Available in black, white and grey, with widths of 18mm, 24mm and 36mm.

The Duplex system delivers enhanced visual depth and improved authenticity compared to standard internal Georgian bars, while benefiting from warm edge spacer technology to support thermal efficiency and condensation resistance.[/nectar_responsive_text][/vc_column][/vc_row][vc_row type="full_width_background" full_screen_row_position="middle" column_margin="default" column_direction="default" column_direction_tablet="default" column_direction_phone="default" bg_color="#ffffff" scene_position="center" top_padding="6%" top_padding_phone="15%" text_color="dark" text_align="left" row_border_radius="none" row_border_radius_applies="bg" row_position_desktop="default" row_position_tablet="inherit" row_position_phone="inherit" overflow="visible" overlay_strength="0.3" gradient_direction="left_to_right" shape_divider_position="bottom" bg_image_animation="none" gradient_type="default" shape_type=""][vc_column column_padding="no-extra-padding" column_padding_tablet="inherit" column_padding_phone="inherit" column_padding_position="all" column_element_direction_desktop="default" column_element_spacing="default" desktop_text_alignment="default" tablet_text_alignment="default" phone_text_alignment="default" background_color_opacity="1" background_hover_color_opacity="1" column_backdrop_filter="none" column_shadow="none" column_border_radius="none" column_link_target="_self" column_position="default" gradient_direction="left_to_right" overlay_strength="0.3" width="1/1" tablet_width_inherit="default" animation_type="default" bg_image_animation="none" border_type="simple" column_border_width="none" column_border_style="solid" column_padding_type="default" gradient_type="default" content_layout="default"][vc_row_inner column_margin="default" column_direction="default" column_direction_tablet="default" column_direction_phone="column_reverse" bottom_padding_phone="15%" text_align="left" row_position="default" row_position_tablet="inherit" row_position_phone="inherit" overflow="visible" pointer_events="all"][vc_column_inner column_padding="padding-4-percent" column_padding_tablet="inherit" column_padding_phone="no-extra-padding" column_padding_position="left-right" column_element_direction_desktop="default" column_element_spacing="default" desktop_text_alignment="default" tablet_text_alignment="default" phone_text_alignment="default" background_color_opacity="1" background_hover_color_opacity="1" column_backdrop_filter="none" column_shadow="none" column_border_radius="none" column_link_target="_self" overflow="visible" gradient_direction="left_to_right" overlay_strength="0.3" width="1/2" tablet_width_inherit="default" animation_type="default" enable_animation="true" animation="fade-in-from-bottom" animation_easing="default" bg_image_animation="none" border_type="simple" column_border_width="none" column_border_style="solid" column_padding_type="default" content_layout="default" gradient_type="default"][vc_column_text css_animation="none" css=".vc_custom_1778672514637{margin-top: 15px !important;}" max_width="550" text_direction="default"]
