Structurally, one of the most important parts of a door is the jamb (a.k.a frame). A door is only as strong as its weakest link, and all too often the weakest link is the jamb.
This is especially true for security doors. You can install the best FE/BR (forced entry/bullet resistant) door in the world but if your jamb is not up to the job, you’ll still be able to kick the door in.
Door jambs are an easily over-looked piece of the puzzle. The jambs for the Shield Fortress series and Embassy series doors are constructed from 14 gauge galvanized steel with a unique L-shaped profile that protects the locking bolts from attack. Each locking bolt is protected in a steel pocket that ensures that if someone attacks the locking bolts, they can only do so one at a time.
Multi-point locks are pretty self-explanatory: they bolt the door at multiple points. Typically, entry doors on a home will have a 1-inch deadbolt but this isn’t enough to keep a door secure against a basic attack such as being kicked in. Why?
The physics behind a multi-point lock are simple: it distributes the pressure of a brute force attack (such as a kick-in) across multiple locking points instead of being absorbed by a single point, like a 1-inch deadbolt. By dispersing the force across multiple locking points, a door can resist more impacts and more pressure.
There are many different multi-point locks on the market, and these locks should never be judged simply by the number of bolts they have because there are many different ways to attack a lock that does not involve pure brute force.
Multi-point locks are essential in any high-security door and at Shield we offer two types: the Mottura 85 series mechanical lock and the Fiam X1R motorized lock.
Physically, the two are very similar and have the same security rating under European standard EN 12209. So you don’t lose security by choosing one over the other. The big difference is that the Fiam motorized lock allows you to integrate a range of access control options such as keypads and biometrics and also to tie the door in with a home automation system.
These locks also allow us to have up to 20 locking points on Shield doors: 10 on the lock side, 1 each into the top of the jamb and the threshold, and 8 on the hinge side.
In the next post, we’ll look at the importance of a solid door jamb (a.k.a frame). Because a door is only as strong as its lock, and a lock is only as strong as the door jamb.
The majority of our clients call us because they share one big concern: keeping their families safe. Most aren’t motivated to install security doors to protect their fine art or jewelry collection – that’s all insured. But spouses and children aren’t replaceable.
We try to identify how and where our clients will get the greatest bang for their buck, and this is especially important when working on a limited budget. Assuming the budget only allows for one door, we usually recommend replacing the master bedroom door (for families without children) or a passageway door that leads to the bedrooms (for families with children). Then we train our clients to lock that door at night.
Installing a security door on a bedroom addresses the greatest number of security scenarios that can be achieved with a single door.
And of course, by matching the other doors in your home you can ensure that your high security door does not stand out or draw any special attention. Because the secret to good security…is to keep it a secret.
There are all sorts of security doors on the market. Most people have heard of bullet proof (a.k.a ballistic) doors, but lesser known types of security doors include fire doors, forced entry resistant doors, blast resistant doors, and others. They are all designed to keep you safe from something. The problem is that over reliance on one type of security door leaves you vulnerable to asymmetric threats.
For example: it’s great to have an expensive ballistic door, but what’s the point if it can be pried open with a crowbar in 30 seconds? And what’s the point of a sophisticated forced entry resistant door if it has a standard cylinder that can be bumped or picked in 30 seconds?
You want a door that will ensure you and your family are safe no matter what type of threat comes knocking. When doing your research, consider the following requirements:
Want to know the secret to good security? Keeping it a secret. A criminal will have a much harder time breaking in when they don't know what they're up against. And because all Shield doors are custom-made, they can be designed to look like anything and therefore not to attract any special attention. All of these factors are why a custom-made high security door from Shield is the gold standard in security.
