What is urethan insulation?

Urethane isolation is a building product used to prevent air transfer over the outer walls of the house. It consists of polymer chains connected by organic compounds known as carbonates or urethany. The terms urethan and polyurethane are used interchangeably in terms of most applications, including insulation.

There are two basic types of urethan insulation, including a solid foam plate and spray foam. The rigid boards are supplied in different sizes and usually range from 1 to 2 inches (2.54 to 5.08 cm) in thickness. These boards are used primarily in the new construction and are installed inside the walls or around other household structures. Insulation of urethane spray foam is usually used in existing structures that may lack sufficient insulating material. This product is sprayed into the wall through small holes and quickly expands to fill the entire wall cavity.

This material can be used a number of different applications at home. On the outside of the frame systemWalling walls are often installed rigid urethan insulation, where it is inserted between the layers of cladding and the outer shell. Strict insulation leaves can also be connected to the roof or foundation of the house to provide further thermal resistance in these areas. The cutting foam is installed inside the same cavity as the walls on the wall, with clay, plywood or plasterboard used to form the wall boundaries.

Urethane insulation offers several advantages over other insulating materials. Although it is a bit more expensive than traditional glass fiber batty, it is considered an excellent insulator with two to three times thermal resistance of alternative products. The construction of closed urethan foam cells helps to block the air flow and also prevent collapse or sagging of the material. Urethan insulation leaves very occupied space, which results in thinner walls and more affordable living space. Finally, the urethhan insulation is obtThe inflammation is ignited and more resistant to fire than glass fiber or polystyrene insulation.

Despite many advantages, there are a number of factors that need to be taken into account when using urethan insulation. As it ages, this material is experiencing a condition known as a thermal drift, which can lead to a reduction in thermal resistance levels. Adding a foil or plastic coating to insulation can eliminate or slow down the thermal drift. Insulation of urethhane is also insect sensitive, which can plunge into the material and reduce its efficiency. In order to prevent insect damage, the insulation should be treated with insecticide, especially when installed on the foundation or basement walls.
