Yes, it is possible to install gutters on this garden house afterwards. Gutters can be installed on the roof of the garden house to collect rainwater and direct it away from the building. This can help prevent water damage to the structure and surrounding landscape. It is important to ensure that the gutters are properly installed and maintained to effectively manage rainwater runoff. **

Yes, it is possible to install drywall before renovation plastering. Drywall can be used as a base material for plastering, providing a smooth and even surface for the plaster to adhere to. However, it is important to ensure that the drywall is properly installed and secured before applying plaster to avoid any issues with the final finish. Additionally, it is recommended to consult with a professional contractor to determine the best sequence of steps for your specific renovation project. **

To install floor insulation on uneven hollow floorboards, you can use expanding foam insulation to fill in the gaps and create a level surface. First, clean the floorboards and remove any debris. Then, apply the expanding foam insulation into the gaps and allow it to expand and harden. Once the foam is fully cured, you can trim off any excess to create a smooth and level surface for installing the floor insulation. Finally, you can lay down the floor insulation material on top of the foam to provide an even and insulated surface. **

In order to install blown-in insulation, holes are drilled into the walls, ceilings, or floors of a building. These holes are typically drilled at regular intervals to ensure even distribution of the insulation material. Once the holes are drilled, the blown-in insulation material is then blown or sprayed into the cavities using special equipment, filling the spaces and providing thermal resistance. **

It is not advisable to install Styrofoam directly on the wall for insulation. Styrofoam is flammable and can release toxic fumes when burned, posing a fire hazard. Additionally, Styrofoam is not an environmentally friendly material and can release harmful chemicals over time. It is better to use alternative insulation materials that are non-toxic, fire-resistant, and environmentally friendly, such as mineral wool, cellulose, or spray foam insulation. **

To install a copper pipe without insulation under plaster, you will first need to secure the pipe to the wall or ceiling using appropriate brackets or clips. Make sure the pipe is properly supported and secured to prevent any movement. Next, carefully cut a channel in the plaster where the pipe will run, ensuring it is deep enough to accommodate the pipe. Once the pipe is in place, patch up the channel with plaster or drywall compound, making sure to smooth it out for a seamless finish. **

Installing rafter insulation on top of existing insulation between the rafters can still be worthwhile. Rafter insulation helps to reduce heat loss through the roof by providing an additional barrier. This can result in improved energy efficiency and lower heating costs. It is important to ensure proper installation to avoid any moisture issues and to maximize the effectiveness of the insulation. **

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. **
