How Double-Glazed Doors are Made

It is important to first understand how double-glazed doors are made. Brackenwood’s robust, double glazing is made by sandwiching two panes of glass together with a layer of Argon gas in between. The space between the two panes of glass creates an insulating barrier that helps to keep your home warm in the winter and cool in the summer.

 The glass used in double-glazed doors is typically toughened or reinforced and is difficult to break. Toughened glass is heated to a high temperature and then rapidly cooled, which makes it stronger than regular glass. GRP glass (Glass Reinforced Plastic) is made by sandwiching a layer of plastic between two sheets of glass, which makes it more difficult to break and also helps to reduce the level of external noise. It also prevents noise from filtering outside. This ultimately makes your home a very private and secure place to be. Brackenwood’s double-glazed doors are  made from uPVC, solid timber core composite, or aluminium.

  • uPVC front doors are the most popular choice. They are low maintenance, durable, and incredibly energy efficient.
  • Solid timber core composite front entrance doors are popular. They offer a traditional look and feel. However, they do require more maintenance than uPVC frames.
  • Brackenwood’s aluminium front and rear door collection is a perfect blend of material, style, security, and precision engineering. They are also reassuringly secure with options from standard key locking to extremely high security bio-metric access systems coupled to remote monitoring and access systems.

Overall, the combination of toughened or GRP glass and sturdy frames makes Brackenwood’s double-glazed doors a secure option for your home. However, there are other factors that can affect the security of double-glazed doors, which will be discussed, next.

Factors that Affect Double-Glazed Door Security

Whilst double-glazed doors are generally considered to be secure, there are several factors that can affect their security. The quality of the materials used is one of the most important factors. Low-quality materials can make the door more vulnerable to break-ins. For example, if the glass used in the door is thin or weak, it can be easily shattered. This could allow intruders to gain easy access to the property. Similarly, if the frame of the door is made from low-quality materials, it can be easily forced open. Unfortunately, there are doors out there in the market place, that seem very reasonably-priced. However, they do not conform to Brackenwood’s high-quality standards.

The strength of the locking mechanism is another important factor that affects the security of double-glazed doors. A weak or poorly designed lock can be easily bypassed by intruders. It is important to choose a door with a high-quality mechanism designed to resist forced entry. At Brackenwood, we have just that. Our multi-point locking systems ensure that your front doors are locked tight.

Finally, the installation process can also affect the security of double-glazed doors. If the installation is not done correctly, it may not fit properly in the frame. leaving gaps that can be exploited by intruders. It is important to choose a reputable installer, like Brackenwood, who has experience installing double-glazed doors and is a registered FENSA installer.

Whilst double-glazed doors are generally considered to be secure, it is important  to consider the quality of the material used and the strength of the locking mechanisms. By choosing a high-quality door and having it installed by a reputable installer, you can ensure that your home is well-protected against intruders.
