Skate and perforated ventilation tapes prolong life and give the cottage a finished look. The tape covers all the ventilation slots of the roof, providing air exchange in the under-roof space and preventing the penetration of pests into it. Read about what ventilation tape is and how to use it.
Types and functions of ventilation tape
Depending on the purpose, the ventilation tape is:
- ridge;
- perforated (overhang aero element).
Insulated pitched roofs must be ventilated. In the absence of air exchange in the roofing cake, moisture accumulates, destroying the wooden supporting frame and roofing material. Insulating properties of insulation are deteriorating.
Without ventilation, condensation is constantly collecting under the roof. In large quantities, it seeps through the ceiling, causes mold and spoils the appearance of living quarters.
To prevent this process, it is necessary to ensure the free movement of air in the roofing cake. Air enters here from under the eaves overhang (eaves) and exits through the ridge (ridge products). A counter beam is fixed between the waterproofing and the roofing material, creating a gap for the movement of air. In such conditions, wooden roof structures will last longer than with constant exposure to moisture and fungus.
Benefits of Using Ventilation Tape
Advantages of using ventilation tape for roofing:
- high breathability;
- decorativeness;
- protection against rodents, insects and birds.
It should not be confused with a sealing self-adhesive tape for ventilation, which is designed to seal profiles of frames, pipelines and insulation joints of air ducts.
Skate ventilation tape
The ridge ventilation tape for the roof protects the ridge (rib) of the roof from the ingress of precipitation. At the same time, it passes air and steam from below, from the roofing cake, preventing wetting and decay of the roofing material and the rafter system.
A sealing tape for ventilation is installed on the roof edge, a skate is mounted on top of it.
The ridge ventilating and sealing tapes are made of aluminum foil, polyethylene, polypropylene textile, the layers are glued together with butyl glue, and aluminum spraying is used as a protective layer. The ventilation tape is treated with compounds that protect against ultraviolet radiation. The ridge ventilation tape has a ribbed structure, due to which it is stretched by 20 - 40%. The warranty period of the tape is from 10 years.
Tapes are produced in widths from 240 to 390 mm in rolls.
The breathability of the ridge ventilation tape is 270 - 300 grams per square meter. meter.
The ventilation tape for the roof is designed for operation at a temperature of -30 ... + 80 degrees Celsius.
Moisture permeability - 3 - 6 grams per square meter. meter per day.
A roof ventilation tape is installed at an air temperature of +5 degrees.
Perforated Direct Ventilation Tape
The purpose of the overhang ventilation tape is to cover the eaves overhangs from birds and insects without disturbing the air exchange in the under-roof space and the appearance of the building. In addition, perforated ventilation tape is used to reinforce the rigidity of some roof structures.
Punched tape for ventilation is made from:
- perforated steel;
- perforated aluminum;
- polyvinyl chloride (PVC).
Material thickness 0.55 - 1 mm.Holes are made in different shapes and sizes of 3 - 8 mm. The width of the tape is 120 - 250 mm, the length of one piece is 10 - 30 m in the bays. Punched tape for ventilation with smooth or wavy edges is made.
Fastened to the structure of the tape for the ventilation overhang with screws or nails. No additional tie-in is required, therefore the rigidity of the structure is ensured. All materials are resistant to moisture and ultraviolet radiation. During installation and operation in accordance with the standards, the service life of the ventilation tape for eaves overhang from 10 years.
PVC ventilation tape
PVC ventilation tape has a longer shelf life and a variety of colors:
- white
- brown
- black
- terracotta;
- red.
Such a palette allows you to choose a ventilation tape made of plastic (PVC) for almost any color of roofing. The width of the PVC tape for ventilation is 10 cm. A ventilation tape is made of PVC (plastic) with 5 m rolls.
