To avoid problems caused by excessive rainfall, it is important to seal window leaks, the main focus of infiltration, with silicone-based sealants, a suitable material for the frame seal, gutters, expansion joints and facades. The use of silicone at the ends of an external window eliminates 90% of infiltrations
The silicone seal is resistant to thermal expansion and contraction, wind oscillations and seismic movements and does not represent high costs. Silicone sealants are easily found in building material stores and are often marketed in tube type containers with a dispensing nozzle, which facilitates the application process.
Prior to application, check the surface type to choose the ideal silicone sealant and ensure its performance. In the case of concrete and aluminium, the most indicated products are the neutral cure. Acetic curing sealants (which release vinegar odour) should be avoided in concrete or cement applications.
