Standard market doors often use 1.2mm &#8211; 1.4mm aluminum.<\/li>\n\n\n\n<li><strong>Hotian Advantage:<\/strong>\u00a0For our commercial entrance systems, we utilize\u00a0<strong>2.0mm &#8211; 3.0mm thick thermal break aluminum profiles<\/strong>. This prevents frame distortion under heavy wind loads or when supporting oversized glass units (up to 3 meters high).<\/li>\n\n\n\n<li>\ud83d\udc49\u00a0<strong>Designing a heavy-duty entrance?

Thermal Break (The Energy Shield)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What it is:<\/strong>\u00a0You will see a black strip crimped between the interior and exterior aluminum profiles. This is the\u00a0<strong>Polyamide (PA66) Thermal Break<\/strong>.<\/li>\n\n\n\n<li><strong>Why it matters:<\/strong>\u00a0Aluminum is a conductor. Without this break, the frame acts as a &#8220;thermal bridge,&#8221; transferring outdoor cold\/heat inside.<\/li>\n\n\n\n<li><strong>Engineering Detail:<\/strong>\u00a0We use\u00a0<strong>PA66 GF25<\/strong>\u00a0(25% glass fiber reinforced nylon) strips. In our Passive House series, these strips are up to\u00a0<strong>34mm wide<\/strong>, significantly lowering the U-value to meet strict energy codes (Energy Star \/ NFRC).<br>\ud83d\udc49\u00a0<strong>Need U-value reports for your project?

Threshold &amp; Sill (Water Management)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The bottom component of the frame is critical for weatherproofing.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High-Step Threshold:<\/strong>\u00a0Offers the best water tightness (high Pascal rating) for exterior doors exposed to direct rain.<\/li>\n\n\n\n<li><strong>Flush Sill (Zero Threshold):<\/strong>\u00a0Essential for modern aesthetics and\u00a0<strong>ADA compliance<\/strong>\u00a0(wheelchair access).<\/li>\n\n\n\n<li><strong>The Challenge:<\/strong>\u00a0Flush sills notoriously leak water.<\/li>\n\n\n\n<li><strong>The Solution:<\/strong>\u00a0Hotian employs a\u00a0<strong>&#8220;Hidden Drain&#8221; subsystem<\/strong>. We engineer a sub-sill drainage channel that sits below the floor level, allowing for a seamless, flush look while capturing and diverting water away from the building foundation.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">D. Architrave &amp; Brickmold (The Integration)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">These are the exterior trim components that seal the gap between the window frame and the building facade (cladding, brick, or siding).<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Nailing Fin:<\/strong>\u00a0For US markets, we provide integral\u00a0<strong>Nailing Fins<\/strong>\u00a0for easy installation in wood-frame construction.<\/li>\n\n\n\n<li><strong>Brickmold:<\/strong>\u00a0For renovation projects or masonry openings, our snap-on brickmolds provide a clean finish without messy wet sealing.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Door Panel Components<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The &#8220;Sash&#8221; (or leaf) is the operational element of the door.

Over time, gravity causes the sash to sag (drag on the floor).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">B. The Glazing System (Glass Specs)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Glass typically occupies 80% of a door&#8217;s surface area, making it the biggest factor in thermal performance.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>IGU (Insulated Glass Unit):<\/strong>\u00a0We standardly offer\u00a0<strong>Double Glazing (5mm+12A+5mm)<\/strong>\u00a0but recommend\u00a0<strong>Triple Glazing<\/strong>\u00a0for cold climates.<\/li>\n\n\n\n<li><strong>Warm Edge Spacers (TGI):<\/strong>\u00a0Instead of conductive aluminum spacers, we use composite &#8220;Warm Edge&#8221; spacers between glass panes to prevent condensation at the glass edges.<\/li>\n\n\n\n<li><strong>Low-E Coatings:<\/strong>\u00a0Soft-coat Low-E (Low-Emissivity) layers are applied to reflect infrared heat\u2014keeping heat inside during winter and outside during summer.\n<ul class=\"wp-block-list\">\n<li><em>Option:<\/em>\u00a0<strong>Switchable Privacy Glass (Smart Glass)<\/strong>\u00a0is available for luxury hotel or office projects.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">C. Glazing Bead (Security &amp; Aesthetics)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Definition:<\/strong>\u00a0The aluminum strip that snaps into the sash to hold the glass unit in place.<\/li>\n\n\n\n<li><strong>Security Feature:<\/strong>\u00a0For commercial projects, we spec\u00a0<strong>Internal Glazing Beads<\/strong>.

Unique parts include:\n<ul class=\"wp-block-list\">\n<li><strong>Astragal:<\/strong> A vertical molding strip attached to the edge of one door in a pair. It covers the gap between the two doors when closed, providing a seal and sometimes housing locking mechanisms.<\/li>\n\n\n\n<li><strong>Multipoint Locks:<\/strong> Locking systems that secure the door at multiple points (top, bottom, middle) with a single handle operation, common on taller French doors or patio doors for security and sealing.<\/li>\n\n\n\n<li><strong>Flush Bolts:<\/strong> As mentioned before, used to secure the inactive door.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>B.

Metric sizes are used in many other parts of the world.<\/li>\n\n\n\n<li><strong>B. Hardware Positioning:<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Backset:<\/strong> The distance from the edge of the door to the center of the hole bored for the lockset (common backsets are 2 \u215c&#8221; and 2 \u00be&#8221;). Critical for ensuring the lock fits correctly.<\/li>\n\n\n\n<li><strong>Bore Size:<\/strong> The diameter of the main hole(s) drilled for the lockset\/deadbolt. Needs to match the hardware requirements.<\/li>\n\n\n\n<li><strong>Hinge Spacing &amp; Gap:<\/strong> Hinges need to be placed correctly along the jamb and door edge. Small, consistent gaps around the door panel are needed for it to swing freely without binding.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>C. Installation Tolerances:<\/strong> There are acceptable ranges for gaps and clearances around the door and frame to allow for smooth operation and seasonal wood movement. Building codes might specify certain clearances, especially for fire doors.<\/li>\n\n\n\n<li><strong>D. Ratings &amp; Standards:<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>ANSI\/BHMA:<\/strong> Look for grades (like Grade 1, 2, 3) on hardware indicating performance, durability, and security standards set by the American National Standards Institute \/ Builders Hardware Manufacturers Association. Grade 1 is typically the highest\/most durable.<\/li>\n\n\n\n<li><strong>Fire Ratings:<\/strong> Doors (and frames\/hardware) used in specific locations (like between garage and house) need fire ratings (e.g., 20-minute, 90-minute) indicating how long they resist fire.<\/li>\n\n\n\n<li><strong>Sound Ratings (STC):<\/strong> Sound Transmission Class ratings indicate how well a door assembly blocks sound. Higher STC means better soundproofing.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Accessibility &amp; Specialized Components: Meeting Specific Needs<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Some components are designed for specific requirements:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A.
