Siding and cladding are two popular exterior wall coverings that protect homes from the elements and provide insulation, but they differ in design and application. Siding is applied directly to a home’s exterior, providing some insulation and basic shielding from the elements. In contrast, cladding is installed indirectly over furring strips, creating a ventilated air gap for enhanced insulation and moisture control.

While almost nothing is completely fireproof, metal siding is extremely fire-resistant. It’s non-combustible so while it may eventually melt in extreme temperatures, it won’t actually light on fire itself. This can add a layer of safety to structures that wood or vinyl siding can’t, making it attractive for industrial use. Metal siding can significantly slow down the spread of a fire, giving extinguishers and firefighters a much better chance at saving the structure and containing the blaze. 

To calculate how much siding you need for exterior walls, first measure the height and width of the rectangular walls. For the triangular gable walls, measure the width and then the height from the ground to the tallest gable point.

• For the rectangular walls, the calculation is: length x height

• For the triangular gable walls, the calculation is: (length x height) / 2

Once you add these up, include an additional 10% to account for any wastage.

You should plan to stain or refinish your home's cedar siding every three to seven years to maintain its appearance and provide maximum protection, though some estimates suggest a range of four to six years. The exact frequency depends on several factors, including your local climate, exposure to severe weather like direct sunlight, rain, and wind, the quality of the initial stain application, the type of stain used, and the overall condition and quality of the wood.

For homes in harsh climates with high humidity and significant sun exposure, you should plan on staining as often as every three years, while those in milder locations may only need to do so every seven years. For the longest-lasting protection in particularly harsh climates, consider using an opaque stain.

If you are looking for a lower-maintenance alternative, you might consider vinyl or aluminum siding. While the initial installation cost can be higher, they do not require as much upkeep and can offer more value over time, especially in areas with excessive rainfall or high humidity.
