Reglazing With TwinWall or TripleWall

BACK | MORE TIPS

Upgrade
your greenhouse

TwinWall is a significant
improvement for a single-glazed greenhouse.

  • Remove old
    glazing
  • Cut TwinWall
    to size using a box knife or a very fine tooth saw blade
  • Install
    new glazing gasket if necessary
  • Note panels
    have one side which must face the sun
  • Remove protective
    film from inside face
  • Close exposed
    ends of panels with TwinWall capping
  • Set TwinWall
    panels in place and secure with the same method as the old glazing.
  • Now immediately
    remove exterior protective film
  • Never store
    TwinWall in direct sun
    or film will not release
  • Apply clear
    sealant where TwinWall tucks into frame or capping.

 

Adding TwinWall or TripleWall to your wood framework is easier when
using these special pieces to hold the
panels in place. The Caps are made of
a tough, sunlight resistant polycarbonate,
and are weatherproof and maintenance-free.

Use End Caps on the top and bottom
of TwinWall or TripleWall to close the
channels. This keeps out dirt and insects.
Also use End Caps on the outside edge
of corner panels (Fig. 1).

The Joiner Cap is used to connect
TwinWall or TripleWall along vertical
edges (Fig. 2).

Builder’s notes: Drill Caps every 12″
for screws. Design framework 24-1/2″
O.C., or plan to rip TwinWall to 23-3/4″
wide. Cut capping with hacksaw.
