Aluminum alloy window below the gap 2 cm high first with fine sand cement filled outside after playing glass glue or must use a blowing agent?
In fact, can be, but only with a styrofoam only a simple seam.
It is recommended to use cement mortar bar, good physical properties, styrofoam is only simple to provide seamability.
But remember to wait for the material after curing and then sizing, cement at least a week, styrofoam on the 24 hours just fine, but personally do not consider the duration of the cement mortar or good.
How your window is fixed, if the lower part of the strength requirements, then the best use of blowing agent + glue, window windowsill than the interior windowsill slightly lower, to avoid water leakage. Mortar is easy to crack, leaking rain.
If it is to build units to do, naturally hit the bubble. If it is your own home, it is recommended that you fill directly with mortar. Because the foam only filling effect, that point do not expect his gas to keep warm. I suggest you put the window on both sides of the wall shovel shovel 60 cm high, revealing inside the foam, the foam to dig out, then the following window to the ground between the wall shovel. With Lauer or hydraulic grams and cement re-wiped again, will play to prevent the outside of the rain busy infiltration.
I have come across a lot of households have varying degrees of penetration of the windows of the phenomenon, if the property after you to deal with them, they will only be on the outside to hit the glass glue, the temporary role.
