Particular care must be taken with fasteners and joint sealing.<\/li>\n\n\n\n<li><strong>Glazing quality:<\/strong> To limit heat loss, double or triple glazing is used, sometimes filled with inert gas. For example, two low-emissivity panes of glass filled with argon transmit five times less heat than a single pane of glass.<\/li>\n\n\n\n<li><strong>Treatment of thermal bridges:<\/strong> breakers and insulating joints are necessary to prevent heat loss. The comparative table of materials shows that glass has a higher U-value (transmits more heat) than opaque materials such as wood or brick.<\/li>\n\n\n\n<li><strong>Reduction of glare and solar gain:<\/strong> the use of low-emissivity or tinted glazing reduces solar gain and glare, but decreases light transmission. Less natural light means an increased need for artificial lighting.<\/li>\n\n\n\n<li><strong>Maintenance:<\/strong> with regular maintenance (checking seals and washing every 3\u20136 months), a glass facade can last up to 70 years.<\/li>\n\n\n\n<li><strong>Regulations and safety:<\/strong> the use of safety glass (tempered, laminated) is essential to prevent dangerous breakage. In seismic areas, glass must be designed to withstand movement and limit breakage.<\/li>\n<\/ul>\n\n\n\n<div class=\"wp-block-media-text is-stacked-on-mobile\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"666\" src=\"https:\/\/stekar.com\/wp-content\/uploads\/2025\/08\/06-MaryRobert_Drone_StephaneGroleau-430-500x325-1-1024x666.jpg\" alt=\"\" class=\"wp-image-1393 size-full\" srcset=\"https:\/\/stekar.com\/wp-content\/uploads\/2025\/08\/06-MaryRobert_Drone_StephaneGroleau-430-500x325-1-1024x666.jpg 1024w, https:\/\/stekar.com\/wp-content\/uploads\/2025\/08\/06-MaryRobert_Drone_StephaneGroleau-430-500x325-1-500x325.jpg 500w, https:\/\/stekar.com\/wp-content\/uploads\/2025\/08\/06-MaryRobert_Drone_StephaneGroleau-430-500x325-1-768x499.jpg 768w, https:\/\/stekar.com\/wp-content\/uploads\/2025\/08\/06-MaryRobert_Drone_StephaneGroleau-430-500x325-1.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<p>This building, a large-scale condominium tower in Montreal, incorporates the Multifa\u00e7ades with glass cladding modules.<\/p>\n<\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Why Use Glass Cladding Instead of Curtain Walls?<\/h2>\n\n\n\n<p>Curtain walls, whether prefabricated or traditional (stick-built), offer spectacular aesthetics but have well-known limitations.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1.

Here are its main advantages:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Seamless integration of glazing and opaque areas:<\/strong> thanks to a patented window (SM160) aligned with the cladding, the system creates a fluid appearance similar to a curtain wall while reducing the proportion of glazed surface area when energy efficiency requires it.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/stekar.com\/en\/pressure-balanced-facade-system-functions-principles\/\">Pressure equalization principle<\/a><\/strong>: the Multifa\u00e7ades is based on a ventilated cavity that equalizes pressure on both sides of the cladding, preventing water from penetrating and ensuring excellent wind resistance. <\/li>\n\n\n\n<li><strong>Thermal and acoustic performance:<\/strong> the system exceeds North American standards for insulation, air and water tightness, and wind resistance. The alignment of the glazing with the insulation limits thermal bridges and improves energy efficiency.<\/li>\n\n\n\n<li><strong>Design flexibility:<\/strong> architects can choose the shape (rectangular, trapezoidal, curved) and size of the panels, up to 5 m\u00b2 for an opaque module. The system is suitable for a wide variety of buildings\u2014schools, hotels, residential or office towers\u2014and is particularly effective when the facade has more than 60% opaque surface area.<\/li>\n\n\n\n<li><a href=\"https:\/\/stekar.com\/en\/building-facade-renovation-challenges-approach-results\/\"><strong>Suitable for renovations:<\/strong> <\/a>the independence of the panels and prefabrication facilitate installation in renovation projects.

Pressure-balanced systems such as Multifa\u00e7ades, developed by STEKAR, combine glazing and opaque cladding to optimize comfort and energy efficiency while maintaining a contemporary aesthetic. This type of system offers great design flexibility, better solar gain management, and simplified maintenance. It is a solid alternative to traditional curtain walls and meets increased performance and sustainability requirements.<\/p>\n\n\n\n<p>For each project, it is recommended to:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Assess the climate and orientation:<\/strong> in areas with high levels of sunlight or strong winds, limit the amount of glazing and opt for solar control glazing and opaque cladding.<\/li>\n\n\n\n<li><strong>Consider local regulations:<\/strong> some standards impose minimum insulation values or prohibit certain cladding materials.<\/li>\n\n\n\n<li><strong>Working with experts:<\/strong> The design and installation of a glass or hybrid fa\u00e7ade requires the expertise of building envelope specialists to ensure watertightness, durability, and compliance with standards.<\/li>\n\n\n\n<li><strong>Compare solutions:<\/strong> Modular systems such as the Multifa\u00e7ades allow you to take advantage of glass while controlling thermal performance and carbon footprint. Comparing these solutions to conventional curtain walls helps you choose the option best suited to your project objectives.<\/li>\n<\/ol>\n\n\n\n<p>By incorporating these considerations, architects can design facades that combine elegance and efficiency, striking the right balance between transparency and performance.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Glass cladding refers to non-load-bearing glass cladding used in modern facades.
