Your thoughts on regular vs. spray foam insulation?
Interested in hearing your thoughts/experience in using regular insulation vs. the spray foam insulation.
Our sunroom adjacent to our master bedroom sits on top of our back deck and consequently has 5 exposed walls. Quotes for spray foam insulation are about $2,000 CDN, substantially more expensive then regular insulation.
We plan on putting in a baseboard heater in the sunroom and so we're wondering if we'll have sufficient heat during our cold winter months (up to -20 degrees celsius in January).
Is spray foam realy worth the extra expense?
thanks in advance,
