Exposure to full sun can significantly impact the longevity and appearance of your exterior door. It's crucial to choose a door type that can withstand the harsh effects of direct sunlight without fading, warping, or cracking. Let's explore the best types of exterior doors for full sun exposure.
Exterior doors subjected to full sun face several challenges, including intense heat, UV rays, and thermal expansion. Here are two primary considerations when choosing the ideal door for such conditions: material and design.
Optimal Door Materials for Full Sun
Certain materials excel in withstanding the sun's rays better than others. Here are two top contenders:
Fiberglass
Fiberglass doors are excellent choices for full sun due to their durability, low maintenance, and resistance to wear and tear. They don't fade, warp, or crack under prolonged sun exposure. Moreover, modern fiberglass doors can mimic the grain of wood for an attractive, natural appearance.
Fiberglass doors also offer excellent insulation, making them suitable for both warm and sunny climates. However, they may be more expensive than other door materials.
Steel
Steel doors are robust, energy-efficient, and affordable. Galvanized steel or doors with a galvanized Stahl coating can withstand high sun exposure without rusting or fading. To further enhance durability, consider steel doors with a foam core for added insulation.
While steel doors resist sun damage well, they can dent or scratch easier than fiberglass or wood doors. Make sure to choose a door with a quality paint finish that can bear the elements.
Door Design for Full Sun
In addition to material, the door's design plays a significant role in how well it cope with full sun.
Thermal Expansion
Heat causes materials to expand, so the door's frame and jamb should allow for this expansion. Oversized doors and clearance allow the door to swell in the summer without binding or sticking. Thin interior storms can also accommodate thermal expansion and help regulate indoor temperature.
Additionally, consider installing the door with a slight outward swing to accommodate expansion without binding against the frame.
Solar Shielding
Certain door designs can help block or reflect the sun's rays, reducing their impact on your door. Solid or semi-opaque doors can provide robust shielding, while glass doors with solar reflective coating can minimize UV damage.
On the other hand, doors with large glass panels may necessitate tinted glass or retractable shade options to protect them from the sun's rays. However, these features might add to the door's cost.
Indeed, choosing the right exterior door for full sun can protect your home's aesthetic appeal and energy efficiency. Consider consulting a professional door supplier or installer for personalized advice tailored to your specific needs and local climate.
