Sometimes the frame is too large, requiring additional wall chiseling. Other times, it is too small and needs to be filled with an unusually thick layer of silicone, which can make the installation less durable and more prone to leakage.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 110%;\">What many people misunderstand is thinking that \u201caluminum frames\u201d come in only one size. In fact, there are several standard sizes available, and choosing the right size from the beginning can save a lot of time and repair costs.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 110%;\">This article explains the dimensions of aluminum frames (width \u00d7 depth), their relationship with wall opening sizes, and guidelines for choosing the right frame size based on the type of door or window panel.

It supports the weight of the entire system. The frame size is measured by the face width and depth of the profile.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 110%;\">Sash: The movable part of the system, such as sliding panels, casement panels, or folding panels. The sash moves either inside or outside the frame.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 110%;\">Glass: Installed inside the sash. The glass thickness must correspond with the glass groove depth of the profile.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400; font-size: 110%;\">The size discussed in this article refers only to the dimensions of the \u201cframe\u201d: the face width and the depth that fits into the wall. It does not refer to the thickness of the aluminum material itself.<\/span><\/p>\n<h3><span style=\"font-size: 110%;\"><b>Why Is Frame Size More Important Than Many People Realize?<\/b><\/span><\/h3>\n<p><span style=\"font-weight: 400; font-size: 110%;\">An aluminum frame that does not fit the wall opening properly can cause problems in 3 main areas:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 110%;\">Appearance: If the gap between the frame and the wall is wider than 15 mm, an unusually thick layer of silicone will be needed. This can make the finished work look rough and untidy.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 110%;\">Firmness and waterproofing: A wide gap reduces the silicone\u2019s ability to withstand water pressure, increasing the risk of leaks during the rainy season.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 110%;\">Structural stability: A frame that is too narrow for a heavy or large panel may not be able to support the weight properly. Over time, this can cause the panel to sag or prevent the lock from closing properly.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400; font-size: 110%;\">Based on SGQ\u2019s repair project data: More than 60% of frame leakage repairs are caused by choosing a frame size that is not suitable for the wall opening, rather than by material defects.<\/span><\/p>\n\n\n<span id=\"standard-sizes\"><\/span>\n\n\t<div id=\"gap-1421449910\" class=\"gap-element clearfix\" style=\"display:block; height:auto;\">\n\t\t\n<style>\n#gap-1421449910 {\n  padding-top: 40px;\n}\n<\/style>\n\t<\/div>\n\t\n\n<h2><span style=\"font-size: 120%;\"><b>How Many Standard Aluminum Frame Sizes Are There?

It also affects their load-bearing capacity and the glass size they can support:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 110%;\">3-Inch Aluminum Frame (75 mm): Face width of 75 mm with a depth of approximately 38\u201345 mm. It can support glass up to 8 mm thick and is suitable for general residential projects with panels not larger than 1.5 meters.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 110%;\">4-Inch Aluminum Frame (100 mm): Face width of 100 mm with a depth of approximately 45\u201355 mm. It can support glass up to 12 mm thick and has a larger section area, allowing it to handle greater bending moments. It is suitable for panels 1.5\u20133 meters wide.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400; font-size: 110%;\">Based on SGQ technicians\u2019 experience across more than 500 projects: 3-inch frames can support around 90% of general applications. However, if the panel is wider than 1.5 meters or uses heavier insulated glass, a 4-inch frame or larger should always be used.

In Thailand\u2019s climate, where temperatures can vary by 30\u201335\u00b0C per day, a 1-meter frame can expand by up to 0.7\u20130.8 mm. The clearance helps accommodate this expansion.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 110%;\">Construction Tolerance: Brick walls or concrete walls usually have a standard tolerance of around \u00b15 mm.

In this case, there are 2 possible approaches:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 110%;\">If the wall opening is off-standard by less than 15 mm: Choose the closest frame size, then use packers or shims to level the gap before applying silicone. This method can be done without chiseling the wall.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 110%;\">If the wall opening is off-standard by more than 15 mm: The wall must be chiseled or filled to the required size first. It is not recommended to force an oversized frame into a smaller opening, as this can affect the locking performance and overall tightness of the system.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400; font-size: 110%;\">How to Measure a Wall Opening Correctly Before Ordering a Frame: Measure the opening width at 3 points: top, middle, and bottom. Then measure the opening height at 3 points: left, middle, and right. Use the smallest value of each dimension for calculation, because any swollen or warped section of the wall will obstruct the installation at the narrowest point.<\/span><\/p>\n\n\n<span id=\"by-door-type\"><\/span>\n\n\t<div id=\"gap-193383094\" class=\"gap-element clearfix\" style=\"display:block;

Aluminum frames also include grooves for rubber seals, locking hardware, and tracks, so the dimensions that fit into the wall are different.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400; font-size: 110%;\">Conclusion for Renovation Projects: Do not measure the existing wooden frame and order an aluminum frame in the exact same size.

Is There a Big Price Difference Between 3-Inch and 4-Inch Frames?<\/h3>\n    <p style=\"font-size:17px;margin:0;line-height:1.8;\">In general, 4-inch frames are approximately 15\u201325% more expensive than 3-inch frames because they use more aluminum material and have a larger section area. The price difference per length is not very high, but for medium to large-scale projects, it can affect the overall material cost. However, choosing a 3-inch frame for work that actually requires a 4-inch frame just to save on material costs often leads to higher repair costs later.<\/p>\n  <\/div>\n\n  <div style=\"padding:24px 0;border-bottom:1px solid #e5e7eb;\">\n    <h3 style=\"font-size:17px;color:#23345c;font-weight:700;margin-bottom:10px;line-height:1.6;\">2. How Should You Measure the Wall Opening for an Aluminum Frame?<\/h3>\n    <p style=\"font-size:17px;margin:0;line-height:1.8;\">Measure the opening width at 3 points: top, middle, and bottom. Then measure the opening height at 3 points: left, middle, and right. Use the smallest value of each dimension because any swollen or warped part of the wall will create an obstacle at the narrowest point. Then subtract 20\u201330 mm for the total clearance on both sides. The final number is the outside dimension (OD) of the frame that can be ordered. Not sure?

Can Standard Aluminum Frames and Euro Profile Frames Be the Same Size or Used Interchangeably?<\/h3>\n    <p style=\"font-size:17px;margin:0;line-height:1.8;\">No. Even though the face width of some models may be similar, the depth is different. The positions of the glass grooves, seal grooves, and system holes are also not the same. Using a Euro Profile frame with a standard system, or using a standard frame with a Euro Profile system, can cause the panels to close improperly, seals to leak, and hardware components to not fit correctly. The full profile system, including the frame, sash, and hardware, should always be selected from the same brand and series.<\/p>\n  <\/div>\n\n  <div style=\"padding:24px 0;border-bottom:1px solid #e5e7eb;\">\n    <h3 style=\"font-size:17px;color:#23345c;font-weight:700;margin-bottom:10px;line-height:1.6;\">4. Can a Warped Aluminum Frame Be Repaired, or Does It Need to Be Replaced?<\/h3>\n    <p style=\"font-size:17px;margin:0;line-height:1.8;\">It depends on the level of warping. If the frame is warped by less than 5 mm, it can be adjusted by refastening the frame screws and adding shims to level it properly. If the frame is warped by more than 10 mm or the profile is cracked, replacing the frame is recommended. Forcing a heavily warped frame back into position can still cause the panel to close improperly and the seal to leak. The SGQ technician team can provide a free assessment to check whether your case can be repaired or needs replacement.<\/p>\n  <\/div>\n\n  <div style=\"padding:24px 0;border-bottom:1px solid #e5e7eb;\">\n    <h3 style=\"font-size:17px;color:#23345c;font-weight:700;margin-bottom:10px;line-height:1.6;\">5.
