Spray Foam

Full Coverage, Leak-Proof Spray Foam Insulation in Ottawa

Protect your home from leaks with spray foam insulation. FineLines Roofing & Renovations applies spray foam insulation to walls during renovations because it is effective in sealing cracks and preventing heat escape. The spray foam acts as a barrier which locks out moisture and restricts access for rodents and other pests. By choosing spray foam insulation, your home is thoroughly protected and you benefit from increased energy savings.

Two types of Spray Polyurethane Foam

Spray Polyurethane Foam (SPF) comes in a variety of formats one being high pressure foam and low pressure foam. SPF is also available in open-cell and closed-cell compositions.

See the comparison to learn more about the different SPF formulations below:


  • Higher R-value (greater than 6.0 per inch)

  • Restricts moisture permeability

  • Air barrier

  • Stronger and more rigid

  • Medium density (1.75 – 2.25 lbs./ft3)

  • Sound absorption


  • R-value (approximately 3.5 per inch)

  • Allows controlled water permeability

  • Air barrier

  • Less strong and less rigid compared to closed-cell

  • Not ideal for basement foundations or areas where direct contact with water is expected

  • Less dense (0.4 – 1.2 lbs./ft3)

  • Excellent sound absorption

Spray Foam Insulation in Attics

Spray foam applied to the bottom of the roof decks in your attic prevents air from escaping so that the attic space and your home are not too hot in the summer and not too cold in the winter. The insulation reduces the load on your furnace so it doesn’t need to work as hard to maintain a neutral temperature.

Both open-cell and closed-cell polyurethane spray foam can be used as both create a reliable barrier for regulating temperature. Closed-cell foam has a higher R-value which makes it the most effective in sealing cracks.
