Double Glazing Door Locks Many homeowners opt for double-glazed windows and doors due to their energy efficiency, insulation and sound reduction. But, they also serve as an effective deterrent to burglars. To ensure the security of your double-glazed windows, check that they are fitted with anti-jemmy hinges. These special hardware components make it extremely difficult to open the sashes of your windows open. Multi-point locking Multipoint door locks are one of the most reliable security devices you can install in your home or workplace. They are almost impossible to break or pick and can be an ideal addition to any security system. They can also increase your energy efficiency by reducing drafts as well as improving the seal around the door frame. Multi-point locking systems are composed of a deadbolt, a live bolt, and hook bolts above and beneath the latch. They also include flush bolts that lock into the door's head and the sill. They generally extend most of the time, but not all the way across the length of the door. These systems are referred to as “full-width”, in commercial contexts. They protect the entire opening of the door. The majority of uPVC doors have multi-point locking, however some timber doors are also available with this level of security. This kind of lock provides an increased security level than conventional locks and can be specified as part of a police-approved Secured by Design initiative for new homes. When a uPVC multi-point lock door is closed, the outside handle activates the latch bolt. The inside handle can be locked by turning the thumbturn on the inside while 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 could damage the latch or deadbolt. If your uPVC lock isn't functioning properly, it could be that it is not aligned with the frame of the door. You can test this by placing a spirit-level over the top of the doors and observing for gaps in the miter joints. It is worth consulting your double glazing specialist if there is a gap and to fix it. They'll be able replace the lock for you or fit a replacement. They'll know whether the issue is caused by damage to the frame or the lock unit itself. In such cases they'll be able repair or replace your multipoint lock to make it work again. Espagnolette locks Espagnolette locks are one of the most commonly used window locking mechanisms for modern uPVC double-glazed windows. They are easily recognised by their flat strip shape which moves as you turn the handle. They are used 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 window handles, espagnolette handles can be utilized for new constructions or renovations. They are available in a wide variety of styles, including modern and traditional. They also offer many bar sizes and backset options, as well as the height of the mushroom cam and a selection of profiles to suit every application. Although they are a very well-liked option the espagnolette locks have been criticized for providing inadequate security for French doors. The single point of locking in the center of the door is easily removed with sufficient force. It is also possible for thieves to open French doors by pushing the handle to the right or left. These types of doors are often used as the main entry point to your home, and should be kept secure to minimise the risk of intrusion by a stranger. Despite their name, espagnolette locks aren't bolts they are actually a one-piece mechanism that is able to be fitted externally on the edges of your French doors or internally on the frame of a casement window. The mechanism is operated by an handle. It is made up of a rod which has hooks at its head and the sill. The hooks are inserted into sockets on the window frame. When the window's handle is turned on the rod is moved upwards and downwards. The hooks are then locked into their respective receivers. These are a great solution for those who want to improve the security of their French doors without compromising the aesthetics the door or the overall look of the room. These handles can be used in various styles and are able to be master-keyed to provide extra peace of mind. Like cockspur handles espagnolette handles are available in both inline and cranked models to suit the orientation of your window. Inline versions turn the same way as the original handle, whereas cranked versions are available in both left and right handed versions. Laminated glass It is often used as a window because it is extremely difficult to break. It is also safer than standard safety glass as it is fused to a single piece rather than breaking into sharp shards. This makes it perfect for both residential and commercial properties. Lamination is the process of combining two pieces of flat glass with an interlayer of plastic. The whole piece is then heated and placed under pressure to make it stronger enough for a window or door. The laminated glass that is created can be up to five times stronger and one hundred times more stiff than tempered. It also withstands more intense impacts and is resistant to weathering. This kind of glazing is perfect for use in buildings that require demanding performance like increased safety (impact resistant glass), UV protection or noise reduction. window and door lock repair can be paired with high-performance coatings to improve both solar and thermal control. It is available in a variety of options to suit your project and budget. Laminated glass is safer to use than tempered glass since it is cut even after production. It is also less likely to break when cut from the sides instead of the edge of the glass. This makes it a great option for glass that does not open or close, such as cellar windows. It also helps reduce the sound that travels through high-rise buildings. The Saflex PVB interlayer in the laminated glass helps to suffocate some of the sun's harmful UV rays, which prevents discoloration of fabrics and furnishings. Although laminated glass is more expensive than tempered, it offers many advantages that will reduce your costs over time. It's also more durable and resistant to abrasions and scratches. It can be created to meet your specific requirements. Additionally, it's less susceptible to heat damage, and is a great option for high-rise and coastal areas. In fact, some building codes require that all exterior doors as well as some interior windows are made of laminated glass. Friction hinges Friction hinges are used to support and hold doors panels, flaps and doors. They also can withstand the movement of other hinges and stop hard slamming as well as accidental closing and opening. They are available in various sizes and shapes. They can have different torques that are the forces which determine how long the hinges will stay open or closed. Aluminum is a fantastic material for friction hinges due to its strength, durability, resistance to corrosion and high strength-to-weight ratio. It is also light and easy to handle. It can also be made into a wide range of finishes and is easy to install and repair. Brass is another material widely used for friction hinges. Brass is an alloy comprised of copper and zinc. 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 door systems with double glazing can be customized depending on the purpose for which they are intended. These adjustments could include the amount of damping, the viscosity of the lubricant and the degree of tolerance between the components. They can also be influenced by the environmental conditions that the hinge is used. These factors can impact the dynamic torque of the hinge, and it is important to keep track of this metric in critical applications. There are a variety of friction hinges, including detent and one-way. Detent friction hinges do not have torque in the opposite direction. Other variations include discs, pipe, and curl friction. Every type of friction hinge is distinct and has its own set properties that make it more or lesser useful for certain applications. The friction hinges are often called “free stop” hinges because they permit a lid or door to remain at a fixed angle after the force is removed. This protects against injuries by preventing accidental closing. This kind hinge is ideal for medical, rugged or dangerous areas. The hinges are configurable to provide different degrees of free play, and can be made to function in different angles.
