New product lineup! Achieving both workability and airtightness for main building and roof insulation! High-performance rigid polyurethane foam insulation panel 'Racty Mp' compatible with insulation grades 6 and 7.
"Racty Mp" is a high-performance rigid urethane foam insulation board designed for filling between rafters, developed for construction companies and design offices promoting high thermal insulation and airtightness in residential buildings. It addresses common challenges in improving the insulation performance of wooden houses, such as the "labor involved in roofing and rafter construction" and the "risks of air leakage and insulation deficiencies." With its excellent thermal conductivity, it features a thin, high-insulation design that strongly supports the insulation performance grades of 6 and 7 (HEAT20 G2/G3 standards). Its high workability, achieved through pre-cutting and dedicated fittings, helps resolve issues related to labor shortages and variations in construction quality on-site.

Achieving both construction performance and airtightness for the main building and roof insulation! High-performance rigid urethane foam insulation panel 'Racty Mp' compatible with insulation grades 6 and 7. [Shortened construction period, gap-free installation, realizing high-performance housing at HEAT20 G2/G3 standards.]
"I want a product that can add insulation to the roof from the inside after the framing is completed."
The development of the Ractee Mp began with this comment from a construction company in the Tohoku region. We conducted three monitoring installations at the construction company's site and made improvements based on the feedback received each time. In this article, we will introduce the background of this process.
