Vacuum glazing boasts an insulation performance unrivaled by the conventional glass with its U-value of 0.40 W /m2K and five times stronger strength, not to mention its low CO2 footprint and recyclable nature. Obtain the Best information about Fineo vacuum glazing.
Tempered Vacuum Insulating Glass (TVG) consists of two 4mm-thick sheets of fully tempered glass separated by non-leaded metal seals and an air vacuum space, providing it with slim construction and lightweight characteristics ideal for virtually all glazing systems, window frames, or curtainwall applications.
Rigidity
LandVac Tempered Vacuum Glass is an innovative product that combines the safety features of toughened glazing with performance advantages. All LandVac units contain two 4mm reinforced glass sheets held together by micro support pillars. They are sealed around their edges and equipped with a vacuum chamber in their cavities for added performance benefits.
Designed to form a pressure seal around the edges of the glass, pillars are specifically tailored to create a vacuum-insulated glass unit which reduces contact stress and heat transfer between the insulation surface of the mirror and its frame, as well as being compatible with traditional (and non-traditional) glazing systems for optimal insulation performance and lower energy bills.
The material and geometric properties of vacuum glass panels’ pillars play a crucial role in their dynamic behavior, so in-depth static and dynamic numerical tests were carried out for 101 models to understand changes in geometrical parameters and material characteristics over time. The results are presented here in two categories.
Thermal Conductivity
Thermal conductivity is a primary factor governing temperature gradients of vacuum-tight glass edge seals and ultimately impacts the thermal transmittance (U-value) of triple vacuum glazing. This work developed a new low-temperature composite vacuum-tight glass edge seal using Cerasolzer CS186 alloy and epoxy JB-Weld as sealing materials.
An innovative 3D finite element (FE) model was employed to simulate the thermal performance of triple vacuum glazing with annealed and tempered glass panes using thermal conductivities of Cerasolzer CS186 alloy as a primary seal and JB-Weld as a secondary seal. Simulated results demonstrated a center of glass U-value of 0.33 and overall U-values of 1.05 Wm-2 K-1, respectively.
FEM modeling also examined the effects of widening edge seals on temperature loss transferring from edge to center glazing area, helping reduce the overall U-value to 0.043 Wm-2 K-1 due to reduced temperature gradient from the periphery to central area glazing area.
Low-E Coating
Low-E coatings on tempered vacuum glazing help block solar heat and keep your home cooler during summer. Like how a thermos reflects heat away when hot objects are stored inside and sent back when cold items return, low-E coatings on vacuum glazing help reject solar radiation and keep temperatures lower inside your home during the summer heat.
Attic insulation also protects furnishings from UV light damage that could ruin upholstery and carpets, saving you the hassle of purchasing replacement furniture when damaged.
Low-E coatings can be applied to exterior or interior window panes depending on your application needs and their direction. They work to prevent heat gains from the outdoors or decrease heat loss from within a building, ultimately saving on heating and cooling costs in any climate. For optimal performance, look for products with high solar heat gain coefficient (SHGC) and visible transmittance rating (VT).
Noise Reduction
When it comes to noise pollution in your home, soundproofing glass may be the perfect solution. Blocking out unwanted sounds and helping ensure a good night’s restful rest.
Double-glazed units feature two layers of glass separated by an air space, which buffers noise while still permitting light through.
Glass thickness can impact sound insulation; thicker pieces can reduce noise by more than half; however, this can depend on which type of glass you opt for.
LandGlass introduces its latest generation of vacuum-insulated glass products known as LandVac. This design comprises two pieces of tempered flat glass separated by micro support pillars and sealed around their edges to form an airtight vacuum chamber between them.
