Comparing Foam to Batt Insulation
We first need to get a comparison system.
The ‘R-Value’ system is outdated and does not reflect the benefits of Spray Foam.
When viewed in a list with just a price, Fibreglass seems to be the logical ‘cheap’ choice and that is just what it is, it’s ‘1-dimensional.
Fibreglass has a R-Value of 3.
Spray Foam has a R-Value of 6 plus:
- adds 300% structure strength
- resists mould
- water resistant
- monolithic (no seams)
- insect resistant
Fibreglass will slow cold down but Spray Foam stops the cold, adds to the structure, resists mould, rodents and insects, stops air infiltration.
Spray Foam is a multi-dimensional system that the old ‘R-Value’ system does not take into consideration.
Spray Foam costs more upfront but is more cost effective over time making it the inexpensive choice.
