Stylish Aluminium Roofs for a Distinctive Look 

Choose a Quantal aluminium roof for something distinctive. Aluminium is stronger than uPVC or timber and is ideal when you want  a product that will be customised to suit your design requirements and engineered to deliver superb performance across a range of vital criteria. This is a roofing system that looks unique and has been designed with planning regulations in mind.

So that our customers can buy from us with peace of mind, we asked the British Board of Agrement (BBA) – a lead body that approves and certifies manufacturer’s products – to assess and approve our system.

To guarantee the longevity of your Quantal aluminium roof, we build it to specification using U-Design software – a program that uses each customer’s postcode to factor in snow and wind loading. To streamline the installation process and minimise disruption to our customers, we pre-fabricate the Quantal roof off-site.

Modern Technology, Creating Grand Designs

Quantal is an ideal choice for conservatories, its slender frames offering a more elegant look than other materials such as uPVC and wood. The versatile construction system allows virtually endless design options, while the wide range of finishes and on-trend colours mean your finished conservatory can perfectly complement or contrast with the rest of your home.

Choose Quantal and benefit from all of this and more:

  • A choice of glazing bars. These can work with wide-spanning structures too, to help you build your structure as planned and prevent you from paying more than you need to.
  • Superb thermal performance and condensation elimination. This is delivered in part by the externally sleeved aluminium, chambered combi eaves, box gutter and foam insulation.
  • Innovative Speedlock attachment. This performs two crucial functions – it perfectly aligns the glazing and prevents the ingress of water via a dedicated weather seal feature.
  • A wide variety of eave options. The Quantal roof can be adjusted to 2.5°. It can be used with lean-tos, and the eaves can be strengthened to cope with wide-openings and Gable designs.
  • Limitless Choice of Colours. The range of choice is almost limitless, and the results last – thanks to the acrylic formula used in our paint and the technological methods we use.
  • Create Beautiful Sightlines with a Cornice. Add a decorative cornice into the design mix to create clean sightlines. Made from aluminium, the fine detailing will add a touch of style and presence while hiding your guttering from view.

Three Benefits of the Quantal Aluminium Roof System

Add an Insulated Pelmet

Quantal can incorporate an internal pelmet, an internal frame system that’s plastered to create a ceiling that extends around the perimeter - instantly creating a sense of permanence and adding a ‘real room’ feel to the design.

The internal projection of the internal pelmet can be adjusted to between 300-1200mm, depending on your requirements. It can be used with side frames and is also compatible with our super-insulated columns and brick piers.

Limitless design choices

The strong, slender and lightwieght nature of this Aluminium lends itself to grander glass extensions, orangeries and conservatories where design is placed at the heart of the planning process. Quantal is designed for large spans and footprints and with endless design options you can create stunning period or contemporary builds. 

A Quantal conservatory, orangery or glazed extension can be painted in virtually any colour to either match existing window frames or deliver a stunning contrast to the rest of the house.

Add Super-Insulated Columns

Complete your Quantal build by adding super-insulated columns. Compared to brick piers of the same size, they will deliver thermal performance levels up to 5 times higher – so you’ll be able to enjoy your room year-round. Plastered on the inside they add solidity to any conservatory making it cosy and confortable.

Super-insulated columns can be fitted in a flat or fluted format and two sizes – large or small. The former of these is best placed at corners, while the latter works best as part of a sequence spread across the remaining space.
