How to drain rainwater


Choosing the appropriate fiberglass rolls: The degree of fiberglass filling varies according to the wall to be insulated. Each location of the house has its own degree of insulation, and this degree is symbolized (in English: R), where the value of the thermal resistance of the insulating

.

Fiberglass panels are used to insulate the interior walls of the house, and this is done by following the following methods:

Measurement of the total area of ​​the walls to be insulated: All measurements should be taken of the walls to be insulated, and the number of wall gaps to be insulated as well.
Choosing the appropriate fiberglass rolls: The degree of fiberglass filling varies according to the wall to be insulated. Each location of the house has its own degree of insulation, and this degree is symbolized (in English: R), where the value of the thermal resistance of the insulating material appears. The higher this value, the more efficient this material is in the insulation process.

Preparing the tools and tools needed to start the insulation process: The necessary tools should be prepared to start the installation process, which are as follows:
Multipurpose knife or scalpel.
Safety equipment such as gloves, masks, pants, and long sleeves.
Iron clamp press.


Cutting the fiberglass rolls according to the measurements: After purchasing the insulation rolls according to the measurements obtained from the site, they are carefully divided using a knife to obtain the appropriate width on which to install them.
Fixing the fiberglass pieces: Each piece of insulation is pushed into the place to be isolated, and pulled out little by little, so that the gaps are completely filled.


Fastening the insulation material: Fastening is done using iron clamps, where a clamp is installed approximately every 17.8 cm.


Use of insulation foam
Insulation foam is widely used in moisture resistance, as it is often used in basement floors and the attic floor. Here are the steps for insulation using this material:


Determining the size of the area to be isolated: The area to be isolated should be known, as this type of insulation is suitable for isolating the attic area and the lower floors, and this is done by using a low-pressure sprayer. As for closing small openings such as voids around windows, doors, etc., small spray cans can be used. .


Providing the necessary tools: A foam sprayer can be purchased from stores specialized in selling insulation materials and their accessories. Although this machine is not cheap, it can be used to isolate small areas quickly and easily, in addition to the need to obtain safety equipment, where glasses should be purchased. Eye protection and a mask, and it is preferable to wear a full work suit or replace it with sleeves and pants.


Choosing the appropriate type of insulation foam: The appropriate type of insulation foam should be chosen, as there are two types available, namely closed insulation foam, and open insulation foam, as closed foam is often used to insulate external walls; Because of its high degree of resistance and greater efficiency compared to open foam, which is often used in interior walls, and to close small holes in dry walls.


Preparing the area to be isolated: by removing the nails stuck in the walls, cleaning the debris, and preparing the wall to start the isolation process, and the gaps in the walls should be identified, from which light can be seen, or an air duct is observed through them, and it is preferable to identify them by placing a specific mark; To be referred to after completion of isolation; To ensure the quality of the isolation process.


Spraying foam in the area to be isolated: where the sprinkler is connected to the insulation bucket, then spray the foam by applying the sprinkler at a distance of approximately 60 cm, while starting to spray as if someone is washing a car, or a window, while maintaining an appropriate distance between the person and the wall, so as not to The wall is overfilled.


It is recommended to take some precautions, and follow some tips while filling the insulation foam on the walls, as follows:


Use insulation foam in appropriate quantities, so that the thickness of the layer does not exceed about 2.5 cm, otherwise the additional accumulations of this foam will lead to the occurrence of wall sclerosis, which will cause it to fall due to the weight.
Leaving the areas that were filled with insulation foam as a result of not controlling it, as excesses are easily removed using a putty scraper, and not trying to clean them, or remove them before they dry, which leads to deformation of the wall.


The possibility of obtaining an additional layer of insulation by using a new layer of foam over the old layer, after allowing the old layer to dry for an appropriate period of time, and then adding another layer on top of it; To increase the efficiency of the insulation system
