Double Glazing Door Locks Many homeowners choose double-glazed windows and doors to increase insulation and energy efficiency as well as sound reduction. They are also a powerful deterrent to burglars. To enhance the security of your double-glazed windows, make sure they are equipped with anti-jemmy hinges. These specialised hardware components make it extremely difficult to get windows sashes. Multi-point locking Multipoint door locks can be one of the most effective security devices you can put in your office or home. They are nearly impossible to break or pick, and can be a fantastic option to add to any security system. They can also improve your energy efficiency by reducing drafts and improving the seal around the door frame. Multi-point locking systems are comprised of a deadbolt and a live bolt (latch) coupled with hook bolts that are above and below the latch, as well as flush bolts that secure the head and sill of the door frame. They typically extend the most, if they are not all across the width of the door. In commercial settings, they are known as “full-width” systems because they secure the entire door opening. Multi-point locking is a feature on the majority of uPVC and some timber doors. This kind of lock offers an increased level of security than regular locks. It is often specified as part of the Secured by Design initiative, that has been approved by the police. If a uPVC door that has a multi-point lock is shut, the outside handle operates the latch bolt. The inside handle is locked by turning the lock's thumbturn inside, with the door handle raised or with a key. Always use a key to lock your door. Using a handle to lock your door could damage the latch or deadbolt. If your uPVC multi-point lock doesn't function properly, it could be because it's not aligned properly with the frame of the door. You can test this by placing a spirit-level over the top of the doors and looking for gaps in the miter joints. If you do find a gap it's worth contacting your double glazing expert to take a look and repair the issue. They'll be able to replace the lock for you or fit a replacement. They'll be able to determine whether the issue is caused by damage to the frame or lock unit. In these cases, the technician can repair or replace the multipoint lock to get it working again. Espagnolette locks Espagnolette locks have become a standard locking mechanism for double-glazed uPVC windows. The shape of the flat strip that changes when you turn the handle is a good method to identify them. They work with multi-point locks around the frame of your window to lock and unlock it securely. If you are looking to upgrade your uPVC window handles, espagnolette handles can be used to build new windows or renovations. They are available in a variety of styles, both contemporary and period, and are available in a variety of bar lengths, backset options and mushroom cam heights with a variety of a profile that will suit all kinds of applications. Although a very popular choice the espagnolette locks have been criticized for providing low levels of security to French doors. The single point of locking at the center of the door is easily removed with sufficient force. It is also possible for burglars to open French doors by pushing the handle to the right or left. These doors are typically used as a main entry point to your home, and should be kept secure to minimise the risk of intrusion by a stranger. Although they are referred to as espagnolette locks, these locks aren't bolts but actually a one-piece mechanism that is able to be fitted externally on the edge of your French doors or internally on a frame for a casement window. The mechanism is operated with a handle. It is made up of a rod which has hooks at its head and the sill. The hooks are inserted into sockets on the frame of your window. When the handle is operated the rod moves between up and down, and the hooks are locked into their receivers to lock and unlock your windows. These are a great solution for those who want to increase the security of their French doors without compromising the aesthetic of the door or the overall look of the room. These handles can be used in various styles and are able to be master-keyed for added peace of mind. Like cockspur handles espagnolette handles are available in both crank and inline models, based on the orientation of your windows. Inline versions operate exactly the same way as the original, while the cranked versions are available in both left and right handed versions. Laminated glass It is used as windows because it is extremely difficult to break. It is also more secure than regular glass since it is fused into a single piece of safety glass, rather than breaking into sharp, loose fragments. This makes it ideal for commercial and residential properties. Lamination is a method that involves the joining of two pieces of glass with a plastic interlayer between. The entire piece is heated and pressured to make it stronger enough to use as windows or doors. The laminated glass that results can be up to five times stronger and a hundred times stiffer than tempered. It is also able to withstand more intense impacts, and resist weathering. This kind of glazing is perfect for use in construction sites that require high performance for safety, such as increased security (impact resistant glass) UV protection or noise reduction. Laminated glazing can be used with a high-performance coating to increase thermal insulation and solar control. It's available in a wide range of options to fit your project and budget. As opposed to tempered glass glass is able to be cut after production, and be safe to use. It is less likely to break if it is cut from the sides of the glass, rather than the edge. This makes it a great option for glass that doesn't open or close like cellar windows. It is also used to reduce the sound that travels through high-rise buildings. helpful resources within the laminated glasses is also able to block sun's harmful ultraviolet radiations. This prevents discolouration of fabrics, furniture and other objects. While laminated glazing is generally more expensive than glass that has been tempered, it comes with multiple benefits that can save you money in the long run. It's also more robust and resistant to scratches and abrasions. It can be created to meet your specific requirements. Additionally, it's less prone to heat damage and is a great option for coastal areas and high-rise buildings. Some building codes even require that exterior doors as well as certain interior windows are made of glass laminated. Friction hinges Friction hinges help hold doors, flaps and panels. They can also impede the movement of other hinges and prevent hard slamming as well as accidental closing and opening. They are available in a variety of sizes and shapes and can have different torques that are the forces that determine how long hinges will stay open or closed. Aluminum is a fantastic material for friction hinges because of its strength-to-weight ratio that is high, durability, and resistance to corrosion. It is also light and easy to work with. It can also be crafted into a wide variety of finishes and is easy to install and repair. Brass is another material widely that is used in friction hinges. Brass is an alloy of copper and zinc which has a natural resistance to corrosion. It is also more durable and stronger durable than steel, but it is more expensive. The hinges made of friction used in uPVC double glazing door systems can be customized to the specific requirements of the particular application. These modifications may include the amount of damping, the viscosity of the lubricant and the degree of tolerance between the components. They could also include the environment where the hinge is used. These factors can impact the dynamic torque of hinges. It is essential to be aware of the metric when in critical applications. There are different types of friction hinges such as one-way and detent. Detent friction hinges do not have torque in the reverse direction. Other variations include disc, pipe, and curl friction. Each type of hinge is distinct and has its own set characteristics, making it more or less useful for specific applications. The hinges that are friction are commonly called “free stop” hinges because they permit doors or lids to remain at a predetermined angle after the force is removed. This prevents injuries by preventing accidental closing. This type hinge is ideal for harsh, medical or hazardous locations. The hinges can be configured to have different degrees or free play, and they can be designed to function in a variety of angles.
