How many keys do I get with a Rockdoor?

You get 3 purple branded Rockdoor keys as standard, they are easy enough to get cut at your local key cutting store, however if you require the purple branded Rockdoor keys, please speak to your supplier.

What is the thickness of a Rockdoor sash?

The Rockdoor door sash is 50mm thick.

Can I have laminated glass in my Rockdoor?

Yes, Rockdoor offer laminated glass in their doors, however you typically need clear glass internally or internally to have laminated glass.

Does Rockdoor manufacturer the Ultimate, Select & Elite range still?

No. Rockdoor ceased production of the Elite & Select range in August 2018, and the Ultimate range is just branded as Rockdoor now.

Security Features

What makes Rockdoors more secure than other composite doors?

Rockdoors have a 50mm thick sash, and are reinforced with thick aluminium that is mitred into the corners of the door perimeter where the hinges and locking mechanisms are fixed into giving incredible strength. A one-piece steel keep running the full length of the outerframe provides a secure place for the steel hooks to engage into.

What is the role of aluminum reinforcing in the door's security?

After thorough research and development, Rockdoor chose an aluminium box section which is 10mm thick at the back wall to reinforce their doors. One of the major drivers for this decision amongst others was to minimise the warping of a Rockdoor, and all Rockdoor manufactured now come with a 3mm bow guarantee.

What locking mechanisms do Rockdoors use?

Rockdoor use a multi-point locking mechanism manufactured by Winkhaus. The lock comes standard with 2-hooks (one top and one bottom) along with a centre latch and deadbolt. A 4-hook locking mechanism is an option for your Rockdoor.

How do Rockdoors protect against common break-in methods?

Using a TS007 3* Sold Secure Diamond cylinder made by ATK, Rockdoors prevent any type of tampering with the locking cylinder, prevent things like snapping, bumping drilling and picking.

A multi-point locking mechanism that is very robust along with S-Glaze technology ensures the glass cannot be tampered with and forced entry is virtually impossible.

What is S-Glaze Technology?

S-Glaze technology is Rockdoors alternative to the traditional way of installing glass units in composite doors and doing without cassettes. S-Glaze encapsulates the glass into the door, sealing it in with high density polyurethane foam, ensuring it is 100% draught proof. Other benefits are no unsightly cassettes are needed, water ingress is not an issue as well as being more energy efficient and secure.

Are there any smart security features available, like smart locks or doorbell cameras?

Rockdoor do not offer any smart security features such as fingerprint scanner, camera's or smart locks. However the Yale Conexis L1 lock can be retrofitted after installation although we do not recommend it.

How does the steel mesh option add to the door’s security?

The steel mesh option for your Rockdoor works much the same way steel is used to reinforce steel. The steel mesh reinforces the core of the Rockdoor and greatly reduces cut-through, making it almost impossible.

What are some customer testimonials or case studies that demonstrate the door's security features?

Rockdoor made headlines back in 2004 for the article published 'door that beat the bobbies'. The local police were breaking into a house in Lancashire when they came across a Rockdoor, unknowingly of its superior strength, they failed to get past it with their battering rams and had to find another way into the property.

Energy Efficiency

What are the energy efficiency ratings for Rockdoors?

Rockdoor can reach energy ratings of an A, however this will depend on the glass design chosen for your Rockdoor, typically a clear backing glass offers marginally better energy ratings. These can drop down to a D rating on some configurations which sounds bad but is still very good.

How do they contribute to reduced energy bills?

With a Rockdoor, they are engineered to keep the outside out, and the inside in, ensure your house stays warm in the winter through minimal heat loss, and stays cool in summer by keeping the heat out. Their S-Glaze, polyurethane core and 50mm door sash all combine to achieve this.

Installation & Maintenance

How long does it take to install a Rockdoor?

Installing a Rockdoor properly is very important and cannot be rushed. There is no fixed answer for this as there are so many variables, however, it typically takes around 4 to 7 hours to install a Rockdoor.

Can I install a Rockdoor myself?

You can, however we strongly recommend to get an experienced fitter who not only has years worth of experience fitting composite doors, but also has fitted a few hundred Rockdoors so they know exactly how to set them up and adjust them for perfect operation.

We recommend using nothing more than warm soapy water to clean your Rockdoor sash, frame, cill and threshold.

Do I need to lubricate the hinges and locks? If so, how often?

Typically this is not required, however should you feel the need to, we recommend Lithium 3-in-1 white grease to spray onto the hooks. Do not spray anything into the cylinder.

Can I repaint or refinish my Rockdoor, and if so, how?

We do not recommend you to paint your Rockdoor sash or frame. This will void your guarantee.
