BlueTex Roll Up Garage Door Insulation Kit
The kit is designed specifically for commercial-style roll-up garage doors on metal buildings. It functions as a radiant barrier to reduce heat transfer into interior spaces. Installation is aided by included materials such as double-sided tape, seam tape, optional screws, and a utility knife, enabling a straightforward DIY setup. The product emphasizes a high reflectivity aluminum surface to drastically cut radiant heat when airspace is present, offering an “instant shade” effect for doors.
Shurtape MB 100CT Metal Building Insulation Tape
Shurtape MB 100CT is a metal-building insulation tape designed for seamless bonding and a non-permeable seal. It provides a permanent adhesion that helps maintain vapor and air barriers across joints and seams. Ideal for sealing seams on reflective foils and foam insulation, this tape supports long-term performance in harsh climates and industrial environments.
BlueTex 2mm PRO Metal Building Insulation
This 2mm PRO insulation features a pure aluminum foil layer bonded to 2mm EPE foam with a white tearproof backing. It delivers 97% radiant heat reflection when installed with an air gap. The roll width and length are designed for easy installation over 48-inch framing grids or red-iron purlins, providing substantial coverage and effectively reducing heat gain in metal buildings.
BlueTex Insulation 3″ Seam Tape
This 3-inch-wide seam tape is made in the USA and offers strong adhesion in diverse climates. It is designed to seal and repair insulation seams in metal buildings, crawlspaces, and other areas where a reliable vapor barrier is needed. The tape blends with white insulation materials and is suitable for long-term use in tough environments.
BlueTex Insulation Vapor Barrier 6mm Foil
This 6mm metal building foil and foam insulation provides a robust vapor barrier and radiant heat reflection. The product comes in a wide roll format (62 inches wide) and supports large-area coverage, making it suitable for new constructions or retrofits on metal buildings. It works well alongside seam tape for a complete vapor and thermal barrier system.
BlueTex Insulation Vapor Barrier 6mm – Alternative Roll
Like the Roll Up Kit, this vapor barrier option emphasizes reflectivity and condensation control. Built for metal buildings, it integrates with other barrier components to create a comprehensive insulation system designed to withstand industrial environments and varying weather conditions.
Buying Guide: Key Purchase Considerations
- Climate and heat load: In hot climates or spaces with high radiant heat, prioritize reflective barriers (aluminum foil facing) and air gaps to maximize radiant heat rejection.
- Barrier type: Choose between vapor barriers, radiant barriers, and complete insulation systems based on condensation risk, humidity, and interior temperature goals.
- Installation considerations: DIY-friendly options with included tapes, seam materials, and simple mounting methods save time and labor costs. Ensure compatibility with existing door types (roll-up doors, metal panels, etc.).
- Coverage and alignment: Measure framing and purlin spacing to pick rolls that minimize seams and overlaps. Wider rolls can speed installation on large walls or doors.
- Durability and maintenance: Look for tape and tape-backed foams that withstand temperature swings, UV exposure, and physical wear. Some products allow pressure washing or heavy cleaning if needed.
- Vapor management: In metal buildings, moisture control reduces risk of condensation. Combine vapor barriers with proper sealing and seam tapes for a robust air-tight system.
- Compatibility with existing materials: Ensure adhesives and tapes are suitable for your surfaces (painted metal, joists, plywood backing, etc.) to avoid delamination or poor bonding.
- Cost vs. performance: While premium reflective insulation often yields greater radiant heat reduction, assess total project cost, including accessories and potential labor savings, to determine the best value.
