New Polyurethane Sealed Edge Fiberglass Foam Sandwich Panels
Polyurethane-edged Fiberglass Foam Sandwich Panels are recognized as a better steel building enclosure fire insulation board. It has low thermal conductivity, good load resistance, high bending strength, non-absorbent, non-rotting, non-insect and rodent biting, good flame retardant, high fire rating, and extensive temperature range.
Using the physical properties of polyurethane and its unique formula, the polyurethane foaming agent is evenly sprayed on the color-coated steel plate so that the foaming agent is foamed and molded between the color-coated steel plates to become a three-layer, one-time molding of pir color-steel composite sandwich panels. This new light-building material is the perfect combination of color-coated steel plate and polyurethane, which is the development direction of light-building material.
Performance characteristics
Sealing performance
The polyurethane double-sided sealing Fiberglass Foam Sandwich Panels adopt an assembly-line production process, thus utilizing the excellent waterproof property of polyurethane products to overcome the shortcomings of glass wool, which is easy to absorb water and moisture decomposition. This effectively prolongs the service life of the product in terms of physical properties.
Aesthetic performance
The interface is designed according to European standards, with a rounded and smooth appearance, a flat and beautiful board surface, tight seams, reliable strength, and effective prevention of hot and cold bridges.
Good stiffness
Polyurethane double-side seal glass wool core material and two layers of steel plate bonded into a whole, working together, coupled with the roof panel on the surface of the wave pressure; its overall stiffness is far better than the pressurized plate clamped glass wool on-site composite panels. The sandwich panel is fixed with purlin through connectors, which significantly improves the overall stiffness of the roof and strengthens its overall working performance. The selection of New Polyurethane Sealed Edge Fiberglass Foam Sandwich Panels can use a more considerable purlin distance, saving purlin dosage 1/3 ~ 2/3.
Reasonable Buckling Method
Polyurethane double-sided sealing is a reasonable buckling method. New polyurethane-sealed edge fiberglass foam sandwich panels adopt concealed buckling connections, avoiding the hidden trouble of water leakage in roof panel joints and saving several accessories.
Firm and reasonable fixing method:
The polyurethane double-side seal glass wool sandwich panel is fixed with the purlin by special M6 self-tapping screws, which can effectively resist external forces such as typhoons. The self-tapping screws are set in the crest position between the two board joints of the roof panel, and unique waterproof construction is adopted to avoid the waterproof weak points.
Short installation cycle
Due to their scene without secondary processing, polyurethane double-side seal fiberglass foam sandwich panels not only maintain the cleanliness of the surrounding environment and do not affect the normal conduct of other processes but also significantly shorten the installation cycle of the plate, glass wool sandwich panels, and glass wool sandwich panels, with an average daily installation area of 600-800m2.
Anti-scratch protection
Polyurethane double-sided seal frp sandwich panels can be pasted on the surface of the polyethylene self-adhesive protective film during production to avoid the transportation and installation process of the steel plate surface coating scratching or abraded.
Advantages
Excellent fire performance:
Polyurethane double-sided seal frp sandwich panels use raw materials, production processes, and formulations with very good fire performance. Tests show that it has a fire resistance of more than 1000 ℃. The polyurethane double-sealed glass wool sandwich panel has passed the test of GIOROANO S.P.A., an authoritative Italian testing agency. According to the standards of the International Organization for Standardization (ISO), British BS, and German DIN, the glass wool sandwich panel meets the requirements of fire resistance standards M.I. 14/09/61 letter No. 91 and D.M. 30/11/83. The test results are as follows: 50mm thick polyurethane double-side sealed glass wool sandwich panel EI30, 80mm thick polyurethane double-side sealed glass wool sandwich panel R.E.I. 60, 100mm thick polyurethane double-side sealed glass wool sandwich panel REI 120.
Good thermal insulation
Polyurethane double-side seal Fiberglass Foam Sandwich Panels thermal insulation is based on the thermal conductivity of glass wool λ=0.043 W / m2 K based on the corresponding proportion of the thickness of the glass wool core material calculated.
The sound insulation and sound absorption effects are remarkable:
Polyurethane double-sided seal glass wool sandwich panels significantly reduce noise transmission and are especially suitable for designated flights throughout the place. In addition, after using glass wool roof panels, rain and hail on the building's roof steel plate were caused by indoor sound, but they were also significantly reduced.
Through the test, according to ISO717/82 and UNI 8270/7 standards, the density of 120kg/m3 glass wool as the core material of the sandwich panel, the sound insulation effect can reach R.W. = 29 ~ 30 dB. glass wool sandwich panels at the same time has a very good sound absorption effect, it can absorb a wide range of frequency range of sound. According to ISO 354/85 standard, Fiberglass Foam Sandwich Panels' sound absorption performance level reaches DELTA LA=15.7 dB(A).
Polyurethane double-side sealed frp sandwich panels give full play to the unique properties of glass wool core material, fire prevention, thermal insulation, sound absorption, and sound insulation, etc., has a significant effect; at the same time, retained the polyurethane plastic, airtight, high strength, non-absorbent advantages.
Introducing this material is a revolutionary change in construction engineering. The advantages of polyurethane and glass wool have been fully integrated, discarding the shortcomings of traditional panels. In a sense, polyurethane double-seal Fiberglass Foam Sandwich Panels and ordinary glass wool sandwich panels can not be compared.
