Double Glazing Door Locks Many homeowners choose double-glazed windows and doors due to their energy efficiency, insulation and sound reduction. However, they are also an effective deterrent against burglars. Check that your double-glazed windows have anti-jemmy hinges to improve their security. These hardware components are specially designed to make it extremely difficult to pry open window sashes. Multi-point locking Multipoint door locks are among the most effective security devices you can put in at home or at work. They are virtually impossible for anyone to break or pick, and can be a fantastic addition to any security system. They can also boost the efficiency of your energy by reducing drafts as well as improving the seal around the door frame. Multi-point locking systems comprise of a deadbolt and live bolt (latch) paired with hook bolts below and above the latch, and flush bolts that are locked into the head and sill of the door frame. They generally extend most of the time, but they are not all across the width of the door. In commercial contexts, these are referred to as “full-width” systems because they secure the entire door opening. 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 provides an increased security level than standard locks and will often be specified as part of an approved by the police Secured by Design initiative for new homes. When a uPVC door with a multi-point lock has been closed, the outside handle operates the latch bolt. The inside handle is locked by turning the lock's thumbturn on the inside with the door handle raised or using keys. You should always use keys to lock your door once it's closed, as trying to force the deadbolt or latch bolt with a handle may damage the lock and the hinges. If your uPVC lock is not working properly, it could mean that it's not aligned with the door frame. You can check this by placing a spirit level on top of the door and looking for gaps in the miter joints where the frame meets the door. If you find an opening, it's worth getting your double glazing specialist to have 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 tell if it's caused by damage to the frame or lock unit. In such cases, the technician will be able repair or replace the multipoint lock to get it working again. Espagnolette locks Espagnolette locks are now a standard locking mechanism for double-glazed uPVC windows. They can be identified by their flat strip shape that rotates when you turn the handle. They work with multi-point locks that are placed around the frame of your window to secure the window and lock it. If you're looking to improve your uPVC windows, espagnolette handles are an ideal option for either new builds or renovations. They come in a wide selection of styles, from period and contemporary. They also have an array of bar sizes, backset options, mushroom cam heights and a variety of profiles that can be used for any application. The espagnolette lock is a well-liked option, but it has been criticized for delivering a low level of security for French doors. A single lock point in the middle of the door is easily bypassed. In addition, it is fairly easy for thieves to open your French doors by forcing the handle to either the left or right. These types of doors are usually used as a principal entrance to your home. They should be kept secure to reduce the chance of unauthorized entry. Despite their name, espagnolette locks are not a bolt they are actually a one-piece mechanism that can be mounted externally on the outside of your French doors or inside the frame of a casement window. The mechanism is operated by an handle. It consists of a rod which has hooks at its sill and head. These hooks fit into sockets in the window frame. When the handle of the window is operated, it moves the rod upwards and downwards. The hooks are then locked into their respective receivers. They are a great option for those looking to increase the security of their French doors without compromising the aesthetic of the door or the overall look of the room. The handles are available in a variety of styles and can be master-keyed for extra peace of mind. Just like cockspur handles, the espagnolette handle designs are available both cranked and inline models to suit the orientation of your window. Inline versions simply turn exactly the same way as the original, whereas the cranked versions are available in both left and right handed options. Laminated glass Laminated glass is commonly used for windows since it is extremely difficult to break. window lock repairs Repair My Windows And Doors is also safer than regular safety glass since it is fused into a single piece rather than breaking into sharp shards. This makes it ideal for residential and commercial buildings. Lamination is the process of combining two pieces flat glass and an interlayer of plastic. The whole piece is then heated and placed under pressure to make it strong enough for a window or door. The laminated glass created can be up to five times stronger and a hundred times more stiff than tempered. It also withstands more intense impacts and resists weathering. This kind of glass is perfect for buildings that need to perform well, like enhanced security (impact-resistant glass) UV protection, or noise reduction. Laminated glass is able to be combined with high-performance coatings that improve the thermal insulation as well as solar control. It is available in a range of options to fit your budget and project. Laminated glass is safer to use than tempered glass because it is cut after the fact. It is also less likely to break when cut from the side instead of the edge the glass. This makes it a great option for glass that cannot open or close, like cellar windows. It is also used to reduce the noise that travels through high-rise buildings. The Saflex PVB interlayer within the laminated glass is also able to suffocate some of the sun's damaging UV rays, which prevents discoloration of furnishings and fabrics. Although laminated glass is more expensive than tempered, it offers many advantages that will help you save money over time. It's also more durable and resistant to scratches and abrasions. It can be made according to your exact specifications. It's also less susceptible to heat damage, making it a great option for coastal areas and high-rise buildings. In fact, certain building codes require that all exterior doors as well as some interior windows be made from laminated glass. Friction hinges Friction hinges help hold in place doors as well as flaps and panels. They also impede the movement of other hinges and stop an unintentional closing and opening. They are available in various dimensions and shapes, and are able to have a variety of torques. These forces determine how long hinges stay open or closed. Aluminum is a great material for friction hinges because of its high strength-to-weight ratio as well as its durability and corrosion resistance. It is light and easy to handle. It is also able to be made into a wide variety of finishes, and is simple to install and repair. Brass is another material widely used for friction hinges. Brass is an alloy made of copper and zinc, and it has a natural resistance to corrosion. It is also more durable and stronger durable than steel, however it is more expensive. The hinges that use friction in uPVC doors with double glazing can be modified depending on the purpose for which they are intended. These customizations may include the amount of damping, the lubricant viscosity, the degree of tolerance to space between components, and conditions in which the hinge will be used. These factors can affect the dynamic torque of a hinge. It is crucial to be aware of the metric when in critical applications. There are different types of friction hinges including detent and one-way. One-way friction hinges are characterized by constant torque in one direction, while detent friction hinges do not have torque in the opposite direction. Other variations include curl, disc, and pipe friction. Each type of friction hinge has a unique set of characteristics that make it more or less useful in specific applications. The friction hinges are often called 'free stop' hinges, because they permit doors or lids to remain at a fixed angle after the force has been removed. This can help prevent injuries by preventing accidental closures. This kind of hinge is perfect for medical, rugged or hazardous locations. The hinges can be configured to provide different degrees of free play, and can be made to function at different angles.
