly solution as the fibers don't contain any dangerous materials or toxic gases. It also helps reduce energy consumption by preventing heat transfer in summer and cold air from entering in winter. This means you can save more money on your energy bills while preserving the environment.
Spray Foam Insulation
Spray foam also offers a high R-value per inch, but while spray foam insulation has a lot of benefits, it is also one of the most expensive types of insulation. Professional installation is recommended to ensure that the foam is applied evenly, effectively, and safely.
For an attached garage – since these spaces are typically well insulated you'll want to make sure you've got at least an R‑value of R‑12, as well as ensure that the door itself has good resistance to cold temperatures.
Aerogel insulation offers the highest R-value of any insulating material at less weight and thickness—ideal for construction, refineries, pipelines, and thin-gap thermal barriers. Browse our superior selection of superinsulating aerogel blankets below.
Foam Board or Rigid Foam
They provide good thermal resistance (up to 2 times greater than most other insulating materials of the same thickness), and reduce heat conduction through structural elements, like wood and steel studs.
Studies conducted by the Department of Energy's Oak Ridge National Laboratories show that as outside temperatures drop, the R-value of fiberglass insulation decreases.
Fiberglass batt is considered to be the best insulation for attics. Compared to other insulation materials, it is the cheapest and easiest to install. Fiberglass batt is also incredibly energy efficient, as it helps to slow the spread of hot and cold air.
Fiberglass. Fiberglass consists of extremely fine glass fibers and is one of the most ubiquitous insulation materials. It's commonly used in many different forms of insulation: blanket (batts and rolls), loose-fill, and is also available as rigid boards and duct insulation.
