Products : Conservatories : Roof Construction
The specialist construction and installation of a conservatory roof is a vital element of this home improvement project. In addition to looking good, it must withstand the worst extremes of the British weather, year after year.
At Nolan uPVC, we use high gloss, polyester powder coated aluminium frames as opposed to standard uPVC frames which is a system favoured by other companies. The structural integrity of our system has been shown to meet the very latest and most stringent British Standards. It is one of only a few systems in the UK to have been awarded British Board of Agrement (BBA) certification, following analysis of product strength and weather tightness, including simulated wind and snow loading as well a sunlight ageing tests.
Our roof system combines authentic period aesthetics with optimum long-term performance. The following table of comparisons shows why.

Good Looks
Low maintenance 60 micron polyester powder coating - as used on most modern shops and offices - ensures high resistance to grime.
Early hoses clean - back to original pristine sheen.
One single, visually consistent colour to the outside roof |
Good Looks
Plastic finishes can become soiled more easily.
Due to the difficulty of access it is harder to restore a PVC-U roof to a satisfactory finish.
It is not uncommon or different shades to be noticeable across the roof structure. |
Strength
Nolan uPVC combine the strength of aluminium with a tough, high gloss, polyester coating, bonded to the exposed surfaces.
Aluminium beads enable significant pressure to be put on the glazing panels to prevent them shifting after instillation.
Box section aluminium eaves beam allows Nolan uPVC to build larger roofs than most of its competitors without the need for tie bars. |
Strength
Generally capped with plastic.
Rely on Knock-on plastic top caps to exert pressure.
If no box section is used, intrusive tie bar strengtheners are required on much smaller conservatories. |
Durability
Low thermal expansion of aluminium gives excellent stability. Particularly relevant with dark external finishes.
High gloss precision metal castings, based on an authentic original Victoria design, are used for the decorative crestings and finial. |
Durability
Plastic roofs are more prone to thermal movement, putting more demands on the long term.
Most PVC-U roofs use moulded plastic items. |
