Ultraframe Roofing System.
Don't take chances make sure your conservatory has the tried and tested roofing system
with independent certification to prove it. Ultrafame has managed to secure the following certification:

Complete Structural Integrity.
   
The government test agency, the British Board of
Agreement (BBA) stated 'the conservatory roofs
will have a life of at least 25 years.' When you
sit in your conservatory, no one can imagine
what the weather will impose on your roof. Over
an average 25 years it would include:
  • 15,300mm of rainfall.
  • 450 days of snow falling.
  • 57 days of hail the size of peas.
  • 9125 days with the temperatures in the range
    of -15 degrees C in the winter
    to +35 degrees C in the summer.
  • 300 visits by window cleaners, house painters
    and aerial riggers
Wind Loading - care is needed in design
to prevent water ingress under the
positive and negative pressures created
by wind movement.

So you can see why it needs to be tough. When the wind blows on to the face of a conservatory there is a
consequent build up of pressure on the back face. As it is deflected over the roof and around the sides; the
reduction in pressure creates suction in these areas. Careful design is needed to ensure the integrity of
the whole structure and to prevent water ingress.
In winds of 110 mph and heavy rainfall, equivalent to the worst UK conditions, the BBA gave our roofing
system a 25 year life expectancy. Typically the roof is designed in line with British Standards to support an
imposed load of 75 kilogram’s per square metre - equivalent to 600mm or 24 inches of snow in one fall
or the equivalent of one and a half bags of cement per metre squared.
   
     
   
   
   
     

See picture to the left: The roofing system has been loaded
with the equivalent of 1.5 bags of cement per metre square,
1.5 times greater than required by building regulations.
The combination of these factors means that the roof has to
be strong, durable and attractive.
Each roof is carefully specified from a portfolio of 3500
components, ensuring maximum structural performance.
The roof system comprises structural aluminium profiles
which have bolted joints rather than poorer quality screws
which are often employed. Each structural aluminium profile
is then capped and clad with pvc-u; these items are known
as thermal claddings and they minimise the formation
of condensation.
