Double Glazing Door Locks Many homeowners choose double-glazed doors and windows for their energy efficiency, insulation and sound reduction. However, they are also an effective deterrent against burglars. To enhance the security of your double-glazed windows, ensure that they have been equipped with anti-jemmy hinges. These specialised hardware components make it extremely difficult to get windows sashes. Multi-point locking Multipoint door locks are among the most reliable security devices you can put in at home or at work. They are almost impossible to pick or break and can be an ideal addition to any security system. They also can improve your energy efficiency, by cutting down on drafts in the doorframe and improving the seal. Multi-point locking systems comprise of a deadbolt and a live bolt (latch) joined by hook bolts that are above and below the latch, and flush bolts that secure the head and sill of the door frame. They usually extend most if they are not all across the entire length of the door. These systems are known as “full-width”, in commercial contexts. They secure the entire opening of the door. The majority of uPVC doors have multi-point locking, but certain timber doors are equipped with this level of security. This type of lock offers an even higher security level than conventional locks and can be listed as part of a police-approved Secured by Design initiative for new homes. If a uPVC door that has a multi-point lock is shut the handle on the outside turns the latch bolt. The inside handle is locked by turning the lock's thumbturn inside with the door handle raised or using keys. Always use a key to lock your door. The use of handles to lock the door could cause damage to the latch or deadbolt. If your uPVC lock isn't functioning properly, it could mean that it's out of alignment with the door frame. You can check by placing a spirit level on top of the doors and observing for gaps in the miter joints. If you find an opening, it's worth getting your double glazing expert to take a look and fix the problem. They'll be able to repair the lock for you or fit a replacement. They'll be able to determine if the problem is due to damage to the frame or the lock unit itself. In these cases the technician will be able to repair or replace the multipoint lock to get it working again. Espagnolette locks Espagnolette locks are one of the most popular window locking mechanisms that are used for modern uPVC double glazed windows. The shape of the flat strip that rotates when you turn the handle is a great method to identify them. They work in conjunction with secure multi-point locks placed around the frame to securely lock and unlock your windows. If you are seeking to upgrade your uPVC windows, handles made of espagnolette are a great option for new builds or renovations. They are available in a variety of styles, both contemporary and period, and come in a variety of bar lengths, backset options and the heights of the mushroom cams, with a variety of a profile that will suit most applications. The espagnolette lock is a popular option, but it has been criticized for offering a low level of security for French doors. With only one point of locking at the center of the door can be overcome with enough force. Additionally, it is relatively easy for thieves to open your French doors by forcing the handle to either the left or right. These doors are typically the main entry points into your home, and must be secured to limit the chance of unauthorized intrusion. Despite their name, espagnolette locks aren't bolts but a single piece mechanism that fits externally onto the edges of your French doors or inside a casement window frame. The mechanism is operated by a handle, and consists of a rod that has hooks at the head and sill that fit into sockets in the window frame. When the handle of the window is turned on the rod is moved upwards and downwards. The hooks then lock into their respective receivers. These are a great solution for those who want to improve the security of their French doors without compromising the aesthetic of the door or the overall design of the room. These handles can be used in a variety of styles and can be master-keyed for added security. Similar to cockspur handles the espagnolette handle designs are available both inline and cranked models to fit the shape of your window. Inline versions rotate in the same direction as the original. Cranked versions come in both right- and left-handed versions. Laminated glass Laminated glass is commonly used for windows as it is extremely hard to break. It is also safer than regular glass since it is fused into a single piece of safety glass, rather than breaking into sharp, loose shreds. This makes it perfect for homes and commercial buildings. Lamination is a process that involves the joining of two pieces of glass with a plastic interlayer in between. The whole piece is then heated and placed under pressure to make it stronger enough to be used as a window or door. The resulting laminated glass is five times stronger and 100 times more rigid than glass that is tempered. It also withstands stronger impacts and resists weathering. This kind of glass is perfect for buildings that have to perform well, such as enhanced safety (impact-resistant glass) and UV protection or noise reduction. Laminated glass can be combined with high-performance coatings that improve both solar and thermal control. It comes in a range of options that will fit your needs and budget. As opposed to tempered glass glass is able to be cut after production, and be safe to use. It is more likely to not shatter when cut from the sides instead of the edge of the glass. This makes it a good choice for glass that doesn't open or close like cellar windows. It is also used in high-rise structures in urban areas because of its ability to reduce the amount of noise that flows from the street to the interior of the. The Saflex PVB layer within the laminated glasses is also able to absorb the sun's damaging ultraviolet rays. This prevents discoloration of fabrics, furniture and other items. Although laminated glass is more expensive than tempered, it has many benefits that can help you save money over time. It's also more durable and resistant to abrasions and scratches and can be customized according to your specific requirements. It's also less prone to heat damage, making it a great option for coastal areas and high-rise structures. In fact, some building codes require that all exterior doors and certain interior windows be made from laminated glass. Friction hinges Friction hinges are designed to hold and support the positions of doors and flaps, panels and windows. They also can withstand the movement of other hinges, and also prevent hard slamming or unintentional closing and opening. They are available in various dimensions and shapes, and can be equipped with a variety torques. These forces determine how long hinges stay open or closed. Aluminum is a fantastic material for friction hinges due to its durability, corrosion resistance, and high strength-toweight ratio. It is also lightweight and easy to work with. It is also able to be made into a range of finishes and is simple to install and repair. Another popular material for friction hinges is brass. Brass is an alloy made of copper and zinc. It is naturally corrosion resistance. It is more durable and stronger durable than stainless steel, but is more expensive. The hinges made of friction used in uPVC doors with double glazing can be customized according to the application. These adjustments can include the amount of damping, the lubricant viscosity and the amount of tolerance for space between components, as well as the environment in which the hinge is used. upvc window lock repair RepairMyWindowsAndDoors can affect the dynamic torque of hinges. It is essential to keep track of the metric in crucial applications. There are a variety of friction hinges including detent and one-way. One-way friction hinges have constant torque in one direction, whereas detent friction hinges don't have any torque in the opposite direction. Other variations include disc, curl and pipe friction. Each type of hinge is distinct and comes with its own set of properties, which make it more or less useful for certain applications. Friction hinges are also known as hinges with a free-stop because they permit doors or lids to remain at an angle even after the force has been eliminated. This helps to prevent injuries due to accidental closures. This type hinge is ideal for use in medical, tough or dangerous environments. The hinges can be set to provide different levels of free play and can be designed to function in a variety of angles.
