    Product Description

    4mm Toughened Ultra Clear Float Glass for Glass Greenhouse
     

    Ultra Clear (Low Iron) Float Glass for Glass Greenhouse Roofs and Side Walls
    Thickness: 4mm
    Glass Grade: Fully-Tempered Glass
    Applications:  Roofs of greenhouse projects
                           Side walls of greenhouse projects


    Glass Features
    1.  MIGO Ultra Clear Float Glass is a kind of extra clear low iron float glass with light transmission higher    
         than 91%. Its high performance stability and good processability make it one of the best choices as the glass        greenhouse roofs and walls.    .
    2.  MIGO Ultra Clear Float Glass offers superior solar energy transmittance and is stable under solar
         radiation. It also survives harsh environmental conditions and protects your crops and flowers from heavy  
         wind, rainstorm, snowstorm, hail, tornado, and etc.
    3.  MIGO Ultra Clear Float Glass is fully tempered as per EN12150, 4-5 times stronger than annealed glass with
         the same thickness.
    4.  Anti-reflective coating can be deposited on one or two glass surfaces to increase light transmittance by ≥ 2%.
