PRODUCT USE
Primarily intended for use as an economical weatherproofing membrane for sheds, non-habitable garden buildings and animal shelters. Life expectancy of the product varies greatly due to exposure to weather elements and also quality of installation.
COMPOSITION AND MANUFACTURE
The base carrier consists of a glass fibre matting which is coated both sides in modified bitumen. The coated material is finished with a fine mineral granule on one side to aid UV protection and sand on the reverse. The membrane is cut to roll length, wrapped and labelled according to specification
INSTALLATION
Shed felt can be used as a single layer, but for best performance install over a suitable underlay which should be nailed onto the substrate. The Shed felt should then be installed using clout nails and felt adhesive to seal the laps (75mm min).
Start from the eaves (lengthwise), work upwards and finish with overlaying the ridge.When installed as a single layer the minimum pitch of the roof should be greater than 20 degrees. Membranes coated with oxidised bitumen remain flexible above 5°c. During colder periods care must be taken when handling and installing as to prevent cracking of the bitumen
and damaging the membrane. It is not recommended to use below 5°c.
STORAGE & HANDLING
Do not drag rolls across rough surfaces, they should be lifted. They should be stood on their end on a dry surface. If using pallets do not stack more than 2 high. Avoid mechanical damage and wet storage conditions. During colder periods it is recommended that rolls are stored at a temperature above 10°c for 24 hours prior to use, and not unrolled, folded or used
in temperatures below 5°c.
