20 Questions You Should Always Have To Ask About Double Glazing Door Lock Before You Decide To Purchase It Double Glazing Door Locks

Many homeowners choose double glazed doors and windows to increase insulation as well as energy efficiency and noise reduction. They are also an effective deterrent for burglars.

To enhance the security of your double-glazed windows, ensure that they have been fitted with anti-jemmy hinges. These specialised hardware components make it difficult to get windows sashes.

Multi-point locking

Multipoint door locks can be one of the most effective security devices you can put in your workplace or at home. They are virtually impossible for anyone to pick or break, and are a great option to add to any security system. They can also improve your energy efficiency by reducing drafts around the doorframe and improving the seal.

Multi-point locking systems are composed of a deadbolt, a live bolt, and hook bolts located 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 across the length of the door. In commercial settings, they are called "full-width" systems because they protect the entire opening.

Multi-point locking is a feature on the majority of uPVC and certain timber doors. This type of lock offers an increased security level than regular locks and is often be specified as part of an approved by the police Secured by Design initiative for new construction homes.

When a multi-point lock made of uPVC door is shut the handle on the outside 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 the lock key. Always use a key when you lock your door. Using handles to lock the door can damage the latch or deadbolt.

If your uPVC lock isn't working 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 observing for gaps at the miter joints.

It is worth consulting your double glazing specialist if there is an opening and how to close it. They'll be able replace the lock on your behalf 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 in order to get it working again.

Espagnolette locks have become a standard locking mechanism for double-glazed uPVC windows. The shape of the flat strip that changes when you turn the handle is a great method to identify them. They work in tandem with secure multi-point locks placed around the frame to lock and release your windows.

They are available in a variety of styles, both contemporary and period, and come 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 however, espagnolette locks have also been criticized for delivering inadequate security for French doors.

These types of doors are typically used as the main entrance to your home. They must be secured to minimise the risk of intrusion by a stranger.

The espagnolette lock is not a bolt, but an uni-piece mechanism that can be fitted externally on the edge of French doors or internally to a casement frame. The mechanism is operated via a handle and comprises of a rod that has hooks at the head and at the sill that fit into sockets in the window frame. When the window's handle is operated the rod is moved upwards and downwards. The hooks then lock into their receivers.

They are a great option for those who want to increase the security of their French doors without compromising the aesthetic of the door or the overall look of the room. These handles can be used in a variety of designs and can be master-keyed for added peace of mind.

Similar to cockspur handles espagnolette handle designs come in both inline and cranked models to match the orientation of your window. Inline versions move 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 difficult to break. It is also more secure than regular glass since it is a single piece of safety glass, rather than shattering into loose sharp shreds. This makes it perfect for residential and commercial properties.

Lamination is a process which is the process of combining two pieces of flat glass with a plastic interlayer in between. The whole piece is then heated and placed under pressure to make it stronger enough for the construction of a door or window. The laminated glass that results is five times stronger and a hundred times stiffer than the glass that is tempered. It is also able to endure more severe impacts, and resist weathering.

double glazed window lock repairs of glass is perfect for buildings that need to perform well, such as enhanced security (impact-resistant glass) and UV protection or noise reduction. Laminated glazing can be used with a high-performance coating in order to enhance both thermal insulation and solar control. It comes in a range of options to suit your budget and project.

Laminated glass is more secure to use than tempered glass since 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 great option for glass that won't open or close like cellar windows.

It can also be used to reduce the sound that travels through high-rise buildings. The Saflex PVB interlayer in the laminated glass also helps to suffocate some of the sun's damaging UV rays, preventing discolouration of furnishings and fabrics.


Although laminated glass is more expensive than tempered, it has many benefits that will help you save money over time. It's also more durable and resistant to abrasions and scratches, and can be made according to your specific requirements. In addition, it's less susceptible to heat damage, and is a great choice for high-rises and coastal areas. Certain building codes require that exterior doors and some interior windows are made from laminated glasses.

Friction hinges

Friction hinges are designed to support and hold the positions of doors or flaps, panels and windows. They can also impede other hinges' motion and prevent slamming hard and unintentional closing and opening. They are available in various sizes and shapes. They can be fitted with different torque levels which are the forces that determine how long the hinges will stay open or closed.

Aluminum is an excellent material for friction hinges due to its strength, durability, resistance to corrosion, and high strength-toweight ratio. It is also lightweight and easy to handle. It can also be crafted into a variety of finishes, and is simple to install and repair. Another popular material for friction hinges is brass. Brass is an alloy composed of zinc and copper. It is a natural corrosion resistance. It is also more durable and stronger durable than steel, however it is more expensive.

The hinges made of friction used in uPVC double glazing door systems can be tailored to the specific requirements of the particular application. These modifications 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 environment where the hinge will be utilized. These variables can affect the dynamic torque of the hinge, and it is essential to monitor this metric for critical applications.

There are different types of friction hinges, including detent and one-way. Detent friction hinges do not have torque in the opposite direction. Other variations include curl, disc, and pipe friction. Each type of hinge is distinct and has its own set of characteristics, making it more or less useful for specific applications.

Friction hinges are also referred to as hinges that stop free because they permit doors or lids to remain at an angle even after the force has been removed. This helps prevent injuries through accidental closing. This kind hinge is ideal for use in medical, tough or dangerous locations. The hinges can be configured to allow different levels of free play and are able to function in a variety of angles.
