We believe with a Rock Door you are creating the right impression and improving your mood each and every time you arrive home, in the knowledge you are ahead of the public and a few steps ahead of the thieves. They are available in 10 colours as well as white

Ever since Rock Door created their composite door it has been the benchmark and imitated by others, as it’s style and security speaks volumes in its class. To date no door has matched the quality available of each component that goes into making one of their doors and is why they are still way ahead of their nearest rivals.
Previously with such quality came a heavy price. Now Southport Doors & Double Glazing can bring you this range at a price that fits any budget.
Every door is one of it's kind and made to measure, with low maintenance and they wipe clean with a damp cloth.
All handles are spring loaded for ease of locking, for the less mobile/weaker arm customers. Available with wheelchair friendly thresholds. And disability handles/rails can be installed with the doors. We can source a range of handles. We can supply or install across the Northwest including Southport, Formby, Ormskirk, Tarleton, Halsall, Maghull and St Helens.
A COMPOSITE DOOR is best described as the nearest thing to real wood, without the hassle of sanding, painting, rot treatment and so on. These doors work in exactly the same way as a timber door with an exact likeness for wood effect finish , and with up to 6 times the insulation. A traditional uPVC door is glazed with a panel and beaded in a similar way to a window ,the problem with this is that they are open to warping and twisting over time . Composite doors have a bespoke designed slab which is hung the same way as a timber door therefore not allowing any movement under any strain or heat. As a whole composite doors give you the complete ease and benefits of a uPVC door but with the traditional solid look of a timber door and high security that is unmatched.
All Rock Door composite doors come with a 10 year guarantee from Rock Door |
