glazing (glay'-zing): glass used for windows or the act of installing glass into a window.
Glazing tape is used to create the inside (and sometimes the outside) seal between the
insulated glass panel and window sash or door material, preventing air and water leakage. It is more commonly
used in vinyl and aluminum windows and doors, although it can be used in wood windows and doors as well.
LAMATEK is an authorized converter for Adchem's AAMA verified glazing tape, which is ideal for use in
standard window and door applications due to it's relatively low cost and flexibility.
The most common application of glazing tape is to apply it to the sash lineals before
cutting and seaming them. This provides quick and easy application, but often requires
a small dab of some other sealant, like silicone, in the corners where the tape has been
cut. Some window manufacturers have discovered ways to apply the tape to the sash after it has
been seamed, providing a more consistent tape bead around the sash.
Another possible application is to apply the tape to the glass first, then inserting the
glass into the finished sash.
LAMATEK's glazing tape is provided in slit rolls, most commonly 1/2" and 3/8" wide, on a
3" core tubes to fit most common glazing tape application machinery. Our tape also comes with
a tough, tear resistant blue poly liner, making the removal of the tape liner easier and minimizing
the chance of liner tearing during installation.
Our type 1 glazing tape is made from special tape grade polyethylene foam, designed specifically
for adhesive coating applications. The product is available with two adhesive systems:
- GT Series
- Utilizes high strength, long life acrylic adhesive on both sides, designed to bond to vinyl, aluminum and glass.
- HGT Series
- Utilizes a high strength, long life acrylic adhesive on the liner side (for bonding to glass), and a durable high tack rubber based adhesive
on the exposed side (for bonding to vinyl and aluminum).
Both the GT and the HGT Series tapes are available with white or black foam.
Our SGT Series structural glazing tape is made from either an 18 or 25 lb./ft3 PVC foam with an aggressive
acrylic adhesive on both sides. Our structural glazing tape is available in black only.
