The material contains a layer ofheaf-nsulating cotton, which caneffectively block the penetrationof extemal heat and the loss ofindoor cooling,redvce the indoortemperature,and improve energ)efficiency.
The product surface is coveredwith an aniigging transparentlayer,which can effectively resistultraviolet radiation and erosionfrom wind and rain. After 10 yearsof natural exposure, ihe materialremains stable without obviouschanges.
The foamed material inside the board, with its unique closed-cell porous structure,effectively blocks the iransmission of noise, creating a quieter environment for the Space,
The product containswater-repelent foam material,which can prevent the dripping ofcondensation water andeffectively solve the problems ofrot and rust.
Thenonoheat-insulatingcomposite material contained inthe laminated board has excellentproperties such as acid and alkalresisionce ond chemicol medilmresisiance.incorosive-proneenvironments,the service life of thisheat-insulating board is more thanthree times that of color steel tiles.
Thebaseplatecombinesgalvanized steel sheet with rigid{im-coated material. This dualstructure workstogether1oenhance impoctresistance-thesurface layer not onlyresistsimpact and is not easily deformed.but also significantly reduces therisk of surface cracking.
