Corredera Elevable 4600

The Corredera Elevable 4600 it is the system of elevating sliding door with greater thermal insulation of the whole range of sliders with unbeatable transmittance values (UH) that go from 0.8 (W / m²K).

This slide bases its operation on a system in which the leaves are mounted with a mechanism that allows the elevation of the same in the opening maneuver and the descent in the closing, so that the closed door rests on longitudinal seals inferior and lateral, its interlocking being produced in any position and thus improving its sealing and acoustic insulation. It is therefore a robust system in appearance and light at the same time, with an ultra-smooth opening and perfect sliding of leaves by a stainless steel rail that avoids the wear of the piece.

COR 80 Hoja Oculta

The COR 80 Hoja Oculta serial, presents an aluminum hinged system of European Channel with 80 mm depth capable of offering excellent thermal performance without renouncing a minimalist design.

The COR 80 Hoja Oculta has a Uw transmittance index of only 0.8 W / m²K, favored by a break of thermal bridge with 45 mm tubular polyamides and the incorporation of cross-linked polyolefin profiles both in the glass strip and in the interior of the frame and the sheet. Its large glazing capacity of up to 50 mm, enables the use of energy-efficient glasses and the realization of compositions with triple glass and double chamber that reaffirm their thermal performance. This also improves the acoustic insulation, achieving a noise attenuation of up to 46 dB.

All these benefits are reinforced by the great results achieved in the AEV test benches: Class 4 in air permeability, Class E1500 in water tightness and Class C5 in wind resistance.

COR Vision

Cor-Vision is a slide with thermal bridge break with avant-garde design that allows maximum brightness with the minimum aluminum view section.

With its central knot section of only 20 mm, we have the possibility of covering large spans with a minimum profile since its frames, both lateral and upper and lower can be inlayed.


iSlide#neo allows you to have the best views and maximum brightness thanks to its small central section of only 35 mm, the most slender of all PVC sliding systems on the market.
And without giving up the high performance of a good window. The sliding system iSlide#neo allows you to install sliding windows or doors of 2, 3, 4 or 6 sheets thanks to its frames of 2 or 3 lanes, without losing an iota of the interior surface of your living room or room. And all with a pleasant aesthetic thanks to its refined design.
Its capacity to accommodate 24 or 28 mm crystals will allow you to enjoy thermal and acoustic insulation much higher than expected from sliding windows or doors.


Deceuninck, with its new Linktrusion technology, integrates within the main profile alternative solutions to the use of steel reinforcements, which significantly improve the thermal performance and stability of the profiles, guaranteeing perfect rigidity even in large dimensions. The result is a significant improvement in thermal performance and a convincing response to requests from the construction market, towards sustainable products and with guaranteed energy savings. Today Deceuninck presents two solutions. The first: Zendow#neo standard, with a glazing up to 42mm, in which the reinforcements are thermal reinforcements, formed by steel wires combined with cellular PVC. All inclusive and 100% recyclable.
