Garaż jak u Wazzupa. Ocieplamy blaszany garaż pianką Polynor.

Summary

In this video, the creators share their journey of insulating their metal garage to make it more functional and comfortable. They begin by cleaning and preparing the space, followed by the application of Polynor foam insulation. The garage, which was prone to condensation and rust, is now being sealed and insulated with the help of specialized tools and techniques. Along with the insulation, they take steps to ensure proper ventilation and protection from moisture, with a focus on making the garage dry and warm for winter use. The process is showcased with a mix of humor and DIY expertise.

Takeaways

• 😀 The episode focuses on insulating a metal garage to improve warmth and prevent moisture buildup.
• 😀 The garage is made of metal with a gable roof, measuring 4x6 meters, and it's being insulated using Polynor foam.
• 😀 The garage was cleaned and cleared before insulation work began, with items temporarily moved outside.
• 😀 The insulation foam used is a closed-cell type, which is vapor-resistant and requires proper ventilation.
• 😀 The foam is applied using a specialized spray gun and nozzle, with attention to achieving an optimal temperature for application (18-23°C).
• 😀 The garage's internal moisture issue (condensation and rusting on metal items) is a primary reason for insulation.
• 😀 The insulation process involves applying foam between battens (structural strips) to create a space for potential future cladding, like OSB panels.
• 😀 The foam has excellent thermal and acoustic properties, with a thermal conductivity (lambda) of 0.30.
• 😀 The application was completed in about 1 hour and 45 minutes, using 36 cans of foam, with the garage now fully insulated except for the doors.
• 😀 Future plans include testing the garage's performance during cold weather with temperature sensors to monitor humidity and condensation inside.

Q & A

What is the primary objective of the project described in the video?

The main goal of the project is to insulate and heatproof a metal garage, ensuring it remains dry and warm during the winter, preventing condensation and rusting of stored items.

What material is used for insulation in the garage?

The garage is insulated using Polynor spray foam, which is a closed-cell foam known for its thermal and acoustic properties.

Why was it necessary to clean the garage before starting the insulation process?

The garage had to be cleaned to create a clear and usable space for insulation, and to prepare the surfaces for better foam application.

What are some of the benefits of using Polynor foam for insulation?

Polynor foam offers several benefits including excellent thermal insulation, resistance to moisture, acoustic properties, and a long lifespan of up to 50 years.

How does the closed-cell nature of Polynor foam differ from open-cell foam?

Closed-cell foam is not permeable to water vapor, making it ideal for preventing condensation inside the garage, unlike open-cell foam which allows moisture to pass through.

What precautions were taken to ensure the proper application of the foam?

The temperature of the surroundings was carefully monitored to ensure optimal foam expansion. The foam was also applied with a specific nozzle for better coverage, and safety equipment like a protective suit was used.

What steps were taken to prepare the garage before applying the foam?

Before applying the foam, the garage was cleaned, necessary electrical cables were fixed, and wooden battens were installed to allow for aesthetic cladding later and to help distribute the foam evenly.

Why was special attention given to the southern wall of the garage?

The southern wall was given special attention because it is exposed to sunlight throughout the day, which can lead to uneven heating and potential damage without proper insulation.

What is the purpose of adding ventilation to the garage?

Ventilation is needed to ensure proper air circulation inside the garage, as Polynor foam is not vapor-permeable and could otherwise trap moisture inside.

What will be tested after the insulation process to evaluate its effectiveness?

After the insulation, the temperature inside the garage will be monitored, and a humidity sensor will check for condensation to ensure the insulation prevents moisture build-up and keeps the garage dry.
