Due to various factors such as rising energy costs, and the need to protect the environment through implementing efficiency measure in our homes and places of work; many are considering insulating their home.

This offers the great advantage of preventing heating or cooling losses between the building and outside environment.

However, having there has been much concern drawn towards the flammability of materials, as you home will be sealed inside such materials and many such home owners have experienced first-hand that this can greatly increase your exposure to fire hazards.

Consequently, it’s imperative when deciding on insulation for your property to first ask yourself, is insulation fire resistant?

Of the various insulation methods and materials, fire hazards have also in the past been connected to the use of spray foam and because of its popularity and relatively low cost you should also be asking, is spray foam flammable?

Factors Which Affect Flame Resistance

As fire resilience or vulnerability is naturally something important which should be considered when comparing and selecting the right insulation type for you, these are some of the factors which you should be aware of:

  • Mineral wool and fiberglass insulation are generally regarded as fire resistant, but usually require additional chemical applications, in order to reduce their susceptibility to fire hazards. Additionally, these insulation types should not be exposed after installation.
  • Insulation made of cellulose materials is highly susceptible to fire, and, as such, is usually heavily treated with chemicals to improve overall fire resilience. However, these measures are not considered adequate, as they are still commonly regarded as highly combustible.
  • Spray foam has traditionally been regarded as hazardous in event of a fire, but with the release of various newer chemical formulae, it largely depends on the type of foam you use, and the application procedure deplyed. In general however, modern spray foams may still degrade and even ignite at extremely high temperatures.

Take the Appropriate Precautions

Even though the type of insulation is key in deciding, is insulation fire resistant, there are other factors which can greatly influence the performance of insulation as a fire barrier or conduit.

The height, design and location of a building can be a significant factor in deciding on the type of insulation. In addition to this, the application of insulation materials should also be applied in the correct positions, which means it may not always be advisable to go it alone when taking such a bit step.

It would be best to consult with professionals before any decision is made, as they will be aware of the various precautions and factors related to fire safety and in addition to this, they will also be aware of the relevant regulations governing the use of insulation in homes and buildings.

Spray Foam Benefits

Spray foam has fast become one of the most popular options for all types of property, because of its cost-effectiveness over time.

However, many homeowners are still concerned about spray foam safety, and wonder, in particular, whether spray foam’s flammable, or fully resistant to fire.

Well, simply put older types of spray foam may in fact increase the flammability of your home, but the newer products such as Icynene Classic O Plus and Cellulose Spray can either be fire retardant or even fire resistant.

Selecting the right one, however, will also depend on a variety of additional factors, but generally put, these types of spray foam insulation are the safest forms of foam on the market today.

What about Polyurethane Spray Foam?

This type of spray foam is widely regarded as a fire hazard and should generally be avoided when selecting a specific type of spray foam for your house. When asking yourself is spray foam flammable, the answer for this type is a resounding yes.

But in addition to being flammable, this kind of spray foam has chemical properties that when produces smoke, which can render occupants of a house unconscious and even lead to temporary blindness.

This is best avoided, as it will no doubt make your building unsafe and does not meet the regulatory requirements for insulating a home.

Fire Retardant and Fire Resistant

It is common that several insulation applications, including spray foam, are coated with fire retardants, in order to improve their fire rating.

For fire ratings of 1 (which is the best fire rating), these types of fire resistant spray foams comply with all relevant building safety regulations, and can be used on residential, commercial and industrial properties.

Other measures may be termed fire retardant, meaning that the insulation material will slow down the fire, but not stop it from spreading. This however can provide essential lead time, which can greatly improve the safety of occupants and response of fire fighters in the event a fire hazard does occur.

Speak to The Professionals

With all there are important considerations when making your decision, such as is insulation fire resistant? And is spray foam flammable. Well, deciding which is best can be a daunting task, but you should preferably consult with an expert before deciding for yourself.

This takes the stress out of the job and you end up saving much more in the long run as professionals have the relevant experience and knowledge, to choose the best option for your home and your budget.
