The Comparisons between landVac and Brand X
Part I Product Parameter Comparisons at the Same Thickness
| Products /Parameters | LandVac8 | Brand X |
|---|---|---|
| Total Thickness (mm) | 8 | 7.7 |
| Ug (Wim • K) | 0.4-0.5 | 0.7 |
| Light Transmittance (%) | 68-80 | 80 |
| g | 0.58-0.68 | 0.68 |
| Rw [C; Ctr] [dB] | 36 (-2; -3) | 35 (-2; -5) |
| Dimension | Maximum: 1.5m x 2.5m Minimum: 0.3m x 0.3m | Maximum: 1.5m x 2.5m or 1.6m x 2.4m Minimum: 0.2m x 0.2m |
| Shape | Square, rectangle and semicircle | Square and rectangle |
| Laminated Safety Glazing | Available | Available |
Part II What are the Customer's Concerns
| Type | LandVac | Brand X |
|---|---|---|
| Safety | Tempered glass:1r 1. Not easy to break in installation and application; 2. In case of breaking, it becomes small particles with obtuse angles, not easy to injure persons. |
Non – tempered glass: 1. Easy to break in installation and application; 2. In case of breaking, it becomes sharp fragments, easy to injure persons. |
| Warranty | 15 years | 15 years |
| Friendly Enviromental Protection |
1. Comply with EU2015/863 RoHS 2.0
requirements, free of (Cd), (Pb), (Hg), (Cr(VI)),
(PBBs),(PBDEs), DEHP, DBP, BBP and DIBP ; 2. Recyclable |
1. Free of Lead 2. Recyclable |
| Technical Performance | 1. Flexible metal edge sealing: Two panes
of vacuum glass unit deforms quite
inconsistently due to the much higher
temperature difference in cold winter or hot
summer. Flexible metal has great
adaptation and can prevent the glass from
breaking. 2. Double edge sealings can ensure Land Vac units to be used at any places with any environmental conditions. 3. Pillars are placed in 50x6Omm network layout with better view after installation. 4. Its evacuation port makes sure to outgas the residual air completely and maintain its stable vacuum degree for a long time to ensure its longer service life. |
1. Glass edge frit sealing: Two panes of
vacuum glass unit deforms quite
inconsistently due to the much higher
temperature difference in cold winter or hot
summer. The fragility of glass frit makes the
glass easy to break. 2. Single edge sealing. 3. Pillars are placed in 20x2Omm network layout with visual density, easily found after installation. 4. Without an evacuation port, outgassing process is not complete and vacuum degree is difficult to maintain stable for a long time, affecting its service life. |
