WOODEN

Terrace windows HS EC 90 is a system of lift and slide
windows characterized by comfortable handling of
very large and heavy sashes (up to 400 kg). HS EC
90 windows have a standard thermally insulated low
threshold, which allows for installation into the floor
and blending with the floor surface

STRUCTURE
single frame terrace window, the leaf thickness 90 mm, frame thickness 210 mm, glazing bead Type C; optionally S-System 

MATERIAL
glued laminated pine wood, optionally oak

FINISH
water soluble covering paints or transparent paints, a three-layer covering system, a four-layer transparent system;

STANDARD OF CONSTRUCTION

• Triple glazed window 4/16Ar/4/16Ar/4 Ug=0,5 W/m2K with warm edge spacer bars
• silicone system seals
• flush top guide bar - no protruding hardware parts in the window lintel
• fibreglass threshold with 15 mm running rail
• handles 

ACCESSORIES AND EQUIPMENT

• glazing units
• espagnolettes with insert
• reed switches
• automatic closing and opening systems
• sash lowering shock absorber - an invisible sash shock absorber reduces the resistance force and causes a gentle return of the handle dedicated to heavy sashes
• Comfort Stop sash damper - brakes the sash during opening and closing just before the end position and gently stops it
• muntins: Vienna bars, on clasps bars, inter-pane bars and structural bars

PARAMETERS

• thermal transmittance*: 0,75 W/(m2K)
