Why Spray Foam is the Best Underfloor Insulation for Your home

Now you have decided you want to install underfloor installation, you have to decide which form of insulation to use.

We’ll tell you why we think Spray Foam insulation is the best underfloor insulation for your home.

Criteria for Choosing the Best Underfloor Insulation

Here are some factor to consider when selecting the best underfloor insulation for your home:

• Does it hold moisture? Preferably not, moisture can mean mold, rot and smells
• Does it spring-back to maintain its loft over a long period of time? Ideally YES – to be effective and continue to inhibit airflow your insulation to hold its shape.
• How is it secured and does it provide complete coverage for optimum insulation value? You want the insulation to stay in place and to have a high R value.
• Is it supplied in long rolls for ease of installation, minimal joining and maximum effectiveness? Breaks in the insulation due to joins will be detrimental to the integrity of the insulation as the provide a weakness for air to flow).

What is R-Value

This is a measure of a material’s thermal resistance – basically how much it inhibits or blocks the transfer of heat. The higher the R-value, the more heat a material blocks.

However, be careful as the ‘R-value’ of an insulation is not always the only or best measure of its effectiveness.

There are times where the reported R-Value can be high and not effective.

This occurs if the insulation is not properly installed or if there is a strong draft; therefore, ensure that you employ the right people and that they use the right materials. Some of this can be mitigated.

Using qualified, experienced installers can ensure your insulation is properly installed.

Why We Think Spray Polyurethane Foam (SPF) is the Best Underfloor Insulation

First the mechanics: Spray polyurethane foam insulation is sprayed directly onto the underneath of timber floors. The foam applied as a liquid that expands into a foam and cures in seconds.

Here are the reasons we think SPF is your best option for insulating your floors:

• Polyurethane has the highest R-value of any commercially-available insulation material.

• Because it is applied as a liquid, this enables it to flow and fill cracks and gaps effectively – ensuring a tighter seal than bulk insulation like glass wool, wool, cellulose fibre.

• The tight seal means there is minimal transfer of heat as well as the movement of airborne allergens like pollen and dust – good news for allergies sufferers.

• Once it has cured, it will not shrink, settle or disintegrate. (The material is inert and does not release any gases).

• It does not hold moisture and resists water penetration (which means no danger of spores, rot or fungus)
