Why Exterior Walls Need Spray Foam Insulation

Posted by Ecostar Insulation on March 13, 2024

Why Exterior Walls Need Spray Foam InsulationSpray foam insulation in Mississauga is a commonly used spray-applied plastic substance employed for insulating structures and sealing fractures and openings, which, in so doing, enhances the energy efficiency and comfort of buildings. The primary benefit of external wall insulation lies in its ability to retain heat within your residence and keep cold out, thereby diminishing the need for extensive central heating usage. Drafts are invariably discomforting; nobody wants to endure cold conditions within their own household. EcoComfort is the one insulation company that can install attic insulation and wall insulation correctly, ensuring you reap the benefits of keeping your home conditions comfortable.

Reasons Why Exterior Walls Need Spray Foam Insulation

  • Energy efficiency and reducing heating and cooling costs: When insulation is installed correctly, it forms a thermal barrier that blocks heat loss in winter and heat gain in summer. This reduces the workload on heating and cooling systems, leading to decreased energy expenses while ensuring a consistently comfortable indoor climate.
  • Comfort and maintaining a consistent indoor temperature: The insulation forms a thermal barrier, diminishing heat penetration into your residence and maintaining a stable, cozy indoor climate. Consequently, your air conditioning unit operates with greater efficiency, as it isn't constantly battling against external heat infiltration.
  • Moisture control and preventing mold and mildew growth: Effective attic insulation is a formidable method for preventing mold formation. By regulating the temperature and moisture levels within a building, insulation acts as a barrier against mold proliferation. When properly installed, insulation fosters dry and well-controlled environments that deter the growth of mold.
  • Soundproofing and reducing noise from outside: High-traffic areas like apartment complexes are often prone to unwanted noise. Unwanted sounds, including outside noises, tend to disrupt sleep and cause unnecessary panic. Installing insulation helps reduce noise by providing an extra layer to block sound.

Types of Spray Foam Insulation

  • Open-cell foam insulation: Spray foam insulation in Mississauga is categorized as open-cell or closed-cell, depending on the nature of the tiny bubbles (cells) composing the foam. Open cell foam contains cells that are not entirely enclosed, intentionally left open, resulting in a softer and more pliable material.
  • Closed-cell foam insulation: Closed-cell foam consists of cells that are entirely sealed, as implied by its name. These cells are tightly packed together, preventing the infiltration of air and moisture into the foam. As a result, closed-cell foam exhibits significantly greater rigidity and stability compared to open-cell foam.

Benefits of Spray Foam Insulation for Exterior Walls

  • Superior insulation properties compared to traditional insulation: The R-value is a straightforward measure where higher values indicate better insulation. On this scale, spray foam from a top insulation company like EcoComfort stands out as a top performer, particularly closed-cell foam, which can achieve impressive R-values of up to 7.0. Unlike fibreglass insulation, which may sag or settle if improperly installed, spray foam maintains its integrity over time.
  • Long-lasting and durable insulation: Spray foam insulation comprises polyurethane, known for its exceptional durability. When used as insulation, it demonstrates resilience against temperature fluctuations, moisture accumulation, and the proliferation of mold and other organisms.
  • Airtight seal to prevent air leakage: This adaptable product expands upon application, enabling it to fill minor gaps and establish a tight seal, effectively mitigating air leakage and drafts. Spray foam insulation forms a tight seal around a building's structure, effectively blocking airflow by filling in any cracks, openings, or leaks. This results in lower energy consumption for heating and cooling, leading to enhanced comfort and energy efficiency, as well as decreased greenhouse gas emissions.

Installation process of spray foam insulation for exterior walls

  • Start by conducting a test spray to gauge the expansion of the material, which increases to about 100 times its original volume. Be conservative during testing until you have a clear understanding of its expansion properties. Keep in mind that closed-cell spray foam needs to be applied at a thickness of one to two inches to achieve the desired R-value.
  • Spray the foam evenly between the studs and onto the backside of the exterior sheathing, allowing it to expand and fill all gaps. Let the foam set and solidify.
  • Trim any excess foam protruding beyond the studs using a handsaw or blade. Remove any raised foam to ensure it is level with the studs, as uncompressed foam can obstruct the installation of drywall. However, all this said we recommend you use a professional contractor like EcoComfort to do the job for you, ensuring proper insulation installation.
