So, we're back in the paper! Page 11 and 12 of the Advance. Don't be confused, I actually wrote the article - not Ben.
Well, you've been very patient for the big news, so here it is!
The provincial government has now matched the 25% funding increase made by the federal government!
This is fantastic news as it means more money in your pockets - and even greater reason to act now.
It's simple:
1. Book your audit
2. Make the changes outlined in your personalized report
3. Book your post-retrofit audit
4. Wait for money to arrive in the mail!
Easy-peasy.

You should consider consulting with an expert (heritage mason, or P.Eng) before applying spray polyurethane foam insulation to the interior of a stone foundation. From the age of your house I suspect your foundation is stone. The lime mortar used during this era is a remarkable material; resilient and durable, but it also designed to be permeable to water. The low perm rate of the polyurethane will trap moisture within the foundation and contribute to the growth of mold within it, and damage the mortar.
ReplyDeleteAs well, by insulating the warm side of a stone wall, it will be at risk to frost or freezing damage in the winter. The heat loss into the wall is currently preventing this.
Finally, spraying the wall will make any repairs to the mortar that are required in the future very difficult.
If your foundation is stone, you may have been given poor advice about using spray polyurethane on the interior. While you will save money and energy, there is a high probability that you will severely degrade the performance and life span of your foundation system. There are also risks to excavating a stone foundation if you decide to insulate the cold side.
Good luck with your project, but be wary of the advice you are given. Many people call themselves experts, but have limited knowledge of building systems.

Great Advice, thanks Chris.
ReplyDeleteI'll be sure to go over these very legitimate concerns before we actually tackle the project.
