Frequently Asked Questions

What are 28mm glazing packers used for?

28mm glazing packers support and centre double-glazed sealed units within the frame rebate. Setting blocks carry the weight of the glass; horseshoe packers centralise it side-to-side.

Are your 28mm packers colour coded?

Yes — our glazing packers are colour-coded by thickness so installers can quickly select the correct size without measuring on site.

Do you sell 28mm packers in bulk?

Yes — trade bulk packs are available with significant per-unit savings for glazing companies and window fitters.
