Introduction

Polyisocyanurate (or polyiso for short) is a type of foam insulation product that’s made with recycled plastic and other petrochemical products. This versatile material is applied to the outside walls of homes, commercial buildings, and industrial facilities. And because it requires less energy to produce, it comes with some pretty awesome benefits. So if you’re wondering what makes polyiso such a great green building material, read on!

the percentage of R-value

One of the most common ways to measure the quality of polyisocyanurate insulation is the R-value, which is the amount of thermal resistance in a material. The higher this number, the better.

To give you an idea, we’ll look at four different standards that are used for measuring R-value:

• RSI (Resistance to Static Pressure)
• M2 (Metric 2)
• M2K/W (Metric 2 Kilowatt Hours per Square Meter per Degree Celsius)

the percentage of compressive strength

Compressive strength is another important quality of polyisocyanurate. It’s important because it tells you how much weight your insulation can withstand. For example, if your insulation has a compressive strength of 30 psi, then it can withstand up to 30 pounds per square inch (psi) of force before breaking or rupturing.

To measure compressive strength, you’ll need a specific piece of equipment called a tensile tester that applies pressure in three different directions: vertical (up and down), lateral (left to right), and longitudinal (back and forth). The test results are then used to calculate the compressive strength using a formula called the “Cobb Method”.

The standard range for polyisocyanurate’s compressive strength is between 15 psi (polyiso foam board) up to 60 psi (polyiso rigid foam).

the percentage of resistance to heat transfer

The percentage of resistance to heat transfer is a measure of how well polyisocyanurate insulates against air leakage, as well as radiant heat. Quality polyisocyanurate has low resistance to air leakage, which means it will prevent your home from losing heat. Heat loss through poorly insulated walls and ceilings can lead to uncomfortable temperatures in your home, as well as increased energy costs.

When you purchase new household products (or work on your existing ones), always make sure they are high quality so that they offer you the best value possible. Choosing an inferior product will result in poor performance and wasted money over time!

the physical properties test

A physical properties test is a test of the physical properties of a material. There are many types of physical tests, including tensile strength, compressive strength and flexural strength. The purpose of these tests is to examine how much stress or force can be applied on a material before it breaks apart or goes out-of-shape. For example, if you had an item made by Polyisocyanurate that was supposed to withstand high amounts of pressure but it failed during an experiment then you may want to consider other options when purchasing products like this in the future

the percentage of water vapor permeance

The percentage of water vapor permeance is an important measure for insulation because it helps to determine the overall heat resistance of the material. It also plays a role in determining how comfortable or uncomfortable your home will feel, which is especially critical if you live somewhere very hot or humid. In fact, many people will choose polyisocyanurate over other options simply because it’s better at preventing moisture build-up in their homes and keeping them dryer during rainy seasons.

It’s important to know how to measure high quality polyisocyanurate.

While it’s important to know the different ways to measure what is good in polyisocyanurate, it’s even more important to know how to measure high quality polyisocyanurate.

Luckily, there are 5 ways that you can use when measuring high quality polyisocyanurate: 1) comparing the cost of your product with another manufacturer; 2) checking for any chemical reactions with other products when you’re making your own; 3) seeing if there’s any special equipment or technology needed in order for them to be able to complete their work successfully; 4) verifying whether or not they have insurance coverage (so if something were ever stolen from them or broken during transport); and 5) verifying whether or not they have references from past clients who were satisfied with their services (and asking those clients directly).
