Glass Wool Board, Rigid A1 Fireproof Thermal Insulation Board for Exterior Wall, Curtain Wall and Machine Room Sound Absorption
1. Product Overview
Centrifugal high-density rigid glass wool is inorganic thermal-acoustic panel refined via mineral melting, centrifugal spinning and compression curing. Rigid and dimensionally steady, it avoids sagging common to flexible glass wool blankets and integrates fireproofing, heat preservation, sound absorption and outdoor durability for exterior walls, curtain walls, equipment rooms and HVAC. Optional single or double-sided aluminum foil, fiberglass or non-woven facings suit indoor fit-out, exterior curtain walls and humid factory environments. Low-formaldehyde makeup, solid structural rigidity and easy field installation make it an ideal eco-friendly insulation for modern green building projects.
2. Core Performance Features
A1 non-combustible all-inorganic panels produce no toxic fumes or molten drips to block flame spread per global building codes. With 0.030～0.040 W/(m·K) thermal conductivity, it reduces HVAC energy loss, while dense micropores cut mid-high frequency noise for offices and equipment spaces. Compression-molded boards stay flat for exposed wall and curtain wall fitting; hydrophobic treatment resists moisture, mildew and aging for harsh environments, and low-formaldehyde composition meets green building standards across residential, commercial and industrial builds.
3. Surface Facing Options
Tailored surface coverings cater to varied construction environments with distinct functional perks.Aluminum Foil Faced Board uses laminated thick foil to boost heat reflection, waterproof, anti-corrosion and scratch-proof traits. It cuts wall and equipment heat loss, matching external curtain walls, exposed machinery, ventilation sections and humid mechanical rooms.Fiberglass Cloth Faced Board owns high tensile and tear-resistant property with superior outdoor weather tolerance against UV and temperature shift damage; it stops fiber fallout and panel cracking, designed for long-term external wall insulation and industrial equipment noise abatement.Non-woven Fabric Faced Board has smooth lint-free surface eliminating loose fiber spillage, perfect for premium interior decoration, ceiling sound absorption, meeting rooms and studios requiring tidy appearance.Unfaced Plain Board is budget-friendly solid compact panel for hidden insulation such as wall cavity filling and enclosed equipment spaces with wide construction adaptability.
4. Standard Technical Parameters
Density options cover 32/48/64/80/96kg/m³ and custom densities available. Regular thickness ranges 25/50/75/100mm with extra custom thickness supported. Standard dimension is 1200×600mm and bespoke sizes acceptable. Fire grade is Class A1 Non-combustible while thermal conductivity stays 0.030～0.040 W/(m·K). Core merits include rigid shaping, deformation resistance, water repellent, low formaldehyde, anti-aging.
5. Main Application Scenarios
External Wall & Fire Insulation works for inner/outer wall thermal coating, curtain wall insulation and fire barrier filling to meet building fireproof and energy-saving criteria.Interior Acoustic Decoration applies to sound-absorbing ceilings, partition infill for offices, meeting halls and audiovisual rooms balancing noise control and interior aesthetics.Industrial Machinery Noise Reduction is installed inside AC, fan and pump rooms plus production workshops to lower operational noise and cut equipment heat waste.HVAC Auxiliary Works provides thermal insulation and vibration damping for ventilation ducts and AC units across commercial and industrial projects.
6. FAQ
Q1: Can this glass wool board pass curtain wall and external wall fire inspection?A1: Sure. Our A1 non-combustible panel is smokeless, toxin-free and drip-proof under fire, blocking flame spread to meet international fire codes for high-rise, curtain wall and fire separation works.
Q2: How does rigid glass wool board differ from flexible glass wool blanket?A2: Raw materials are identical yet structures differ entirely. Rigid boards stay flat and shape-stable for exposed wall, ceiling and curtain wall fitting; rollable soft blankets bend freely for duct wrapping and concealed cavity filling.
Q3: Is rigid glass wool suitable for permanent outdoor curtain wall projects?A3: Definitely. Hydrophobic treatment delivers excellent damp, mildew and aging resistance; foil or fiberglass outer layers further strengthen UV and weather protection to sustain stable insulation, fire and acoustic performance outdoors long-term.
Q4: Do you accept custom-sized orders?A4: We support bulk wholesale plus personalized customization. Standard densities, thicknesses and sizes stay in stock; non-standard dimensions, high-density variants and assorted facings can be produced per project demands.
Q5: Is the board safe for household indoor decoration?A5: Low-formaldehyde eco material emits no harmful volatile gas. Faced variants prevent loose fiber dust, fully compliant for residential interior and enclosed indoor construction.
7. Product Summary
A1 fire-rated rigid glass wool board delivers stable dimension, premium thermal retention and outstanding sound absorption. Outperforming traditional Rock Wool Blanket and foam panels in rigidity, low heat conductivity, weatherproof and eco attributes, it comes with diverse surface facings and full-size customization. Cost-effective for external wall insulation, curtain wall construction, indoor acoustic renovation and industrial equipment energy-saving upgrades.
