Fitting and Usage
Glazing and ALUKAP-SS Bar Length
ALUKAP-SS bars should be ordered to the same length as the roof glazing material, or the next available size.
We recommend that glazing material stops 15mm short from host wall at the top (providing expansion gap) and oversails the Eaves Capping at bottom by 30mm (providing drip over the gutter).
Bar Length = Length along Pitch +/- Expansion Adjustment + Gutter Overhang
Example Glazing/Bar Length Adjustments
| Roof Pitch | Length along Pitch | Expansion Adjustment | Gutter Overhang | Bar/Glazing Length |
|---|---|---|---|---|
| 5° | 2,200mm | - 6mm | + 30mm | 2,224mm |
| 10° | 2,200mm | n/a | 2,230mm | |
| 15° | 2,200mm | + 8mm | 2,238mm | |
| 22° | 2,200mm | + 15mm | 2,245mm |
Glazing Width and ALUKAP-SS Bar Quantity
Glazing Deductions
The ALUKAP-SS Top Capping is secured with screw fixings going into the Main Bar upstand. So glazing width deduction must be made to allow for them and expansion.
Glazing width should be reduced by 15mm from centre-to-centre measurement of neighbouring bars.
If centre of one bar to centre of next is 980mm, then the glazing width should be 965mm (980mm - 15mm). This simple rule applies to the Main, Gable and Wall bars.
Glazing Width = Centres Space - 15mm
Calculating Quantity of Bars Required
The quantity of bars to cover the roof width is governed by factors including geographic location, roof pitch, projection from host wall and glazing material. Each factor affects the recommended glazing width, which affects the number of bars required. Generally speaking, the shallower the pitch and the longer the projection, the narrower the glazing width should be.
