The Benefits of Simulated Divided Lite (SDL) Muntin Tapes

Many modern windows feature SDL grilles on the exterior or interior of the glass, creating the appearance of divided lite window panes. The SDL grilles are held in place by a polyethylene foam tape, which has a specialized high-performance acrylic adhesive system developed specifically for SDL muntin bar applications and does not require isopropyl/silane pretreatment for adhesion to glass or ceramic surfaces. This type of tape offers several advantages over traditional methods for holding muntins in place. They are an excellent solvent-free alternative for adhering wood, painted aluminum, and PVC-extruded SDL grilles to windows. Let’s take a look at some of the benefits that SDL muntin tapes offer.

Cost Savings
The cost savings associated with using SDL muntin tapes is one of the primary reasons why they are so popular among window manufacturers. Our 3000 and 4000 series Polyethylene (PE) foam tapes are relatively inexpensive compared to other methods, such as mortise-and-tenon joinery and wood caming. Additionally, because these tapes require no additional material or labor costs to install, companies can save even more money and time in their manufacturing processes.

Strength and Durability 
SDL muntin tapes are required to be strong and durable in order to use them in window manufacturing applications. At Adhesive Applications, our SDL muntin tapes are coated on both sides with a high-shear and UV-resistant acrylic-based adhesive. These foam tapes have very high tensile strength properties, which allow them to withstand both heat and cold without breaking down or deteriorating over time. In addition, the adhesive properties provide dependable adhesion performance combined with high holding power for demanding applications. Our SDL muntin tapes are highly conformable to glass and muntin surfaces with excellent foam tape-to-surface wet-out. No silane pretreatment needed.

Easy Installation
Installing SDL tapes is also much easier than making joinery cuts or assembling wooden frames since there’s no need for cutting tools or saws. All you need to do is apply the tape to the top of the glass panel where the muntin grilles will be placed and then press it firmly until it adheres properly to the surface. This makes installing SDL muntin tapes fast and easy, allowing companies to finish their window production processes a lot quicker and more efficiently.

Testing Standards
At Adhesive Applications, we believe in the importance of extensive testing to ensure our products are exceeding the highest standards in the industry. Our 3000 and 4000 series SDL muntin tapes have been tested at major window manufacturers and passed FGIA/AAMA 813-19 standards.

These products are available in white, black, and grey foam — grey being the most desirable by many window companies for its aesthetics. SDL tapes are available in long-length rolls and spools. Contact us today to learn more about our capabilities and to find out how we can customize SDL muntin tapes to meet the needs of your project. 

In conclusion, simulated divided lite (SDL) muntin tapes provide several benefits that make them an attractive option for window manufacturers looking to save time and money on their manufacturing processes while still producing high-quality results that will last for years to come. They are relatively inexpensive compared to other solutions, very strong and durable due to their special materials composition, and easy to install without requiring any additional tools or labor costs—all reasons why SDL muntin tapes have become so popular among window manufacturers everywhere!
