Architectural Portal Structures

At Ultraframe our technical teams have the ability to aid you in the development of larger scale conservatory roofs or portal conservatories as they are known. These conservatories are built using an aluminium supporting skeleton that sits inside the conservatory. Due to the  more technical aspects of larger scale conservatory projects, Ultraframe’s expertise is a vital aid to the completion of a successful project . Ultraframe are able to provide project management from concept right the way through to project completion.

Conservatories are generally able to reach approximately six metres before a sub-structure support is required although use tie bars are fitted in the roof. If a supporting sub-structure is required it will tend to be made from high- grade aluminium, steel or timber and needs to be fixed to the ground. The large conservatories will need to ensure that supporting sub-structure that has been approved by a structural engineer.

Large or portal conservatories tend to need planning permission and usually building-regulation approval too. Depending upon location and wind/snow loads.

As a result of the widespans support that portal frames provide, it makes them ideal for hotels, office canteens, swimming pool covers and at schools


Restaurant and Hotels

Ultraframe have provided solutions to a variety of our customers including large portal structures for commercial projects including hotels and golf clubs. Providing them with the ability to allow their guests to enjoy the beautiful scenery that the hotel is situated in.

Schools and Colleges

Many Schools have used our Portal Systems to create added spaces for their students, including a recent project on a school gym, and due to off site manufacturing techniques portals are put up safely and efficiently meaning minimum disturbance is caused to pupils and staff.


Swimming Pools

The Ultraframe's pool enclosure system is manufactured from high strength/low weight aluminium profiles that are powder coated to give a corrosion resistant finish. All window framing and decorative roofing components are manufactured in aluminium for a well insulated, low maintenance, high thermal performance finish. Glazing options include high performance double glazed units. 

Bespoke Projects

If a more bespoke portal frame is required, working with our technical team this may be achieved. The team can advise on the best manner in which to meet the criteria for your project taking in to account strength and load capabilities for example.
