Double Glazing Door Locks Many homeowners choose double-glazed windows and doors to increase insulation, energy efficiency and sound reduction. They are also an effective deterrent to burglars. To ensure the security of your double-glazed windows, check that they are fitted with anti-jemmy hinges. These specialised hardware parts make it difficult to pry the sashes of your windows open. Multi-point locking Multipoint door locks can be one of the most effective security devices that you can put in your workplace or at home. They are nearly impossible to break or pick, and they can be an ideal option to add to any security system. They can also improve your energy efficiency by reducing drafts and enhancing the seal around the door frame. Multi-point locking systems comprise of a deadbolt and live bolt (latch) coupled with hook bolts above and below the latch, plus flush bolts that secure the sill and head of the door frame. They are usually extended across the entire length of the door, if not more. These systems are often referred to as “full-width”, in commercial contexts. They protect the entire opening of the door. Multi-point locking is available on most uPVC and some doors made of timber. This kind of lock provides an even higher security level than standard locks and will often be listed as part of a police-approved Secured by Design initiative for new construction homes. When a uPVC door with a multi-point lock has been closed the handle on the outside turns the latch bolt. replace window locks upvc can be locked by turning the thumbturn inside when the door handle is raised, or using a lock key. Always use a key when you lock your door. Utilizing handles to lock the door can damage the latch or deadbolt. If your uPVC lock isn't functioning correctly, it could be that it is not aligned with the door frame. You can test this by placing a spirit-level on top of the doors and looking for gaps at the miter joints. If you do find an opening you're looking for, contact your double glazing expert to take a look and resolve the issue. They can replace the lock or install a new one. They'll be able to tell whether it's due to damage on the frame or the lock unit. In these cases, the technician will be able to repair or replace the multipoint lock in order to get it working again. Espagnolette locks Espagnolette locks are one of the most commonly used window locking mechanisms that are used for modern uPVC double-glazed windows. They can be identified by their flat strip design which moves as you turn the handle. They work in harmony with secure multi-point locks placed around the frame to firmly secure and unlock your windows. If you are looking to upgrade your uPVC window handles, espagnolette handles can be used for new builds or renovations. They are available in a range of styles, both contemporary and period, and come in a range of bar lengths, backset options and mushroom cam heights with a variety of profile keeps to suit all kinds of applications. While they are a popular choice however, espagnolette locks have also been criticized for providing low levels of security to French doors. Having a single point of locking at the center of the door can 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 doors are typically used as the primary entry point to your home, and should be kept secure to reduce the chance 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 edges of your French doors or internally on the frame of a casement window. The mechanism is operated with a handle. It is comprised of a rod which has hooks at its sill and head. These hooks fit into sockets on the window frame. When the handle is operated, the rod is moved between up and down, and the hooks are locked into their receivers, allowing them to lock and unlock your windows. These are a great solution for those looking to improve the security of their French doors without compromising the aesthetics of the door or the overall design of the room. These handles are compatible with a variety of different styles and can even be master keyed to give you added security. Similar to cockspur handles, espagnolette handles are available in both crank and inline models based on the orientation of your windows. Inline versions turn the same way as the original handle, whereas Cranked versions are available in both left and right handed options. Laminated glass Laminated glass is typically used in windows because it is extremely hard to break. It is also more secure than regular safety glass since it is fused into a single piece rather than breaking into sharp fragments. This makes it ideal for both residential and commercial properties. Lamination is a process which involves the joining of two pieces of flat glass with a plastic layer in between. The entire piece is heated and then put under pressure to make it stronger enough to be used as the construction of a door or window. The laminated glass that results is up to five times stronger and one hundred times more rigid than the glass that is tempered. It also can endure more severe impacts, and resist weathering. This type of glass is ideal for buildings that have to perform well, such as enhanced security (impact-resistant glass), UV protection, or noise reduction. Laminated glass can be paired with high-performance coatings to improve the thermal insulation as well as solar control. It's available in a wide range of options to fit your needs and budget. As opposed to tempered glass glass can be cut after production and still be safe to use. It is less likely to break if it's cut from the sides of the glass rather than the edge. 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 structures. The Saflex PVB layer within the laminated glasses is also able to absorb the sun's damaging ultraviolet rays. This prevents discolouration of furniture, fabrics and other things. Although laminated glass is typically more expensive than glass that is tempered, it has multiple benefits that can save you money over the long term. It's also more durable and resistant to scratches and abrasions. It can be created according to your exact specifications. It's also less susceptible to heat damage, making it an ideal choice for coastal areas or high-rise buildings. In fact, certain building codes require that all exterior doors and certain interior windows be made from laminated glass. Friction hinges Friction hinges help hold in place doors as well as flaps and panels. They can also resist the motion of other hinges and stop hard slamming or unintentional opening and closing. They are available in various sizes and shapes. They can be fitted with different torque levels which 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, durability, resistance to corrosion, and high strength-toweight ratio. It is also light and easy to handle. It is also able to be made into a wide variety of finishes, and is easy to set up and repair. Another popular material for friction hinges is brass. Brass is an alloy comprised of zinc and copper. It is a natural resistance 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 the specific requirements of the particular application. These modifications can include the amount of damping, the lubricant viscosity, the degree of tolerance for space between components, as well as the environment in which the hinge will be used. These factors can impact the dynamic torque of the hinge and it is important to monitor this metric when it comes to critical applications. There are a variety of friction hinges. These include one-way and detent. One-way friction hinges have constant torque in one direction, while detent friction hinges don't have any torque in the opposite direction. Other variations include disc, curl, and pipe friction. Each type of friction hinge has a unique set of properties that make it more or less effective in specific applications. The friction hinges are often called “free stop” hinges because they allow a lid or door to remain at a predetermined angle after the force has been removed. This helps prevent injuries through accidental closing. This type hinge is ideal for harsh, medical or dangerous areas. The hinges can be configured to have different degrees of free play and can be made to work in a range of angles.
