THE RIGHT SPACER FOR EVERY TASK

A Chromatech spacer is more than “just“ a spacer: it is a clumination of years of experience coupled with the latest knowledge and built with an eye for detali, the environment and your needs.
These spacers actively contribute towards less condesation and prodvide an improved indoor climate.

Chromatech spacers provide further advantages:
• 100% recyclable
• 50-70% of raw material made of recycled material
• Reduce CO2 emission
• Probably the most environmentally friendly spacers in the world.

Chromatech spacer

CHROMATECH is the traditional 6.5 mm warm edge spacer in 0.18 mm stainless steel. A classic spacer, which resembles an aluminium spacer in shape and appearance and can be bent in most bending machines for stainless steel.

You will achieve 25-40% less heat loss at the edge of the window as a direct result of a lower heat transfer coefficient and a reduction in thickness - helping keep down heating costs and benefiting the environment.

The unbending facts:
• 6.5 mm warm edge spacer - available in widths from 8-24 mm
• 0.18 mm stainless steel
• 20-40% less heat loss

Chromatech Plus spacer

CHROMATECH plus is made from stainless steel and gives you optimal design and thought-out geometry. The characteristic appearance of the spacer is visible proof of its warm edge.

CHROMATECH plus gives users significantly less heat loss, thanks to the low thermal conductivity and reduced wall thickness. You can achieve 30-50% less heat loss at the edge of the window, and when the internal surface temperature becomes 1-2ºC higher than normal, you minimise condensation and help prevent the resulting damage to the window frame.

The unbending facts:
•    7 mm warm edge spacer with 0.15 mm stainless steel with slots for light refraction
•    30-50% less heat loss at the edges
•    1-2ºC higher surface temperature on the inside of the glass

Chromatech Ultra spacer

CHROMATECH ultra is a modern, warm edge hybrid spacer consisting of hard plastic and a fine, stainless steel structure. The upper, plastic surface is extremely tough and cold-resistant, and it is virtually impossible to dismantle the corners, thus ensuring stability.

The unbending facts:
•    Reduced spacer height: 6.9 mm
•    Low heat loss: Stainless steel 15.0 W/(mK) + top surface in specialist plastic 0.17 W/(mK)
•    Ensures stable corners

Thermal insulation

With the help of modern technologies plain glass (pane) surface is covered with a layer of metal oxides, glass (pane) has much better thermal insulation and remains clear. Oxide covering reflect from 40% to 70% of heat, which conventional glass would conduct.

Heat transfer coefficient is expressed by heat transfer coefficient U - heat transfer through the surface of 1 m2 area of 1 degree Kelvin or Celsius temperature difference between the different sides of the surface (W/m2K). U - is the heat transfer coefficient which shows glass or a glass packet heat loss level. It is expressed by (W/m2K). The lower of U value of the glass or pane packet keeps the heat more efficiently.

Good thermal insulation properties of glass or glass packet are essential not only to preserve heat in the premises, but also for protection against heat. The total energy of sunlight falling through the glass or the pane packet to the premises is described by the factor (g).

The following table presents the individual and glass packet g and U values:

Type of glazing U - heat transfer coefficient (according to EN 673) g - solar factor (according to EN 410)
4mm Planilux 5,8 0,85
6mm Planilux 5,7 0,82

4mm Planilux - 16 (argon) - 4mm Eko plus 1,5 0,69
4mm Planilux - 16 (argon) - 4mm Planitherm 1,3 0,63
4mm Planilux - 16 (argon) - 4mm Planitherm futur 1,1 0,59
6mm Planilux - 12 (argon) - 6mm Planitherm futur 1,3 0,57
4mm Planilux - 16 (argon) - 4mm Planitherm futur N 1,2 0,62
4mm Planilux - 16 (air3) - 4mm Planitherm futur N 1,4 0,62
4mm Planilux -12 (argon) - 4mm Planilux -12 (argon)- 4mm Planitherm Futur N 1,07 0,57
4mm Planilux - 16(argon) - 4mm Planitherm Ultra N 1,1 0,63

It is easy to note that pane packets heat transfer coefficient (U) is much lower than one glass. There are several reasons:
a) Dry isolated chamber in between the panes reduces heat transfer.
b) In chamber between the panes there is low conductivity inert gas (usually argon) that reduces heat transfer.
c) Heat transfer is reduced by radiation, using a special glass with a low permeability (EN) coating (Planitherm Futur (en = 0.033), Planibel Top N (en ≤ 0.04), Planitherm Ultra-N (en ≤ 0.05)).

1 - Frame width (mm).
2 - Filling the chamber between the panes with argon (85% -90%).
3 - Filling the chamber with air between the panes.
