Benefits of continuous Insulation

When it comes to the construction of a building, so may factors come into play to ensure that the quality of the structure is at a premium. From the foundation upwards, your builder needs to be aware every step of the way to avoid mistakes or simple misunderstandings that can be costly later on. In this article, we discuss the benefits of continuous insulation, what this means and what are our products of choice when it comes to insulating your walls.

A building separates environments. It creates an outside and an inside and in order to function properly, certain conditions must be met. These conditions include such factors as controlling heat flow, airflow, and water vapor flow, controlling light, noise and pests and to provide strength and rigidity and durability, to name a few (1). In order to provide a durable enclosure, wall assemblies must contain these four control layers as overlays to the structure: a water control layer, an air control layer, a vapor control layer and a thermal control layer (1).

We will not get into the details of these control layers at present, but feel free to research for your own interest by using the sources cited at the bottom of the article as a good start. What you need to gain from knowing this, is that one is providing a structurally sound building when one adheres to these conditions. One method of adhering to these conditions is to use continuous insulation.

Continuous insulation is when no single gaps or flaws are present in a building’s protection (2). The reason one would rather have continuous insulation simply stems from the notion that it doesn’t matter how good the insulation you use on your building is if there is an easy means for the energy to escape. For a builder to keep in mind, this means that a continuous layer of insulation, such as a rigid foam, expanded polystyrene, extruded polystyrene or polyisocyanurate needs to be applied even over the studs, in order for it to be deemed as ‘continuous insulation’ (2).

The original method of applying your typical Batts therefore would not be deemed as continuous as the segmented nature of the product would allow for energy to escape. This new and improved way of thinking has many positive benefits, not only on our pocket but for our health as well.

Dow Chemical states that by using their insulation products you can reduce the potential for condensation within the wall, as the dew point is located outside the wall cavity rather than inside, when one uses the continuous insulation technique. It is also leading to new, improved and somewhat cheaper building practices, as the use of continuous insulation is subtly changing the materials used in retrofits and building construction. All in all, it is a great technique to apply to a new building, and when you are considering renovations, it is a great idea to retrofit a wall with continuous insulation from now on.

What continuous insulation to use?

There are many types of continuous insulation that you can use. Rigid foam, expanded polystyrene, extruded polystyrene, polyisocyanurate and many more brands of products that compete with one another to sell you what they believe to be best that money can buy.

We believe that a Zip-system R board delivers above and beyond what they promise, and compared to standard foam sheeting, you are saving time and money on installation and protection. By combining both air and moisture protection into one sheath that is easy to install, the zip-system R board delivers on the factors that we discussed before when considering what a building is. The conditions that needed to be met in order to provide a structurally sound building included the four control layers; a water control layer, an air control layer, a vapor control layer and a thermal control layer.

All insulation, simply put is a thermal control layer. As we now understand, any continuous insulation is a better solution to thermal control than a typical insulation technique as the absence of gaps decreases the amount of energy lost. A zip-system R board which combines air and moisture protection also ticks off the remaining control layers of water control, vapor control and air control.

This revolutionary new approach uses cutting edge manufacturing that targeted the issues that builders were finding on the job site. By listening and talking to the people who actually use the product and creating with them a product that met the demands of today’s need for perfection, scientists were able to develop a system that was quick and easy to install and tackled many factors in one easy to use product.

So when it comes to building a home, or reconstructing part of a building, be a part of the revolution and make sure that you are complying to building codes and  using continuous insulation in order to keep your home cleaner and healthier. Know that the installation times of continuous installation are quicker and that the way we are moving forward with this technique is pushing other dated techniques of house building forward as well, bringing us into a more streamlined and economic future. The Zip-system R board has been praised by thousands of builders and building companies for its ease of installation and integrated air and water resistant barriers.
