SNOWHITE - SWMX
Thermal Insulation of Tiled Roofs, Metal Roofs and Hollow External Walls
Cat. No. SWMX
Snowhite – SWMX is an insulation system consisting of a multi-layer sheet combining a reflexive radiation barrier with an insulation layer of, pure and flexible polyester fibers. The radiation barrier is made of a reinforced aluminum foil with a low emissivity level, approximately 3%. The reflective side (the shiny one) of the barrier faces outside.
Snowhite – SWMX is used for thermal insulation of tiled roofs, low-weight roofs, hollow external walls in residence, industrial, agriculture buildings and for insulating air-condition ducts.

Using Manner
General:
Snowhite – SWMX insulation cutting method: by means of simple (long) cloth scissors.
The insulation is attached to the beams by means of a pins-gun. The height of the pins' legs: 10-12 mm.
To cover overlaps (usually unnecessary) use dedicated aluminum masking tape. Apply masking tape in the same manner at slopes' junctions (corners) for attachments that are not to beams.
The Snowhite – SWMX is suitable for insulating tile roofs subject to I.S. 921.
Installation under tiles on an existing roof:
Stretching the Snowhite – SWM perpendicularly to the roof's slanted beams.
- Stretch the Snowhite – SWM horizontally, perpendicular to the beams and attach by means of a pins-gun to beams' bottom.
- It is recommended to create 5 cm. overlaps between every two sheets, with the lower insulation overlapping the higher one from beneath.
