Installation Instructions

Once you have received your new Wynne Window, follow these installation instructions.

Step 1

Clean dust and oil from around rough opening.

Step 2

Remove window from crate and position on a clean, non-abrasive surface. Position clamp ring facing up.


Step 3

Remove all clamp ring screws (making an index mark on 2 piece clamp rings will help insure correct replacement).


Step 4

Wipe window flange with dry cloth to remove dust, then install bedding compound.

For bedding compound use:

  • Butyl rubber tape
  • Double stick closed cell foam tape
  • 100% silicone rubber sealant

(Do NOT use an adhesive)


Step 5

Position window in rough opening from outside making sure of correct placement. All sliding windows must have drains toward bottom.


Step 6

Reinstall clamp ring on inside, taking care to use existing screw holes.

Note: When using silicone bedding, do not fully tighten clamp ring until silicone is dry. Over tightening when wet WILL cause leaks.


Step 7

Remove excess bedding compound.


Step 8

For acrylic or polycarbonate glazing only, remove protective masking immediately after installation. Delay or exposure to sunlight (UV rays) will make masking removal difficult.
