It is a high performance glazing unit that has been designed with an emphasis on achieving gas-tight and structurally sound glazing incorporating warm edge technology.
All components in a high performance Thermobar warm edge insulated glass sealed unit are to be extensively tested and comply with Euro Norm (EN) 1279 Part 2 and 3.
Used to hold glass apart within a sealed unit, spacer tube helps to maintain its structural integrity. Thermobar is a rigid warm edge tube which is made from high performance engineering plastic with a gas diffusion barrier to minimise gas loss from the surface area of the spacer bar.
The composition of Thermobar ensures that it is structurally sound while helping to reduce the heat loss at the edge of the glazing unit.
Decorative grilles can be secured to Thermobar using bespoke solid fixings.
Thermobar is a hollow tube system which means that it can be filled with pure 3A desiccant. This ensures a definitive volume of desiccant in every sealed unit. The sole function of the desiccant or molecular sieve is to absorb any moisture in the airspace and keep the window from misting up in the air space between the surfaces of the glass.
Low-e glass stands for low emissivity glass. This glass differs from normal float glass in that one side of the glass has a special metal coating, technically known as a low emissitivity, or Low-e coating. All energy efficient windows must contain a low-e glass, so insist on it!
The dual sealing system makes up for approximately 90% of the European insulated glass market.
The primary seal serves as a handling aid and as a barrier preventing the ingress of moisture and the loss of energy saving inert gases.
Edge sealants bond to the spacer bar and seal the edge of the sealed unit from moisture ingress and protect the unit from gases passing out of and into the internal unit construction. Options include: Hot Melt, Polysulphide, Silicone and Polyurethane.
The airspace between the glass panes is filled with an inert gas such as Argon. Units filled with an inert gas must meet the requirements to pass EN1279 part 3 standards for gas loss. Thermobar High Performance units are designed with gas-tight properties to meet these standards.
