PVC Window Jamb Extensions

---

Our PVC Window Jamb Extensions (W.J.E.) are the quick and stress free solution to finishing off your window jambs. Gone are the days of MDF jambs that require painting and often get wet and rot in only a few years.

We manufacture W.J.E. made to fit your windows and pre-assemble them so you simply lift them into place. 

Using our W.J.E. order form, you give us your height, width and depth of each window. We manufacture your W.J.E. to fit perfectly against your wall (despite warps in the wall) eliminating the need to router the W.J.E. to fit your window trim.

Simply apply the supplied specialty silicone to the window and put the W.J.E. in place. 

Once the W.J.E. is installed, secure in place using our unique clips which eliminate the need for fasteners through the PVC face. These clips allow the installer to easily adjust the jamb to make level. Once the silicone is set, remove the clips to reuse.

Now that the clips are removed, the window is ready for trim. 

Our PVC W.J.E. allow the home owner to achieve higher efficiency by spray foaming behind the jamb if desired.
