What Insulation Provides the Highest R-Value?

If you're searching for the best home insulation with the highest R-value, rigid foam is the ideal choice. With an R-value ranging from R-4 to R-6.5 per inch of thickness, it is perfect for insulating exterior walls, including basement walls. Rigid foam panels have the highest R-value per inch among all insulation types. The exact R-value of each type of insulation varies by brand and product, and insulation with higher R-values retains more heat than insulation with a lower R-value. Consulting a table of R-values for insulation can help you insulate your attic, walls, floors, and mezzanines appropriately for your particular climate.

Insulation installed between the uprights can reduce, but usually does not eliminate, heat losses due to air leaks through the building envelope. As a manufacturer of rigid foam insulation, Insulfoam offers a number of product options that help construction teams reduce their ongoing costs of insulating material and labor. Vacuum-insulated panels provide the highest R value of all the insulators available on the market. Inadequate insulation can cause comfort problems and increase utility costs, while achieving recommended insulation levels makes your home more comfortable and energy efficient. Insulators with a high R value tend to be more expensive, and some homes in certain climates don't need as much insulation as others.

Blanket-type insulation, often sold in units called “blocks” or “rolls”, is the type of insulation most commonly installed on unfinished walls, floors, and ceilings. Due to the degree of standardization in the construction industry, insulating blankets are often the easiest to install. In general, structural materials such as brick and wood are not intended to serve as primary insulation for homes, but they do provide some insulation. Old or poorly installed insulators will start to break down and release particles of themselves into the airflow of the house. We'll make recommendations based on your needs and budget, and we'll install the insulation you prefer quickly and affordably.

Installing a continuous layer of rigid foam insulation on the outer side of the wall covering will interrupt the formation of thermal bridges across the uprights and, at the same time, reduce the rate of air leaks. Knowing the R-values for insulation throughout your home tells you if you have enough insulation depending on where you live. The main function of such insulation is to make the thermal conductivity of the insulation that of trapped and stagnant air. Whether you know what type of insulation you want or are looking for personalized advice, the insulation experts at Mooney & Moses can help. Rigid foam or panel insulation is usually installed during the construction of residential buildings, including in basements, roofs, floors, foundations, and walls.
