FULLY ASSEMBLED PYRAMID LANTERN: INSTALLATION GUIDE
INTRODUCTION TO THE GUIDE
This guide covers the installation of a Pyramid roof
lantern, where you have opted to receive it fully
assembled.
PLEASE NOTE: For roof lanterns that feature blackout
blinds, there is a blackout blind wiring guide available
which we can provide, or is available to download in the
technical section on our website. This also outlines the
additional components that you will receive, such as the
remote control and power pack.
ON DELIVERY, YOU WILL RECEIVE;
• Your fully assembled Pyramid Roof Lantern
IN ADDITION, YOU WILL NEED;
• Silicone sealant (recommended Dow Corning
791) for fixing the upstand frame to the Timber
kerb
• Timber screws for fixing the upstand frame to the
timber kerb (Min. 50mm length)
• Drill with hss drill bit to pre-drill the aluminium
upstand before screw fixing to timber kerb
Please adhere to the relevant Health and Safety
guidelines when moving heavy objects and working at
height. The weights provided below are for your
guidance only.

STEP 1: STEP 2:
PREPARE THE ROOF MEMBRANE
We recommend that you apply your roof membrane after installing your roof lantern,
to avoid damaging or piercing it during the installation.
If you have added your roof membrane on top of your plywood deck already, please
ensure that you leave enough excess material around the timber kerb to flash the roof
lantern upstand. This can be folded back out of the way until your roof lantern is
installed.
You are now ready to install your roof lantern.
Roof membrane folded back out of the way, leaving the timber upstand
exposed for the installation of the roof lantern.

PREPARE THE TIMBER KERB
Before you begin the installation of your new roof lantern, you will have installed the
timber kerb. The size of the internal opening should reflect the exact size of the roof
lantern you have ordered. For example, the roof opening should measure exactly 1m x
1m for a unit that measures 1m x 1m.
Your timber kerb should measure 70mm in width, to match the width of the built-in
upstand frame. We recommend a minimum height of 25mm from roof level, but this
can be increased if required.
The upstand should be perfectly level and we also recommend that you check the
corners have a 90° angle, by measuring it diagonally from corner to corner before
installing the roof lantern.
Ensure all 4 corners are square
Measure diagonally from corner to corner both ways. If both dimensions match, your timber kerb should be square.

STEP 3:
APPLY SILICONE TO THE TOP SURFACE OF THE TIMBER KERB
Apply a thick bead of silicone all the way around the timber kerb about 20mm from the
internal edge. Only use a professional quality silicone adhesive sealant such as Dow
Corning 791.
Following this, place the lantern on to the timber kerb and ensure it sits flush both
externally and internally.
Now that your lantern is fixed to the timber kerb, you need to flash it in,
which acts as the final stage of weatherproofing.
Purpose made groove here to screw-fix the
upstand section to your timber kerb
STEP 4:
SCREW FIX THE LANTERN TO THE TIMBER KERB
You now need to secure the upstand to the timber kerb by inserting screws into the
purpose made groove that runs around the bottom of the frame externally, about
100mm from each corner, screwing through the upstand into the timber underneath.
You will need to pre-drill your holes into the aluminium frame using a standard metal
drill bit.
We recommend a minimum of 12 screws - two at each corner,
with a further screw in the
middle of each side.
For larger lanterns, we recommend inserting
additional screws at approx. 500mm intervals.

STEP 5.1: STEP 5.2:
FLASHING GUIDELINES (Sheet membrane)
Ensure the roof membrane is tucked right under the dedicated drip lip that sits just
under the glass. This is important as it acts as the final weathering stage to avoid water
ingress in this area. Take a look at the diagram below which illustrates this detail. If
using a torch on felt, we recommend that you cut your membrane to the correct size,
fold back and pre-heat with your heat gun. Only then should you apply it to the side of
the unit. This will prevent you from damaging the unit by applying heat directly.
FLASHING GUIDELINES (GRP membrane)
If using GRP to finish the roof, you should silicone bond a 4mm plywood border around
the upstand and kerb. Screw fix this into the timber kerb if you wish to make it more
secure. This will provide a more suitable surface for the GRP to adhere to. Ensure that
this goes right up underneath the drip lip as the below image shows. Also, ensure that
the GRP layer is applied right up to and underneath the drip lip.
Your roof lantern installation is now finished.
