Now, any water that gets past the siding and runs down the surface of the drainage plane (housewrap) will be directed to the outside of the apron flashing and then onto the roof.Ĭontractors tape is the fastener that holds the drainage plane layers in place and is not a substitute for properly lapping the layers shingle fashion. The new strip of housewrap should extend over the roofing felt and flashing as shown in the photo of the completed apron flashing.Ĭontractors tape is used to fasten the strip of housewrap where it tucks under the existing housewrap and also to hold it against the metal apron flashing until the siding has been installed over it. To avoid damage to the home, this can be corrected (photo 2):īefore the siding is installed, cut the housewrap horizontally above the roofing felt and slip another strip of housewrap up under the existing housewrap on the wall (shingle fashion). If they are not overlapped properly, or reversed, water may be directed into the building and result in a failure.Įvery element of the drainage plane must be installed so it will direct water out and over the layer below it. Starting at the foundation, every element of the drainage plane must be installed so it will direct water out and over the layer below it in the same fashion as the overlapping of shingles on a roof. The outside surfaces of windows, doors and skylights are also part of the outer surface of a building and must be carefully integrated with drainage plane components. Weather resistive barrier (housewrap or building paper).The foundation (footings and walls) drainage system.It should cover the entire house from bottom to top and includes: This protective layer is often referred to as the drainage plane. On the exterior of homes, building materials that can't stand up to repeated exposure to water must be protected by another layer. Drainage planeĪnother factor that contributes to the durability of homes is their ability to resist Minnesota weather. While some composite materials are more durable than traditional framing and sheathing materials, others are less durable and are not able to survive wetting and drying cycles as well as dimension lumber. One reason is the difference between the dimension lumber used to construct older homes and the growing number of composite materials used in newer frame construction. There are a number of reasons why older homes have endured the test of time. Today the application can no longer be downloaded for free and is that just at the time of receiving these two new versions until reaching the final 2.0.1, the developer adjusted the price in the 3 euros, so if we want to download it now we will have to go through the box.While we may complain a little about the comfort and energy costs of older homes, we also speak with reverence of their durability. So long time without performing an update to correct a small bug, bugs or add new wallpapers, it is not good for the developer and much less for the user, but now we have the new version available.Īctually, this new version provides what we users who have installed this great weather application on our Mac have been asking for: a improved stability of the app, possibility of using the location manually, some new images and a improved refresh rate so that the funds change faster adapting to the weather conditions that we have in the city where we are. The application worked fine in the previous version, but after its launch in 2013 It has only received three updates and two of them during this same month (2.0 and 2.0.1). On that occasion we complain about the lack of updates of a great application to know as wallpapers the meteorological conditions of the place where we are. At the end of December last year, the application developer, Weather Wall for Mac, allowed its free download for a limited time.
