Understanding the Building Envelope This article is intended to provide an overview of the building envelope and details about its components and products. The building envelope consists of the parts of a building that keep the weather out and conditioned environment in. This …
TPO commercial roofing membranes were first specified in Europe, then made significant inroads in the North American market in the late 1990s. There have been many developments in the low-slope (flat) roofing industry, so TPO commands a considerable market share in the U.S. and Canada.
One of the most important factors in selecting the optimum flat or low-slope commercial roof insulation is designing to the desired thermal efficiency. R-value is a measurement to quantify the insulating properties of a building material. The highest R-value per inch is the best, and …
By definition, a primer comes first and serves as a base for what should follow — whether it’s attending the primary grades at the beginning of school, priming an engine to start or using a primer coat applied prior to painting a wall. …
What Does R-Value Mean? A higher R-value means that the insulation will do a better job of holding in conditioned air, whether that’s heat in the winter or cool air in the summer. It’s not about how much heat the insulation retains, but …
