Pre-fabricated Partition Wall

For the patented pre-fabricated partition wall, DANSN adheres to the brand proposition of 'formaldehyde-free, care-free', selects quality and eco-friendly core materials as base materials, and strives to create a comfortable living environment. The overall design of pre-fabricated partition walls is simple and elegant. It greatly raises available space and fully demonstrates the fashionable and avant-garde home decoration philosophy. DANSN formaldehyde-free pre-fabricated partition walls are certified by the CARB-NAF, whose environmental protection standards are higher than the national standards. They have superior fire-resistant, water-resistant, and dampproof performances. The overall sound insulation is 37dB, reaching Grade 1 standards of sound insulation between the outside and rooms specified by the Code for Sound Insulation Design of Civil Buildings (GB50118-2010). They are perfect choices characterized by environmental protection, practicability, durability, and elegant appearance. DANSN provides overall pre-fabricated partition wall solutions to customers like apartments and real estate projects.

Prefabricated Lightweight Partition Wall Construction
1-Acoustic Insulation & Fire-rated Perlite Core

Perlite core material is A1-class fire-rated material, featuring high fire resistance (refractory at 1200°C and above); 7cm thick partition wall can isolate noise of 37dB or higher.

2-Mineral Fiber Frame Core
3-Decorative Face Panel

Adopts a special cement instead of formaldehyde-containing glue as cementitious material, and formed by curing after stirring with perlite, high-strength fiber and other 7 to 8 kinds of functional additives (refractory against temperature above 1200°C)

4-Snap Fastener
Dansn Formaldehyde-free Mineral Fiberboard (Applied to the wardrobe)
1. Mineral Fiber Core

Different from common artificial boards, the mineral fiber core is a mixture of solid wood sawdust, perlite, high-strength fiber, and other 7 to 8 functional additives with a special cement instead of the formaldehyde-containing glue as cementing material.

2. Formaldehyde-free Glue Withstand 4 hours of Boiling Water
3. Two Decorative Surfaces

High-density Fiberboard made with MDI formaldehyde-free glue (Covered by formaldehyde-free furnishing paper)

Other Advantages of the Pre-fabricated Lightweight Partition Wall
High installation efficiency
High installation efficiency

The partition walls can be assembled in three to four hours by two persons, eliminating the wet construction of putty and paint of traditional walls.Hence, construction duration is significantly shortened, while construction efficiency is improved.

Available space is expanded by 10%-15%
Available space is expanded by 10%-15%

The thickness of wall is reduced from 10cm of traditional plaster boards to 7cm of back boards of wardrobes and shoe cabinets used as walls, so available space is expanded.
