Downpipe bends for gutters typically have a 90-degree angle. This angle allows for efficient water flow from the gutter down the downpipe and away from the building. It helps to prevent clogs and ensures proper drainage during heavy rainfall. The 90-degree angle is a standard design for downpipe bends in gutter systems. **

The amount of insulation required for a facade renovation depends on various factors such as the climate, building codes, and the existing condition of the building. In general, the insulation should be sufficient to meet the energy efficiency requirements of the building and to improve its thermal performance. It is important to consult with a professional architect or engineer to determine the specific insulation needs for a facade renovation project. **

The roofing underlayment serves as a secondary layer of protection against water infiltration and helps to prevent leaks in the roof. It also provides an additional barrier against wind-driven rain and snow. In terms of insulation, the underlayment can help to improve the overall energy efficiency of the roof by reducing heat loss and preventing drafts. Additionally, it can provide a smooth surface for the installation of the final roofing material, such as shingles or tiles. **

When renovating a roof for thermal insulation, it is recommended to consider adding insulation materials such as fiberglass, cellulose, or foam board. These materials can help reduce heat loss and improve energy efficiency. Additionally, sealing any gaps or cracks in the roof structure can prevent air leakage and further improve insulation. Lastly, installing a reflective roof coating can help reduce heat absorption and keep the interior of the building cooler. **

I don't have personal experience with Innerseal for basement waterproofing, but I have heard positive feedback from some homeowners who have used it. Innerseal is known for its ability to create a strong barrier against water infiltration in basements, and many people have found it to be effective in preventing leaks and moisture problems. However, as with any waterproofing product, it's important to thoroughly research and consider all options before making a decision. It may also be helpful to consult with a professional waterproofing contractor to determine the best solution for your specific basement needs. **

If shoes have blue stains after waterproofing them, it is possible that the waterproofing product used contained a dye or colorant that transferred onto the shoes. To address this issue, it is important to carefully read the instructions on the waterproofing product and ensure that it is suitable for the material of the shoes. If the stains persist, it may be necessary to try a different waterproofing product or seek professional help to remove the stains. **

If shoes have blue stains after waterproofing, it is possible that the waterproofing product used contained a dye that transferred onto the shoes. To address this issue, you can try gently wiping the stained areas with a damp cloth to see if the stains can be removed. If the stains persist, it may be necessary to seek professional help or use a stain remover specifically designed for the type of material your shoes are made of. It is also a good idea to carefully read the instructions on the waterproofing product before using it to prevent similar issues in the future. **
