acuum insulate glass (VIG) are often employed in buildings
where exists the necessity of reducing the U-value of
the walls, without compromising the amount of sunlight in
the inner spaces. The system is mainly made of two glass
panes spaced through the presence of several support pillars
applied on their surfaces and the insulation performance of
this kind of glazing unit are obtained by removing the filling
gas between the glasses and by creating the vacuum between
them. As consequence, the heat transport due to the presence
of the interposed gas is removed but at the same time, the
atmospheric pressure and the thermal deformations act on the
glass panes by inducing a deflection of the system and stress
on its components (pillars, panes and sealing). In Eensulate
European Project (HORIZON 2020 research program), an
innovative light weight VIG glazing unit has been developed, by
employing a low temperature durable edge seal system based
on polymeric seal materials instead of glass frit. The aim of this
paper is to describe the finite element model of the innovative
system, developed to evaluate its behavior during its operative
condition, considering the thermal expansion and the effect
of vacuum pressure, focusing specifically on the interaction
between glass panes and sealant. In particular, the induced
deflection, the stress on both components and the strain on
the sealant were investigated. In addition, the effects of glass
dimension, temperature difference, type of sealant and sealant
thickness were analyzed, by evaluating the behavior of VIG as
function of the mentioned parameters. Simulations results
were useful to optimize the design of the glazing unit and to
support the choice of the employed materials.
