When it comes to insulating your home, there are many options available, and one popular choice is R-Tech insulation foil. But is it better to install it on the inside or outside of your walls? In this article, we'll explore the benefits and drawbacks of both methods to help you decide what's best for your home.
What is R-Tech Insulation Foil?

R-Tech insulation foil is a type of reflective insulation that is designed to reflect radiant heat rather than absorb it. It's made from a thin, flexible sheet of plastic film that is laminated with a reflective aluminum coating. This coating reflects up to 97% of radiant heat, making it an effective way to keep your home cool in the summer and warm in the winter.
Installing R-Tech Insulation Foil on the Inside

Installing R-Tech insulation foil on the inside of your walls can be a good option if you're looking to retrofit your existing home with insulation. This method involves attaching the foil to the wall studs or joists using a staple gun or adhesive. The foil is then covered with a layer of drywall or paneling to create a smooth surface.
The benefits of installing R-Tech insulation foil on the inside include:
- Easy installation: Installing the foil on the inside is relatively easy and can be done by a DIY homeowner.
- Cost-effective: Installing the foil on the inside is often less expensive than installing it on the outside.
- Improved energy efficiency: The foil can help to reflect radiant heat and improve the overall energy efficiency of your home.
However, there are also some drawbacks to consider:
- Limited access: Installing the foil on the inside can be difficult if you have limited access to the wall cavity.
- Moisture issues: If the foil is not installed correctly, it can create moisture issues and lead to mold and mildew growth.
Installing R-Tech Insulation Foil on the Outside

Installing R-Tech insulation foil on the outside of your walls can be a good option if you're building a new home or re-siding your existing one. This method involves attaching the foil to the exterior of the wall sheathing using a staple gun or adhesive. The foil is then covered with a layer of siding or stucco to create a smooth surface.
The benefits of installing R-Tech insulation foil on the outside include:
- Improved durability: Installing the foil on the outside can help to protect it from damage and extend its lifespan.
- Better moisture protection: The foil can help to protect the wall cavity from moisture and reduce the risk of mold and mildew growth.
- Improved energy efficiency: The foil can help to reflect radiant heat and improve the overall energy efficiency of your home.
However, there are also some drawbacks to consider:
- More difficult installation: Installing the foil on the outside can be more difficult and may require professional assistance.
- Higher cost: Installing the foil on the outside is often more expensive than installing it on the inside.
Conclusion: Whats Best?

So, what's best? Installing R-Tech insulation foil on the inside or outside of your walls? The answer depends on your specific situation and needs. If you're looking for an easy and cost-effective solution, installing the foil on the inside may be the way to go. However, if you're building a new home or re-siding your existing one, installing the foil on the outside may be a better option.
Ultimately, the key to getting the most out of R-Tech insulation foil is to ensure that it's installed correctly. Whether you choose to install it on the inside or outside, make sure to follow the manufacturer's instructions and take the necessary precautions to ensure a successful installation.
