Rockdoor

Strong, Secure Rockdoor

With a wide choice of designs, Rockdoor offers styles to complement every type of property, including traditional and contemporary homes.

Rockdoors are built using a fully engineered composite system, reinforced with aluminium and uPVC profiles and filled with high-density polyurethane foam. This advanced construction creates a front door that is up to 35% stronger than a standard GRP composite door.

For even greater protection, each door frame is reinforced with aluminium as standard. There is also the option to upgrade with a steel security mesh, making the door up to four times stronger and highly resistant to attempted forced entry.

Stylish composite doors

There are many designs to choose from in a choice of 14 popular colours, each with a texture to give the appearance of a wooden door.

If you would like to maximise the amount of natural light entering your home through your front door, there is an extensive selection of glazing options available, including clear, sandblasted, reeded and decorative designs, all of which have toughened safety glass. To complete your stylish design, we also offer a wide range of door handles, door knockers and letterboxes in a choice of colour finishes including polished chrome, graphite, midnight black and polished gold.

Each door we install is made to measure, ensuring a flawless fit in your property. Whether you need a front door, back door, stable door, or are considering replacing a single door and sidelight with elegant double doors for a wider opening, we can help you design the perfect solution for your home.

A Rockdoor does not just protect your home, it adds value, efficiency, and peace of mind.

Solidor

Composite door designs and colours

Within our Solidor composite door range, you will find an extensive selection of front door styles, each available in a spectrum of colours to complement your property.

Many designs can be enhanced with clear, satin, decorative, or bespoke artistic glazing. These options add character and individuality to your entrance, while maintaining privacy and allowing natural light to flow into your home.

For cottages and farmhouse-style properties, our vertical panel designs offer timeless rustic appeal combined with the durability and security you expect from a Solidor composite door. This style known as the Flint Collection, is available as a solid door or with a choice of double-glazed designs. It is also a popular option for stable doors, providing traditional charm with modern performance benefits.

For additional safety and security, we fit a Winkhaus AV4 Autolock to our Solidor composite doors, so that when you pull the door closed, it locks automatically.

Arched composite doors

Many of our Solidor composite door designs are available with a bespoke arched frame and optional glazed sidelights, creating a striking focal point for your home’s entrance. Arched doors are a popular choice for replacing original period features in traditional properties, while increasingly being recommended in new-build and refurbishment projects where clean, minimalist architecture allows the front door to stand out as a defining design feature.

Each arched composite door is manufactured to the same standards as the rest of our range, incorporating advanced multi-point locking systems for enhanced security and high-performance insulation for improved energy efficiency and comfort.

Features of Solidor Composite Doors:

  • 44mm Solid timber core
  • Side panels or top lights can include house name or number
  • Decorative glass designs
  • Automatic AV4 Autolock
  • With NUKI Smart lock option
  • Modern, traditional and heritage door hardware to choose from
  • Modern Chamfered or decorative Sculptured outer frame
  • Low threshold option suitable for wheelchair access
  • Choose from Single doors, double doors, stable doors, and arched doors

Hallmark

Thermally efficient composite doors

Hallmark composite doors are engineered for outstanding energy efficiency, helping to keep your home warm and your energy bills lower. Our solid doors without glass achieve U-values as low as 0.8 W/m²K. While our glazed doors achieve U-values of 1.4 W/m²K, ensuring all doors meet current building regulation requirements.

With 135 traditional or modern door designs to choose from, and a huge collection of colour options and glass designs, you have the freedom to design a bespoke Hallmark composite door to fit perfectly in your home.

Secure Front Door

Our Hallmark front doors are fitted with a German-engineered multi-point locking system, designed to provide exceptional security. These doors can meet both PAS 24 standards and the Secured by Design specification for added peace of mind.

We offer a selection of lever handles or pull bar handles in a variety of finishes.

Hallmark composite doors fitted with a pull bar handle are paired with an Autolock system, which automatically locks the door as soon as it closes. With this system, a key is required to unlock and enter the door from the outside. If you would prefer to move in and out of your home without needing a key to unlock the door each time, such as when you are gardening or you are at home and do not need the door to be fully locked for a few hours, we can fit a convenient day-switch feature which you simply turn on and off when needed.

With our lever handles, the locking mechanism is operated by lifting the handle to engage the hooks, then turning the key to fully secure the door. For additional convenience, you can also choose to include an internal thumb turn which is available in black or silver.

Features:

  • 44mm thick GRP door sash
  • Wide range of door furniture to choose from
  • Decorative door knockers, with designs including a Dragonfly, Lions Head, and a Bumblebee.
  • German engineered multi-point locking system
  • PAS24 security and Secured By Design options
  • Steel reinforced outer frame
