What’s the Best Insulation for Attics?

Whether you’re focused on keeping your home warmer in the winter, cooler during hot Manitoba summers, or a mix of both, choosing the right attic insulation will play a major role! This is a vital aspect of your home’s energy efficiency and comfort level, so it’s not a decision to make lightly. 

Best Insulation for Attics

Today, we’ll discuss the pros and cons of different materials for attic insulation to help you make a decision.  

Fiberglass Insulation

Fiberglass insulation is one of the most popular materials used for attic insulation. It’s made up of tiny glass fibers that trap air and slow down heat transfer. One of the significant benefits of fiberglass is its affordability, making it a popular choice for many homeowners. It also comes in either roll or batt form, making it easy to work with. 

Pros

  • Affordable  
  • Easy to install  
  • Great for DIY projects  

Cons

  • Fibreglass can cause skin irritation if not handled properly  
  • It’s not as effective in extreme temperatures compared to other materials  

Cellulose Insulation 

This insulation material is made from recycled paper products so it’s touted for being environmentally friendly. It’s treated with fire retardants to prevent potential fire hazards. 

However, it isn’t one of our top choices for attic insulation. One of the big reasons we say this is because if you ever get a leak in your roof, cellulose absorbs the water, and it’s incredibly difficult to dry it out and restore its insulating properties. 

Pros

  • Eco-friendly  
  • Treated with fire retardants for safety  

Cons

  • Absorbs water easily   
  • Difficult to dry out if wet  
  • Doesn’t provide a vapour barrier or an air seal
  • Can negatively affect air quality

Spray Foam Insulation

Spray foam insulation is a stellar choice for attics due to its high R-value, which measures the material’s resistance to heat flow. It’s also great at creating an air seal, ensuring no hot or cold air escapes or enters your home through the attic. 

There are two types of spray foam: open-cell and closed-cell. 

Open-cell is more affordable but has a lower R-value while closed-cell provides better insulation and acts as a vapour barrier.

Pros

  • High R-value    
  • Creates an air seal
  • Can help reduce energy bills  

Cons

  • Can be expensive  
  • Professional installation required
