Ultraframe recommends several types of support for box gutters including brick piers. Fitting a conservatory box gutter without adequate support will lead to structural failure. Please take care to ensure the customers are aware of the required amount and style before the roof is signed off. For details on our structural gallows please contact Ultraframe's Technical Department.
Box Gutter Straps
165mm and 265mm box gutter straps.
These are supplied loose and MUST BE FITTED – they are a structural
requirement of the roof. The straps must be installed within 75mm of
glazing bar centres ( when measured from centre of the strap to the
centre of the bar). To install these straps, simply `nip up` as shown.
Special box gutters
Box Gutter Hanging Brackets
165mm box gutters
If these have been specified by your company at the time of order they
are supplied loose and must be fitted. They need to be installed at
maximum centres of 4m on polycarbonate roofs and 3m on glass roofs.
Drill through the head of the hanger into the centre of the masonry,
avoiding the mortar joint if possible. Use a masonry anchor suitable for
the substrate. Lead flashing should be dressed down over the hanger,
and snipped around the sloped leg.
To attach it to the box gutter, simply `nip up` as shown.
265mm box gutters
Hanger not available.
Gallows brackets
These are available for 165/265 box gutters.
To install, notch out the insulation to ensure metal to metal contact
between the extruded box gutter and gallows bracket. Offer up the
gallows bracket and mark it ready to drill – always try to line up with the
centre of a brick rather than a mortar joint. Drill the gallows bracket ( the
positions should be similar to the ones shown). Three masonry anchors
should be used that are appropriate to the substrate.
Finally, notch out the undercladding, offer it into position and clip in.
