id=\"introduction\" class=\"text-xl font-bold mt-1 -mb-0.5\">Introduction<\/h2>\n<p class=\"whitespace-pre-wrap break-words\">In the world of modern architecture and interior design, sliding systems with large glazing are becoming increasingly popular. One of the most advanced solutions available on the Polish market is the MB-77 HS Narrow Mullion &#8211; aluminum lift-and-slide doors from the renowned manufacturer Aluprof.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">What distinguishes this system is the narrow mullion variant with a width of just 47.5 mm at the junction of the sashes. This feature, seemingly minor, drastically changes the character of the entire structure in practice, providing more light and a more minimalist appearance.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">Sapor.pl offers this system in the HI (High Insulation) version with additional thermal insulation, emphasizing their specialization in premium products. But does the MB-77 HS Narrow Mullion system actually meet the expectations of demanding clients &#8211; architects, distributors, and end users? In this review, we&#8217;ll examine it step by step.<\/p>\n<p class=\"whitespace-pre-wrap break-words\"><img decoding=\"async\" class=\"lazyload alignnone size-full wp-image-12272\" src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10.jpg\" data-orig-src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10.jpg\" alt=\"Aluprof MB-77 Narrow Mullion Window Review\" width=\"2048\" height=\"1150\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%272048%27%20height%3D%271150%27%20viewBox%3D%270%200%202048%201150%27%3E%3Crect%20width%3D%272048%27%20height%3D%271150%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-srcset=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10-200x112.jpg 200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10-300x168.jpg 300w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10-400x225.jpg 400w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10-600x337.jpg 600w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10-768x431.jpg 768w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10-800x449.jpg 800w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10-1024x575.jpg 1024w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10-1200x674.jpg 1200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10-1536x863.jpg 1536w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-10.jpg 2048w\" data-sizes=\"auto\" data-orig-sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/p>\n<h2 id=\"specifications-and-first-impressions\" class=\"text-xl font-bold mt-1 -mb-0.5\">Specifications and First Impressions<\/h2>\n<p class=\"whitespace-pre-wrap break-words\">The MB-77 HS Narrow Mullion system impresses at the technical specification level. The construction offers a frame depth of 174 mm in the 2-track variant or 271 mm in the 3-track version, with a sash depth of 77 mm. What sets this system apart is the possibility of creating truly large glazing &#8211; the maximum sash height reaches 3.24 m, width up to 3.3 m, and weight can reach up to 600 kg!<\/p>\n<p class=\"whitespace-pre-wrap break-words\">The system is adapted for single or double-chamber glass packages with a thickness of 13.5-58.5 mm, which provides great flexibility in selecting the appropriate glazing depending on project needs.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">The first impression upon seeing the MB-77 HS Narrow Mullion construction is striking &#8211; the mullion with a width of just 47.5 mm (or 50 mm in some variants) makes the glazing appear almost uninterrupted. Compared to standard systems, where mullions can be 70-100 mm, the difference is immediately noticeable.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">The HI version offered by Sapor.pl features additional insulating elements &#8211; a central chamber with insulation insert or thermal barrier, which translates into impressive thermal parameters. The heat transfer coefficient Uw can reach a value as low as 0.72 W\/(m\u00b2K) in the best configurations (e.g., with a triple-glazed package Ug=0.6 W\/(m\u00b2K)).<\/p>\n<p class=\"whitespace-pre-wrap break-words\">The system is available in a wide range of RAL colors (over 200 shades), including matte, metallic, and structural finishes, which gives enormous possibilities for adaptation to architectural concepts.<\/p>\n<p class=\"whitespace-pre-wrap break-words\"><img decoding=\"async\" class=\"lazyload alignnone size-full wp-image-12266\" src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9.jpg\" data-orig-src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9.jpg\" alt=\"Aluprof MB-77 Narrow Mullion Window Review\" width=\"2048\" height=\"1150\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%272048%27%20height%3D%271150%27%20viewBox%3D%270%200%202048%201150%27%3E%3Crect%20width%3D%272048%27%20height%3D%271150%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-srcset=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9-200x112.jpg 200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9-300x168.jpg 300w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9-400x225.jpg 400w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9-600x337.jpg 600w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9-768x431.jpg 768w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9-800x449.jpg 800w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9-1024x575.jpg 1024w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9-1200x674.jpg 1200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9-1536x863.jpg 1536w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-9.jpg 2048w\" data-sizes=\"auto\" data-orig-sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/p>\n<h2 id=\"practical-advantages\" class=\"text-xl font-bold mt-1 -mb-0.5\">Practical Advantages<\/h2>\n<h3 class=\"text-lg font-bold mt-1 -mb-1.5\">Aesthetics and Design<\/h3>\n<p class=\"whitespace-pre-wrap break-words\">The greatest advantage of the MB-77 HS Narrow Mullion system is its minimalist appearance, which perfectly fits into modern architectural trends. The narrow mullion makes the boundary between interior and exterior even less visible, and rooms gain more natural light.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">This is particularly important for architects designing premium buildings, where every detail matters. The system perfectly complements both minimalist and Scandinavian interior design styles.<\/p>\n<p><img decoding=\"async\" class=\"lazyload alignnone size-full wp-image-12236\" src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4.jpg\" data-orig-src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4.jpg\" alt=\"Aluprof MB-77 Narrow Mullion Window Review\" width=\"2048\" height=\"1150\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%272048%27%20height%3D%271150%27%20viewBox%3D%270%200%202048%201150%27%3E%3Crect%20width%3D%272048%27%20height%3D%271150%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-srcset=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4-200x112.jpg 200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4-300x168.jpg 300w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4-400x225.jpg 400w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4-600x337.jpg 600w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4-768x431.jpg 768w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4-800x449.jpg 800w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4-1024x575.jpg 1024w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4-1200x674.jpg 1200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4-1536x863.jpg 1536w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-4.jpg 2048w\" data-sizes=\"auto\" data-orig-sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/p>\n<h3 class=\"text-lg font-bold mt-1 -mb-1.5\">Functionality<\/h3>\n<p class=\"whitespace-pre-wrap break-words\">The lift-and-slide mechanism is a huge advantage in everyday use. Unlike traditional patio doors, the HST system doesn&#8217;t take up space in the room when opening, which is extremely important for smaller spaces.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">Additional options, such as the automatic &#8220;HS e-Power&#8221; drive with obstacle detection or the &#8220;Comfort Close&#8221; and &#8220;HS Speed Limiter&#8221; mechanisms, increase user comfort, especially with large and heavy sashes.<\/p>\n<h3 class=\"text-lg font-bold mt-1 -mb-1.5\">Thermal and Acoustic Insulation<\/h3>\n<p class=\"whitespace-pre-wrap break-words\">The MB-77 HS Narrow Mullion system in the HI version offers excellent insulation parameters. The Uw coefficient of 0.72 W\/(m\u00b2K) places this system among the best solutions available on the market.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">This translates into real energy savings and thermal comfort. Even on cold days, the space near the windows doesn&#8217;t become colder, which eliminates the &#8220;draft&#8221; effect often felt with older window systems.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">Equally impressive is the acoustic insulation, thanks to the use of thermal breaks, high-quality gaskets, and modern hardware, such as G-U with 3 locking bolts. This is particularly important for buildings located in noisy urban locations.<\/p>\n<p><img decoding=\"async\" class=\"lazyload alignnone size-full wp-image-12230\" src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3.jpg\" data-orig-src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3.jpg\" alt=\"Aluprof MB-77 Narrow Mullion Window Review\" width=\"2048\" height=\"1150\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%272048%27%20height%3D%271150%27%20viewBox%3D%270%200%202048%201150%27%3E%3Crect%20width%3D%272048%27%20height%3D%271150%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-srcset=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3-200x112.jpg 200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3-300x168.jpg 300w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3-400x225.jpg 400w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3-600x337.jpg 600w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3-768x431.jpg 768w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3-800x449.jpg 800w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3-1024x575.jpg 1024w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3-1200x674.jpg 1200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3-1536x863.jpg 1536w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-3.jpg 2048w\" data-sizes=\"auto\" data-orig-sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/p>\n<h3 class=\"text-lg font-bold mt-1 -mb-1.5\">Durability and Security<\/h3>\n<p class=\"whitespace-pre-wrap break-words\">Aluminum profiles with cladding and impregnation are exceptionally resistant to moisture, corrosion, and harsh weather conditions. Unlike PVC or wooden systems, the MB-77 HS Narrow Mullion practically requires no maintenance and maintains its properties for many years.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">The system also offers a high level of security thanks to anti-burglary details and solid hardware, which is particularly important for large glazing that potentially constitutes a weak point in building security.<\/p>\n<p class=\"whitespace-pre-wrap break-words\"><img decoding=\"async\" class=\"lazyload alignnone size-full wp-image-12260\" src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8.jpg\" data-orig-src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8.jpg\" alt=\"Aluprof MB-77 Narrow Mullion Window Review\" width=\"2048\" height=\"1150\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%272048%27%20height%3D%271150%27%20viewBox%3D%270%200%202048%201150%27%3E%3Crect%20width%3D%272048%27%20height%3D%271150%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-srcset=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8-200x112.jpg 200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8-300x168.jpg 300w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8-400x225.jpg 400w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8-600x337.jpg 600w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8-768x431.jpg 768w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8-800x449.jpg 800w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8-1024x575.jpg 1024w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8-1200x674.jpg 1200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8-1536x863.jpg 1536w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-8.jpg 2048w\" data-sizes=\"auto\" data-orig-sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/p>\n<h2 id=\"disadvantages-and-challenges\" class=\"text-xl font-bold mt-1 -mb-0.5\">Disadvantages and Challenges<\/h2>\n<h3 class=\"text-lg font-bold mt-1 -mb-1.5\">Price<\/h3>\n<p class=\"whitespace-pre-wrap break-words\">The biggest barrier when choosing the MB-77 HS Narrow Mullion system is its price. As a premium product, it is significantly more expensive than standard PVC windows or even simpler aluminum constructions, such as Aluprof MB-70.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">The cost depends on the configuration but is always higher than the market average. It is a solution definitely aimed at the premium segment, which limits its availability to a wider audience.<\/p>\n<h3 class=\"text-lg font-bold mt-1 -mb-1.5\">Weight and Installation Requirements<\/h3>\n<p class=\"whitespace-pre-wrap break-words\">Large sashes, which can weigh up to 600 kg, place high demands on installation and building structure. Unprofessional installation can lead to problems with system functioning, and in extreme cases, even damage to the building structure.<\/p>\n<p class=\"whitespace-pre-wrap break-words\">This requires collaboration with experienced installation teams, which can further increase investment costs. This is particularly important when modernizing existing buildings, where the structure may not be adapted to such heavy loads.<\/p>\n<h3 class=\"text-lg font-bold mt-1 -mb-1.5\">Availability of Additional Options<\/h3>\n<p class=\"whitespace-pre-wrap break-words\">Many advanced features, such as automatic drives or corner constructions without a mullion, are available as additional options, which involves extra costs. They are not standardly included in the basic offer, which can lead to misunderstandings at the quotation stage.<\/p>\n<p class=\"whitespace-pre-wrap break-words\"><img decoding=\"async\" class=\"lazyload alignnone size-full wp-image-12254\" src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7.jpg\" data-orig-src=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7.jpg\" alt=\"Aluprof MB-77 Narrow Mullion Window Review\" width=\"2048\" height=\"1150\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%272048%27%20height%3D%271150%27%20viewBox%3D%270%200%202048%201150%27%3E%3Crect%20width%3D%272048%27%20height%3D%271150%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-srcset=\"https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7-200x112.jpg 200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7-300x168.jpg 300w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7-400x225.jpg 400w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7-600x337.jpg 600w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7-768x431.jpg 768w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7-800x449.jpg 800w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7-1024x575.jpg 1024w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7-1200x674.jpg 1200w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7-1536x863.jpg 1536w, https:\/\/sapor.pl\/wp-content\/uploads\/2025\/03\/Recenzja-okna-Aluprof-MB-77-waski-slupek-7.jpg 2048w\" data-sizes=\"auto\" data-orig-sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/p>\n<h2 id=\"comparison-with-competitors\" class=\"text-xl font-bold mt-1 -mb-0.5\">Comparison with Competitors<\/h2>\n<p class=\"whitespace-pre-wrap break-words\">Comparing the MB-77 HS Narrow Mullion with alternatives available on the market, one can notice both its strengths and weaknesses:<\/p>\n<h3 class=\"text-lg font-bold mt-1 -mb-1.5\">Sch\u00fcco ASS 77 PD.HI<\/h3>\n<ul class=\"list-disc space-y-1.5 pl-7\">\n<li class=\"whitespace-normal break-words\">Better insulation (Uw=0.70), but higher price<\/li>\n<li class=\"whitespace-normal break-words\">Less flexibility in offering narrow mullion options<\/li>\n<li class=\"whitespace-normal break-words\">Often longer delivery times<\/li>\n<\/ul>\n<h3 class=\"text-lg font-bold mt-1 -mb-1.5\">Aliplast Ultraglide<\/h3>\n<ul class=\"list-disc space-y-1.5 pl-7\">\n<li class=\"whitespace-normal break-words\">Slightly narrower mullion (45 mm)<\/li>\n<li class=\"whitespace-normal break-words\">Lower price (about 2506 EUR vs. 2630 EUR for MB-77 HS according to Debesto ranking)<\/li>\n<li class=\"whitespace-normal break-words\">Worse heat transfer coefficient (Uw=0.86)<\/li>\n<\/ul>\n<h3 class=\"text-lg font-bold mt-1 -mb-1.5\">Ponzio SL1600TT<\/h3>\n<ul class=\"list-disc space-y-1.5 pl-7\">\n<li class=\"whitespace-normal break-words\">More minimalist design (126 mm assembly)<\/li>\n<li class=\"whitespace-normal break-words\">Higher price (3111 EUR)<\/li>\n<li class=\"whitespace-normal break-words\">Lower insulation (Uw=0.99)<\/li>\n<\/ul>\n<p class=\"whitespace-pre-wrap break-words\">In industry rankings, such as Debesto 2023, MB-77 HS took 3rd place among aluminum HST systems for parameters (Uw=0.96 in the tested version) and narrow mullion (47.5 mm).<\/p>\n<p class=\"whitespace-pre-wrap break-words\">The choice between these systems depends mainly on priorities &#8211; if thermal insulation is most important, Sch\u00fcco may be a better solution.
