Everguard Chimney Insulation Mix is a ready mix, vermiculite based insulation material. This pour-down insulator is an alternative insulating method to using the blanket wrap. Ideal for tight relining jobs or when an uninsulated liner had already been installed.
With competitive price and timely delivery, Zhiang sincerely hope to be your supplier and partner.
Not only is it easy to work with, but also helps fill dangerous voids in masonry and strengthen chimney walls. It cures into a lightweight, semi hard mass. Moreover, this adds support to the chimney liner and forms a thermal barrier to keep flue gases warm.
This product adds performance to your chimney liner and is very durable. The mix eliminates moisture buildup between the liner and the chimney structure.
Simply prepare by gradually adding 4-7 gallons of water. The insulation is properly mixed if it holds together when squeezed in your hand. Additionally, no water should come out when squeezed. Pour the mix around the chimney liner, while shaking the liner slightly to let the mixture settle. Next, let it solidify. Cure time is 24-48 hours.
Insulation is a crucial component of any building, helping to regulate temperature, reduce energy consumption, and improve overall comfort. Insulation R value, in particular, is a critical factor in determining the effectiveness of insulation.
R value measures thermal resistance, indicating how well insulation can resist the flow of heat. Understanding and calculating R value is crucial for choosing the right insulation for your specific project and ensuring optimal performance.
In this blog post, we'll take a closer look at how to calculate insulation R value, as well as the different factors that can impact R-value and how to choose the right insulation for your needs.
Insulation R-value is a measure of thermal resistance, or how well a particular type of insulation can resist the flow of heat. The higher the R-value, the better the insulation performs at preventing heat transfer.
When selecting insulation, it's important to choose the right R value for your specific project. Factors to consider include the climate in your area, the type of building you have, and the specific areas where insulation is needed. For example, homes in colder climates may require insulation with a higher R-value to keep indoor temperatures warm and comfortable.
There are many different types of insulation available, including fiberglass batts, spray foam, and cellulose. Each type of insulation has a different R-value per inch of thickness, so it's important to understand how R-value varies between insulation types.
It's important to note that R value is just one factor to consider when choosing insulation. Other factors, such as the material's ability to resist moisture, air leaks, and fire, should also be taken into account.
Overall, understanding insulation R-value is crucial for selecting the right insulation for your specific needs and ensuring optimal thermal performance. In the next section, we'll take a closer look at how to calculate R-value.
Calculating R-value is a straightforward process that involves a simple formula:
R-value = thickness of insulation (inches) / thermal conductivity of insulation (BTU/(hrft^2°F))
Here's a step-by-step guide to calculating R-value:
For example, let's say you have fiberglass insulation that is 6 inches thick and has a thermal conductivity of 0.24 BTU/(hrft^2°F). Using the formula above, the R-value would be:
R value = 6 inches / 0.24 BTU/(hrft^2°F) = 25
In this case, the R-value of the insulation is 25.
It's important to note that R-value is additive, meaning that the R value of multiple layers of insulation can be added together to get the total R-value. For example, if you have two layers of insulation with R values of 15 and 10, the total R-value would be 25.
While calculating R-value is a straightforward process, it's important to ensure accuracy by using the correct thickness and thermal conductivity values for your specific insulation. Common mistakes to avoid include using the wrong units or using an average R-value for a type of insulation rather than the specific R value for the product you are using.
While calculating R-value is a simple process, there are several factors that can impact the accuracy and effectiveness of insulation R-value. Here are a few key factors to consider:
By taking these factors into account, you can ensure accurate R-value calculations and choose the right insulation for your specific needs to ensure optimal thermal performance. In the next section, we'll take a closer look at how to choose the right insulation.
When it comes to selecting the right insulation for your specific needs, there are several factors to consider in addition to R-value. Here are a few key considerations:
Overall, choosing the right insulation involves a careful consideration of several factors, including R-value, material, location, climate, and cost. By taking these factors into account, you can select the insulation that best meets your specific needs and ensures optimal thermal performance.
Dense pack cellulose insulation typically has a higher R-value than loose-fill cellulose insulation due to its denser installation. The R-value of dense pack cellulose insulation can vary depending on the thickness of the insulation and the specific product being used, but it generally ranges from R-3.2 to R-4.0 per inch of thickness.

The higher density of dense pack cellulose insulation allows it to fill gaps and cavities more effectively, reducing air leaks and improving thermal performance.
Proper installation is important to ensure that dense pack cellulose insulation achieves the desired R-value and provides optimal thermal resistance.
The R-value of spray foam insulation can vary depending on the specific product being used and the thickness of the insulation.
Closed-cell spray foam insulation typically has an R-value of R-6.0 to R-7.0 per inch of thickness, making it one of the highest R-value insulation options available.
Open-cell spray foam insulation typically has a slightly lower R-value, ranging from R-3.5 to R-4.0 per inch of thickness. However, open-cell spray foam insulation is often used in applications where sound insulation is also important, as it can provide superior sound attenuation compared to other types of insulation.
Proper installation is important to ensure that spray foam insulation achieves the desired R-value and provides optimal thermal performance. It's also important to consider the potential health and environmental impacts of spray foam insulation and consult with a professional to determine if it's the right insulation option for your specific needs.
The R-value of blown-in insulation can vary depending on the specific material being used, its density, and the thickness of the insulation.
Fiberglass blown-in insulation typically has an R-value of R-2.2 to R-2.7 per inch of thickness, while cellulose blown-in insulation typically has an R-value of R-3.2 to R-3.8 per inch of thickness.
The R-value of blown-in insulation can also be impacted by factors such as settling and compression over time, as well as the quality of installation. Proper installation is important to ensure that blown-in insulation achieves the desired R-value and provides optimal thermal performance.
When selecting blown-in insulation, it's important to choose the material and density that best meets your specific needs and budget. Consult with a professional to determine the recommended R-value and thickness for your specific location and insulation needs.
Fiberglass insulation typically has an R-value of R-2.2 to R-4.3 per inch of thickness, depending on the specific product being used. The higher the R-value, the more effective the insulation is at resisting the flow of heat.
Fiberglass insulation is available in both batt and blown-in forms, and can be used in a variety of applications, including walls, attics, and crawl spaces. Proper installation is important to ensure that fiberglass insulation achieves the desired R-value and provides optimal thermal performance.
When selecting fiberglass insulation, it's important to choose the R-value and thickness that best meets your specific needs and budget. Consult with a professional to determine the recommended R-value for your specific location and insulation needs.
Vermiculite Insulation Removal Everything You Need To Know
Vermiculite insulation typically has an R-value of R-2.0 to R-2.7 per inch of thickness, depending on the specific product being used. However, vermiculite insulation is no longer commonly used due to concerns about its potential to contain asbestos.
