Closed Cell Spray Foam Insulation (2lb Medium Density)
Exotherm Spray Foam Systems specializes in 2lb medium-density closed-cell SPF insulation, which is a rigid insulating material with the highest LTTR (Long Term Thermal Resistance) of any insulation product on the market. Its R-value is R6 per inch and when the required minimum thickness of 50mm is installed, it is the only all-in-one system available, providing both a vapor as well as an air barrier.
2lb closed-cell is a premium product for those looking for superior insulation and overall energy efficiency, best used in walls, ceilings, floors, garages or anywhere its unmatched performance may be required.
Let us take a closer look at what is closed-cell SPF Insulation, and why spray foam insulation might be an excellent choice for your home.
What Is SPF Insulation for Buildings?
Spray polyurethane foam, also known as SPF, insulation presents a spray-applied plastic that is commonly used to insulate buildings, as well as seal any gaps and cracks. SPF insulation is known for making buildings considerably more comfortable and energy-efficient due to its ability to resist heat transfer and reduce unwanted air infiltration through seams, cracks, and joints.
What Is Closed Cell Foam?
Spray Polyurethane Foam (SPF) insulation can be categorized into two types of products:
- Two-component open-cell foam (ocSPF)
- Two-component closed-cell foam (ccSPF)
Open-cell foam insulation is characterized by having more than half of its cells open, which gives it a unique ability to operate like a spring and return to its original state after being compressed.
Closed-cell insulation, on the other hand, is characterized by having its cells fully enclosed by their walls and not interconnecting with other cells. At Exotherm Spray Foam Systems Inc., we specialize in closed-cell spray foam insulation for homes, as it is superior to open-cell insulation in many ways. Not only does it offer a wide variety of material and density options, but it performs incredibly well in reducing liquid and gas flow.

Benefits of 2lb closed cell SPF insulation
- Superior insulation performance: 2lb closed cell SPF insulation has a high R-value, which means that it provides excellent thermal insulation and helps to reduce energy consumption.
- Moisture resistance: 2lb closed cell SPF insulation is impermeable to moisture, which makes it an ideal choice for areas that are prone to high humidity or water exposure. This can help to prevent mold growth and water damage.
- High durability: 2lb closed cell SPF insulation is highly resistant to damage from impacts, vibrations and settling, which makes it a durable and long-lasting insulation material.
- Air sealing properties: 2lb closed cell SPF insulation creates an air barrier that can help to prevent air leaks and drafts, which can improve indoor air quality and reduce energy loss.
- Versatility: 2lb closed cell SPF insulation can be used in a wide range of applications, including walls, roofs and foundations and can be applied in a variety of thicknesses to meet the specific insulation needs of different buildings and structures.
What Is Medium-Density SPF Insulation?
In addition to being categorized as either ocSPF or ccSPF, foam spray insulation can be categorized as a high-density, medium-density, and low-density product.
At Exotherm Spray Foam Systems Inc., we offer 2lb medium-density SPF insulation. This product always comes in the form of closed-cell foam insulation spray and acts as a water, air, vapour, and even noise barrier. It offers the greatest R-value per inch possible and is often used for continuous insulation, unvented attic applications, and interior wall cavity fill.
Medium-density foam insulation can be applied as low- or high-pressure two-component spray foam.
Downsides to Spray Foam Insulation
The major advantage of spray foam insulation is that it fills even the smallest gaps, creating an airtight seal. However, this airtightness can lead to superheating and carbon monoxide poisoning in buildings with poor ventilation.
While we want our buildings to be as airtight and as well-insulated as possible, it is important to ensure that a proper ventilation system is in place. Air leakage through the building envelope may cause moisture-related issues and poor indoor air quality, – instead, the building envelope itself should remain airtight, with a mechanical ventilation system and passive ventilation (windows) taking care of the airflow.
Closed-Cell Spray Foam Insulation R Value
The R-value of closed-cell spray foam insulation is R-6.5 to R-7 per inch, considerably higher than the R-value of most other insulation types. The impressive R-value allows medium-density spray foam insulation to be effectively used for tight applications that require the highest possible R-value in the least amount of space.
How Long Does Spray Foam Insulation Last?
Spray foam insulation has an estimated life expectancy of 80 to 100 years and requires little to no maintenance at all. Closed-cell SPF insulation is strong and can last as long as your building can. Unlike fiberglass or cellulose, spray foam won’t deteriorate, sag, or settle over time.
Is Spray Foam Insulation Worth the Price?
There is no question that spray foam insulation is well worth the price. In addition to its impressive life expectancy and low maintenance requirements, spray foam insulation has the potential to save you up to 50% on your energy bills. The insulation’s highly effective heat retention means that you simply won’t need to use as much energy to keep your home warm

Closed-Cell Spray Foam Insulation FAQ
While it is possible to install spray foam insulation in a DIY manner, doing so carries the risk of not properly sealing the area and allowing moisture penetration. Proper home insulation can save you hundreds of dollars on energy bills per month, and leaving it to a professional is often the best course of action to achieve maximum savings.
Spray foam insulation is not recommended to be used around lighting, near electrical work, and in basement leaks.
Spring and summer offer ideal conditions for achieving the best results with SPF insulation, as there is an increased risk of creating condensation in colder temperatures. That being said, an experienced contractor can still apply spray foam insulation in winter, – they will simply have to spend more time and use more product to ensure a proper air seal.
Closed-cell spray foam insulation has a high R-value of R-7 per inch. To compare, open-cell spray foam insulation has an R-value of R-3.8 per inch.
Yes, spray foam insulation in Toronto is known for its ability to keep a house warm and reduce energy loss, so that you and your family can feel comfortable all year round.
