Comparing the polycarbonate solid sheet with that of the glass roof
Before the PC Nacelle, the traditional lighting roof was made of glass, but now the endurance plate roof is more and more popular with builders. This change was mainly attributed to the advantages of the endurance plate and the lack of complementary glass lighting.
So, what's the difference between the glass material and the endurance material? Which is better?
Glass lack of light top: easy to break easily fall off. Main reasons: 1. Fixture rust: The steel components that are used to fix the roof of the sky are oxidized and corroded, resulting in the Mu Qing becoming unstable and falling off. 2. Deformation of the frame: The sinking of the house, changes in the temperature difference, its own quality and service life, etc. may cause deformation of the frame, which in turn causes the glass to break or even fall off. 3, silicone aging: bonding silica gel top of the weather will be aging, fatigue, and even failure over time. 4, internal bubbles: If there is bubble inclusions in the top of the glass lighting (such bubbles are often difficult to distinguish the naked eye), received sunlight, the uneven heating effect, easy to burst.
However, endurance plates can better solve the above problems and complement the lack of glass. Mainly reflected in: 1, heat transfer: endurance plate heat transfer is lower than ordinary glass and other plastics thermal conductivity (k value), so that heat loss is greatly reduced, for the construction of warm equipment, is environmentally friendly materials . 2. Impact resistance: The endurance plate is the best one among thermoplastics. The endurance plate made of polycarbonate can maintain good impact resistance over a wide range of temperature for a long time. "Broken glass" and "Ring steel" are the names. 3. Fire-retardant and fire-resistance: The fire-resistance of the endurance board has been tested by the National Fireproof Building Materials Supervision Center. According to the GB standard, the fire-retardant b-class is achieved. The advantages of the plate itself, such as ignition, are ideal for roofing materials.
