Description:
This heavy-duty patio door shrink kit from Frost King helps reduce drafts and heat loss around sliding glass doors by creating a clear, protective barrier that tightens with heat. It is intended for larger openings and focuses on durable, puncture-resistant film and extra-wide sealing tape to secure edges for seasonal insulation and light protection.
Key Points
The film is described by the manufacturer as puncture resistant, offering durability for repeated use. This kit includes a wider sealing tape, which helps create a firmer attachment around the door frame and reduces air infiltration. The clear material preserves light while forming an insulating layer, and the product is sized for large patio doors.
Technical Specifications
- Name: Frost King V86M Heavy Duty Patio Door Shrink Kit
- Size: - 120" x 84"
- Film type: - Heavy duty, puncture resistant (according to the manufacturer)
- Tape: - Extra-wide sealing tape included
- Package: - 1 kit
Usage Recommendations
Measure the opening carefully before installation to ensure the 120 by 84 inch film covers the full door area with enough overlap for the tape. Apply the extra-wide tape to the frame evenly, position the film, then use a heat gun at a safe distance to shrink the material until it lays flat and taut. Take care to avoid prolonged concentrated heat on one spot to prevent damage.
Practical Notes
Consider that this heavy-duty film is thicker than standard window kits and may be slightly less flexible when first handled. It is useful for seasonal weatherproofing and light reduction, however it does not replace professional door replacement if the door itself is damaged or has warped framing. For best results follow the manufacturer’s instructions for surface preparation and drying times before shrinking the film.
