It’s June, and depending on your climate, you are probably experiencing the joys of summer, including temperatures that can really put a strain on the air conditioner. We are all trying to find the best way to keep our conditioned air and the heat out! So let’s talk exterior sheathing. People are continually looking at different ways to increase their energy efficiency and decrease their energy costs. So what do they do? Replace windows and doors. Well that’s a great start, but what about all that space between your windows and doors? How much energy do you think is leaving through your walls every day? Parents are always after their kids to shut the door so we don’t let the heat or cool air out but in reality, you could be losing up to 33% of your heating and cooling through your walls each day.
So how do we fix this? Well, this is where PlastiSpan insulation saves the day. It is more cost effective and time effective to increase your R-Value above grade by going from the outside in then from the inside out. Make sure you check your local building code; see what they have for rules, requirements and restrictions. This will save you from problems later on.
*All insulation will be called PlastiSpan from here on, but any of the 3 is the right insulation solution for this application.
A little overview of the 3 types so you can chose the best for your application
The reflective facer on DuroFoam insulation contains a thin layer of foil embedded within the film. The reflective facer does not increase the nominal R-value of DuroFoam insulation. The green face of DuroFoam insulation should be left exposed to make use of the markings on this face provided for easy cutting of insulation and spacing of interior framing as required.
After you have chosen which type of PlastiSpan insulation you are going to use and have removed all your existing siding, you need to plan out the joints. Apply one of the PlastiSpan insulation products over the exterior of the wood framing. All vertical edges of the PlastiSpan insulation need to be butted tightly together over stud locations for adequate support.
Make sure you are using the correct fasteners. PlastiSpan Insulation must be fastened to framing using fasteners with heads or washers at least ½” diameter where the cladding will be applied directly against the insulation. Fasteners with heads or washers at least 1″ in diameter must be used where an air space will exist between the PlastiSpan insulation and the cladding. (The fasteners are usually a nail with a green washer around it).
A sheathing membrane is not required if all joints between the PlastiSpan insulation and all openings in the wall are taped using a sheathing tape to seal them. Installing exterior cladding; cladding must be attached to the wood framing members so they need to be long enough to penetrate through the PlastiSpan insulation and at least 1″ into the wood framing.
This should finish off the exterior of your home. New doors, new windows and by using PlastiSpan insulation under your sheathing, it will make a huge difference on your energy bills every month, plus increase the comfort inside your home. It’s a win-win situation, and who can resist a win-win?

The correct answer is, people who are looking to improve the energy efficiency of their homes and save on energy costs, and truly, who DOESN’T want that?
People are continually looking at different ways to increase their energy efficiency and decrease their energy costs. So what do they do? Replace windows and doors. Well that’s a great start, but what about all that space between your windows and doors? How much energy do you think is leaving through your walls every day? Parents are always after their kids to shut the door so we don’t let the heat or cool air out but in reality, you could be losing up to 33% of your heating and cooling through your walls each day due to thermal bridges caused by the wood studs that frame your wall.
So how do we solve this problem? That’s where CONTINUOUS exterior INSULATING sheathing OVER THE EXTERIOR OF YOUR FRAMED WALL comes in. Think of CONTINUOUS exterior INSULATING sheathing as MONOLITHIC blanket that you wrap around your home, keeping the temperature stable, and increasing the energy efficiency.That’s where continuous exterior insulating sheathing over the exterior of your wood framed wall comes in. Think of exterior insulating sheathing insulation a monolithic blanket that you wrap around your home, keeping the temperature stable, and increasing the energy efficiency. If this is something you want to pursue to save on energy costs and improve the overall comfort of your home, let’s take a look at EPS rigid insulation as a solution
It is more cost effective and time effective to increase the R-value of your above grade wall by insulating from the outside in then from the inside out. Make sure you check your local building code; see what they have for rules, requirements and restrictions. This will save you from problems later on.
We have a good selection of rigid insulation that can be used as continuous exterior insulating sheathing. By adding PlastiSpan, PlastiSpan HD, EnerSpan or DuroFoam/DuroSpan insulation to your home we will increase your energy efficiency and decrease your costs. Just for easier reading, all insulation will be called PlastiSpan/EnerSpan insulation from here on, but any of the 6 products mentioned above is the right insulation solution for this application.

Fasteners with heads or washers at least 1″ (25 mm) in diameter must be used where an air space will exist between the continuous insulating sheathing and the cladding. (The fasteners are usually a nail with a green washer around it). When you are installing exterior cladding; cladding must be attached to the wood framing members so fasteners need to be long enough to penetrate through the exterior insulating sheathing and at least 1″ (25 mm) into the wood framing.
A separate sheathing membrane is not required if all joints between the exterior insulating sheathing boards are taped using a sheathing tape to seal them.
This should finish off the exterior insulation of your home. New doors, new windows and using continuous exterior insulating sheathing under your cladding, it will make a huge difference on your energy bills every month, plus increase the comfort inside your home. It’s a win-win situation, and who can resist a win-win?

As we move into the final stages of building and insulating our commercial building, let’s take a look at what we have this far. First, the below grade insulation solutions created an excellent, energy-efficient foundation for the building. Then we moved on to the exterior above grade walls with a host of insulation options ranging from rigid foam products to insulated building systems. Now, to keep the momentum and high-performing thermal envelope going, we will finish off our series with insulated roofing solutions.
Most commercial structures have a flat roof; but whether the roof is flat or pitched, you can still insulate it to provide the most energy efficient building, keeping your heating and cooling costs low. This adds value not just to the quality and comfort of the structure, but to your bottom line as well.
One product to consider for your roofing needs is PlastiSpan® Sloped Insulation. PlastiSpan sloped insulation board can be used for new and maintenance roofing projects of all sizes and is suitable for use with all types of roofing systems. Because PlastiSpan sloped insulation board is an expanded polystyrene (EPS) insulation, design thermal resistance values provided are not subject to thermal drift. (Meaning your R-value is the same now and will remain the same for the life of the product) PlastiSpan® insulation can be used in more than just a sloped roof solution. Other applications for commercial construction include standing seam, built-up roofing, fire-rated assemblies, single-ply roofing and (in the case of pitched roofs) cathedral ceilings. You do not have to sacrifice design and architecture to get the insulating values you need.
What if you don’t need a specially designed sloped roofing insulation? DuroFoam® Insulation, a laminated rigid foam board can also be used for roofing assemblies to ensure the energy efficiency of your building. The roof area can be the area of highest heat loss in buildings. In order to conserve energy and to make buildings more comfortable, building codes stipulate higher thermal resistances (R-values) for the roof area compared to other building components.
If you need a higher R-value solution for the roof, consider using an EPS product infused with NEOPOR® Graphite bead, providing R4.7 per inch. This product, known as EnerSpan® Insulation is another roofing insulation option, and works well in commercial applications.
EnerSpan® is a moulded graphite expanded polystyrene (GPS) insulation with a silver- gray colour. Manufactured using Neopor® provided by BASF, a graphite-enhanced raw material that reduces radiation heat transfer resulting in higher thermal resistance (R-value) of 4.7 per inch
The last roofing solution we are covering today is an insulated building system, Insulspan Structural Insulating Panels (SIPs) Unlike the other flat roof solutions, SIPS are the complete, drop-in-place roof component that provides EPS insulation and structural strength. Insulspan® Structural Insulated Panels – Insulspan SIP roof assemblies provide higher R-values than typical wood-framed construction alternates as there are significantly fewer thermal bridges. Longer spans, higher R-values, reduced site time, and less waste from building materials makes SIPs an excellent option for commercial roofing.
Compared to conventional foundation walls, ICFs require more rebar. However you can have a 6” thick concrete wall with ICF opposed to an 8” conventional foundation wall in most cases. Therefore the extra rebar can save you 2” of concrete throughout your foundation walls.
Since ICFs incorporate more rebar and are considered reinforced concrete walls, they will allow you to build a taller wall giving you a higher ceiling height compared to conventional concrete walls.
Rebar is used to solve structural design requirements related primarily to compression, tension and shear loads. Rebar will also control concrete shrinkage cracks.
Vertical Rebar in the Footing
Steel reinforcing dowels should extend a minimum of 40 times bar diameter in height from the top of the footing to match the size, spacing and position of the vertical reinforcement required in the foundation wall.
Concrete is strong under compression loads, but tensile strength is much lower. Rebar for below grade foundation walls with backfill on the exterior face is always installed in the inside third of the wall which is the tension side of the wall. For above grade or Party Wall applications the rebar is typically placed in the middle of the wall.
When you look in the Advantage ICF block you will see rebar clips on the plastic webs that space the 2 layers of EPS.
Horizontal Rebar in ICF Courses
Once the first course of ICFs is complete, place rebar horizontally in the appropriate rebar clips in the web, following your engineering specifications (or the design tables in the Advantage ICF System Technical Manual). The horizontal rebar is staggered in order to allow the vertical rebar to be placed between the horizontal bars after all the courses are in place. For below grade ICF Walls install your horizontal rebar in clip #1 (the first inside rebar saddle) on the first row of block and #3 (the third rebar saddle) on the second row and alternating between #1 and #3 for all the sub sequential courses of block.
Rebar is typically on the tension side of the wall (or the inner third in most cases) However, for a more in-depth descriptions, see the Advantage ICF System Technical Manual.
Staggering the rebar from row to row creates a “weave” effect that enables the horizontal rebar to cage (another term “hold” works also) your vertical rebar in place. Vertical rebar is installed once the wall is at full height.
Install the specified vertical reinforcing steel by sliding it down between the offset lengths of horizontal rebar. This creates a ‘weave’ effect that enables the horizontal rebar to hold the vertical rebar in place.
● Make sure you know where on the job site you want the rebar unloaded.
● Keep the rebar as clean as possible from dirt and other contamination as this will affect the performance
● Cut 4 foot lengths and pre-bend them for corners and T-Walls
● Have a proper rebar cutter and bender on site or arrange to have this done for you prior to having the rebar delivered to achieve required tolerances.
● Place plastic caps over the top of vertical rebar sticking out of footings or walls to prevent injury from sharp ends .
You can click the following link to find out what rebar you will need for your job.
It is critical to review all applicable building codes and ICF manufacture’s engineering, technical manuals as well as Code Reports to understand the proper spacing and sizing requirements of rebar.

Last week we covered what an energy efficient commercial building looks like below grade. Now we are continuing with our build as we move to the types of products and construction methods for the above grade walls. Our goal with this building is to ensure that we maintain an energy efficient thermal envelope for the highest performing structure.
Now that we have moved above-grade, the options available to builders and developers alike are much greater than below-grade. It is a good practice to always check with the local building codes prior to making your product selections for the project.
Some key factors to consider when deciding on your construction materials include quality of materials, technical support during your build process, and job site labor shortages that are sweeping the industry. Because we are a vertically-integrated organization, we maintain quality throughout the manufacturing process. The products we are about to cover range in installation skill, but in general will help your project come together quickly, to meet your completion deadlines.
The first wall system we are going to cover for a commercial building is the Advantage ICF System®. Our patented forming system provides 5 steps in 1: Structural strength, studding, vapour barrier, air barrier and external sheathing resulting in reduced construction time. Advantage ICF System makes your building energy efficient, quiet and comfortable. ICF construction is the fastest growing construction method for both full commercial and renovation projects. To learn more about how the Advantage ICF System can be used in your next commercial project: CLICK HERE
Another common construction method for insulated wall systems in commercial construction are Precast Concrete Tilt up wall panels. Precast concrete panels in walls and floors can be easily and economically insulated by incorporating Plasti-Fab PlastiSpan insulation into the panel at time of manufacture. The panel when placed provides a fully insulated finished wall or floor section. Learn More
We recently had an in depth blog series on our next exterior insulating wall system Exterior Insulating Finishing Systems also known as EIFS. PlastiSpan EFS insulation used in EIFS applications covers the outside of the building so that the structure is isolated from the wide temperature fluctuations of the climate. This reduces expansion and contraction of the structure and stabilizes interior temperatures. Learn More
Before we talk about exterior insulating sheathing solutions, we are going to look at one more insulated building system that is a great solution for commercial construction: Insulspan® Structural Insulated Panels. Some of the benefits of building your commercial walls using the Insulspan SIP System include the increased efficiency of SIPS allows you to downsize your hvac requirements. You can span longer without the need for posts, allowing for an open floor plan. Varying thicknesses meet the specific building code requirements for your area easily. Use our RTA solution to easily repeat structures across the country, Meet energy codes in any location, without altering the design or materials. To learn more about how the Insulspan SIP System can help you achieve your energy efficient project goals, CLICK HERE.
The last type of insulation solutions we will be covering today for above grade walls in commercial construction is exterior insulating sheathing, also known as continuous insulation. While we have many different options for exterior sheathing, we are going to highlight 3 main choices for commercial construction. These insulation solutions are easy to cut and install on site, lightweight and easy to handle, and are available in a variety of thicknesses to provide you with the R-values you need to achieve your energy ratings on your project.

Stay tuned for next week when we put the roof on our commercial building!
Last week we introduced our commercial series in EPS (expanded Polystyrene) product solutions, and this week we jump into the below grade products and applications. While all the building components & materials are important to a well insulated and energy efficient structure, it all starts with a good foundation.
Under slab insulation for energy efficiency and compressive resistance is key in commercial construction. Selection of which product you need under your slab is dependent on local building codes, loads calculated for the building, and energy requirements.
PlastiSpan® EPS Insulation has multiple thicknesses, R-values and compressive resistance characteristics to help you meet those requirements. The closed cell structure of the EPS is resistant to moisture, eliminates thermal bridging, and maintains its R-value reducing overall energy costs of the building. Some of our under slab rigid insulation include:
PlastiSpan® HD Insulation: This is a type 2 insulation with 16 psi and an R-value of 4.04 per inch for Canada or R4.2 per inch in the US. PlastiSpan® HD is listed with CAN-ULC, CCMC 12425-L and ASTM C578. Learn More about this product: Canada | USA
PlastiSpan® 20 Insulation: PlastiSpan 20 insulation’s minimum compressive resistance of 140 kPa (20 psi) makes it ideal to insulate low temperature freezer floors or for use in other applications where moderate loads are expected. Learn more here!
PlastiSpan® 25 Insulation: Using PlastiSpan 25 insulation underslab provides 25 psi compressive resistance with 4.27 R-value per inch. PlastiSpan 25 meets code requirements and is easy to cut and install in commercial applications. Canada | USA
PlastiSpan® 30 Insulation: PlastiSpan® 30 Insulation: The closed cell structure of PlastiSpan 30 resists water absorption so it will retain its R-value even in applications where severe temperature differentials occur, making it a great under slab solution for commercial buildings. Learn More about this product: Canada | USA
PlastiSpan® 40 Insulation: High compressive resistance for geotechnical applications – Compressive Strength 40 psi, No thermal drift, Less than 2% water absorption Learn More about this product: Canada | USA
With the need for Radon Mitigation systems on the rise, Plasti-Fab developed an insulation solution to both insulate under your slab while allowing Radon to move through the mitigation system and out of your structure. Radon Guard is a key component in a Radon mitigation system.
Radon Guard insulation is the code compliant one-to-one replacement for a 100 mm thick layer of granular material, the prescriptive solution required by building codes. Watch how to install Radon Guard Now.
The last area of below grade solutions we are covering today are geotechnical. Sometimes soil integrity is not ideal for a large commercial structure, or there may be other geotechnical requirements that need to be addressed in order to make the structure a success. In those instances, Plasti-Fab has two specific products: GeoVoid® Compressible Fill Material & GeoSpan® Compressible Fill material.
GeoVoid® and GeoSpan® are compressible fill material expanded polystyrene products designed to act as a compressible medium between swelling soils and structural elements. Unaffected By water, Engineered for your commercial construction needs, easily adaptable on site to meet dimensions.
