In the hot and humid climate of Southeast Asia, the insulation material selected for Cold room installation directly affects energy consumption, temperature stability and service life of Cold room facilities. Thailand is located in the tropics with high ambient temperatures all year round and large fluctuations in humidity between day and night. Water vapor can easily penetrate the insulation layer, causing insulation degradation and cold loss. This forces compressors to run under heavy load for extended periods and raises electricity bills.
XB Refrigeration Co., Ltd. has years of experience specialising in Cold room installation across Thailand. We undertake various Cold room projects including food cold chains, fruit and vegetable preservation and industrial low-temperature storage. XPS extruded boards are widely adopted in our insulation solutions. With reliable thermal insulation performance, we deliver low-energy and durable Cold room systems for local Thai clients. This article compares key parameters of different XPS extruded board specifications and explains their suitable applications in Cold room projects.
XPS extruded polystyrene foam board, or extruded polystyrene thermal insulation board, is manufactured by heating polystyrene resin and continuous extrusion foaming, forming a closed-cell honeycomb internal structure. This sealed structure endows the board with three core strengths: low thermal conductivity, high compressive strength and low water absorption.
Compared with EPS foam boards and PU polyurethane panels, XPS extruded boards feature superior resistance to water vapour penetration. This makes them well-suited for Thailand’s rainy seasons with high humidity, reducing risks of damp insulation and ageing, and cutting maintenance costs after Cold room installation.
The table below lists three mainstream XPS extruded board types widely used in Cold room installation. It quantifies thermal conductivity, compressive strength, water absorption, recommended thickness and applicable temperature ranges to support early-stage project planning and material selection:
Parameter Item | Standard XPS Extruded Board | Flame-Retardant XPS Extruded Board | High-Density Low-Temperature Special XPS Extruded Board |
Thermal Conductivity (W/(m·K)) | ≤0.032 | ≤0.030 | ≤0.028 |
Compressive Strength (kPa) | 200 | 250 | 350 |
Water Absorption in 72h (Volume Fraction) | ≤1.5% | ≤1.0% | ≤0.8% |
Recommended Thickness for Cold room | 50mm~75mm | 75mm~100mm | 100mm~150mm |
Applicable Temperature Range | Preservation Cold room above 0℃ | Refrigerated Cold room from -18℃ to 0℃ | Quick-freezing Cold room from -35℃ to -18℃ |
Typical Projects | Fruit & vegetable preservation rooms, cool storage rooms | Food Cold room, raw material storage rooms | Seafood quick-freezing rooms, industrial ultra-low temperature Cold room |
Standard XPS extruded boards are cost-efficient insulation materials for Cold room installation, with thermal conductivity ≤0.032 W/(m·K) and compressive strength of 200kPa, meeting normal load requirements for walls and floors.
This material has controlled costs and suits fruit, vegetable and flower preservation Cold room in Thailand, which operate above 0℃ with relatively low cooling demand. Its limitation lies in ordinary flame resistance. It is not recommended for projects with strict fire codes or long-term use below -20℃ for quick-freezing. XB Refrigeration Co., Ltd. applies this board extensively in preservation Cold room for fruit-producing areas in Thailand to balance budget and insulation performance.
Flame-retardant XPS extruded boards are formulated with flame retardant additives. Their thermal conductivity drops to ≤0.030 W/(m·K), while 72-hour water absorption is controlled within 1.0%, balancing insulation, moisture resistance and fire safety.
This board is the primary choice for Cold room installation projects in Thai food processing plants and supporting Cold room for supermarkets that require fire compliance. The recommended thickness is 75–100mm. It stably maintains conventional refrigeration temperature at -18℃, resists vapour intrusion during Thailand’s rainy season and extends the overall service life of Cold room facilities.
High-density low-temperature special XPS extruded board is premium insulation material for Cold room. It features a denser closed-cell structure, thermal conductivity as low as 0.028 W/(m·K), and compressive strength up to 350kPa, offering stronger resistance to heavy floor loads and freeze-thaw cycles.
It is designed for Cold room installation of seafood quick-freezing and food processing Cold room operating between -18℃ and -35℃. A recommended thickness of 100–150mm minimises cold leakage, reduces compressor cycling frequency and delivers long-term electricity savings. It is widely used in high-end Cold room projects for port cold chains and aquatic processing enterprises across Thailand.
Even premium insulation panels depend on construction quality to deliver the expected insulation effect of Cold room installation. When laying XPS extruded boards, staggered joints are required, and gaps must be filled with dedicated insulation sealant to avoid thermal bridges. For Cold room floors, a vapour barrier is installed underneath the boards to block upward moisture from the soil.
Cut edges of boards must be sealed to prevent exposure of foam micropores. During site construction in Thailand, XB Refrigeration Co., Ltd. follows strict procedures of vapour proofing, sealing and staggered laying to prevent insulation failure caused by poor workmanship.
For Cold room installation in Thailand’s tropical humid climate, XPS extruded boards leverage closed-cell structures to achieve low thermal conductivity, low water absorption and high compressive strength, covering preservation, refrigeration and quick-freezing Cold room scenarios. Standard versions focus on economy, flame-retardant panels serve conventional commercial refrigeration projects, while high-density low-temperature grades cater to ultra-low temperature quick-freezing requirements.
Parameter differences among XPS extruded board models affect both upfront investment and long-term refrigeration energy consumption. XB Refrigeration Co., Ltd. develops customised XPS extruded board insulation solutions according to clients’ temperature requirements, load conditions and fire regulations. We provide one-stop services including Cold room design, panel supply, Cold room installation and commissioning in Thailand.
A1: XPS extruded board has lower water absorption, less prone to damp failure in Thailand’s humid rainy season and delivers better floor load-bearing performance.
A2: In Thailand’s tropical climate, high-density XPS extruded board of 100mm or thicker is recommended for -20℃ quick-freezing Cold room.
A3: We operate nationwide in Thailand and provide full-set Cold room design, panel supply and Cold room installation for food factories, aquatic firms and traders.
