How to Choose Specs for Insulating Glass Doors and Windows? What Are the Hard Requirements for Curtain Wall Glass? In our years of making door and window glass, the two questions customers ask most are: "What specs are available for insulating glass doors and windows?" and "Can any glass be used for curtain walls?" As a glass factory, we'd say: the selection logic for these two is completely different—one depends on household needs, the other on the baseline set by codes.   Insulating Glass Doors and Windows: Specs Follow "Thickness + Gas Layer + Thickness" Insulating glass is commonly written as "5+9A+5," "5+12A+5," or "6+12A+6," representing the thickness of the two glass panes and the air layer between them. For residential doors and windows, 5+12A+5 and 6+12A+6 are the mainstream choices, balancing thermal insulation and cost-effectiveness. The air layer isn't better the thicker it is—beyond a certain thickness, the gas inside creates convection, and insulation performance actually drops. Glass factory reminder: for mid- and high-rise doors and windows, tempered insulating glass is recommended; when a single pane exceeds 2㎡, 5mm is no longer enough and you need to upgrade to 6mm or thicker. If low-frequency noise from the street is severe, simply thickening the insulating glass has limited effect—laminated insulating glass is the right solution.   Curtain Wall Glass: Safety Is the Bottom Line, and Codes Are Strict Curtain walls are not on the same level as ordinary doors and windows. Codes explicitly require safety glass for curtain walls, with thickness no less than 6mm, and rib glass for full-glass curtain walls no less than 12mm. When insulating glass is used for curtain walls, the gas layer thickness should be no less than 12mm, individual glass thickness should not be less than 6mm, and the thickness difference between the two panes should not exceed 3mm. In addition, curtain wall door and window glass must have edge treatment, and tempered glass surfaces must be free of damage. When a glass factory schedules production of curtain wall insulating glass, dual sealing is standard, and hidden-frame curtain walls also require silicone structural sealant—completely different from the weather-resistant sealant used for ordinary doors and windows.   In one sentence: when choosing insulating glass for door and window glass, look at the usage scenario; when choosing door and window glass for curtain walls, look at the code red lines. The glass factory gets the parameters right so you can use them safely.  

What Types of Glass Are Used for Doors and Windows? What Are the Common Types of Glass? As an experienced glass factory, we often receive inquiries: what types of glass are available for doors and windows? This question sounds simple, yet it directly affects heat insulation, sound insulation, safety and service life. Poor selection will lead to high replacement costs and poor living experience. Today, based on our practical production experience in the factory, we sort out common glass categories to help you avoid pitfalls during selection.   1. Clear Float Glass It is the most basic type, also known as clear glass. It features good light transmittance and affordable price, but its strength is relatively low. It will form sharp fragments once broken, suitable for scenarios with low safety requirements. Meanwhile, it serves as the base material for deep processing, and many processes start with this substrate.   2. Tempered Glass Tempered through high-temperature heating and rapid cooling, it is several times stronger than ordinary glass. It breaks into small granular pieces that cause less injury, making it the mainstream option for doors, windows and shower rooms. It is also the most mass-produced product in our glass factory. Note that cutting and drilling must be finished before tempering.   3. Insulated Glass It consists of two glass panes with an air cavity in between, delivering excellent sound and heat insulation performance. Argon gas can be filled into the cavity to further reduce heat transfer. It is the top choice for energy-saving doors and windows, ideal for families troubled by noise or large seasonal temperature differences. It is worth prioritizing if budget permits.   4. Laminated Glass A PVB film is sandwiched between two panes. Even when shattered, fragments stick firmly to the film and will not fall off easily, offering high safety. It is widely applied in floor-to-ceiling windows, sunroom roofs and railings.   5. Low-E Glass Coated with a low-emissivity layer on the surface, it reflects infrared rays. It blocks heat in summer and retains indoor heat in winter. It works best when combined with insulated structure. It is standard for high-end doors and windows and meets current building energy-saving trends. Though the upfront cost is higher, it brings long-term benefits.   6. Fire-resistant & Decorative Glass Fire-resistant glass resists cracking under fire, used for fire-rated doors and windows and other special areas. Hot-melt and artistic glass focus on decoration, adding unique aesthetics to doors and windows.   Closing Remarks There is no absolute good or bad for door and window glass. The suitable type depends on application scenarios and budget. Feel free to consult our factory if you have doubts. We can provide proper solutions according to your usage, and accept custom samples.

How to Remove Silicone Sealant from Glass: A Practical Guide from a Glass Factory When a renovation is nearing completion, silicone sealant marks are often left on glass. As a glass factory that works with glass every day, we have seen far too many cases where improper cleaning caused scratches, cloudiness, or damaged coatings. In fact, removing silicone sealant from glass is not difficult. The key is to "check the sealant, check the glass, and check the method." 1. First, Identify the Type of Sealant Common silicone sealants fall into two categories: acidic silicone and neutral silicone. Acidic sealant becomes hard after curing and has strong adhesion. Neutral sealant is more elastic and offers better weather resistance. There is also water-based acrylic sealant, which can be wiped off with water before it dries. Our glass factory recommends: if the sealant has not fully cured, gently lift the edge with a utility blade, then peel it off. Do not push it with your fingers, or it will spread thinner and stick more firmly. 2. Physical Removal Methods For cured sealant, use a single-edge blade or a dedicated plastic scraper, keeping it at about a 30° angle to the glass surface, pushing from the edge toward the center. Make sure the blade is brand new, rust-free, and nick-free; otherwise, it will leave scratches. For tempered glass and coated glass, plastic scrapers or bamboo strips are even more recommended to avoid metal contact. Before leaving the factory, our glass factory often uses a heat gun or hair dryer to soften residual sealant before scraping, which is more efficient. 3. Chemical Removal Methods Silicone sealant can be removed with alcohol, acetone, banana oil, or a dedicated sealant remover. Method: first test on an inconspicuous area to confirm it will not damage the coating or enamel. Dip a cotton swab in the solvent, apply it to the sealant, let it sit for 1–2 minutes, then wipe it away once the sealant swells. Our glass factory reminds you: acetone has strong dissolving power but is flammable and irritating, so use it with ventilation; alcohol is milder and suitable for home use. If the sealant bead is thick, shave it thin with a blade first, then apply the solvent. 4. Precautions for Different Types of Glass Ordinary clear glass is resistant to acids and alkalis, so there is more room for cleaning. Tempered glass is sensitive to localized high temperatures, so do not use open flame. Coated glass and Low-E glass are sensitive to friction and strong solvents, so only neutral cleaners and soft cloths should be used. Laminated glass edges are sensitive to water, so solvents should not flow freely. Our glass factory establishes cleaning specifications for different coating layers during deep processing, and home users should also "treat each material according to its nature." 5. Prevention Is More Important Than Removal Before applying sealant, tape masking paper along the edge of the glass. After the sealant cures, peel it off to reduce residue. If sealant has already gotten on the glass, the sooner it is treated, the easier it is. Our glass factory sums it up: physical first, then chemical; mild first, then strong; edges first, then center. These are the general principles for safely removing silicone sealant from glass. Master these methods, and you too can restore your glass to a clear, clean finish, just like the craftsmen at a glass factory.
