Top of the Tops
A conservatory is a conservatory-as opposed to any other kind of home extension- precisely because of the kind of roof on top. It must look good whilst withstanding the worst extremes of the British weather, year after year.
Unlike most conservatory roofs, Quantal uses aluminium externally, which has many advantages over PVC-U. This unique system gives you distinctively authentic, traditional, period aesthetics combined with optimum long-term performance.
This leaflet shows the main advantages of the Quantal system compared to PVC-U roof designs.
Quantal External Aluminium System
PVC-U Externally Capped Roofs
Strength
Quantal 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 installation.
Box section aluminium eaves beam allows Quantal to build larger roofs than most of its competitors without the need for tie bars.
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.
Good looks
Low maintenance 60-micron polyester powder coating-as used on most modern shops and offices-ensures high resistance to grime.
Easily hoses clean - back to original pristine sheen.
One single, visually consistent colour to the outside of roof.
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 for different shades to be noticeable across the roof structure.
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 Vctorian design, are used for the decorative crestings and finial.
Plastic roofs are more prone to thermal movement, putting more demands on the long term sealing of the roof.
Most PVC-U roofs use moulded plastic items.
