R factor for insulation

R factor for insulation

Our sales staff has been supplying wholesalers, contractors, and homeowners for many years. R -value is a measurement of thermal resistance and measures the ability of heat to transfer from one side of an object to another. As a benchmark, one inch of solid wood has an R -value of 1. In comparison, an inch of blown fiberglass insulation has an R -value of 3. The R -value depends on the type of insulation , its thickness, and its density. When calculating the R -value of a multilayered installation, add the R -values of the individual layers.


The practical implication of this is that one could double the R -value of insulation installed between framing members and realize substantially less than a percent reduction in heat loss. R -value measures how well certain building insulation materials can resist heat. The higher the R -value, the greater the insulation performance. Adding insulation to your attic, basement or crawlspace is one the best ways to improve energy efficiency in your home.


With over a decade of experience in insulation , heating, ventilation and air conditioning service and sales, you can count on R Factor , Inc. R Factor leads the competition in spray foam installation and has done so for years. Generally it is listed on an insulation material’s label.


R factor for insulation

Wall Insulation : While wall insulation is limited by the width of the studs, different materials provide higher or lower R -values. The R factor stands for thermal resistance. Fiberglass batts for standard 2×walls are now available in low, medium, and high density products that range from R -to R -15. You will need a higher R -value of insulation if you live in the Northeast than if you live in Southern California. We provide unique and creative solutions to those looking for spray foam insulation products.

Our areas of services are as wide as our coverage area, we will provide our services and solutions throughout most of the great lakes region. All values assigned to insulation are based on specific thicknesses and are usually noted on the packaging. So, what exactly is insulation R -value and how does it affect performance?


Here’s what you should know. What Is Insulation R -value? Simply put, the R in insulation R -value indicates resistance—this is used as the basic.


It does this better than traditional types of insulation. R means resistance to heat flow. Compare insulation R -values before you buy. There are other factors to consider. The amount of insulation you need depends mainly on the climate you live in.


Insulation R values of various materials: This article provides a Table of Insulation Values and Properties for Various Insulation Materials useful in procedures to measure or calculate heat loss in a building, defines thermal terms like BTU and calorie, provides measures of heat transmission in materials, building insulation design data, and heat loss in a building. EcoTouch PINK Multi-Purpose, Small Project Unfaced Fiberglasss Insulation Roll in. The r -value of rockwool insulation and mineral wool insulation varies widely. It really depends on what form the wool is in.


Press or formed rolls and sheets will have a different thermal resistance than loose fill type insulation. Home Weatherize Insulation Insulation for New Home Construction Planning carefully for insulation in reduced utility bills and superior comfort during the life of the home. In this house, raised heel trusses accommodate R -insulation. Spray Foam Insulators specializes in the installation of Open Cell and Closed Cell SPF Insulation – including both petroleum and soy based products.


The choice for which to use can depend on a variety of factors. Open Cell SPF cells are not completely closed and air fills all of the “open” space inside the material. There are plenty of things to consider as you research insulation , and perhaps the biggest factor is the R -value. You can customize the map before you print!

Position your mouse over the map and use your mouse-wheel to zoom in or out. My question is, is this a good idea, what type of rigid board should I use? My understanding is that the polyiso foamboard does not hold up to any type of moisture but has a higher r factor per inch than the extruded but the extruded holds up better to moisture. CALCULATION OF K- FACTOR AND R -VALUE.


Heat is measured in British Thermal Units (BTUs). One BTU is the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit. Thermal conductivity (kfactor) is the measureof a material’s - ability to transfer heat. The Higher R -Value the Better The number next to the R is just a rating of its insulating power.


Department of Energy R -Value Recommendations for New and Existing Homes. Insulation Calculator To find out the minimum R -values for different areas of your home, simply select the state and county where you live. R -high-density insulation delivers more R -value than standard R -fiberglass insulation.
