Using Vinyl-Fiberglass Composite VS. Aluminum for Sunroom Installation

vinyl-fiberglass composite

LivingSpace is the only manufacturer on the market building composite sunrooms made with vinyl and fiberglass reinforcement. Vinyl is an excellent insulator, making it highly energy efficient. Fiberglass gives the sunroom strength and durability. Most other sunroom manufacturers use exposed aluminum as the main building component of their sunroom. Aluminum easily conducts thermal energy, making it an exceptionally poor insulator. Nonetheless, it does provide some benefits like adding structural support.

When planning for your sunroom addition, it’s important to understand each material to best judge the sunroom options available. This post goes through the cases for and against a composite sunroom and an aluminum sunroom.

The case for the vinyl-fiberglass composite sunroom

Durability: Fiberglass is an extremely strong, stable, and thermally non-transmitting building material, and vinyl is made of an exceptionally strong PVC plastic resin. Both withstand inclement elements, including heavy winds and rain. The composite sunroom resists excessive moisture, and it is resistant to corrosion over time. It also resists pests and does not rot, allowing it to keep its original qualities for many years. Because of its resistance to wear and tear, vinyl maintains its color and finish – even vibrant custom colors – and the structure only requires once a year cleaning.

Energy Efficient: A vinyl-fiberglass composite sunroom is an economical choice, as it is is a phenomenal insulator against both electrical and thermal energy. This gives the material a greater R-value, and makes it a great choice for sunrooms in regions that experience extreme heat or cold. Consequently, lower energy costs reduce the carbon footprint your sunroom creates. Furthermore, it can lower your HVAC repairs and maintenance because the HVAC system is under reduced stress.

Environmentally Friendly: This graph shows the environmental impacts of different building materials. As shown, vinyl siding is shown as the more responsible choice when compared to aluminum siding options. Wood siding is the only environmentally friendlier option. Similarly, fiberglass is designed to last for decades and is ENERGY STARⓇ rated.

The case against the vinyl-fiberglass composite sunroom

Upfront cost: A vinyl-fiberglass composite is more expensive than aluminum initially. However, the energy efficiency of a vinyl sunroom allows customers to save more money on energy costs in the long run.

The case for the aluminum sunroom

Structure: Aluminum provides strength and rigidity to a sunroom, and it is a strong material that can provide additional support when necessary. Aluminum is fairly lightweight, which allows manufacturers to make thicker and stronger aluminum pieces for an area that has a weight capacity.

Upfront cost: Aluminum is a comparatively inexpensive option. It has an ease of application, which reduces construction costs.

The case against the aluminum sunroom

Insulation: Aluminum is an exceptionally poor insulator because it easily conducts both electrical and thermal energy. This makes it difficult to properly insulate for anything other than seasonal use. Aluminum can combat, but not entirely overcome this limitation when wrapped by a superior thermally performing material, like vinyl.

Durability: Aluminum doesn’t rust, which reduces the repainting costs. However, aluminum is easily scratched. This generally happens during installation, as there are a lot of moving pieces. Even the most competent and capable installers are unable to fully prevent this from happening. Likewise, aluminum is easily dented, and backyard activities like baseball or soccer could result in a damaged sunroom.

Why LivingSpace uses vinyl-fiberglass composite over aluminum

LivingSpace values quality products and recognizes the benefits of a vinyl-fiberglass composite and aluminum. Nonetheless, it is clear that the vinyl-fiberglass composite sunroom is the superior product in terms of durability and energy efficiency. Therefore, LivingSpace builds sunrooms using this material. This allows the sunroom to best insulate against extreme heat and cold. In contrast, other companies typically build inefficient sunrooms using exposed aluminum. During extremely warm or cold months, conditioning an aluminum sunroom will most likely incur significant energy costs. This is neither efficient nor economical.

Nonetheless, LivingSpace recognizes that aluminum helps provide structural support. Therefore, aluminum is used in the LivingSpace sunroom’s hurricane header. This allows the sunroom to withstand 150 mile per hour winds. The aluminum is encapsulated by a vinyl-fiberglass composite to combat the material’s insulation inefficiencies.
