Frequently Asked Questions
Frequently asked questions.
Get answers to the most common questions about 38mm insulated rolling shutters.
01What is a 38mm insulated rolling shutter slat?
The 38mm Insulated Slat is Roll-A-Shield’s most popular rolling shutter profile — a rolled-aluminum slat filled with a high-density insulating foam core. At 1.5 inches of slat height (1.8 inches total with the interlock), it’s a lighter-duty profile than our 55mm and 63mm lines, built for openings up to 12.1 feet wide. It comes in 7 colors and supports every operator type we offer, from manual pull strap to full motorization.
02What is the difference between 38mm and 55mm insulated slats?
Both use a rolled-aluminum, foam-insulated design. The 38mm slat is 1.5 inches tall and spans openings up to 12.1 feet wide; it supports manual (pull strap, crank), spring-loaded, battery, and motorized operation. The 55mm slat is 2.2 inches tall, spans openings up to 18.5 feet wide, and is available in electric/remote operation only. In short: choose 38mm for standard windows and doors under 12 feet where manual operation matters, and 55mm for larger openings or when maximum insulation and span are the priority.
03Which slat is better for patio doors?
It depends on the opening. For standard sliding patio doors under 12 feet wide, the 38mm Insulated Slat is a great fit, especially if you want the option of a manual pull strap or crank for everyday use. For wider patio openings, multi-panel doors, or when you want the extra insulation and noise reduction of a thicker slat, the 55mm Standard Foam-Filled slat is the better choice. Our team can confirm the right fit during your free on-site estimate.
04Do insulated slats reduce heat?
Yes. The insulating foam core inside the 38mm slat reduces heat transfer through the window or door opening by up to 70%, keeping interiors cooler in summer and helping lower cooling costs.
05Do insulated slats reduce noise?
Yes. The 38mm Insulated Slat adds up to +10 dB of noise insulation, and can cut outside noise by up to 50% when the shutter is closed — especially effective when there’s an air gap between the shutter and the window glass.
06Are insulated slats hurricane rated?
No. The 38mm Insulated Slat carries a Wind Resistance Class 4 rating, tested to wind loads up to 45 mph on openings up to 8.5 feet wide — solid protection for everyday Arizona wind and monsoon conditions, but it is not a hurricane-impact-rated product. For hurricane zones or maximum wind-load requirements, Roll-A-Shield offers a 63mm Single-Wall Extruded aluminum shutter rated for high-wind and impact protection. See our metal security shutters page for that option.
07Are insulated slats available in vented versions?
Yes. The 38mm Insulated Slat is available in both vented and non-vented configurations. Vented slats allow airflow and visibility while maintaining protection; non-vented slats are solid for maximum privacy and light-blocking. See the full configuration options above.
08How wide can insulated rolling shutters be?
The 38mm Insulated Slat spans openings up to 12.1 feet (145.7 inches) wide and 12.5 feet (149.6 inches) tall, for a maximum area of 86.1 square feet. For wider openings, our 55mm Standard Foam-Filled slat spans up to 18.5 feet, or a project can be split across multiple shutter units.
09What colors are available?
The 38mm Insulated Slat is available in 7 colors: White, Sand, Beige, Grey, Metallic, Bronze, and Black. All finishes are fade-resistant and built to hold up under Arizona sun.
10How long do insulated rolling shutters last?
Roll-A-Shield 38mm Insulated Slat shutters are built from durable rolled aluminum with fade-resistant finishes designed for decades of everyday use. Every shutter is backed by our warranty: 5 years on shutter parts, 5 years on motors, 2 years on electronic components, and 1 year on labor, from the date of installation.
