Why LandVac tempered vacuum glazing is a better option than double and triple-insulated glass?
2023-08-21
If you are looking for a high-performance glazing option that can provide excellent thermal insulation, noise reduction, safety and durability, you may consider LandVac tempered vacuum glazing.
LandVac is a safety tempered vacuum insulated glazing that consists of two tempered glass panes(one Low-E and one CLear glass) separated by a vacuum cavity. Unlike traditional double and triple-insulated glass units, which use air or inert gas(usually Aragon) to fill the space between the panes, LandVac uses a vacuum chamber to almost eliminate heat transfer by convection and conduction.
LandVac tempered vacuum glazing has several advantages over double and triple-insulated glass units, such as:
1. Higher thermal insulation: LandVac vacuum glazing has a U-value of 0.4 W/(m2·K), which is much lower than the U-values of double (1.1-2.0 W/(m2·K)) and triple (0.6-0.8 W/(m2·K)) insulated glass units. LandVac can keep the indoor temperature more stable and reduce energy consumption for heating and cooling.
2. Better noise reduction: LandVac has a weighted sound reduction index (Rw) of 39 dB, which is higher than the Rw values of double (28-32 dB) and triple (32-35 dB) insulated glass units. LandVac can block more external noise and create a quieter indoor environment.
3. Enhanced safety: LandVac is a safety tempered vacuum glass that can withstand high impact and pressure without breaking or shattering. In case of damage, LandVac will only form small fragments with obtuse edges that are harmless to humans.
4. Longer durability: LandVac uses low-temperature sealing technology to prevent the vacuum gap from losing its vacuum over time. LandVac also has a high resistance to moisture, which makes it suitable for various applications and environments.
5. LandVac is an ideal vacuum glazing option for heritage projects, refrigeration, skylights, curtain walls and more.
Note: Performance data of double and triple insulated glass are just for reference.
