Insulated glass units

The insulated glass unit is 80% of your window, and because it is so important we propose you get to know few of the glass properties in order to make the most correct choice for glazing your home, office or commercial building.

Different types of glass reach different factor of thermal insulation, noise insulation, sun protection and solidity. No matter of the parameters the glass is absolutely clean and ecological material.

What are insulated glass units?

The insulated glass unit contains two or three glasses, different in kind and thickness, hermetically sealed into a construction. The distance between the glasses is ensured by an aluminium element called spacer, in which an absorbing agent is placed (silicagel) to absorb the moisture. After you choose your combination, the glasses go through a process of cleansing, building of the construction with the spacer and a butyl tape. The construction is hermetically sealed with an insulating material (made of silicone or polyethylene). Then some time is required in order for the insulated glass unit to reach his maximum sturdiness and construction durability.

General and most commonly used insulated glass units come with:

White float glass:

The flat glass is produced with the float glass production process, developed by Pilkington Glass. The melted glass is poured in the end of a bath filled with melted tin. The glass flows over the tin and straightens itself, creating a flat surface on both sides. The glass gets slowly cooled down and hardens while if passes over the melted tin, after which it is taken out of the bath as continuous strip, following this is a process of polishing. Finished product has almost ideally parallel surfaces. Thickness can be 2, 3, 4, 5, 6, 8, 10, 12, 15, 19 and 22 mm.
The standard insulated glass unit contains two white float glasses with 4mm thickness, 16mm spacer between them for ensuring the needed distance and total thickness of the insulated glass unit of 24mm. The thermal transmittance factor is Ug=2.9W/m2/K.

Low emission glass (Ka-glass):

The low emission glass is a high class float glass with pyrolitic (hard) or magnetronic (soft) surfacing. It is installed in the inner side of the window, as a protective layer facing the formed by the two glasses air layer. The surfacing allows for the sun’s short frequency energy to enter the room, but because of its high reflective ability works as an obstruction and stops the leaking of expensive long wave energy as it reflects it back to the room. This way it is preventing energy loss and lowering the heating bills. The insulated glass units built with low emission glasses, lower the energy loss through the window and improve the thermal insulation. Their increased energy efficiency saves up to 40% of the heating expenses during the winter period. They are very suitable for rooms with exposure to the North. The thermal transmittance factor of low emission glass (Ka-glass) with thickness of 24mm is Ug=1,4W/m2/K

High-energy glass (4 seasons):

New concept for insulated glass units, meant for throughout the year comfort. Keeps warm during the winter period, and cool during the summer one. Decreases the loss of heat more efficiently that the traditional high-energy products. Reflects up to 57% of the sun heat through the walls. Energy efficient from the point of view of the lowered need for heating or cooling.
The maximum level of natural light and the low gleaming level ensure high level of visual comfort. Planimeri 4 seasons combines solar control and thermal insulating properties, ensuring comfortable environment throughout the year. It can be used perfectly for winter gardens, windows and facades of living and commercial buildings.
Planimeri 4 seasons is made by application of magnetronic surfacing. It is made out of high quality Planiluks clean float glass, on top of which a layer is applied by magnetronic sputtering into a vacuum (ionic-plasmic sputtering). The produced microscopically thin surfacing effectively reflects the long and short hot radiation waves in combination with low solar factor and thermal insulation. The thermal transmittance factor of insulated glass unit white+4 seasons with thickness of 24mm is Ug=1,4W/m2/K.
This type of glass should always be combined into an insulated glass unit. The surfacing is usually in the inner part (in the chamber) of the insulated glass unit.
During the winter period:
saves energy because of the low need for heating
decreases the condensation of the inner glass
During the summer period:
improves the comfort because of the decreased level of heat
decreases the expenses where there are air conditions used
