Quantal Roof


Choose a Quantal aluminium conservatory if you want something distinctive. Made from aluminium, it’s even stronger than a uPVC or timber system and can be customised to suit your requirements.

The Quantal aluminium conservatory roof has been engineered to deliver superb performance across all vital criteria. This system looks unique and has been designed with planning regulations in mind.



So 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 aluminium conservatory, we build it to specification using U-Design software – a unique program that uses each customer’s postcode to factor in snow and wind loading.

To streamline the installation process for your aluminium conservatory roof – and keep disruption within your home to a minimum – we pre-fabricate the Quantal roof off-site as far as possible.

Quantal is an ideal choice for aluminium 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 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.

Quantal conservatory roof interior



Quantal can incorporate an internal pelmet, an inner 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.


The strong, slender and lightweight nature of aluminium lends itself to grander glass extensions, orangeries and conservatories where design is at the heart of the planning process.

The Quantal aluminium conservatory is designed for large spans and footprints and, with an almost endless range of 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.


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 five 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 comfortable.

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.
