Cortizo COR 4600 Plus Lift & Slide Exceptional Thermal Efficiency

COR 4600 Plus Lift & Slide

The NEW 4600 Plus Lift & Slide from Cortizo allows for the closure of large openings while ensuring exceptional thermal insulation. Its 80 mm deep sashes and special polyamides enable it to achieve a Uw thermal transmittance of just 0.65 W/m²K, making it one of the sliding systems with the best thermal performance on the market. Furthermore, the perimeter interlock profile is reduced to 120 mm, increasing the glazed surface area and enhancing the entry of natural light into the rooms.

Technical Details:

Transmittance: Uw ≥ 0,65 (W/m²K)

Acoustic insulation: Rw up to 43 dB

Air permeability: Class 4

Water tightness: Class E750

Wind resistance: Class C5

Sections: Frame 180 mm / 280 mm 3 rails / 380 mm 4 rails, Sash 80 mm

Opening possibilities: Sliding 1 rail (1 sash + 1 fixed light), 2, 3 & 4 rails

Glazing: Max. 65 mm, Min. 22 mm

Maximum sash dimensions: (W) 3300 mm, (H) 3300 mm

Maximum sash weight: 400 kg

Characteristics:

Lift & Slide door system that exhibits the best thermal insulation;
Possibility of 90º opening without mullion;
Possibility of large sash dimensions makes this system ideal for enclosing large spaces, at the same time that it provides maximum luminosity;
It is a robust system in appearance, but light at the same time, providing an ultra smooth opening action and perfect sash sliding over a stainless steel rail.

Insulated Glazing.

Triple Glazing Package:

Triple glazing is produced similarly to double glazing but uses three sheets of glass, separated by two Warm Edge spacers. The total thickness of a triple glazing unit is typically 42 mm and is mainly installed in profiles with a minimum construction depth of 70 mm.

Standard / Premium configurations possible:

4S + 4F + 4Lowe + Ar + WE
Neutral Glass SN 70/37 + 4F + 6 Lowe + Ar + WE
6mm SKN 176 II ESG, MCM + 4mm F + WE-N + Laminated 44.2 Lowe, MCM, Ar 90% + pressure valve
4.4.2Lowe + 4F + 4.4.2 Lowe + Ar + WE

Types of glass used in insulated glazing:

Float Glass (clear):

Produced by floating a continuous strip of glass using the “float” technology.
Low-E Glass (low emissivity): A clear, transparent glass coated with a metal oxide film. This film allows light to pass through while reducing heat transfer, thus minimizing heat loss.
Solar Control Glass (4 Season): A flat glass with a special transparent coating. It reflects long-wave infrared radiation and a large portion of solar energy.
Reflective Glass: A monolithic, reflective glass obtained by vacuum deposition using magnetron technology (soft-coat, OFFLINE) or pyrolytic technology (hard-coat, ONLINE).
Ornamental Glass: Features a textured surface, available in a wide range of patterns and colors.
Tinted Glass: Created by adding metal oxides during the melting process, this glass absorbs a significant amount of solar energy, preventing excessive heat entry.
Duplex Glass (anti-burglary / laminated): A laminated glass made by bonding two sheets of float, tinted, reflective, or ornamental glass with one or more layers of polyvinyl butyral (PVB) film. It is available in transparent, colored, or opaque options and is known for its rigidity, adhesion, and elasticity. In the event of impact, PVB films hold the glass fragments together.
Tempered Glass: Treated through a special process to improve surface flexibility. When broken, it shatters into very small pieces, reducing the risk of injury.

Warm Edge Spacer:

Also known as the “warm spacer,” it is used to separate the glass panes in triple or double glazing. This spacer has a significantly lower linear thermal transfer compared to traditional aluminum spacers. Made of a thermoplastic composite material, the Warm Edge spacer is a poor thermal conductor, resulting in more efficient edge insulation.
