Last Updated on June 18, 2024 by Spray Foam Insulation Plus

Spray Foam Insulation is a very beneficial alternative to traditional building insulation. It has excellent insulative properties. In older houses where a great chance of leaks is present, it will create a perfect seal. Sealing your house with spray foam insulation helps protect your home from damages that occur due to weather.

How Does Spray Foam Insulation Save Your House Against Weather?

Spray foam insulation saves your house against the weather in many ways, such as:

Spray Foam Insulation Provides Perfect Coverage of Cracks and Holes

Traditional roof insulation can’t fill up small invisible nooks, crannies, and gaps, which can cause heat losses. This is particularly very problematic in old houses where more cracks, holes, and gaps are present. Spray foam insulation fills these empty spaces and leaks perfectly. In this way, it provides you with perfect coverage and works more efficiently.

Spray Foam Insulation Protect Against Moisture

Old houses have many cracks, leaks, and holes that can absorb very high moisture. This moisture creates problems like suffocation and high levels of heat during summer. Spray foam insulation doesn’t absorb moisture but protects your roof from these imperfections, which are very expensive to repair.

Spray Foam Insulation can save House from Water Damage

As discussed, old buildings and houses have a large number of cracks, holes, and gaps in walls, roofs, and ceilings. In the rainy season, your house is at great risk of damage. Because air is trapped in these empty pockets it will encourage water to enter your house. This mess would eventually lead to structural damage and destroy your home’s interior.

How to Seal an Old House by Spray Foam Insulation?

To do sealing in an older house, you must remove the cladding and weather barrier from the house. After that drill the sheathing and inject the loose foam insulation. You should replace the windows. Make sure to install flashing properly integrated with the water repellent barrier, replace the cladding as well as add a rain screen in it. You must wear protective equipment while drilling old insulation.

Which Type Of Spray Foam is Used For Weather Protection?

Closed-cell spray foam insulation is a preferable type for exterior applications due to its excellent performance during severe weather conditions. It increases the ability of old houses to withstand flooding and storm surges. Moreover, spray foam insulation also has a high R-value, vapor retarder, air barrier, and long-term building protection. Its water resistance could be an asset in severe weather conditions. Closed-cell spray foam has the least water permeability and acts as a rainwater barrier to control damage to your older roofs.
