Avoid Roof Leakage After a Solar installation on the Roof Have you been in a situation where, after a solar installation on your roof, it begins to leak? Yes, it could happen to the best of us if proper care is not taken. 1. Please, access that roof you want to climb. Get a carpenter to assess the roof before work begins. The carpenter checks the state of the rooftop to confirm if it can hold the weight of the panels or if it needs repair. If you don't have a carpenter, you can do this yourself. Just check for weak spots, rust, or signs of wear and tear. . 2. Use Sealant or Roof Gum Even if there's no visible damage, apply sealant—what we call "roof gum" —where you plan to drill screws into the roof. This precaution helps to create a waterproof barrier at the points where the roof is penetrated. Just go to those selling building materials and ask for roof gum. They would supply to you. It’s not expensive at all. . 3. Walk Carefully on the Roof Abeg, If the roof is old, especially in villages, avoid walking directly on the roof surface to prevent damage. It's best to walk on the "gutter part" of the roof or use a plank to spread your weight. So you would not create dents or cracks that will cause leaks once the solar panels are installed. . 4. Avoid Creating "Potholes" on the Roof When installing, take care not to create any dents that could stop the roof’s water drainage system. Imagine when rain falls and water settles in the middle of the roof due to a dent—this can lead to leaks. Please, make sure there’s a clear path for water to flow off the roof. . 5. Use Rails for Large Installations For larger installations, don't place the panels directly on the roof. Use rails to create some space between the roof and the panels, allowing for proper airflow and preventing heat buildup or further stress on the roof. Thanks for reading, and continue learning and improving.

"Soundproof PPRC pipes" likely refers to PPRC (Polypropylene Random Copolymer) pipes that are designed to reduce noise transmission compared to standard pipes. Here are some features and characteristics that may be associated with soundproof PPRC pipes: Special Construction: Soundproof PPRC pipes may have a unique construction or additional layers designed to dampen sound vibrations and reduce noise transmission through the pipe walls. Acoustic Insulation: These pipes may incorporate materials with acoustic insulation properties, such as foams or sound-absorbing layers, to minimize noise propagation within the piping system. Noise Reduction: Soundproof PPRC pipes are engineered to attenuate the transmission of noise generated by flowing fluids, such as water or air, as they pass through the piping system. This can help maintain a quieter environment in residential, commercial, or industrial settings. Applications: Soundproof PPRC pipes are commonly used in buildings where noise reduction is a priority, such as residential apartments, hotels, hospitals, schools, or office buildings. They are particularly beneficial in applications where plumbing systems are located near sensitive areas or where noise disturbance is a concern. Compatibility: Despite their soundproofing features, these pipes maintain the same compatibility and performance characteristics as standard PPRC pipes. They are suitable for use in plumbing, HVAC (heating, ventilation, and air conditioning), and other fluid transportation systems. It's important to note that the effectiveness of soundproof PPRC pipes may vary depending on factors such as pipe diameter, wall thickness, installation method, and surrounding environmental conditions. Additionally, consulting with manufacturers or suppliers specializing in soundproof piping solutions can provide more detailed information on the specific features and performance of these pipes.

Bitumen Roll Roofing Roof insulation is a crucial phase in both construction and maintenance, as it protects buildings from water leaks, reduces operational costs, and extends the building's lifespan. Among the most commonly used materials for roof insulation is bitumen rolls. In this article, we will delve into the nature of bitumen rolls, their installation method, advantages, disadvantages, and the overall importance of roof insulation. What are #Bitumen Rolls? Bitumen rolls are flexible insulating materials made from modified bitumen, a black, viscous substance derived from crude #oil. Bitumen rolls are characterized by their high flexibility and ability to adapt to temperature changes, making them ideal for roof insulation. Bitumen rolls consist of several layers, including a base layer of polyester or fiberglass, a middle layer of modified bitumen, and a protective top layer. Installation of Bitumen Rolls The installation process of bitumen rolls involves several stages: Preparation: The surface is thoroughly cleaned of dirt, dust, and grease, and any cracks or holes are repaired. Primer: A primer layer is applied to enhance the adhesion of the bitumen rolls to the surface. Installation: Bitumen rolls are unrolled onto the surface gradually, ensuring an overlap between the rolls, and the rolls are welded together using a gas torch. Protection: A protective layer of gravel or sand is applied over the bitumen rolls to shield them from sunlight and mechanical damage. Advantages of Bitumen Rolls High flexibility: Bitumen rolls can withstand movement and expansion caused by temperature changes. Water resistance: Bitumen rolls protect the building from water leaks. Long lifespan: Bitumen rolls have a long lifespan of 20 years or more. Easy installation: Bitumen rolls can be installed quickly and easily. Affordable: Bitumen rolls are considered economical insulating materials. Disadvantages of Bitumen Rolls Affected by extreme heat: Bitumen rolls may be damaged by extremely high temperatures. Requires skilled installation: Bitumen rolls should be installed by specialized technicians. Not resistant to severe mechanical damage: Bitumen rolls may be damaged by severe mechanical impacts. Importance of Roof Insulation Leakage protection: Roof insulation protects the building from water leaks that can lead to moisture and damage to the building. Thermal insulation: Roof insulation reduces heat transfer from the outside to the inside and vice versa, saving on air conditioning and heating costs. Sound insulation: Roof insulation reduces the transmission of sound from the outside to the inside and vice versa, providing a quieter environment. Protection of the building from weather elements: Roof insulation protects the building from various weather elements such as rain and ultraviolet rays.

How to specify a quality thermal envelope in Australia: Background: As you know, currently in Australia, the installation of insulation and building sealing is completely self-managed by builders and not at all required to be verified by any authority! No surprise there is very very likely a huge performance gap between energy rating and actual built results! There is room for improvement. Architects can avoid this pitfall by improving the process: oblige the builder (i.e. write into specification or special condition in contract) to undertake the `As-built verification` (ABV) assessment developed by Sustainability Victoria. The ABV on-site assessment is made up of 2 components: 1. Insulation integrity inspection. 2. Blower door test. Note that the ABV assessment process relies on EXISTING standards and test methods including thermography and blower door testing as set out in AS/NZS ISO 9972:2015 ‘Thermal performance of buildings – Determination of air permeability of buildings – Fan pressurization method’. So, builders *should* be familiar with them already. During the design stage, architects are guided by handy ABV checklists. They will help you nominate appropriate components. Find more info here: https://lnkd.in/gnTr9btJ If you want to notch up a bit: sign up a Passivhaus professional early in the design process and commit to Passivhaus Certification, which will ensure a high performance thermal envelope in even greater details (bridge-free design, condensation risk mitigation, high performance fenestration) and holistically gives you a super-comfortable home, low energy bills and a healthy indoor air quality.

Monitoring Water Consumption and Leaks What is RECOMMENDATIONS? Note that for single-family homes with only one water supply to the home, the inspector will attach a pressure gauge to an outside faucet, take a reading and then shut off the municipal water supply to the house. After several minutes, the inspector will determine if the pressure has dropped. A loss of pressure indicates an unseen leak. For homes with more than one water supply or without an outdoor faucet, inspectors will attach a pressure gauge to the cold water faucet for the washing machine hookup or other cold water faucet and take the pressure reading. Conducting a pressure- loss test on dwelling units in multifamily buildings will vary based on the plumbing system design. Dwelling units that are supplied through a single line with a shut-off can be tested at any point of use. The pressure loss test can most easily be done here at a washer hookup or at any fixture using an adapter. For buildings that use riser pipe layouts, the test is simplest at the whole building level. As a first step, when designing the plumbing system for a multifamily building, consider supplying each unit with a single pipe source and stubbing out for a meter to facilitate individual unit submetering.  This will reduce costs associated with having to install multiple meters/monitors for several points of use attached to a single riser pipe. When selecting equipment that is best suited for accurately measuring water use in each unit, note that water use within individual units will fluctuate between low and peak flows depending on the unit’s occupancy and the time of day.  We recommend positive displacement meters, but consult with the meter or monitor manufacturer to select an appropriately sized device for the application. The building’s and the individual units’ size, function, fixture types, usage, occupancy, and peak population will influence minimum and maximum flow rates and proper sizing. Note that improper installation can lead to metering/monitoring inaccuracies. In general, we recommend installing meters and/or monitors in an accessible location to allow for reading and repair and in a location protected from potential damage. To ensure uniform flow entering and exiting the meter or monitor, we recommend locating the monitoring device where there is sufficient length of straight pipe before and after the device. Consider installing a strainer to prevent debris and sediment from entering the meter/monitor and causing reading inaccuracies.
