How to Install RetroFoam in Homes with Cedar Shake Siding

Written by Amanda Emery | Nov 6, 2024 1:00:00 PM

When insulating your home with RetroFoam, the installation process can vary depending on your exterior – especially with cedar shake siding.

Cedar shake provides a classic look to your home, but its unique structure requires special attention during foam installation. If you’re considering installing RetroFoam in a home with cedar shake siding, here’s a step-by-step look at what you can expect from start to finish.

Preparing Your Home for Insulation with Cedar Shake Siding

Before getting started, it’s important to communicate with your insulation contractor about protecting your landscaping.

The installation process can be messy, and ensuring your shrubs, flower beds, and outdoor furniture are safe from debris will help keep your yard looking great during and after the installation.

Protecting Landscaping and Outdoor Features

The installation crew will use tarps or protective coverings to safeguard landscaping and other elements near your home.

This step helps ensure that any foam particles, wood shavings, or other materials from the cedar shake siding removal don’t end up damaging your yard.

Removing Cedar Shake Siding for Injection Foam Insulation Installation

For homes with cedar shake siding, the installation team has two primary options to access the wall cavities for the injection foam.

Option One: Lifting and Removing Cedar Shake

In some cases, the team may be able to carefully pry up each cedar shake to gain access without removing or damaging the shakes.

However, this approach depends heavily on your home’s siding layout and the placement of nails and overlaps. Sometimes, nails or overlapping shakes make it difficult to lift them without causing damage, making this option less reliable.

Option Two: Scoring and Cutting Cedar Shakes for Clean Removal

The most common and recommended approach is to score the top of each shake where it meets the shake above it.

The team can lift the shake cleanly by cutting through this section without risking cracks or splinters. This method helps ensure a seamless look when the shakes are reinstalled.

Tip: Each cedar shake is carefully numbered and cataloged before removal. This system allows the crew to reattach each shake in its original position, ensuring the final look mirrors the initial layout perfectly.

Installing RetroFoam Insulation Behind Cedar Shake Siding

Once the cedar shakes are removed, the sheathing (the wall structure underneath the siding) is exposed, allowing the crew to drill into it and inject the foam insulation.

Drilling into Sheathing for Injection Foam Access

With the sheathing visible, the crew will drill holes to create access points for the injection foam.

Each hole allows the installer to reach every stud cavity inside the walls. This process includes checking for hidden or small obstructions and ensuring the hose reaches both the top and bottom of each cavity so no section is left uninsulated.

Injecting RetroFoam into Wall Cavities

After creating access points, the team will inject RetroFoam into each cavity. 

The foam flows through each section to fill the entire cavity, reducing air leaks by creating an air seal and improving the overall insulation. This process will keep your home comfortable while minimizing energy costs.

Reinstalling Cedar Shakes After Foam Installation

Once the installation process is complete, it’s time to put the cedar shakes back in place.

Reattaching the Cedar Shakes

Each shake is realigned with its original position on the siding and secured with nails to ensure stability.

While the nails are initially visible, there are options to cover nail heads for a cleaner finish, depending on your preferences.

Finishing Touches: The installation team will ensure each shake aligns like a puzzle piece, keeping the original look intact. This step is crucial to maintaining the aesthetic of cedar shake siding, especially in older homes where each shake has naturally weathered over time.

Thorough Cleanup and Final Walkthrough

Foam insulation installation can generate wood shavings and foam particles, especially with cedar shake removal.

The crew will complete a thorough cleanup, including:

  • Removing foam and debris from the yard and surrounding areas.
  • Clearing wood shavings from around the home.

  • Checking landscaping for any remaining particles.

Once the cleanup is complete, the team will invite you for a final walkthrough. You’ll be able to inspect your home’s exterior and verify that the installation process left it looking as it did before the work started. This inspection is essential, as your familiarity with your home’s exterior allows you to catch any details the crew might overlook.
