Double Glazing Door Locks Many homeowners choose double-glazed windows and doors to increase insulation, energy efficiency and sound reduction. They are also a powerful deterrent to burglars. Make sure that the windows you have double-glazed are fitted with anti jemmy hinges to enhance their security. These special hardware components make it difficult to get windows sashes. Multi-point locking Multipoint door locks are one of the most secure security devices you can put in at home or at work. They are nearly impossible to pick or break, and can be a fantastic addition to any security system. They can also improve the efficiency of your energy by reducing drafts and enhancing the seal around the door frame. Multi-point locking systems are composed of a deadbolt and a live bolt, and hook bolts above and beneath the latch. They also include flush bolts which lock into the door's head and the sill. They usually extend most if not all across the entire width of the door. In commercial situations, they are referred to as “full-width” systems due to the fact that they secure the entire door opening. The majority of uPVC doors are equipped with multi-point locking, but certain timber doors are equipped with this level of security. This type of lock offers an even higher level of security than standard locks and will often be listed as part of an approved by the police Secured by Design initiative for new homes. When a uPVC multi-point lock door is shut the handle on the outside will activate the latch bolt. The inside handle can be locked by turning the thumbturn on the inside as the door handle is raised, or using a lock key. Always use the key to lock your door once it's closed. Attempting to push the deadbolt or latch bolt using a handle can damage the lock and the hinges. If your uPVC lock isn't working correctly, it could be that it's not aligned with the door frame. You can test this by placing a spirit level on the top of the door and looking for gaps in the miter joints at the point where the frame is joined to the door. It's worth asking your double glazing specialist whether there's a gap and to fix it. They'll be able replace the lock for you or install a replacement. They'll be able to determine whether the issue is caused by damage to the frame or lock unit. In this case they'll be able repair or replace your multipoint lock to restore it to its original state. Espagnolette locks Espagnolette locks have become a standard locking mechanism for double-glazed uPVC windows. They are easily recognised by their flat strip shape that rotates when you turn the handle. They are used using multi-point locks within the frame of your window to secure the window and lock it. If you're looking to upgrade your uPVC window handles, espagnolette handles can be used to build new windows or for renovations. They are available in a wide variety of styles, including period and contemporary. They also have an array of bar sizes backset options, mushroom cam heights and a choice of profiles to suit every application. The lock with a slat is a popular option, but it has been criticized for offering an inadequate level of security on French doors. The single point of locking at the center of the door could be overcome with enough 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 usually used as a main entrance to your home and must be secured to minimise the risk of unauthorized entry. The espagnolette lock does not function as a bolt, but a single-piece mechanism which can be fitted externally on the edges of French doors or internally to the frame of a casement. The mechanism is operated by a handle, and consists of a rod that has hooks at the head and sill which fit into sockets within the window frame. When the window's handle is operated it moves the rod up and down. The hooks then secure into their receivers. These are a great solution for those looking to increase 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 range of other designs and are able to be master keyed to give you added peace of mind. Like cockspur handles, espagnolette handle are available in both inline and crank models based on the orientation of your windows. Inline versions turn in the same direction as the original. Cranked versions come in both right-handed and left-handed options. Laminated glass Laminated glass is typically used in windows because it is extremely hard to break. It is also much safer than regular glass since it is a single piece of safety glass rather than breaking into sharp shards. This makes it ideal for homes as well as commercial properties. Lamination is the process of combining two pieces flat glass and an interlayer of plastic. The entire piece is heated and press-pressed to create a strong enough to use as a door or window. The resulting laminated glass is up to 5 times stronger and 100 times stronger than glass that has been tempered. It also withstands more intense impacts and is resistant to weathering. This type of glass is ideal for buildings that must perform well, such as enhanced safety (impact-resistant glass) and UV protection or noise reduction. Laminated glazing can be combined with a high-performance coating in order to improve thermal insulation as well as solar control. It's available in a variety of options to fit your project and budget. Laminated glass is more secure to use than tempered glass as it can be cut even after the production. It is less likely to break if cut from the sides of the glass, rather than the edge. This makes it a good option for glass that does not open or close, like cellar windows. It is also used in high-rise structures in urban areas due to its ability to reduce the volume of noise that is transmitted from the street to the interior. The Saflex PVB layer that is found in the laminated glasses also assists to block sun's harmful ultraviolet radiations. This helps prevent discoloration of furniture, fabrics and other things. Although laminated glass is more expensive than tempered, it comes with many advantages that will save you money over time. It is also more robust and resistant to scratches and abrasions. It can be manufactured to meet your specific specifications. Additionally, it's less prone to heat damage and is 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 of laminated glass. Friction hinges Friction hinges are designed to hold and support the positions of doors and flaps, panels and windows. They can also resist the movement of other hinges, and also prevent the slamming of a heavy object or accidental opening and closing. They are available in a variety of sizes and shapes. They can be fitted with different torque levels, which are the forces which determine how long the hinges remain open or closed. Aluminum is a great material for friction hinges due to its durability, corrosion resistance, and high strength-toweight ratio. It is also lightweight and easy to work with. It is also available in various finishes, and is easy to install and fix. Another popular material for friction hinges is brass. Brass is an alloy made of zinc and copper. It is a natural corrosion resistance. It is stronger and more durable than stainless steel, but is more expensive. The hinges made of friction used in uPVC door systems that have double glazing are able to be customized according to the application. Repair My Windows And Doors can include the amount of damping, the viscosity of the lubricant and the amount of space tolerance between components, as well as the conditions in which the hinge is used. These factors can affect the dynamic torque of the hinge and it is crucial to monitor this metric when it comes to critical applications. There are a variety of friction hinges. These include one-way and detent. Detent friction hinges do not have torque in the opposite direction. Other variations include curl, disc, and pipe friction. Each type of friction hinge is distinct and has its own set properties that make it more or lesser useful for certain situations. The hinges that are friction are commonly called “free stop” hinges because they permit a lid or door to remain at a predetermined angle after the force is removed. This prevents injuries by preventing accidental closing. This kind hinge is perfect for use in tough, medical, or hazardous environments. The hinges can be configured to have different degrees or free play, and can be designed to function at a variety of angles.
