What makes Rockdoors secure and thermal efficient?

There are many advanced technologies that go into Rockdoor to make it unrivalled when it comes to keeping cold air and burglars out. You can read more about how and why these composite doors are so strong here: What makes Rockdoors so secure?

What is Laminated Glass and do I need it?

Laminated Glass is special type of glass that holds itself together when broken, thus making it safer and more secure. During manufacturing, there is a very strong adhesive layer (called PVB) that is sandwiched between two layers of glass. When the glass is broken, the PVB layer between the two pieces of glass holds it all together and makes it very hard for someone to get through it, the glass will remain stuck together and can still keep wind and rain out until it can be replaced. Due to its strength it stops the glass from breaking it large fragments and is safer overall. Another benefit is that in some cases, the laminated glass can be better for sound proofing due to the PVB layer. Standard toughened glass is strong enough and takes some force to break, in most cases this is just as good, but for those who want to maximise security, laminated glass can be a cheap way to improve it.

What happens if the Glass in my Rockdoor needs replacing?

Some people are a little bit put off by the fact that if the glass fails inside a Rockdoor, you have to change the whole sash (remove letterbox, handle, locks etc from the old sash and put them on the new sash), you can't just replace the glass, the truth is, we have never ever been called out to anyone who has had faulty glass in their Rockdoor, due to the glass being completely sealed inside the Rockdoor from air and moisture, this actually helps prevent the glass from failing, and to smash the glass in a Rockdoor in itself is a very difficult thing to do.

Do I need 4 Hooks, Steel Mesh and Laminated Glass?

I always tell people that 2 hooks, standard core and standard toughened glass is plenty for security. However, if you lived in a fairly remote area where attackers could spend a longer period of time trying to break through your door than they would do on say an estate with lots of houses etc, then it may be worth it. I’ve witnessed attackers trying to get through a Rockdoor with sledgehammers that had 2 hooks, a standard core and toughened glass, they failed with the door virtually intact, but they made such a noise, they had to run after several hits, so no, these extra security options are not required and you will still have a very secure door, if it gives you that added peace of mind or you live in a remote area then it can be worth it.

Is the Aluminium/Low threshold less thermal efficient than a Slim PVC?

Yes, in a laboratory. In real world conditions inside a house, you are not going to notice a different at all due to the extremely small difference there is between an aluminium threshold and a PVC threshold, so don’t let this small difference change your mind!

Can I have a Bar Handle on just the outside?

No, if you have a har handle, it is External and Internal. Due to the way a bar handle and locking mechanisms work, the door is CNC’d for a bar handle only, so a bar handle on the outside and a lever/lever handle on the inside is not possible.

How does A Rockdoor with the Bar Handle work?

A Rockdoor with a bar handle is operated just with the keys. From the outside once the door is shut, you turn the key clockwise twice and take the key out, this brings the hooks out and locks the door secure. To get back inside, you insert the key and rotate anti-clockwise twice to dis-engage the hooks, you then pull the Rockdoor towards you slightly with the bar handle to release the pressure off the latch (depending on how tight the latch is) and turn the key anti-clockwise (from 12 o clock to about 10 o clock) to bring the latch in so the Rockdoor opens. It is exactly the same for inside except you can put your weight on the bar handle to release the pressure on the latch depending on how tight the latch is set.

Is 4 hooks available with a Bar Handle?

No, due to using the key to operate the hooks when you have a bar handle, 4 hooks cannot be selected as an upgrade with a bar handle. You would need a proper Lever/Lever handle or something of the type.
