LOW EMISSION GLASS

SOLAR heat gains in wintertime or protection againstheat in summertime

In Winter

Thermal protection is the basic task of glazing units designed for windows. Thanks to our partnership with suppliers, resulting in development of new glass coats, we introduced our brand of low emission glass ECOPANE and ECOPANE PLUS. Now Glass Systems is able to offer glass panes with even lower heat transfer coefficient Ug= 0,4 W/m2K (??? 0,5),. This value is close to the value of heat transfer coefficient of walls. Cold feet near the window are in the past.
All the people who want to save on heating in winter thanks to solar heat gains from the sunlight coming through window panes and are not concerned with overheating in summer, can now purchase heat insulating window panes with increased coefficient g=73%.

In Summer

In summer the sun emits much large quantities of thermal energy, as compared with winter. Overheating is observed, mostly due to heat transfe through window panes. The grade of summer overheating protection is expressed in coefficient g. Its lower value definesbetter efficacy of the protection against overheating. our offer of heat-insulating glass panes includes alsosuch structures that reduce the overheating effect with coefficient g=37%. Today the technology so far reserved for facades can be also be used in all houses. Now everybody can improve their thermal confort while reducing the operating costs of mechanical air conditioning system installed. It is worth to remember that costs of cooling the premises are higher than coscs of heating.

ECOPANE

Glass

Ecopane is Glass Systems branded name for the soft coated low emissivity glass we use. 

The hard coated low emissivity glasses of yesteryear have given way over recent years to the new generation soft coated low E’s, largely due to changes in legislation. These more complex products give much better thermal performance and are a lot more neutral than the hard coast they are replacing – no more unsightly tints on the white net curtains!

THREE times more thermal insulation

than standard double glazing

Sealed units using ECOPANE offer three times as much thermal insulation than standard double glazing and will depending on the window frame, easily exceed the requirements of the latest building regulations, whether by WER or by Overall Window U value route to compliance.

Double glazed units incorporating ECOPANE and having an argon gas filled cavity are some of the best performing sealed units on the market. In a double glazed unit they will have a centre pane U value of 1.20 (??? 1,1), and in a triple glazed unit and this can go down to 0.60 (??? 0,5), U value.

Our Eco PANE glass1.0 range uses a higher specification Low Emissivity soft coat glass that will give a U value of 1.0 in a double glazed and even 0.50 (??? 0,4) in a triple glazed unit.

Optimal temperature in rooms

The level and distribution of air temperatures has a significant impact on our comfort while indoors. Until recently it was possible to feel a dramatic drop in temperature near a window during the winter, which could produce a strong feeling of discomfort. Thanks to the application of thermally insulated glass which amounts to 70% of the window surface it is possible to eliminate this problem the range of temperatures are not subjected to any heat discomfort. A different problem can arise in the summer, when the sun rays overheat the inside of a building. This problem can be rectified by reflexive solar control and selective solar control glass which, thanks to its special construction, limits overheating while maintaining a high level of light transmission. A similar function is also provided by thermal control glass, but to a lesser degree; this is compensated by the benefit of higher heat retention performance during winter that thermal control glass offers.

HIGH LEVEL OF LIGHT TRANSMISSION

One of the particularly important qualitative characteristics of glass is light transmission. This has a particular influence on the well-being of people who use the room in question.
As research shows, poor light transmission into a room can be the cause of a bad frame of mind. PRESS GLASS pays particular attention to this characteristic when preparing a market offer.

REDUCING THE COSTS OF HEATING

Everyone who receives the heating bill wonders about ways to reduce such expenses. At present economizing on heat energy is the main task which faces producers of double-glazed units.
PRESS GLASS perfectly understands these needs and offers a few solutions thanks to which it is possible to significantly reduce the costs incurred when heating a building.

PERFECT heat insulation off glass pane edge

We recommend using warm distance frame bent in corners, acc. to EN ISO 10077, with heat insulating glass panes.
Application of a warm frame improves heat insulating properties on edges, resulting in increase in glass pane temperature in that area and reduction in temporary condensation of vapour.

Argon

Gas

As a double glazed unit is sealed, the space between the two panes of glass is filled with air in order to improve the insulation properties of the unit. Whilst air is considered a good insulator there better options available.

FOR OPTIMUM THERMAL

INSULATION USE ARGON GAS

At Glass Systems we use argon gas as a filler for our insulated glass units. Argon gas is a colourless, odourless and tasteless gas that provides optimum thermal insulation whilst being both non-toxic and inert. Using argon gas in our producst allow them to achieve a higher energy rating compared to units using air.

All of our sealed units hold BS EN1279 Part 3 pass certificates, meaning our sealed units comply with the legal requirements for the testing of rates at hich gas leakes form a unit.

PRODUCTS THAT ARE ENERGY

EFFICIENT FOR NO LONGER

Over time the concentration of gas present within an IGU decreases as it escapes, once the concentration falls below 80% the insulation properties are lost. Even after 20 years a Glass Systems sealed unit will still retain 80% of the argon gas it was filled with during the manufacturing process. This helps to raise the internal glass temperature, eliminating condensation and providing eco-conscious consumers with a product that will reduce their energy consumption, thereby cutting energy costs.

design

One chamber heat insulating glazing unit comprises two glass panes, including one Thermofloat glass pane with invisible layer of inert metals combination (so-called “low emission layer”). Two chamber heat insulating glazing units comprise two Thermofloat glass panes.

The space between glass panes is filled with argon or krypton gas, which further reduces heat transfer coefficient Ug. Protection against gas leak at the glass pane perimeter is ensured by warm distance frame with two-step sealing of plastic.
