Insulation of walls inside the foam: what you need to know before starting work?
One of the main advantages of internal insulation is that you can easily do the installation work yourself. For this, you do not need to know any particular technology. Follow the rules that we describe below. Before starting, it is important to determine how this procedure will be effective and expedient. After all, if you have serious cracks between the windows, then no additional insulation will help, because the cold air will constantly come from there.
So, first of all pay attention to the tightness of windows .Secondly, see if there are any gaps between the doorway and the wall, and between the windows and the wall. If any, they must be sealed with assembly foam, and after the cement composition. And, third, check the quality of the heating system. Older radiators are better to replace , you can also increase the number of sections in them. After all, with poor heating, no insulation materials will help.
Internal foam insulation: prepare the
base Before starting work, it is important to prepare a number of mandatory tools and materials: a cement-based adhesive, foam, an antifungal primer, reinforcing mesh and tape, umbrellas( or fungi), spatulas, roller, drill or perforator, nazhdachku, container for priming. Then proceed to prepare the foundation. First you need to remove the past coverage. For this you need to know how to remove old plaster, paint.
All nails or screws are removed from the walls. The appeared holes are covered with alabaster. Next, the surface should be washed and wait until it dries. The existing fungus or rust is eliminated. If the base has any depressions or flaws more than 1 cm deep, align them. When large irregularities use plaster, with small - putty, then the substrate is primed. As a result, the surface must be flat, dry and clean.
How is the foam plastic insulated walls inside?
The base is prepared, it's time to apply foam for internal works. Begin installation from the bottom far corner. Apply the first plate and make holes in it. Then drive an "umbrella", the hat of which should fit tightly to the heater, do not "vtapivatsya" and do not "stick out."After driving the dowel into the middle of the umbrella( to better fix the material on the surface).On one slab of foam plastic, should be located from 5 to 6 "umbrellas" of .
It's hardest to mount the last piece of insulation in the row, since it will be important to fit it in size. For cutting, you can use an ordinary knife or a hacksaw. At the next stage, when all the insulation is applied, they begin to seal the seams. Small gaps blow out with foam. Large - lay small pieces of polystyrene. Using an adhesive compound, they cover up the seams and hats of "umbrellas".Joints are coated with a solution not more than 2 mm thick.
Then reinforce the tape. After the same composition is applied to a certain surface and a reinforcing mesh is attached to it, it is as if embedded in the glue. When all this is dry, you need to process the sandpaper. At the final stage, they start decorating, choosing any finishing material( this may be plaster).On this insulation of walls with polystyrene from the inside, video with step-by-step instruction of which is presented on our website, is over.
Note! It is better to use a heater with a block width of 5-10 and 20-25 centimeters.
