Oskura Waterproof is a fully-openable bioclimatic pergola that protects against rain and allows the intensity of natural light to be controlled, above all in summer.

Oskura Waterproof is the only sunshade system fitted with swivelling slats that can be completely folded together electrically, allowing the intensity of sunlight and ventilation to be controlled. When its slats are totally closed, the Oskura Waterproof system guarantees excellent protection against inclement weather and rain, but it can also be totally opened, the only product on the market to offer this triple function.

The Oskura Waterproof system can even be installed on flat structures, without affecting their capacity to give shelter against wind and rain. In the case of solutions complete with a supporting structure, these are made from aluminium profile bars with a broad cross-section. The gutters and drainpipes for rainwater discharge are incorporated in the structure.

Made in extruded aluminium with a broad cross-section and specially shaped forms for their specific applications, and available with anodization in various shades, or painted with polyester powders in the desired colour, resistant to fading over time.

All sliding movements are electrically powered. Every slat runs in its respective guides on silenced ball bearings covered in plastic, and all accessories are made from corrosion-proof materials.

Slats are collected together in a space of about 12% (excluding motor housing).

The extruded aluminium slats contain an insulation material that allows the product to be soundproofed. Slats are also fitted with double waterproofing seals, with lateral channels to drain away rainwater.

Puro is the most innovative and exclusive roofing system for conservatories, solar greenhouses and verandas. The concept of a flat self-supporting roof structure makes Puro a solution without rivals on the market.
With its modern and essential lines, Puro offers a new style of life, dedicating quality spaces and time to your wellbeing.

• Linear design:
  A series of profile bars and accessories that permit the construction of unique roofs with an essential and minimal design.
• Interior/exterior concept:
  The Puro system allows an external glass covering to be created, which can then be finished internally in a variety of different ways. This solution gives a significant reduction in heat loss and excellent control over sunlight.
• Horizontal structure:
  The special horizontal structure of the roof conceals the sloping beams inside it, so that the final internal height is greater than with a classic slanted roof.
• Load capacity:
  The combination of the slim supporting beams and the horizontal profile bars of the frame give structures a high static and dynamic load capacity.

SUNROOM Mod. S.75 TT folding glazed doors are designed and constructed for use in particular in very cold climates, where resistance to harsh weather conditions, sealing and heat insulation are vitally important.
The specifically developed accessories are a perfect complement for the product’s extreme robustness, combining the need to support heavy weights with an innovative and stylish appearance, seen in particular in the hinges and runners in anodized aluminium and stainless steel, and the handles with a square minimalist design.
All components are produced to exclusive TENDER Srl designs with accurately selected materials that are fully tested to guarantee only the best functionality, reliability and duration.

• Fields of application:
  Conservatories, verandas and large sections of opening glazed doors that allow home interiors to communicate with the exterior to create a single environment, business activity, etc.
• Insulation:
  The thermal break in profile bars is composed of 28 mm polyamide bars. The upper and lower tracks and vertical joints form a closed frame, and together with the door panels have double compression seals.
• Dimensions:
  Made-to-measure door panels up to 1200 mm in width and 3000 mm in height. Closures of unlimited length can be constructed by composing groups of door panels running on tracks, with special joints and seals at their meeting points.
• Sliding:
  Door panels slide on two tracks, with runners on the top track and guide rollers on the bottom track. The entire weight of the glazed doors is therefore supported by the floor, avoiding all flexing that could affect perfect movement.
  Two different types of lower track are available, one with a raised edge flap for better insulation and one with a low sloping flap to eliminate obstacles.
• Closure:
  Easy, quick and silent. Door panels can be folded together on the left or right only, or on both sides for larger verandas. The folded doors occupy a space of about 12–13% of their total opened length.

ADJUSTMENTS – Each side upright of the frame consists in 2 profile bars, with several adjustment points easily accessible from the exterior, facilitating installation and making it possible to compensate for any excessive variations due to temperature differences between summer and winter.

GLAZING – Safety glass, double glazing, panels, etc, with thicknesses up to 47 mm.

S.150 TT is an extremely innovative minimal sliding system that uses profile bars with a thermal break of significantly compact dimensions, but with the possibility of fitting double-glazing panels for extremely efficient heat insulation.

The system is made with special profile bars, with a central upright of only 26 mm, offering an almost unobstructed view towards the exterior.
Slim and linear forms, distinguished by exclusive SUNROOM design, offer attractive and original visual results.
All components are produced to exclusive TENDER Srl designs with accurately selected materials that are fully tested to guarantee only the best functionality, reliability and duration.

• Profile bars:
  Profile bars on panels and the frame have a thermal break consisting in 42 mm polyamide bars, giving excellent heat insulation. In addition, their special shape makes maintenance and cleaning of the product particularly easy.
• Sliding:
  Movement on runners with stainless steel wheels sliding on a support also in stainless steel. This system ensures extremely light movement even with particularly heavy glazing panels. The great strength of the runners allows panels with total weights up to 300 kg to be constructed. Every panel has adjustable runners to ensure perfect alignment, which is a special feature on minimal sliding systems of this kind.
• Closures and handles:
  With their square design, Sunroom handles are incorporated in the profile bars of the lateral upright (patented system), allowing them to remain discreetly unnoticeable against the profile bar. On request, closure systems can be fitted with cylinder locks or even security locks.
• Glazing:
  The system can hold glass or other panels up to 48 mm in thickness.
• Types available:
  Frames are made with 2-way or 3-way profile bars to contain 2 – 3 – 4 – 5 – 6 door panels.
• Important features:
  The lower track, with a height of just 23 mm, is usually installed resting on the floor, to ensure excellent results during certification procedures. When necessary to obtain higher sealing performance, a discharge reservoir can be fitted beneath the lower guide.

Tuttovetro Slide is a parallel sliding system, made up of only panels of tempered glass running on upper and lower tracks. This system allows constructions of many types to be assembled, suitable for use in a variety of situations, including verandas and solar greenhouses.
All components are produced to exclusive Sunroom designs with accurately selected materials that are fully tested to guarantee only the best functionality, reliability and duration.

• Fields of application:
  Bioclimatic pergolas, balconies, verandas, solar greenhouses, public venues.
• Accessories:
  All accessories are designed for this specific application. Closures are operated with internal knobs, and are also available with an external key.
  The stainless steel linking system between the glass panels allow all panels to be moved together, without any additional operations.
• Sliding:
  The stainless steel runners have wheels with a diameter of 28 mm and protected ball bearings, with a capacity up to 100 kg for every panel. Every door panel has 2 adjustable runners for perfect alignment. For better operation, panels run on lower tracks covered with stainless steel.
• Glazing:
  The system uses tempered glass panels with thickness of 10 or 12 mm.
• Types available:
  The frame is made up of profile bars for the upper and lower tracks to create from 2 to 7 sliding channels. By allowing all panels to be gathered together next to the first, this system makes it possible to open most of the available surface area.
