Structural ventilation keeps buildings healthy, as it removes moisture
from within spaces such as roof structures or crawl spaces.
Ensuring proper ventilation of roof structures prevents condensation, water damage and further fungal and microbic growth inside these constructions. Renovating the damage caused by damp or mould can be very costly, and it is therefore important to pay attention to the adequate ventilation of roof structures – both in small and large buildings.
If a roof is not ventilated properly, moist air rising through the building can condense and cause moisture in the thermal insulation of the roof. During winter, this moisture can freeze and cause the thermal insulation to lose its insulating properties, which in turn can result in a significant rise in heating costs. Excessive moisture also promotes the growth of fungi, moulds and micro-organisms, which destroy the structures within a building.
VILPE Alipai Underpressure air vents allow the roof to breathe ventilating the roof structures and ensuring the efficient removal of moisture. An Underpressure air vent is also suitable for ventilating a cold attic space. Their operation is based on the air pressure difference caused by the wind. Alipai low pressure air vents are available for the low-pitched, inclined and ridge sections of low-pitched roofs.
The KTV roof vent can be used for ventilating roof structures and attic spaces, as well as for ventilating sewer pipes. The KTV roof vent can be selected from 10 different models according to the roofing material being used.
Humidity which moves from the surrounding environment into the underfloor spaces must be carefully removed to prevent both health hazards and structural damage.
The Ross ventilation pole is an elegant choice for the ventilation of underfloor spaces as well as for prevention of moisture damage in the base floor. The Ross ventilation pole can be used as an air inlet for a basement sauna, fireplace or mechanical ventilation system, and is also suitable as a replacement or exhaust air terminal in more sopihisticated systems. In addition, Ross ventilation poles can be used together with a radon fan Eco110 to remove radon gas from subfloor spaces.” Watch this video to learn how easy the installation of the Ross ventilation pole is (subtitles in English available).
