INSULATION FACADE WITH INJECTION CAMERASFACADES REHABILITATION BY FILLING CHAMBERS
The thermal insulation of faades injection chambers is one of the techniques used in the thermal rehabilitation of facades composed of a double sheet with an air chamber accessible from the inside or from the outside in which the thermal insulator is injected.
For the facade insulation injected cameras run properly and be effective it is necessary that certain conditions:
The outer surface of the facade must be in perfect condition so you have to perform a thorough inspection to rule out any cracks or fissures and in case there are necessary to conduct the relevant rehabilitation work for the elimination of cracks and fissures facade.
The air chamber should be continuous and at least 5 cm thick.
Consider thermal bridges of the facade, both occurring in the contour of the recesses, as those occurring in meetings between the front cover and the front of the slab.
Projected polyurethane foam insulation is the quintessential used in the rehabilitation of facades injected chambers. The correct implementation of facade insulation injected cameras requires injected polyurethane layer has at least a minimum thickness of 30 mm and a minimum density of 12 kg FACADE WITH INJECTION CAMERAS m3 and may be made both on the inside as on the outside of the facade.
System facade insulation injected chambers is recommended when other possibilities have been ruled facade isolation from the outside, and not want to miss interior space of housing. To ensure an outcome of facade insulation injected optimal cameras if you opt for it, should ensure that injections of polyurethane made through spaced holes 50 cm apart at most, starting with the bottom (stuffing chamber bottom to top), and are not located in the same line.
The faade insulation injection chambers in addition to providing an insulating layer of the facade also provides rigidity to the facade. It requires special care in its execution and, despite providing sealing of the facade can not guarantee the waterproofing of the same or the overall treatment of thermal bridges.
