Double Glazing Door Locks Many homeowners opt for double-glazed windows and doors for their insulation, energy efficiency, and sound reduction. They are also an effective deterrent to burglars. To enhance the security of your double glazed windows, make sure they are fitted with anti-jemmy hinges. These specialised hardware components make it difficult to open window sashes. Multi-point locking Multipoint door locks are one of the most reliable security tools you can install at home or at work. They are virtually impossible to break or pick, and they can be an ideal addition to any security system. window door repairs locks glass hinges RepairMyWindowsAndDoors can also improve the efficiency of your energy use by reducing drafts around the doorframe and improving the seal. Multi-point locking systems are comprised of a deadbolt and live bolt (latch) joined by hook bolts above and below the latch, plus flush bolts that are locked into the head and sill of the door frame. They are usually extended across the entire width of the door, if not more. In commercial contexts, these are referred to as “full-width” systems, because they are able to secure the entire opening. Multi-point locking is offered on most uPVC and some timber doors. This type of lock provides a higher level of security compared to standard locks. It is typically mentioned as part of the Secured by Design initiative, that has been approved by the police. When a multi-point uPVC lock door is shut and the outside handle is turned on, it opens the latch bolt. The inside handle is locked by turning the lock's thumbturn inside of the door with the handle raised or by using the key. It is recommended to use a key to lock your door once it is closed, since trying to push the deadbolt or latch bolt with a handle may damage the lock as well as the hinges. If your uPVC multi-point lock isn't functioning properly it could be because it's misaligned with the door frame. You can test this by placing a spirit level on the top of the door and checking for any gaps in the miter joints, where the frame connects to the door. If you find an opening it's worth contacting your double glazing specialist to have a look and repair the issue. They'll be able to repair 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 will be able repair or replace the multipoint lock to restore it's functionality. Espagnolette locks Espagnolette locks have become a standard locking mechanism for double-glazed uPVC windows. They can be identified by their flat strip shape which moves as you turn the handle. They work with multi-point locks around the frame of your window to lock and unlock it securely. If you are seeking to improve your uPVC windows, espagnolette handles are an ideal choice for new constructions or renovations. They are available in a range 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 profile keeps to suit most applications. Although a very popular choice, espagnolette locks have been criticized for providing inadequate security for French doors. Having a single point of locking in the middle of the door could be overcome with enough force. It is also possible for burglars to open French doors by pushing the handle to the left or left. These types of doors are usually used as a primary entrance to your home and must be secured to minimize the risk of intrusion by a stranger. Although they are referred to as espagnolette locks, these locks are not a bolt but a single piece mechanism that fits externally onto the outside of your French doors or inside a frame for a casement window. The mechanism operates with the help of a handle. It consists of a rod with hooks at its sill and head. These hooks fit into sockets on the window frame. When the handle is turned, the rod is moved upwards and downwards, and the hooks are locked into their receivers, allowing them to lock and unlock your windows. These are an excellent solution for those who wish to improve the security of French doors without compromising on the aesthetics of the door. These handles are compatible with a variety of different styles and can be master keyed for added security. Similar to cockspur handles espagnolette handles are available in both cranked and inline versions to suit the orientation of your window. Inline versions turn exactly the same way as the original handle, whereas cranked versions are available in both right and left handed designs. Laminated glass It is used as windows because it is very hard to break. It is also more secure than standard glass because it is a single piece of safety glass, rather than breaking into sharp, loose shreds. This makes it ideal for both residential and commercial properties. Lamination is a process that combines two pieces of flat glass with a plastic layer in between. The entire piece is heated and pressured to make it stronger enough to be used as a door or window. The resulting laminated glass is 5 times stronger and 100 times more rigid than glass that has been tempered. It also can endure more severe impacts, and resist weathering. This kind of glazing is ideal for buildings that require demanding performance like increased safety (impact resistant glass) UV protection or noise reduction. Laminated glass can be paired with high-performance coatings to enhance the thermal insulation as well as solar control. It is available in a range of options to suit your project and budget. Laminated glass is more secure to use than tempered glass because it is cut even after production. It is less likely to break if it's cut from the sides of the glass instead of the edge. This makes it a good option for glass that won't open or close like cellar windows. It also helps reduce the sound that travels through high-rise buildings. The Saflex PVB layer within the laminated glasses also helps to block harmful sun ultraviolet radiations. This prevents discolouration of furniture, fabrics, and other items. Although laminated glass is typically more expensive than glass that has been tempered, it comes with many advantages that can save you money over the long term. It's also more robust and resistant to abrasions and scratches, and can be made to your exact specifications. It's also less prone to heat damage, and is an ideal choice for coastal areas and high-rise buildings. Certain building codes require that exterior doors and some interior windows are made of laminated glass. Friction hinges Friction hinges are designed to hold and support the position of doors and flaps, panels and windows. They also can withstand other hinges' motion and stop hard slamming and accidental opening and closing. They come in a variety of sizes and shapes, and they 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 because of its durability, corrosion resistance and high strength-to-weight ratio. It is light and easy to handle. It is also available in various colors, and it's simple to set up and fix. Brass is another popular material that is used in friction hinges. Brass is an alloy of zinc and copper and is naturally resistant to corrosion. It is also stronger and more durable than steel, however it is more expensive. The friction hinges used in uPVC doors with double glazing are able to be customized in accordance with the requirements of the particular application. These adjustments could include the amount of damping, lubricant viscosity and the degree of tolerance between components. They could also include the environmental conditions where the hinge will be utilized. These variables can affect the dynamic torque of a hinge. It is crucial to monitor the metric in critical applications. There are various kinds of friction hinges such as one-way and detent. One-way friction hinges are characterized by constant torque in one direction, whereas detent friction hinges have no torque in the opposite direction. Other variations include disc, pipe and curl friction. Every type of friction hinge is distinct and comes with its own set of properties that make it more or less suitable for certain situations. The hinges that are friction are commonly called “free stop” hinges because they permit the lid or door to remain at a fixed angle even after the force is removed. This helps to prevent injuries through preventing accidental closures. This kind of hinge is perfect for harsh, medical or dangerous areas. The hinges can be configured to have different degrees of free play and are able to function in a variety of angles.
