Special retractable roof system for snow loads up to 700 kg/m².

The T8000 ER series has been specifically designed for an unprecedented load capacity. It features a new, carefully designed panel profile, tempered insulating glass up to 12-mm thick (per element) and specially reinforced rails.

The perfect solution for areas that experience highland and/or extreme climates (such as the Swiss Alps or Scandinavia), where in some cases snow loads of up to 700 kg/m² can be reached. Conventional retractable roof solutions are not suitable for such high-load values.

In comparison, it can be stated that the panels of the new T8000 ER series are twice as strong as the conventional T8000-series panels, and the reinforced version is up to 4 times better.

Glass panels up to 4-m wide.

In addition, the new T8000 ER is not only suitable for areas experiencing extreme climate.

In more favourable situations, it can cover larger widths with the least amount of intermediate profiles. Thanks to this unique design, glass panels up to 4-m wide can be installed.

Aluminium profile finishes.

The profiles of the T8000 ER retractable roofs can be lacquered in the colours of the Classic RAL range, given an anodised finish or an imitation-wood effect. Choose the perfect finish for your retractable roof.

NOTE: In the case of anodised finish or imitation-wood effect, the steel structures and sheet metal trims will be lacquered in the chosen RAL.

Glass and panels.

Insulating glass

Two or more glass sheets separated by a space that prevents any contact between the glass.

Insulating glass

Insulating glass, also known as double glazing, multiple glazing, or Climalit (trademark), consists of two or more glass sheets separated by a space that prevents any contact between the glass.

The inner space between the glass sheets is usually filled with dry air or other inert gas, but it is also possible to form a vacuum, thus improving their performance. In any case, the spaces are hermetically sealed to prevent air flow and the entry of pollutants.

There are also insulating glasses with special 'very low emissivity' treatments, a transparent metal coating on the inner surface, which provides 50% more insulation than conventional double glazing.

Insulating glass can be combined with other solar control functions, low emissivity, etc.

Insulating glass properties.

If there is a positive aspect to double glazing compared to other glass models, it is the possibility of creating customised glass according to the performance required. Therefore, this type of glass can incorporate heat, acoustic and safety insulation features.

For example: a product with highly beneficial features can be achieved by combining an insulating glass with a low-emissivity and solar control glass all in the same panel, even adding a laminate or acoustic laminate.

In addition, thanks to its space this glass offers very low thermal transmittance and therefore great thermal insulation, which will provide air conditioning savings of over 50%.

Finally, it must be noted that the gas contained in the space will also greatly influence the properties of the glass.

For example: the main objective of the SF6 is to improve the acoustic insulation by reducing approximately 3 dB. Argon, on the other hand, has a low heat conductivity, lower than that of air, which provides greater thermal insulation (reduction of the U value by more than 0.3 W/m²). On occasions, a mixture of two of these gasses is used to achieve specific properties.

Chamber size and energy transmittance.

The thermal transmittance (U-value) in a glass sheet has an inverse relationship to its thickness. The higher the interlayer profile (and therefore the greater the distance between the glass sheets), the lower the radiation transmission (the U-value decreases).

Please note: in spaces greater than 15-18 mm, the air currents created inside them increase energy transmission, so the generic rule referred to here does not apply.

Aluminium profile finishes.


There are 210 shades from the RAL Classic range available for our profiles and accessories.

Beech, pine, oak, tigerwood and sapele are just some of the woods that embellishments imitate with great realism.
