When you’re ready to re-side your house, vinyl offers a popular and often cost-effective solution. But not all vinyl siding is created equal. You need to know the differences in thickness, profiles, and quality to avoid issues down the road.
Understanding vinyl siding thickness
Siding thickness is measured in inches, typically ranging from .040 to .055 inches. Thicker siding is more rigid, less prone to cracking, and can better withstand impacts from hail or debris. For residential use, aim for a minimum of .044 inches. Anything less might feel flimsy and could be more susceptible to damage.
Different vinyl siding profiles
The profile refers to the shape and appearance of the siding panels. Common profiles mimic traditional wood siding and include:
- Double 4-inch clapboard: Two 4-inch wide clapboards per panel, creating a classic look.
- Double 5-inch clapboard: Similar to double 4-inch, but with wider 5-inch clapboards.
- Dutch lap: Features a beveled edge, creating a shadow line for a more defined look.
- Vertical siding: Panels run vertically, offering a different aesthetic and can make walls appear taller.
Consider the architectural style of your home and the look you want to achieve when selecting a profile. For a modern look, vertical siding might be appealing, while Dutch lap offers a more traditional, dimensional feel.
Types of vinyl siding based on composition
While all are vinyl, variations exist in their formulation and construction:
Standard vinyl siding
This is the most common type, made primarily from Polyvinyl Chloride (PVC). It’s budget-friendly and comes in a vast array of colors and styles. Its main drawback can be its susceptibility to expansion and contraction with temperature changes, which, if not installed correctly, can lead to buckling.
Engineered vinyl siding
This category includes products like polymer or composite siding. These often use a blend of PVC with other materials to enhance durability, rigidity, and UV resistance. Some engineered vinyl sidings are designed to mimic the look of wood more closely, offering deeper grain textures and richer colors. They tend to be more expensive but offer superior performance.
Insulated vinyl siding
This type has a rigid foam insulation core bonded to the vinyl. The insulation provides an added layer of thermal resistance, potentially reducing energy costs. It also increases the siding’s rigidity, making it more impact-resistant and less prone to sagging or denting. This is a premium option, offering better performance but at a higher price point.
Key features to look for
Impact resistance
In areas prone to hailstorms or high winds, impact resistance is crucial. Look for siding that has been tested and rated for impact resistance, often indicated by certifications like those from the Vinyl Siding Institute (VSI). Thicker siding and engineered vinyl generally offer better impact resistance.
Color retention and UV stability
The color of vinyl siding can fade over time due to sun exposure. High-quality vinyl siding will have UV stabilizers mixed into the PVC compound, not just applied as a surface coating. This helps prevent fading and chalking. Darker colors tend to absorb more heat and can be more prone to fading if not manufactured with good UV protection.
Warranties
A good manufacturer’s warranty is a strong indicator of product quality. Look for lifetime limited warranties that cover manufacturing defects, fade resistance, and impact resistance. Understand what the warranty covers and for how long. Some warranties may be prorated after a certain number of years.
Installation considerations
Expansion and contraction
Vinyl expands and contracts significantly with temperature changes. Proper installation requires leaving small gaps at nail holes and ensuring panels aren’t over-fastened. This allows the siding to move freely without buckling or cracking. Experienced installers are vital here.
Underlayment and house wrap
Before installing vinyl siding, a weather-resistant barrier (house wrap) should be installed over the sheathing. This protects the wall structure from moisture. Some systems also incorporate a rigid foam underlayment for added insulation and protection.
Trim and accessories
Don’t overlook the trim pieces, such as soffits, fascia, and corner posts. These are often made of vinyl as well and should be chosen to complement the siding. The quality of these accessories impacts the overall look and weather-tightness of the installation.
Maintenance and cleaning
Vinyl siding is known for its low maintenance. Typically, it just needs to be cleaned annually with water and a mild detergent. Avoid using abrasive cleaners or high-pressure washers, which can damage the surface or force water behind the panels. Regular cleaning prevents the buildup of dirt, mold, and mildew, keeping your home looking its best.
Cost factors
The cost of vinyl siding varies widely based on thickness, profile, brand, and whether it’s standard, engineered, or insulated. Expect to pay anywhere from $3 to $12 per square foot installed, with premium options like insulated or high-end engineered vinyl costing more. Standard double 4-inch clapboard will generally be at the lower end of this range.
When to choose other materials
While vinyl is a great option for many, consider other materials if:
- You desire a premium, natural wood look that vinyl can’t quite replicate. Consider fiber cement or real wood siding in such cases.
- Your budget allows for more durable or aesthetically unique materials like brick or stone veneer.
- You are in a historic district with strict aesthetic guidelines that may not permit vinyl.
- You want extremely high impact resistance beyond what most vinyl can offer.
