Reliable solutions
for extreme temperatures

Since 2005, Quinsis has been an expert in high-quality insulation and textile solutions for high-temperature applications. The company was founded by Leonard Walpot, who had already built up many years of experience in this technical and demanding sector. His extensive knowledge and passion for the profession still form the foundation of who we are today.

Rooted in expertise


What began with one man and a vision has grown into a company with a strong reputation for customised solutions and technical reliability. Over the years, Leonard developed into a product specialist in dynamic high-temperature solutions, laying the foundation for Quinsis. Since our founding in December 2005, we have continued to grow steadily, driven by expertise, quality, and a strong ‘customer-first’ mentality.
