PRR Line Board

Article 6.7.12 of the “Code for Fire Protection Design of Buildings” GB 50016 – 2014 (2018 Revised Edition) states that the decorative layer of the building exterior wall should adopt materials with a combustion performance of Class A. However, when the building height is not more than 50m, Class B1 materials can be used. This requires that the decorative profiles for exterior wall insulation must simultaneously consider both fire protection and insulation functions. In buildings designed with a Class A exterior wall insulation system, once a large number of decorative profiles are involved, design units usually require the use of decorative profiles with a Class A fire protection performance. The most common EPS decorative profiles now face limitations in terms of building height and combustion performance. Among Class A fire – rated inorganic insulation and decorative materials, vertical – filament rock wool is gradually coming into the public eye.

Based on this technical background and market demand, the company has developed and launched vertical – filament rock wool profile boards with a Class A fire rating, which can simultaneously meet the functional requirements of insulation, heat insulation, sound insulation, waterproofing, and beautification. This product works best when used in conjunction with the Wanhua PRR board thin – plastering system.

This decorative profile not only has an exterior wall decoration effect but also features a Class A fire rating, good insulation effect, high tensile strength, high compressive strength, excellent crack – resistance, and a long service life.

PRR profile boards adopt advanced domestic continuous production processes and are pre – fabricated in the factory. The entire production process is under real – time dynamic monitoring, ensuring stable and controllable product quality. The production efficiency is 10 times higher than that of traditional production processes.

It is commonly used in the PRR board thin – plastering system and adopts the “adhesion + anchoring” process for double – layer protection.
It can be directly wet – pasted on – site, which is convenient for installation. The finish coating can be directly applied on the outer surface of the profile. The construction operation is simple, ensuring that the exterior wall of the main building does not have cold or hot bridge effects.
