Between 1993 and 1997, design and process solutions were developed to improve the functionality and durability of the product. In 1997, one vinyl siding manufacturer launched the first full-scale commercialization of insulated vinyl siding. Between 1998 and 2003, most other vinyl siding manufacturers launched their own brands of insulated siding.

Formvar resin has a high softening point and strong electric insulation properties. It is also very flexible, water-insoluble, and resistant to abrasion. Formvar is also halogen free. Formvar resins are combustible and can cause dust explosions. For this reason exposure to heat, sparks, and flame should be avoided.
In the United States, the International Building Code and ASTM International define Exterior Insulation and Finish System (EIFS) as a non-load-bearing exterior wall cladding system that consists of an insulation board attached either adhesively, mechanically, or both, to the substrate; an integrally reinforced base coat; and a textured protective finish coat.
Funds from operations (FFO) is the term that investors use to describe the cash flow of a real estate company or a real estate investment trust (REIT). [1] FFO is a performance indicator created by the National Association of Real Estate Investment Trusts (NAREIT) that is recognized by the SEC to be the standard non-GAAP gauge of financial performance for the real estate sector.
The Differences Between Vinyl Flooring and Laminate Flooring Appearance. While both vinyl and laminate flooring are designed to simulate natural wood, they do produce slightly different final effects.
Rigid panel insulation, also known as continuous insulation [13] can be made from foam plastics such as polyisocyanurate or polystyrene, or from fibrous materials such as fiberglass, rock and slag wool. Rigid panel continuous insulation is often used to provide a thermal break in the building envelope, thus reducing thermal bridging.
[2] A vapor retarder and an air barrier serve to reduce this problem, but are not necessarily interchangeable. Vapor retarders slow the rate of vapor diffusion into the thermal envelope of a structure. Other wetting mechanisms, such as wind-borne rain, capillary wicking of ground moisture, air transport (infiltration), are equally important.
