Our B1 Grade NBR/PVC Foam Board is a high-performance elastomeric insulation sheet designed for B2B building and industrial insulation projects, manufactured by Zhongjia in Guangdong, China with advanced NBR/PVC co-foaming technology. As an Elastomeric Fireproof Foam Board, it features a closed-cell structure with aluminum foil facing, reaching Class B1 fire-proof level and boasting excellent thermal insulation, condensation control and vibration reduction performance. With a density of 35-40kg/m³ and operating temperature of -40°C to +120°C, it is lightweight, dimensionally stable and easy to process, suitable for irregular surfaces and complex insulation designs. Compliant with international green building and fire safety standards, this halogen-free, eco-friendly insulation board effectively solves heat exchange, condensation and noise problems for building envelopes and industrial equipment, making it a core material for B2B insulation projects in construction, manufacturing and environmental control industries.
The integral closed-cell foam structure restricts heat transfer with thermal conductivity ≤0.032 W/(m·K) at -20°C, minimizing unwanted heat exchange between indoor and outdoor environments. It significantly improves the energy efficiency of building envelopes and industrial equipment, reducing long-term operational costs for B2B clients.
With water vapor permeability ≤2.8×10-11 g/(m·s·pa) and vacuum water absorption ≤5%, it completely blocks water vapor penetration. It effectively prevents condensation formation on cold surfaces, eliminating the risk of corrosion, mold growth and surface damage for long-term use.
The rubber-based elastomeric composition delivers excellent flexibility, allowing the board to adapt to uneven and complex surfaces without cracking or shrinking. Its dimension stability ≤10% ensures no gaps form during long-term service, maintaining reliable insulation performance for decades.
As a Class B1 fire-proof insulation board with oxygen index ≥32%, it limits flame spread and produces minimal smoke when exposed to fire. It meets the strict fire safety requirements of public buildings and industrial facilities, protecting personnel and property safety.
Lightweight and easy to cut, shape and bond with standard tools and adhesives, the board enables fast on-site construction with minimal material waste. It is suitable for both new installation and retrofitting projects, improving construction efficiency for B2B construction teams.

Used for wall cavities, ceiling voids and roof insulation, it optimizes the thermal performance of building envelopes, adapting to different climate conditions and supporting energy-efficient building operation.
Applied to cold panels, equipment housings and flat cold surfaces in industrial and commercial facilities, it prevents condensation and moisture damage, extending equipment service life.
Installed as buffer and insulation layers for industrial pumps, fans and compressors, its elastic structure absorbs vibration and reduces sound transmission, improving workshop operational stability and comfort.
Widely used in prefabricated building units and modular industrial equipment, it fits compact designs and irregular surfaces without increasing system complexity, ensuring consistent insulation performance.
Ideal for laboratories, clean rooms and pharmaceutical production facilities, it maintains stable temperature and humidity, supporting precise environmental control for high-standard industrial production.
We provide one-stop customization for B1 Grade NBR/PVC Foam Board to fit all B2B project requirements: customizable length (6m/8m/10m/12m and custom sizes), width (1.5m and extended sizes) and thickness (10mm-30mm). We also offer customized facing materials (aluminum foil of different thicknesses or non-foil options), OEM brand printing and special packaging for bulk transportation. For special working conditions such as ultra-high humidity or extreme temperature, we can adjust the material formula for customized performance. All custom orders, regardless of batch size, are guaranteed with strict quality control and on-time delivery.
Our B2B-oriented after-sales support for NBR/PVC Insulation Sheet includes a 1-year product warranty, covering all manufacturing and material quality issues. We provide professional online technical support for insulation scheme design, on-site construction and product processing, with free technical training for client construction teams upon request. For bulk orders, we offer factory direct delivery and full logistics tracking to ensure on-time project delivery. Our dedicated B2B client manager provides one-to-one service, solving all product-related problems with a 24-hour response time. Long-term cooperative clients also enjoy exclusive benefits such as bulk purchase discounts, priority production and free product testing reports.
