Roof Lantern Installation Guide

Ensure there is suitable support in the roof structure to support the roof. The up stand kerb should be finished to provide a flashing down on to the roof surface below. The roof opening should be designed to suit the lantern you have ordered, or the roof lantern should be made to measure.
The cill from the roof lantern should bedded on a layer of neutral cure silicone, which should be applied as a continuous bead around the base of the roof lantern. This will stop any leaks which might be caused by high winds on rainy days

Drill down through the cill with self tapping screws in to the beam below at 400mm centre's (approx) Ensure the screws are long enough to securely fix the cill into place

 

Hint:

Check the diagonal sizes are equal before fixing the cill into place to ensure it is square.

 

Stand the window frames on the cill then add the four corner posts screw into to corner posts and down into the cill below.

 

Hint:

Screw the corner posts first ensure the windows are in the correct place before fixing down into the cill below.

 

Add the ring beam screw up in to the beam from the windows below and fix the corner brackets in to place. Ensure the whole beam is securely fixed.

Hint:

Fix the four corner brackets first then check the beam is sitting on top of the frames squarely before fixing it to the frames.

 

On bigger roofs its some times easier to fix the all the roof bars on to the ring beam then lift the whole lot on to the windows for fixing.

 

There are two sets of brackets these will ensure the beam is fixed and held tightly it binds the four roof lantern outer frames together.
Add the straight beams and the ridge section to the ridge beam bolt it to the ridge and to the ring beam. 

 

Hint:

Bolt the tops of the bars to the ridge section then lift it on to the roof lantern line up the bottom of the bars with the lower bolts and tighten.

 

The ridge beam has a d ring which will fix to the hip bars as shown below.

Fix the hip bars on to the d ring and bolt into place

 

Hint:

Do not over tighten the top end of the hip bars

 

Fix the bottom of the hip bars as shown.

For security the window frames are supplied with an internal bead glazing system you can fit the glass at this stage or leave it until the end and then glaze it from the inside if access is possible.

 

Hint:

Tap the beads in to place with a white headed rubber hammer if required. Start with the largest section of glass as the bigger they are the easier they are.

 

Put the glass in to place ensuring a clear gap for expansion both sides of the glass.

 

 

 

Hint:

Also add the drip beads to to glass panels.

 

Put the glass in to place ensuring a clear gap for expansion both sides of the glass once you are happy with the position you need to remove the yellow backing to the glazing tape then drop the glass down on to the tape. .
Check the bottom edge is correct before removing the yellow tape. The glazing tape helps to reduce noise and draft so its important not to forget to remove the yellow top on the tape.

Once the roof lantern glass is in place and fixed with the glazing tape add the top caps to the glazing bars push them down firmly until they clip in to place.

 

Hint:

Make sure bottom edge of the top cap is lined up before fixing do not worry about the top as it will be covered buy the top ridge cap.

 

Screw up in to the glazing bars through the black section on the bar end cap. the black section of the clip also holds the glass to prevent it from slipping

After the cap is screwed in to place lift the lower section up to cover the end of the bar.

 

Repeat the above process until all the glass is in place.

 

The gutter brackets are a hidden fix system which will clip lock on to the eaves beam as shown.
After you have clipped the brackets in to place the guttering is levered on from the front as shown then push the back of the guttering up in to the gutter clip until it locks into place.
Once all the glass and glazing beads are in place with the end caps screwed on clip the ridge section on the add the cresting and finials to the top if required.
Add the lower caps to the internal side .
