The Roof Tech RT2-04-MINBUTYL is a high-quality butyl tape designed to provide superior sealing and waterproofing for various roofing applications. Targeting the needs of professionals and DIY enthusiasts alike, this tape delivers durability and performance, significantly enhancing the longevity and reliability of roofing installations.
The Roof Tech RT2-04-MINBUTYL offers outstanding adhesion properties, ensuring that it sticks firmly to surfaces. This feature is crucial for creating a reliable seal that can withstand various environmental conditions, making it an essential product for effective roofing solutions.
Constructed from robust materials, the butyl tape guarantees excellent durability and long-lasting performance. The Roof Tech RT2-04-MINBUTYL is resistant to aging and can endure exposure to UV rays, moisture, and extreme temperatures, ensuring your roofing projects remain protected over time.
Designed for user convenience, the application process for the Roof Tech RT2-04-MINBUTYL is straightforward and efficient. The tape can be cut to the desired length, and its flexibility allows for easy handling around corners and irregular surfaces, making it ideal for any roofing task.
This butyl tape is suitable for a range of applications beyond roofing, including sealing gaps in windows and doors, making it a versatile choice for both professional contractors and home improvement projects. The Roof Tech RT2-04-MINBUTYL is a multipurpose solution that meets various sealing needs.
One of the standout features of the Roof Tech RT2-04-MINBUTYL is its excellent weather resistance. It performs reliably in both wet and dry conditions, ensuring that your roofing solutions remain effective, regardless of the weather.
The Roof Tech RT2-04-MINBUTYL operates by utilizing its strong adhesive properties to create an impermeable seal when applied. This ensures that water and air do not penetrate the roofing structure, providing maximum protection against leaks and other moisture-related issues.
The key component of the product, the adhesive layer, is formulated to bond securely with various substrates, enhancing the tape's sealing capabilities. This layer initiates an immediate bond upon contact, promoting effective sealing.
The butyl material provides structural integrity and ensures that the tape remains intact under stress. Its flexibility allows it to adapt to movements within the building materials, preventing cracks and separating over time.
The outer layer of the Roof Tech RT2-04-MINBUTYL tape is engineered to resist environmental factors, protecting the adhesive layer and maintaining optimal performance in diverse climates.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
