Formaldehyde-free Glass Wool | Class A Non-combustible Thermal Insulation, Sound Absorption & Fireproof Material
1. Product Overview
This formaldehyde-free glass wool is made of high-quality mineral raw materials. The main materials include quartz sand, dolomite and soda ash. We use eco-friendly adhesive without formaldehyde. The product is made through high-temperature melting and centrifugal blowing processes.We do not add any formaldehyde in all production steps. No formaldehyde can be detected from finished products. It is a soft inorganic fiber insulation material.
This product has good heat insulation effect, strong sound absorption ability and Class A fireproof performance. It also resists moisture well. It is light and soft, and easy to cut on site. It produces little dust during construction. It is widely used for indoor decoration, air-conditioning ducts, public buildings and industrial equipment. It is a safe green insulation material for green buildings, hospitals, schools and nursing homes.

3. Core Product Advantages
No formaldehyde, eco-friendly and safe for indoor use
This product uses formaldehyde-free glue. It releases no harmful volatile gas and has no sharp smell. It is safe for long-time indoor use in houses, kindergartens, schools, hospitals and nursing homes. It meets strict indoor environment inspection standards for high-end decoration and green buildings.
Class A fireproof material for safe fire prevention
This inorganic fiber material will not burn. It will not help fire spread, and will not produce toxic black smoke when heated. It can block fire and heat transfer effectively. It fully meets national building fire protection requirements.
Low heat conduction value, save building energy
Its porous internal structure locks still air inside. It slows down heat transfer. It blocks outdoor heat in summer and keeps indoor heat indoors in winter. It reduces energy use of air conditioners and heating equipment greatly.
Good sound absorption effect, quiet indoor space
The staggered fiber pores can absorb medium and high frequency noise effectively. It reduces indoor echo and air duct noise. It makes indoor space quieter and more comfortable.
Resist moisture and mold in humid environment
It has high water repellent rate. It will not absorb water, harden or grow mold in wet places. Most insulation and sound absorption performance can recover after natural air drying. It keeps stable performance in damp working conditions.
Light weight, easy installation and less construction dust
The material is soft and light. Workers can cut it freely according to site size. It produces less dust than rock wool during construction. It can fill gaps or wrap ducts easily for ceilings, partition walls and ventilation pipes, and improves construction efficiency.
Stable physical and chemical performance, long service life
It can resist acid, alkali, aging and bacteria growth. It will not drop powder, shrink or deform after long-time use. It needs little later maintenance and cuts overall project cost.
4. Application Scenarios
HVAC Systems: Insulate heat and reduce noise for air ducts and cold/hot pipelines. It also prevents pipeline condensation.
Interior Decoration: Heat insulation and sound absorption for partition walls and ceiling gaps of houses, offices and hotels
Public Venues: Fireproof, heat insulation and sound absorption for schools, hospitals, stadiums and exhibition halls
Industrial Projects: Insulation for factory equipment, storage tanks and medium-low temperature pipelines; noise reduction for equipment rooms
Steel Structure Buildings: Heat insulation for steel structure roofs and wall interlayers
Transportation Interiors: Insulation and sound absorption for rail transit vehicles, ships and containers
5. Construction Guidelines
Keep the base surface flat, dry and smooth. Remove sharp protrusions to avoid damaging glass wool fibers.
Cut materials according to actual site size. Make sure all joints are closely spliced without gaps.
Wrap pipelines completely during construction. Press lap joints tightly to avoid heat leakage.
Lay waterproof and moisture-proof barrier layers for outdoor sites and high-humidity environments.
Wear gloves, masks and protective goggles during construction. It can prevent fiber from irritating skin and respiratory tract.
6. FAQ
Q1: Can this product be used for bedroom and children's room decoration?
A1: Yes. It has no formaldehyde and no bad smell. It is eco-friendly and fully suitable for indoor home decoration with high environmental requirements.
Q2: Can this glass wool pass project fire inspection?
A2: Yes. It reaches Class A non-combustible standard. It fully meets national fire protection codes for project acceptance.
Q3: Will wet environment affect its insulation performance?
A3: It has strong water repellency. It hardly absorbs water under normal humid conditions. Serious damp will slightly lower its insulation performance, but most performance can recover after air drying. We suggest laying moisture barrier layers for long-term wet environments.
Q4: How to choose suitable density?
A4: Choose 24-48kg/m³ for common building insulation; choose 48-80kg/m³ for noise reduction projects; choose density above 80kg/m³ for medium and high temperature industrial pipelines.
7. Product Summary
This formaldehyde-free glass wool meets national standard GB/T 13350-2018. It has seven core advantages: zero formaldehyde emission, Class A fireproof performance, efficient heat insulation, good sound absorption, moisture resistance, easy installation and long service life. It fixes many shortcomings of traditional insulation materials. It has complete specifications and simple construction steps. It is the preferred inorganic insulation material for green building projects, indoor decoration and HVAC fireproof and noise reduction projects.
