MARKAL MULTILOCK 4600i2

A pioneering technology, patented in 27 countries, that offers improved energy efficiency and high energy levels

HIGH THERMAL INSULATION

Uf : 1.8 -2.2 W/m2K

Uw* : 1.5 W/m2K with double glazing (Ug: 1.0)

Uw** : 1.5 W/m2K with double glazing (Ug: 1.0)

Uw* : 1.2 W/m2K with triple glazing (Ug: 0.6)

Uw** : 1.2 W/m2K with triple glazing (Ug: 0.6)

 

Three insulation levels:

Optimized foam-filled insulation zone (ELVIAL I2 Technology) that ensures excellent isothermal flow of the window.

Polyamide bars maximum size 24mm with glass fiber re-enforcement 25% (PA6.6 25 GF), for improved insulation and extra rigidity.

Central gasket, glazing gaskets with fins and perimetrical insulation with low density polyethylene, for effective heat transfer minimization.

 

SECURITY

WK2 security level, with up to 21 perimetric locking points.

 

DURABILITY FOR A LIFETIME

Width up to 1.000mm /sash Height up to 2.250mm

Weight up to 90kg /sash Glazing up to 45mm

Perfect functionality:

Customized alignment corners made of polyamide, for extra rigidity of final product.

Corner joints with specially designed recesses to fasten the hinge pins and absorb the glazing weight.

 

ADVANCED SEALING SYSTEM, CONSISTED OF:

EPDM gasket corners for the central gasket, the outer glazing gasket and the perimetric gasket.

Optimized EPDM specimen to connect the Mullion End Cup with the central gasket, for effective watertightness.

Special drainage channels on the frame and on the sash, which prevent water from flowing to the inner part of the profile.

Water tightness result: E900, Ift Rosenheim Germany.
