Roof additional insulation board Rakti Mp compatible with insulation grades 6 and 7.
Achieving both the construction performance and airtightness of roof insulation! High-performance urethane insulation boards compatible with insulation grades 6 and 7 [Shortened construction period, realizing HEAT20 G2/G3 housing].
- Achieves "Insulation Grade 6/7" and "ZEH / Standard Energy-Saving Housing" with top-class insulation performance easily. Utilizes non-fluorinated rigid urethane foam, which boasts the highest level of thermal conductivity. Compared to fiber-based insulation materials like glass wool, it can secure the necessary thermal resistance value (R-value) even in limited dimensions between rafters and purlins, allowing for effective use of sloped ceilings and loft spaces. - Dimension design specialized for purlin spacing and reliable airtightness and moisture resistance. Significantly reduces detailed cutting work on-site. Minimizes gaps at the junctions with structural materials (purlins and rafters), preventing variability in the finish by the installer. The independent bubble structure makes it difficult for moisture to pass through, greatly reducing the risk of internal condensation. - Labor-saving and shortening of construction time (improved workability). Lightweight and easy to handle, it simplifies the supporting materials and enables speedy installation. Contributes to labor reduction on carpentry and construction sites and compresses tight schedules. - Ensures continuity with wall insulation and suppresses heat bridges. At the junctions with the exterior wall insulation layer, it maintains the airtight and insulation lines without interruption, achieving high airtightness and high insulation for the entire building (improvement of C-value and UA-value) with high reliability.

Applications/Examples of results
Insulation design for wooden houses (frame construction, metal construction, etc.) including filling between rafters, roof insulation, and sloped ceiling insulation. ZEH, Nearly ZEH, LCCM housing, long-term excellent housing. Insulation performance grade 5, 6, 7 (corresponding to HEAT20 G1, G2, G3 levels).
Detailed information
-
Before the installation of the insulation board "Racty Mp" between the rafters, after the installation of the heat-insulating board "Racty Silver" and the integrated heat-insulating roof panel "HIP Roof."
-
After insulating the gap between the main house and the rafters with one-component polyurethane, "Ractee Mp" is applied.
-
Due to being angled to match the slope, it is lifted and pushed between the rafters and secured to the purlin with a fixing washer. Airtight treatment will be performed from the indoor side.

Our thoughts on home building have not changed over time. We aim to provide a living environment where families can live healthily and happily. The polyurethane insulation panels, which are made with a wooden frame and injected as a single molded unit with minimal aging, ensure insulation and suppress the occurrence of condensation, which is the enemy of homes, thereby creating a comfortable living environment for two or three generations. "To be a home worthy of protecting life." Under this strong belief, we strive to be a leading company in comprehensive insulation manufacturing, starting with polyurethane insulation panels, and contribute to "building homes with high asset value" that become family assets and effective social capital.
