Double Glazing Door Locks Many homeowners opt for double glazed doors and windows for their insulation as well as energy efficiency and noise reduction. They are also a powerful deterrent for burglars. To ensure the security of your double-glazed windows, check that they have been fitted with anti-jemmy hinges. These specialised hardware parts make it very difficult to open the window sashes open. Multi-point locking Multipoint door locks can be one of the most effective security devices that you can install at your workplace or at home. They are almost impossible for anyone to break or pick, and are a great addition to any security system. They can also improve your energy efficiency by reducing drafts as well as improving the seal around the door frame. Multi-point locking systems consist of a deadbolt, live bolt and hook bolts that are above and below the latch. They also include flush bolts that secure the door's head and the sill. They generally extend most of the time, but not all across the entire width 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 are equipped with multi-point locking, however certain timber doors are available with this level of security. This kind of lock offers a higher level of security when compared to regular locks. It is typically mentioned as part of the Secured by Design initiative, which has been approved by the police. When a uPVC door with a multi-point lock has been closed the handle on the outside operates the latch bolt. The inside handle is locked by turning the thumbturn lock on the inside with the door handle raised or using keys. Always use a key to lock your door. Utilizing handles to lock the door can damage the latch or deadbolt. If your uPVC multi-point lock isn't working properly it could be due to it's misaligned with the door frame. You can test this by placing a spirit-level on top of the doors, and then looking for gaps at the miter joints. If you notice an opening you're looking for, contact your double glazing specialist to look at the issue and resolve the issue. They can either replace the lock or install a replacement. They'll be able to determine whether it's due to damage on the frame or lock unit. In these cases the technician can repair or replace the multipoint lock in order to restore it's functionality. Espagnolette locks Espagnolette locks have become a standard locking mechanism for double-glazed uPVC windows. The flat strip shape that rotates when you turn the handle is a great way to recognize them. They work with multi-point locks around the frame of your window to lock and unlock it securely. If you are looking to improve your uPVC windows, handles made of espagnolette are a great option for either new builds or renovations. They are available in a wide variety of styles, including contemporary and period. They also offer a wide variety of bar sizes backset options, the height of the mushroom cam and a selection of profiles to suit any need. The espagnolette lock is a popular choice, but it's been criticized for offering the lowest level of security on French doors. Having a single point of locking in the middle of the door is easily removed with sufficient force. It is also quite easy for burglars to open your French doors by forcing the handle to either the left or right. These doors are typically used as a main entrance to your home. They should be kept secure to minimize the risk of intrusion by a stranger. In spite of their name, espagnolette locks aren't bolts they are actually a one-piece mechanism that fits externally onto the outside of your French doors or internally on the frame of a casement window. The mechanism is operated via a handle and comprises of a rod that has hooks at the sill and head that are inserted into sockets on the window frame. When the handle is operated the rod is moved upwards and downwards, and the hooks lock into their receivers to secure and unlock your windows. They are a great option for those looking to improve the security of their French doors without compromising the aesthetics of the door or the overall appearance of the room. The handles are available in a variety of styles and can be master-keyed for extra peace of mind. Similar to cockspur handles, espagnolette handles are available in both inline and crank models depending on the orientation of your windows. double glazing window lock replacement turn in the same manner as the original, while the cranked versions are available in both left and right handed options. Laminated glass Laminated glass is often used in windows because it is extremely hard to break. It is also more secure than regular safety glass since it is fused to a single piece rather than breaking into sharp fragments. This makes it ideal for homes and commercial buildings. Lamination is the process of joining two pieces flat glass and an interlayer of plastic. The entire piece is heated before being pressured to make it stronger enough to be used as a door or window. The laminated glass that is created is five times stronger and a hundred times more rigid than tempered. It also can endure more severe impacts, and resist weathering. This type of glazing is ideal for construction sites that require high performance, such as increased safety (impact resistant glass) and UV protection, as well as noise reduction. Laminated glazing can be used with a high-performance coating in order to increase thermal insulation and solar control. It is available in a variety of options to suit your budget and project. Laminated glass is more secure to use than tempered glass as it is able to be cut even after the production. 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 choice for glass that cannot open or close, like cellar windows. It is also used in high-rise buildings in urban areas because it can reduce the amount of noise that travels from the street to the interior. The Saflex PVB layer in the laminated glasses also helps to block harmful sun ultraviolet radiations. This prevents discoloration of fabrics, furniture and other objects. Although laminated glazing is typically more expensive than glass that has been tempered, it comes with many advantages that can save you money in the long run. It's also more robust, resistant to abrasion and scratches, and can be made to your specifications. In addition, it's less susceptible to heat damage and is a great choice for coastal areas and high-rise buildings. Some building codes even require that exterior doors and certain interior windows are made of glass laminated. Friction hinges Friction hinges are designed to support and maintain the position of doors and flaps, panels and windows. They also impede the movement of other hinges and prevent the slamming of a heavy object or accidental closing and opening. They are available in a variety of shapes and sizes. They also be fitted with different torque levels that are the forces which determine how long the hinges remain open or closed. Aluminum is a fantastic material for friction hinges because of its strength, durability, resistance to corrosion, and high strength-toweight ratio. It is also lightweight and easy to work with. It is also able to be made into a wide range of finishes and is easy to install and repair. Another popular material for friction hinges is brass. Brass is an alloy made of copper and zinc, and it is naturally resistant to corrosion. It is more durable and stronger durable than stainless steel, but is more expensive. The friction hinges that are utilized in uPVC double glazing door systems can be tailored to meet the requirements of the particular application. These modifications may include the amount of damping, the viscosity of lubricant, and the degree of tolerance between the components. They could also include the environmental conditions that the hinge will be used. These factors can affect the dynamic torque of hinges. It is essential to be aware of the metric when in critical applications. There are many different types of friction hinges. These include one-way and detent. Detent friction hinges do not have torque in the opposite direction. Other variations include disc, curl and pipe friction. Every type of friction hinge is unique and has its own set of properties, which make it more or less suitable for certain situations. The friction hinges are often called “free stop” hinges because they permit doors or lids to remain at a fixed angle even after the force has been removed. This can help prevent injuries by preventing accidental closures. This type of hinge is ideal for use in harsh, medical or hazardous areas. The hinges are able to be designed to have different degrees of free play and can be designed to work in a range of angles.
