You already have the performance make-up you wanted. How about adding an extra feature to give your units or residential windows some design characteristics. The 3M VHB closed cell acrylic tapes are monolithic. The other manufacturing technique is coating an acrylic adhesive onto both sides of a closed cell acrylic foam core. Also referred to generically as polyolefin foam tapes, these consist of a foam core made for irradiated, cross liked polyethylene that can be modified with the addition of EVA or other polymers to form a tough, versatile product.

Additional coatings can be added to the foam core to create an ultra-smooth surface for superior wet out characteristics on the muntin bars and the insulated glass unit IGU.

Although the PE foam tapes will not exhibit the same viscoelastic behavior as the acrylic foam tapes, they have low water absorption properties and exhibit good dynamic shear and tensile properties with a favorable price point that make them suitable for many muntin bar applications.

As mentioned, muntin bars are often made from PVC, wood, and aluminum. The muntin bars for residential windows are typically smaller in width, height, and weight than muntins for commercial windows. Commercial muntin bars are usually made of aluminum often painted and are usually wider and have a higher profile making them much heavier. Another consideration is coefficient of thermal expansion CTE. Simply put, this is the change in length or volume of a material for a unit change in temperature.

Muntin bars will shrink and expand as the temperature cycles down during the night and up during the day. This movement has to be accounted for when selecting a tape that will move easily with the bar and grille assembly.
