Section 1
Before you start:
• This task is accomplished more easily with two people.
• Gloves and goggles are recommended. No tools required.
• Identify all Polycarbonate panels and PVC end caps and joiners.
• Locate and identify the stainless steel clips.
• Locate spring glazing clips from the greenhouse pack.
• It is important to install the panels with the UV treated side facing outwards. This is covered
with white polythene. Suggested installation procedure:
• Remove the clear polythene protective cover from the ‘inside’ face of the panel just before
installation but leave the white ‘outside’ covering in place.
• Install the panel, peeling back sufficient of the white sheet to install the clips and end caps.
• Do not remove the white covering until the panel is finally secured in place.
Note: The glazing bead should be added to the frame
before assembly as indicated in the frame instructions.
Section 2
Glazing method: general.
• The stainless steel retaining clips are
designed to hold the centre of the
polycarbonate panels to the greenhouse
frame: There are 3 designs, each for a
specific part of the greenhouse. Where they
are needed, add the correct clip to the centre
of the polycarbonate panel ends, with the
frame-fixing part of the clip on the inside.
• The ‘U’ profile end caps are added before
glazing and fit over the stainless steel clips
where they are used. The wide face of this
profile should face outwards. Fig A.
• Have someone inside the greenhouse to help
locate the stainless steel clips onto the
greenhouse frame. This is best achieved by locating the bottom edge of the panel into the
frame first and bending the panel as shown to locate the top edge. Fig B.
• The ‘H’ profile joiner strips (J2-1) join the polycarbonate panels at the greenhouse ends. Fig C.
• Once in place, secure with spring glazing clips (G4) as shown, evenly spaced. Fig D.

Glazing: side panels (J1-1).
• On the panel top and bottom edges use stainless steel clips J4-2 and
PVC profiles J3-1 and proceed as suggested in the general glazing
instructions.
• Once in place, secure with ‘W’ glazing clips G4 as shown, four ‘W’
clips to each panel side.
• Repeat for the other side panels.
Glazing: lower panels on Greenhouse, back and front (J1-1):
• The bottom edge of these panels is treated in the same as the side panels,
using stainless steel clips J4-2 and PVC profiles J3-1. The top edges of these
panels have no stainless steel glazing clips.
• The panels furthest from the wall use the ‘H’ PVC profile J2-1 on the top edges. The
triangular panels of these sections then fit into the top of these ‘H’ profiles: see below.
• The top edge of the other large panel fits into the cross brace profile. D4.
• Add the upper panels as below before securing with ‘W’ clips. G4.
Glazing: upper panels on greenhouse back and front.
• Panel J1-10 has PVC profiles J3-1 on both top and bottom edges and stainless steel clip J4-3
on the bottom edge only.
• Lower triangular corner panels: J1-8 and J1-9 have PVC profile J3-4 on the top edge and fit
into the ‘H’ profile on the bottom edge, as described above.
• The upper triangular panels: J1-81 and J1-91 have PVC profiles J3-4 on the top
edge and J3-1 on the bottom edge, but no stainless steel clips.
• Once in place, secure panels with ‘W’ clips G4, three clips to each long
edge and 2 to short edges.
Glazing: roof.
• The roof sections each hold two glazing panels. The upper panel top
edges have no stainless steel clips or PVC profiles: they slide under the
ridge flange.
• The bottom edges of the upper panels use stainless steel clips J4-3 and
PVC profiles J3-1.
• The lower panel top edges slide under the bracing bar flange with PVC profiles
J3-1 but no clips.
• The bottom edges of the lower panels use stainless steel clips J4-1 and PVC
profiles J3-1.
• The panel below the vent is treated in the same way as the other roof
lower panels.
• Once in place, secure with ‘W’ clips G4, three clips to each panel side.
Glazing: vent.
• This section is glazed prior to installation: see greenhouse erection
instructions.
• PVC profile J3-3 can be added to the panel bottom edge by slackening
the corner bolts.
Glazing: door.
• The top and bottom edges of all of the door panels have Stainless steel clip J4-3 and PVC
profile J3-1
• Once in place, secure with ‘W’ clips G4, two per each large panel side and one on each
small panel.
NOTE: in very exposed areas extra spring glazing clips are recommended: these can be purchased
from most greenhouse retailers and are part of the Gardman Handy Pack range. In extreme
conditions ‘Sealoflex’ or other clear silicon mastic can be applied to the glazing bead during the
glazing process.
