Vinyl Siding / Vinyl Cladding
Vinyl Siding / Vinyl Cladding is extruded from polyvinyl chloride homopolymer resin and blended with exclusive technology impact modifiers, forming an extremely tough, long-lasting cladding.
The colour is saturated through the product. Vinyl Cladding contains a colour protection formulation that uses the most advanced colour retention technology available. This means the cladding never needs painting. Vinyl Siding will not dent, peel, flake, chip, blister, rust or corrode. It will hide scratches and is virtually maintenance free.
Vinyl Siding has been firmly established in Canada, the US, Australia and East Europe for over thirty years. Since the early days, vinyl siding has come a long way in production materials, durability, installation techniques and style options. Today, it is quickly becoming the best choice for home owners, historic renovation, commercial building, public house, contractors and builders. Vinyl siding is now used in approximately *0% of the market and in continuing to grow in popularity.
Vinyl Cladding will withstand extreme temperatures from **0°C to *5°C. It will not be adversely affected by extreme weather conditions. The application system allows for flexibility so it will not creak and groan with temperature change like conventional plastic systems and it does not buckle and bow.
Vinyl cladding has a moisture release system allowing it to be applied in any weather and to almost any surface. The system includes soffits, fascias and trims to suit all applications, whether domestic or commercial.

Vinyl siding for your exterior is an ideal choice due to it\'s durability, beauty and affordable pricing. Vinyl siding requires minimal maintenance, never needs painting, is easy to clean and generally last between *0 and *0 years. It is also impervious to water and bugs and can vent moisture. Vinyl siding has a wide variety of styles and color combinations to meet the look you are trying to achieve. The cost of vinyl siding is usually cheaper than wood and will cost less for installation.

Installation of vinyl siding / vinyl wall cladding
The warranty given by the manufacturer will give you a good idea of how the product will handle severe weather. Different areas may have different wind codes that the manufacturer must live up to in order for installation of their product. One option, KRS vinyl cladding comes with a ***-mph wind resistance guarantee when nailed properly.
Whether you are using tools to fasten your vinyl siding to a barn, house, mobile home, steel structure, cabin or shed, you must be careful not to fasten the plastic panel to tight to the structure. Vinyl siding must literally hang from the side of the structure. The product must be free to move as it needs to be able to contract and expand with temperature changes. A **-foot length of plastic siding can expand up to 5/8 inch. If this plastic siding is nailed to tightly to a structure, it can buckle on a hot day. If you are wondering how to install vinyl siding so it doesn\'t buckle, you will not want the nailheads to contact the hem. They should be left about 1/*2 inch proud. However, if nailed to loosely during installation, the plastic panels will rattle and be noisy when the wind blows.
If you are learning how to install vinyl siding, you will also wan to be careful of how close the plastic panels are to the trim. The plastic panels should not be butted tight to the trim. A quality conscious installer will leave about 1/4 inch of clearance, or 3/8 inch in temperatures that reach below *0°F. At the end of plastic panel courses, at corners and door and window openings a trim piece called J-channel covers and conceals the resulting gap. You can ask your installer what measurements they use to get an idea of their quality. Other trim pieces offered by manufacturers to fit their custom vinyl siding options to improve appearance after installation include soffits, rake boards and crown moldings. J-channels are one characteristic of vinyl that distinguishes itself from metal, wood (cedar, pine, etc.), aluminum, steel, cement, stone or log options.
Another characteristic specific to vinyl siding and not to wood or metal is that the plastic panels overlap. Wood or cement siding meet in an unobtrusive butt; however, vinyl panels overlap by about 1 inch where they meet. The result is obvious vertical lines. There are two items that make these vertical lines even more obvious: thicker vinyl and double or triple widths of clapboards. Contractors with a focus on quality will have techniques to make the vinyl siding look seamless after installation. A quality installer will orient overlaps away from dominant views of the house. For instance, they will run the panels from the back corner to the front of the house or on the front of the home, the panels should be installed so it is seamless from a person approaching the front door.
