Curved skylights offer stunning natural light, but they can also lead to significant heat gain and UV damage. Installing solar film on the exterior of a curved skylight is a great way to mitigate these issues, but it presents unique challenges compared to flat surfaces. This guide delves into the intricacies of this process, providing you with the knowledge and confidence to tackle the job successfully or determine if professional help is needed.
Why Choose Exterior Solar Film for Curved Skylights?
Exterior solar film offers several advantages over interior application, particularly for curved skylights:
- Superior Heat Rejection: Exterior film blocks heat before it enters the building, significantly reducing cooling costs and improving energy efficiency.
- Extended Film Lifespan: Shielded from scratches and general wear and tear, exterior film typically lasts longer than interior film.
- UV Protection: Exterior film provides superior UV protection for your skylight and the interior furnishings below, preventing fading and damage.
- Improved Aesthetics: While some may find the film noticeable, the improvement in comfort and reduced glare can often outweigh aesthetic concerns.
What Type of Film is Best for Curved Skylights?
Choosing the right film is crucial. For curved applications, you'll need a film with superior flexibility and conformability. Look for films specifically designed for curved surfaces; they're often thicker and more durable than standard films. Consult with a window film specialist to determine the appropriate film type based on your specific skylight's material (glass, polycarbonate, etc.) and your desired level of heat rejection and UV protection.
Preparing for Installation: A Step-by-Step Guide
1. Safety First: Always prioritize safety. Work with a partner, use appropriate safety equipment (gloves, eye protection), and ensure the skylight is securely accessible using scaffolding or a suitable lift.
2. Cleaning the Surface: Meticulously clean the skylight's exterior surface. Use a non-abrasive cleaner and a soft cloth to remove dirt, grime, and any loose debris. Thorough cleaning ensures optimal film adhesion.
3. Measuring and Cutting: Accurate measurement is paramount. Carefully measure the skylight's dimensions, accounting for its curvature. Allow extra film for overlap and potential adjustments during installation. Use a sharp utility knife or specialized film cutting tools for precise cuts.
4. Applying the Film: This is the most challenging aspect. Because of the curvature, applying the film requires patience and precision. Start from the center and work outwards, smoothing out air bubbles and wrinkles as you go. A squeegee designed for window film application is essential. Don't rush this step; take your time to ensure a flawless finish. Consider using a heat gun (carefully!) to help the film conform to the curve. However, using too much heat can damage the film.
Can I Install Solar Film on a Curved Skylight Myself?
This depends on your comfort level with DIY projects and the complexity of your skylight's curvature. Simple curves might be manageable for experienced DIYers, but highly complex curves or large skylights may require professional installation. If you're unsure, it's always best to consult a professional window film installer.
How Much Does Exterior Solar Film Installation Cost?
The cost of professional installation varies greatly depending on factors like the skylight's size, shape, accessibility, and the type of film used. Request quotes from several reputable installers in your area for accurate pricing.
How Long Does Exterior Solar Film Last?
With proper installation and care, exterior solar film can last for many years, often a decade or more. However, its lifespan can be affected by factors like exposure to extreme weather conditions and the quality of the film itself.
What are the Potential Problems with Exterior Solar Film Installation on Curved Skylights?
The primary challenges include:
- Difficulty in Conforming the Film: Achieving a smooth, wrinkle-free finish on a curved surface requires skill and precision.
- Air Bubbles: Trapped air bubbles can detract from the film's appearance and compromise its effectiveness.
- Seams: Seams between film sections need careful attention to ensure a seamless and waterproof finish.
- Damage to the Film: Improper handling or excessive heat can damage the film during installation.
By carefully following these guidelines and seeking professional assistance when needed, you can effectively install solar film on the exterior of your curved skylight, reaping the benefits of improved energy efficiency, UV protection, and reduced glare. Remember, safety and precision are key to a successful installation.
