Spray Foam Insulation Health Hazards: The Real Story

Spray Foam Insulation Health Hazards

There are two different kinds of spray foam– the open cell type and the closed cell type. That doesn’t mean one is open for business, and the other one is retired! Both very much do the business – and they both do it well!

However, one form is known to possess some spray foam insulation health hazards. Can you guess which one? No need to! We’ll tell you right here! Keep reading to find out more…

Closed Cell Spray Foam: How It Works

Closed cell foam forms a hard and inflexible finished product. This can help to strengthen the structure of your property, with R-values reaching up to 8.0 per inch.

This is a dense product that is resistant to water degradation and penetration. In turn, this helps to combat moisture build-up and condensation issues.

Closed cell foam is thick enough to insulate air flow, preventing draughts, and helping to maintain a regulated room temperature all year round. However, when it comes to spray foam insulation health hazards, this one definitely isn’t the best option on offer.

Closed Cell Spray Foam Insulation Health Hazards

There are a number of spray foam insulation health hazards associated with closed sell spray foam. These may include some or all of the following:

  • Asthma
  • Sensitisation
  • Lung damage
  • Other respiratory and breathing problems

This is mainly based on older, closed cell forms of insulation, such as Polyurethane, but modern alternatives (such as our open cell Home Logic Spray Foam), offer an air quality improving alternative!

Open Cell Spray Foam: What’s It All About?

In comparison, open cell spray foam creates a soft, spongy like finish to the material. It is nowhere near as hard as the closed cell form. As a result, when set in place, it can possess a lesser R-value than the closed form – coming in at around 3.6 to 4.8 per inch.

The installation process is similar to (if not the exact same as) the procedure used for closed cell spray foam. The effects are diverse though. Open cell spray foam expands on impact with the area of application, so it’s much easier to fill those awkward-to-reach areas.

This includes: ceiling cavities, crawl spaces and other areas that are difficult to reach or seal with closed cell foam.

Open Cell Spray Foam: It’s All In The Expansion

The expansion process is really what makes the open cell route more appealing. This hermetically seals the designated area, and allows for all-encompassing protection.

In general, the R value and heat resistance may be lower, but the potential for complete and effective coverage is made a lot more likely.

Besides, open cell foam is still extremely dense, and it does provide solid insulation all year round.

Stay Open – Stay Healthy!

Open cell spray foam is by far the healthiest option when in comparison to the closed cell form. Home Logic Spray Foam is made up of two separate compounds – water and isocyanates. These compounds are completely safe, and non-toxic for both humans and animals.

It is these isocyanates that have caused debates and raised arguments in the past. Technically, these are a class of highly reactive chemicals. They formulate to create a compound that is used in abundance across industrial, commercial and retail applications.

We here at Home Logic are a trusted BBA Approved company. With this great power comes great responsibility!

It is our responsibility to guarantee the correct application of our products, by ensuring adequate ventilation and re-occupancy practices for a safe living environment.

Open Cell Spray Foam: Fire Retardant Properties

It’s also extremely important to ensure our products remain as safe as possible in the event of a fire. Insulation is going to play a vital role in your property’s structure, so it needs to be fire retardant at the very least.

Home Logic Spray Foam meets all code requirements relating to fire safety – remaining burn proof for up to 30 minutes. It also fulfils the requirements for a Class-0 surface, as summarised in Paragraph A12(b) of ‘Fire safety: Approved Document B’.
