Rokwool Sandwich Panel
Best Fire Protection and Acoustic Insulation towards Safe Structures
Rockwool Sandwich panel is developed with greater fire resistance, noise insulation, and thermal insulation. The most secure option among Bangladesh factory, warehouse, and business applications.
Introduction to Rockwool Sandwich Panels
Safety above all in construction. To guard your buildings, workers, and activities from fire hazards, as well as maintain a quiet and power-saving area, Rockwool Sandwich Panels are perfect. They are also referred to as stone wool panels, and they are designed specifically to offer the highest passive fire protection without compromising any insulation.
At Sandwich Panel Technology, we are a premier Rockwool sandwich panel supplier in Bangladesh. We produce the finest-quality panels in the business. Our panels have superior fire resistance, adequate acoustic insulation, and effective thermal performance. This guide is here to illustrate why Rockwool panels are the ultimate choice in safety-focused work.
What is a Rockwool Sandwich Panel?
Rockwool Sandwich Panel is a long lasting building material, made up of three layers
Two Outer Skins (Layers):
These are produced from robust galvanized steel plates covered by a tough color finish coat (PVDF or HDPE). This finish protects it from a form of rust, weather, and mechanical damage.
Inner Core
The inner core is comprised of non-combustible Rockwool (stone wool). The inner core is what provides the panel with its superior fire-resistant and acoustic insulation characteristics.
Consider it as the shield for protection around your building. The steel-facing exterior is strong, and the stone wool core is a formidable fire and noise barrier, earning it the ability to be remarkably effective in producing a comfortable and secure space.
Main Features and Advantage of Our Rockwool Panels
Why choose our Rockwool panels in Bangladesh on your next building project? These are the big benefits
01
Better Fire Resistance (Non-Combust)
The biggest benefit is Rockwool cannot be ignited as it is made from rock. Our panels can withstand rock-solid hot temperatures, easily above 1000°C, and won't melt, burn, or release toxic vapors. This gives persons important time to exit and doesn't allow the fire to spread, saving lives and property.
02
Excellent Acoustic Insulation (Soundproof)
Rockwool is a thick, fibrous insulation that is very efficient in absorbing sound waves. Our panels greatly diminish noise from machines, vehicles, and weather, producing a quieter and more productive space in manufacturing plants, offices, and workshops.
03
Effective Thermal Insulation
Rockwool has good fire safety and, on top of that, provides good heat insulation. This helps it retain consistent room temperatures, thus less energy in cooling and warming, thereby paying less on electricity bills.
04
Water and Moisture Resistant
Our Rockwool panels are hydrophobic, meaning they repel water. This prevents moisture absorption, which inhibits mold growth and maintains the panel's insulating properties and structural integrity over time.
05
High Structural Strength and Durability
Fitted with thick stone wool and robust steel, you get a durable panel capable of withstanding various weights and harsh weather. This guarantees a long lifespan for your building.
06
Environmentally Friendly
Rockwool is made from everyday natural volcano rock and recyclable materials. When its long working life is reached, it can be fully recycled, making it a desirable material on which to build.

Frequently Asked Questions
Are Rockwool panels completely fireproof?
Nothing is absolutely “fireproof,” but Rockwool panels are non-combustible (Class A1). They won’t burn or contribute to the spread of fire, and they make an effective 4-hour fire barrier, depending on how thick they are.
How are they compared with PU panels in fire resistance?
Rockwool panels offer significantly improved fire safety. PU is a Class B fire-retardant, but Rockwool is Class A1, which is as good as it gets.
Can Rockwool panels be dampened?
The all-important material repels water. It won’t absorb moisture, so it’ll remain warm and light even if it gets drenched. This makes it perfect for Bangladesh’s climate.
How long does a Rockwool thermal insulation panel usually last?
They are vastly durable and long lasting, normally over 40 years with low maintenance, as the main material does not rot with age.
Do you provide fire safety certificates?
Absolutely, we can provide you with test reports and certification information on our panels in order to achieve compliance and safety approvals in your building.
