PN4R-01
- Description
Soundproof and heat-insulating foam sheet PN4R-01 4 grooves - monochrome white - matte surface
PN4R-01 4-groove soundproof and heat-insulating foam sheet with white monochrome matte surface is a new generation material, perfectly combining effective insulation technology and superior soundproofing ability, providing optimal solutions for modern construction works such as warehouses, factories, prefabricated houses, assembled houses, industrial parks.
What are the structural layers of the PN4R-01 insulation panel?
PN4R-01 insulation panel consists of 3 main layers:
- The surface layer of PN4R-01 corrugated iron is made of aluminum-zinc alloy coated steel sheet (coating layer: 55% Al + 43% Zn + 2% additives) + Nippon paint coating. This aluminum-zinc alloy coating technology provides good corrosion resistance, no rust for 45 years.
- Polyurethane Foam (PU) core layer is the key factor that creates the insulation and soundproofing ability of PN4R-01 foam panel. High density PU foam has low thermal conductivity coefficient λ = 0,022-0,028 W/mK, providing a comfortable space for users.
- The silver-coated fiberglass fabric on the bottom plays an important role in enhancing the structure and durability of the material.

Outstanding features of 3-layer insulation panel PN4R-01 4 white grooves
PN4R-01 insulation panel is an effective solution for outstanding construction with sound insulation, anti-corrosion and load reduction capabilities.
- Effective noise reduction, creating a quiet space: The sound insulation ability of PN4R-01 foam sheet is good at 35-40dB. With high density PU foam layer, the sound insulation material is effective against all types of machinery and industrial noise.
- Anti-corrosion and rust, durable over time: The surface of the panel is coated with a layer of aluminum-zinc alloy, creating a solid protective barrier that is rust-free for 45 years and has a lifespan of more than 20 years.
- Reduce construction load, optimize construction costs: With an effective size of 380 x 16 x 2900mm, PN4R-01 foamed corrugated iron is optimally designed for fast construction and minimal joints. The material weight is only 3,7kg/m², 60-70% lighter than traditional bricks and tiles, helping to effectively reduce the load on the construction.
Diverse applications of 3-layer insulated foam panel PN4R-01
Kosmos warehouse is currently distributing 3-layer insulated foam panels PN4R-01 to many agents nationwide. This material is popular:
- Applications in civil works (houses, villas, townhouses): Helps reduce the temperature inside the house, especially in hot summer, creating a cooler space and reducing noise from falling rain and traffic outside, bringing quietness to the resting space.
- Applications in industrial and commercial buildings (factories, warehouses, freezers): Helps maintain a stable internal temperature, protecting machinery, equipment and goods from being affected by excessive heat. At the same time, the material also creates a more comfortable working environment for workers.
PN4R-01 4-groove white, matte-surface soundproof and heat-insulating foam sheet is a smart choice for all projects, a perfect combination of advanced technology, efficiency and sustainable value, fully meeting modern construction needs.
