![]() The 3M VHB closed cell acrylic tapes are monolithic. Other high quality acrylic foam tapes include the AS series from Scapa and the ACX brand from Tesa. The two most common types of double coated foam tapes used for muntin bar attachment are acrylics and polyethylene.Īcrylic foam tapes include the well known VHB brand from 3M and the Norbond brand from Saint Gobain. Some design examples are show below.ĭiagram Credit: Creative Millwork Diagram Credit: Bacon Architectural Muntins Muntin Tape Options ![]() ![]() The bars themselves come in a variety of widths, heights, profiles, and colors. The bars can be supplied in lineal form to OEMs who can cut them to length and fit the bars themselves, delivered as broken down kit with one grille per bag, or in a fully assembled pattern ready to install. Muntin bars and the assembled grilles can be made from a variety of materials including PVC (vinyl), wood, aluminum (painted or anodized), and bronze. This blog post will help the owner, architect, OEM, or glazier to understand the different types of muntin bar attachment tapes and the relative strengths and weaknesses of each. ![]() There are several methods for attaching the grille or a muntin bar to the glass screw-in, glaze-in, snap-in, or tape applied. This design approach is called SDL – simulated divided lite. Should this grille, and the grille array be a window family too? Or should they be generic? Or does it matter when they are that far down the russian nesting doll? Because they aren't going to be shared.Muntin bars are designed to accent residential and commercial windows, doors, and storefronts with the look of a true divided lite for a fraction of the cost. One question: Currently all my nested families are categorized as window families (the units, jamb extensions, etc). which I have all controlled by the nested units at this point. I kinda view these grilles architecturally the same as a material choice, "yes, I want wood with 3 horizontals and 3 verticals". I'd rather have the extra types to chose from in the drop downs, then have to make all the parameters for "do you want grilles" in the window families. I wish there was a way to make the horizontals and verticals continuous, but I'll live with one slightly thicker than the other.Īlso, definitely going with nesting the grilles into the Nested Units. I can't put what they are doing into my current system.Īaron, good recommendation on avoiding the Bag of Ass look in elevations. it was helpful for a basic dimension of a grille, but starting from grille scratch is definitely the way I'm going to go. That was enough, for me to not want to do it again. Ive only downloaded a couple of manufacturer windows so far. Which, is how i think it should be documented anyway. ![]() Having them in the Nested Panes means you dont have to deal with the manual parameter, but youll need more optionable Pane Types, for variations in Muntins. Since reporters cant work backwards, youd need some hardcoded types, or a manual parameter to deal with it. Overall Window family youll struggle a lot with getting them to sit flush on the window panes, given that the shared nested window panes might move the glass (think of swapping a fixed to a DH window). There are implications to both, so think it through. What your describing just gets seated EITHER inside the Nested Panes, or in the Overall Window Family. Nested Face Based Exterior Trim Family (variable) Other than that, i would do it the way you are heading. If you go with 2 levels of nested families (the single muntins, and the muntin arrays) just be advised that you cant join geometry the muntins, so youll want to make either the verts or the horiz ones slightly thicker, so it doesnt read like a bag of ass in elevations. ![]()
