Instead of simply adding another pane of glass, C.U.in uses two panes of glass with a virtually invisible suspended film between them. This creates two insulating cavities, helping achieve the thermal performance associated with high-performance triple glazing while reducing the additional thickness and weight of traditional triple glazed glass. For replacement windows, retrofit glazing and new window systems, this gives installers another way to achieve demanding U-values without automatically moving to a thicker, heavier conventional triple glazed unit.[/vc_column_text][divider line_type="No Line" custom_height="1vw"][nectar_cta btn_style="arrow-animation" heading_tag="h4" link_type="image_lightbox" button_color="default" button_color_hover="#da2c46" text_color="#da2c46" text_color_hover="#ffffff" button_border_color="#da2c46" button_border_color_hover="#da2c46" button_border_thickness="1px" alignment="left" alignment_tablet="default" alignment_phone="default" display="block" display_tablet="inherit" display_phone="inherit" link_text="Get a C.U.in Trade Quote" url="mailto:info@crystalunits.com" margin_top="30" padding_top="20" padding_right="40" padding_bottom="20" padding_left="40"][/vc_column][vc_column column_padding="no-extra-padding" column_padding_tablet="inherit" column_padding_phone="inherit" column_padding_position="all" flex_gap_desktop="10px" 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="1/6" tablet_width_inherit="default" animation_type="default" bg_image_animation="none" border_type="simple" column_border_width="none" column_border_style="solid"][/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="#0a1c2d" scene_position="center" top_padding="8%" constrain_group_1="yes" bottom_padding="8%" text_color="light" 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" shape_type="straight_section" gradient_type="default"][vc_column column_padding="padding-2-percent" column_padding_tablet="inherit" column_padding_phone="inherit" column_padding_position="all" flex_gap_desktop="10px" 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="1/2" tablet_width_inherit="default" animation_type="default" enable_animation="true" animation="fade-in" animation_easing="default" bg_image_animation="none" border_type="simple" column_border_width="none" column_border_style="solid"][divider line_type="No Line" custom_height="40px"][split_line_heading line_reveal_by_space_text_effect="default" font_style="h3" text_color="#da2c46" stagger_animation="true" font_size_max="90px" content_alignment="default" mobile_content_alignment="inherit" animation_type="line-reveal-by-space" link_target="_self" text_content="Why C.U.in" font_size="4vw" font_size_phone="3em" font_line_height="1.2" font_size_tablet="7vw" text_direction="default"][/split_line_heading][divider line_type="No Line" custom_height="40px"][nectar_icon_list color="default" direction="vertical" icon_size="small" icon_style="border"][nectar_icon_list_item icon_type="icon" text_full_html="html" title="List Item" id="1789135697525-8" tab_id="1789135697525-3" icon_fontawesome="fa fa-plus" header="Triple Glazing Performance, Without Three Panes of Glass"]Traditional **double glazing** uses two panes of glass with a single insulating cavity. Conventional **triple glazing** adds a third pane of glass to create two cavities and improve thermal performance. C.U.in takes a different approach. A virtually invisible suspended film is positioned between two panes of glass, dividing the unit into two insulating chambers. This allows C.U.in to deliver **triple glazing levels of thermal performance without the weight of a third pane of glass**. For window installers and manufacturers, that can mean: - Lower U-values - Reduced glass weight compared with conventional triple glazing - Slimmer IGU configurations - Easier integration with suitable double glazed window systems - Less need to move to deeper, heavier triple glazing systems - Greater flexibility for replacement and retrofit projects [/nectar_icon_list_item][nectar_icon_list_item icon_type="icon" text_full_html="html" title="List Item" id="1789135697530-6" tab_id="1789135697531-10" icon_fontawesome="fa fa-minus" header="Slim Enough for Many Double Glazed Frames"]One of the biggest challenges when upgrading from **double glazing to triple glazing** is the additional thickness and weight of the triple glazed unit. Existing window profiles may have been designed around standard double glazed units, making conventional triple glazing difficult or impractical without replacing the complete window system. C.U.in can provide an alternative. Its suspended film creates the additional insulating chamber without requiring a third pane of glass, allowing certain C.U.in configurations to achieve **triple glazing performance within dimensions suitable for many existing double glazed frames**. The existing frame, glazing rebate, unit thickness, glass specification and application should always be checked before manufacture. Crystal Units can help determine the correct specification for each project.[/nectar_icon_list_item][nectar_icon_list_item icon_type="icon" text_full_html="html" title="List Item" id="1789135697534-9" tab_id="1789135697535-0" icon_fontawesome="fa fa-sort-desc" header="Low U-Value Double Glazed Construction"]C.U.in combines the practical construction of a two-pane insulating glass unit with thermal performance that can exceed many conventional double and triple glazing configurations. Depending on the specification, C.U.in can achieve U-values as low as **0.4 W/m²K**. For installers, this opens up new options when customers or project specifications require better thermal performance but conventional triple glazing isn't the most practical solution.[/nectar_icon_list_item][nectar_icon_list_item icon_type="icon" text_full_html="html" title="List Item" id="1789135697536-8" tab_id="1789135697536-9" icon_fontawesome="fa fa-lightbulb-o" header="Lighter Than Conventional Triple Glazing"]With conventional triple glazing, improved insulation comes from adding another pane of glass. That additional glass increases the overall weight of the IGU, which can affect window hardware, frame requirements, transportation, handling and installation. C.U.in replaces that third pane with an ultra-light suspended film. The result is a **high-performance insulating glass unit with two panes of glass and two insulating cavities**, delivering advanced thermal performance with less glass than a traditional triple glazed

technology with argon-filled cavities to achieve a **typical U-value of 0.7 W/m²K**. It provides a strong option for installers looking to upgrade the thermal performance of traditional double glazing without automatically moving to a conventional three-pane triple glazed unit. Its relatively slim construction means it can be suitable for many window systems originally designed around double glazing, subject to the existing frame, glazing rebate and required IGU specification. For replacement glazing, this can provide a practical route towards **triple glazing performance from a slimmer, lighter glass unit**.[/vc_column_text][divider line_type="No Line"

The complete IGU specification, U-value, unit thickness, glass weight, frame system, solar performance and application all need to be considered. **Double glazing** provides a practical solution for many standard window applications but may not achieve the low U-values required for more demanding projects. **Triple glazing** can improve thermal performance by adding a third pane and second cavity, but this also increases the thickness and weight of the glass unit. **C.U.in** creates two insulating cavities using a suspended film rather than a third pane of glass. This provides installers with a route to advanced **triple glazing thermal performance from a slimmer, lighter IGU construction**. Crystal Units can help you compare the options and specify the right glass for the window system rather than simply manufacturing whatever is ordered.[/vc_column_text][/vc_column][vc_column column_padding="no-extra-padding" column_padding_tablet="inherit" column_padding_phone="inherit" column_padding_position="all" flex_gap_desktop="10px" 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="1/6" tablet_width_inherit="default" animation_type="default" bg_image_animation="none" border_type="simple" column_border_width="none" column_border_style="solid"][/vc_column][/vc_row][vc_row type="full_width_background" full_screen_row_position="middle" column_margin="custom" column_margin_custom="5%" column_direction="default" column_direction_tablet="default" column_direction_phone="default" scene_position="center" top_padding="5%" bottom_padding="1%" top_padding_phone="20%" constrain_group_5="yes" bottom_padding_phone="20%" left_padding_phone="0" right_padding_phone="0" 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" shape_type="" gradient_type="default"][vc_column column_padding="no-extra-padding" column_padding_tablet="inherit" column_padding_phone="inherit" column_padding_position="all" flex_gap_desktop="10px" 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="5px" column_link_target="_self" column_position="default" gradient_direction="left_to_right" overlay_strength="0.3" width="5/6" 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" offset="vc_col-xs-12"][vc_column_text css="" text_direction="default"] ###### TRIED AND TESTED [/vc_column_text][split_line_heading line_reveal_by_space_text_effect="scroll-opacity-reveal" font_style="h3" text_color="#000000" stagger_animation="true" font_size_max="90px" content_alignment="default" mobile_content_alignment="inherit" animation_type="line-reveal-by-space" link_target="_self" text_content="Independently Studied Thermal Performance" font_size="4vw" font_size_phone="2em" font_line_height="1.2" font_size_tablet="7vw" text_direction="default"][/split_line_heading][divider line_type="No Line" custom_height="3vw"][vc_column_text css="" text_direction="default"]C.U.in suspended film technology has been independently studied against conventional **double glazed and triple glazed units**. The independent white paper assessed thermal performance, energy demand and embodied carbon across different glazing configurations and building scenarios. Testing included a **36mm C.U.in unit with a centre-pane U-value of 0.4 W/m²K**, compared with a typical 28mm double glazed unit at 1.0 W/m²K, a corresponding 36mm triple glazed unit at 0.9 W/m²K and a typical 50mm triple glazed unit at 0.6 W/m²K. This demonstrates why C.U.in can be particularly valuable where installers need **high-performance triple glazing results without the thickness and weight associated with a conventional three-pane IGU**.[/vc_column_text][divider line_type="No Line" custom_height="1vw"][/vc_column][vc_column column_padding="no-extra-padding" column_padding_tablet="inherit" column_padding_phone="inherit" column_padding_position="all" flex_gap_desktop="10px" 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="1/6" tablet_width_inherit="default" animation_type="default" bg_image_animation="none" border_type="simple" column_border_width="none" column_border_style="solid"][/vc_column][/vc_row][vc_row type="full_width_background" full_screen_row_position="middle" column_margin="custom" column_margin_custom="5%" column_direction="default" column_direction_tablet="default" column_direction_phone="default" scene_position="center" top_padding="1%" bottom_padding="5%" top_padding_phone="20%" constrain_group_5="yes" bottom_padding_phone="20%" left_padding_phone="0" right_padding_phone="0" 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" shape_type="" gradient_type="default"][vc_column column_padding="no-extra-padding" column_padding_tablet="inherit" column_padding_phone="inherit" column_padding_position="all" flex_gap_desktop="10px" 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="5px" column_link_target="_self" column_position="default" gradient_direction="left_to_right" overlay_strength="0.3" width="5/6" 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" offset="vc_col-xs-12"][split_line_heading line_reveal_by_space_text_effect="scroll-opacity-reveal" font_style="h3" text_color="#000000" stagger_animation="true" font_size_max="90px" content_alignment="default" mobile_content_alignment="inherit" animation_type="line-reveal-by-space" link_target="_self" text_content="More Than a Double and Triple Glazing Manufacturer" font_size="4vw" font_size_phone="2em" font_line_height="1.2" font_size_tablet="7vw" text_direction="default"][/split_line_heading][divider line_type="No Line" custom_height="3vw"][vc_column_text css="" text_direction="default"]Getting the best performance from an IGU isn't simply about choosing between **double glazing or triple glazing**. Glass thickness, unit construction, U-value, g-value, solar gain, safety requirements, acoustic performance, frame limitations and the size and location of the glazing all affect the correct specification. Crystal Units works as a **technical glazing and manufacturing partner**, helping window manufacturers and installers get that specification right before the glass enters production. Our technical team can support you with: - Double and triple glazing specifications - C.U.in IGU specifications - Glass thickness calculations - Wind load calculations - Barrier load requirements - U-values and thermal performance - Solar control and g-values - Low-E coated glass - Laminated and acoustic glass - Large and unusual glazing applications - Relevant glazing standards and performance requirements The aim is simple: **design the glass correctly before manufacture, manufacture it correctly the first time and reduce problems when it reaches site.**[/vc_column_text][divider

This allows it to achieve thermal performance associated with high-performance triple glazing without requiring a conventional third pane of glass.[/vc_column_text][/toggle][toggle color="Accent-Color" heading_tag="default" heading_tag_functionality="default" title="Can C.U.in fit into a double glazed frame?"][vc_column_text css="" text_direction="default"]Certain C.U.in configurations are slim enough to be installed into many window systems originally designed for double glazed units. This can make C.U.in particularly useful for replacement and retrofit projects where conventional triple glazing may be too thick or heavy. The existing frame, glazing rebate and required IGU specification should always be checked before manufacture.[/vc_column_text][/toggle][toggle color="Accent-Color" heading_tag="default" heading_tag_functionality="default" title="Is C.U.in better than triple glazing?"][vc_column_text css="" text_direction="default"]It depends on the project and specification. C.U.in can achieve U-values as low as **0.4 W/m²K** while using two panes of glass and suspended film rather than three panes. This can provide significant advantages where unit thickness, glass weight and frame compatibility make conventional triple glazing difficult. Crystal Units can compare the requirements and recommend the correct glazing specification for the application.[/vc_column_text][/toggle][toggle color="Accent-Color" heading_tag="default" heading_tag_functionality="default" title="What is the U-value of C.U.in compared with double and triple glazing?"][vc_column_text css="" text_direction="default"]C.U.in can achieve U-values as low as **0.4 W/m²K**, depending on the configuration. An independent C.U.in study compared a 36mm C.U.in unit at 0.4 W/m²K with a typical 28mm double glazed unit at 1.0 W/m²K, a 36mm triple glazed unit at 0.9 W/m²K and a typical 50mm triple glazed unit at 0.6 W/m²K.[/vc_column_text][/toggle][toggle color="Accent-Color" heading_tag="default" heading_tag_functionality="default" title="Does C.U.in use three panes of glass?"][vc_column_text css="" text_direction="default"]No. C.U.in uses two panes of glass with a virtually invisible suspended film between them. The film creates a second insulating cavity without adding a third pane of glass.[/vc_column_text][/toggle][toggle color="Accent-Color" heading_tag="default" heading_tag_functionality="default" title="Can C.U.in replace double glazing without replacing the windows?"][vc_column_text css="" text_direction="default"]Potentially, yes. Depending on the existing window frame, glazing rebate and required IGU thickness, C.U.in can provide a route to significantly improved thermal performance while retaining the existing frame. Crystal Units can review the required specification before manufacture.[/vc_column_text][/toggle][toggle color="Accent-Color" heading_tag="default" heading_tag_functionality="default" title="Can Crystal Units manufacture double and triple glazed units?"][vc_column_text css="" text_direction="default"]Yes. Crystal Units manufactures high-performance insulating glass units for window manufacturers, glaziers and installers, including conventional double glazing, triple glazing and advanced C.U.in suspended film units. Our technical team can help identify which construction is most appropriate for the required U-value, frame system and application.[/vc_column_text][/toggle][toggle color="Accent-Color" heading_tag="default" heading_tag_functionality="default" title="Can I replace my current triple glazing units in my current windows?"][vc_column_text text_direction="default"]Yes C.U.in can be replaced into virtually any window that already has double or triple glazing installed.[/vc_column_text][/toggle][toggle color="Accent-Color" heading_tag="default" heading_tag_functionality="default" title="Does C.U.in come in a maximum size?"][vc_column_text text_direction="default"]The maximum size for C.U.in is 3000mm x 6000mm[/vc_column_text][/toggle][/toggles][/vc_column][/vc_row]
