The ideal solution for bi-fold doors in glazed extensions. The bolstered eaves ensure you can easily incorporate a bi-folding door without affecting the bi-fold door’s operating mechanisms on regular projects. The Quantal bi-fold eaves eliminates the need for unsightly and costly steel structures to support door openings. The Quantal system provides a truly engineered solution without affecting the internal or external aesthetic.

Quantal’s bi-fold eaves can give you up to 4.3m openings using polycarbonate as your roof glazing material, or up to 4.0m using a sealed unit. This will provide an opening to fit typically a 4 or 5 panel bi-folding door, giving the homeowner lavish uninterrupted views.

* Further options include the insertion of rolled steels to further increase unsupported spans.


The optional features of Quantal’s unique, authentic period style aluminium roof with traditional solid cast cresting and finial are ideally suited for creating a truly stunning coloured glazed roof.

Coloured roofs are particularly suitable for enhancing the heritage feel of distinguished period properties. All our aluminium and internal cladding components can be coloured in any RAL or BS shade to allow customers an infinite choice across the whole range of conservatory designs.

Using our purpose built in house paint shop we ‘spray and bake on’ at 60 degrees, using the same high-grade acrylic formulation and technology employed on modern car bodywork.

The result is a totally colourfast and durable finish, fully guaranteed.

The internal pelmet helps you create a glazed extension with a more ‘room-like’ feel. It combines all the benefits of a glazed extension in terms of light, and then fuses this with the solidity and feel of an extension. This effect can be played up or down depending on whether glazed walls or masonry walls are specified. All of this can be achieved at a price point not dissimilar to that of a standard conservatory.


A decorative Cornice adds shape and style to any roofline, concealing gutters and rafter ends. There are 4 Cornice styles to choose from. The curved Cornice includes a die cast 135° and 90° corner cover as well as straight jointers, which will help fitters achieve a consistent fit and finish at critical junctions. 1, 2 & 3 tier Cornice ONLY 90° corners and straight joiners available.
