BY Slurry-Composite Insulation Board Exterior Wall Fireproof Insulation System (Type II Panel of System A)
An exterior wall fire‑protective insulation system with a fire‑barrier structure, comprising BY insulation boards, fixing materials (adhesive mortar, anchor bolts, etc.), a mortar‑based fire‑resistant leveling layer, a finishing plaster layer, and a decorative finish layer. Type II board‑type panels are produced by using graphite‑enhanced extruded polystyrene boards as the base material; grooves are cut on both sides of the substrate, followed by spraying an interface mortar to form the insulation board.

BY Slurry-Composite Insulation Board Exterior Wall Fireproof Insulation System (Type II Panel of System A)
An exterior wall fire‑protective insulation system featuring a fire‑resistant barrier structure, composed of BY insulation boards, fixing materials (such as adhesive mortar and anchor bolts), a mortar‑based fire‑proof leveling layer, a finishing plaster layer, and a decorative finish layer. Type II board‑type panels are manufactured by using graphite‑enhanced extruded polystyrene boards as the base material; grooves are cut on both sides of the substrate, followed by spraying an interface mortar to produce the finished insulation board.

Scope of Application
It is used as an insulation layer in residential buildings, public buildings, commercial buildings, and for energy‑saving retrofits of existing structures.
Product Advantages
I. Saving Money
The base layer does not require plastering (costing approximately RMB 20 per m²), nor is it necessary to install fire-resistant windows with a fire‑resistance rating exceeding 0.5 hours. Based on current market prices in Linyi, fire‑rated windows cost RMB 650 per m², while standard windows cost RMB 450 per m², resulting in a price difference of RMB 200 per m²; assuming a window‑to‑wall ratio of 1:3 as per contemporary residential design, the additional cost amounts to RMB 66 per m². Furthermore, there is no need to incorporate fire‑break strips, which typically cost about RMB 130 per m². Additionally, the exterior wall substrate does not require an extra two coats of waterproofing—waterproof coating costs roughly RMB 18 per m², and waterproof cement mortar about RMB 25 per m²—yielding savings of approximately RMB 50 to RMB 150 per m².
II. Space Savings
According to the calculation rules for gross floor area in the “General Code for Civil Buildings,” area is measured up to the finish layer. Taking a 100,000-square-meter residential community as an example, reducing the exterior wall insulation thickness by 10 mm can save 600–800 square meters of usable interior space. Under the same energy‑saving standards, when using the same core material, this system is 3 cm thinner than other systems, thereby increasing the net floor‑area ratio. In the expansion project of the West Campus of Linyi No. 4 Middle School, with a total floor area of 85,000 square meters, adopting this system reduced the exterior wall insulation thickness by 30 mm compared with rock wool, resulting in an increase of 1,530–2,040 square meters of usable interior space.
III. Reduction of Construction Period
After implementing this system, the construction process incorporates two waterproofing layers—one rigid and one flexible—eliminating the need for mortar plastering to level the exterior wall substrate and saving the investor and general contractor approximately one month of construction time.
IV. Durable and Reliable
Layer-by-layer gradient and flexible crack resistance: From the insulation layer to the finish coat, the elastic modulus transitions gradually across each layer, effectively eliminating the problem of cracking in exterior insulation systems.
Cavity-free construction: eliminates wind pressure—particularly negative wind pressure—from damaging the insulation layer of high-rise buildings, providing more reliable resistance to wind and seismic forces. It requires no maintenance throughout its service life and has a lifespan equal to that of the building’s structural system.
Instructions for Use
Base wall preparation → Layout of reference lines → Installation of support brackets → Preparation of bonding mortar → Application of the bonding and leveling layer using bonding mortar → Bonding Type II panels and filling joints with a 10–15 mm wide mortar joint → Anchoring with expansion bolts → Construction of a 12–15 mm thick fire‑resistant leveling mortar layer → Preparation of crack‑resistant mortar → Applying the first coat of crack‑resistant mortar and embedding the fiberglass mesh → Applying the second coat of crack‑resistant mortar → Finishing layer construction.
