S112 RPT

The best thermal insulation in bi-fold door systems.

Specially reinforced series with thermal break, and four sealing gaskets for the installation of double or triple glazing. It reaches thermal insulation values (Uw) of up to 1.3 W/m²K.

The S112 RPT is a series of specially reinforced bifold sliding doors, with thermal break and four sealing gaskets for the installation of glass with double and triple glazing.

It is the best option for outdoor areas with extreme weather conditions, freezes and strong winds.

Special FOAM bars are placed inside the profiles to provide this series with an unbeatable thermal performance (Uw), reaching values up to 1.3 W/m²K.

It features a retractable central pillar that allows for the manufacture of enclosures larger in size in terms of panel height and width, and it can also incorporate panels up to 3.5 m high and 1.1 m wide.

Features of the S112 RPT bi-fold doors.

Door panels are available with 38 or 50 mm gaps for the installation of glass or panels. Panels can be opened inwards or outwards, and can incorporate one or multiple mullions, with vertical and horizontal glazing beads. 

It can incorporate glass with double and triple glazing. Equipped with vertical and horizontal safety glazing beads that cannot be removed from the exterior.

Available for installation with built-in or overlapping bottom frame; installation with a U-shaped compensation profile is also available to conceal slight unevenness and facilitate installation.

Fittings and accessories.

It can incorporate standard or industrial handles, and multipoint locks; the accessory is available in white, black and, optionally, in the same colours as the profiles. See available fittings and accessories.

Aluminium profile finishes.

The S112 RPT bi-fold door profiles can be lacquered in the colours of the RAL Classic range, or given an anodised finish or an imitation-wood effect. This series can have a two-colour finish, both for lacquered and anodised finishes*. Choose the finish for your bi-fold doors.

* The two-colour finish option is only available for high-volume orders.

Glass and panels.

Insulating 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.

Sandwich panel

Sandwich panel

Our roofs enable the installation of totally opaque and highly resistant aluminium plates or sandwich panels. These plates are composed of three sheets: thermo-lacquered aluminium sheets with different finishes (RAL coatings, anodised or wood) that are placed on the inside and outside, and an extruded polystyrene core of great resistance to compression that provides excellent thermal insulation.

Sandwich panel properties.

Lightweight structure with high impact resistance, manufactured in different thicknesses according to insulation needs. It also comes in a great variety of finishes, although light colours on the outside are always recommended for greater durability.

Perfect for applications in which a totally opaque enclosure is required, blocking out incoming light when it is closed. Once the system is opened, light is allowed back in.
