Window & Door

Window & Door, thanks to its dimensional stability and the mechanical properties of the cured product, is ideal for bonding, fixing, insulating, soundproofing, sealing and filling. The use of a special blend of propellants in the formulation allows it to be used even at ambient temperatures as low as -10 °C. Furthermore, the structure of uniform, predominantly closed cells gives the cured foam thermal insulation and soundproofing properties (see test reports from the Masini Institute 1016-2008 dated 31 March 2008 and IFT 16732059 dated 22 September 2006), in accordance with CEI 64-8, Article 511.1. It adheres firmly to wood, concrete, brick, asbestos cement, metal, glass and plastic, with the exception of polyethylene, Teflon and silicone. The cured foam can be cut, drilled, sanded, painted and plastered. The product is certified as EC 1 Plus by the GEV body in terms of very low emissions of volatile organic compounds.

Instructions for use

1. Substrates must be free from oil, grease and dust. Moisten the surface before application to ensure the fresh foam has the necessary moisture to form a uniform cellular structure.
2. Remove the protective cap from the nozzle and screw it onto the appropriate spray gun (such as the T2000 or T500 models from Torggler Srl) or, in the case of the manual version, after removing the cap from the cylinder, screw the nozzle with the supplied extension onto the valve.
3. Shake the cylinder for at least 15 seconds before use and repeat this step after any breaks in work.
4. Turn the cylinder upside down so that the valve is facing downwards, point the gun barrel/extension tube in the desired direction and press the dispenser with your fingers. The degree to which the cavities are filled must take into account the foam’s post-expansion. In the event of low ambient humidity, moisten the beads immediately after extrusion.
5. The foam will be fully cured approximately one hour after application. After this time, any excess foam can be cut away with a cutter or smoothed with sandpaper.
6. If you do not use the entire contents of a cylinder, return it to an upright position and press the nozzle for a few moments. The escaping gas will clean the valve and the gun/nozzle extension.

Cleaning
Traces of uncured foam, for example on clothing, tools, etc., can be cleaned with polyurethane foam solvent. Cured foam can only be removed mechanically (by scraping or sanding).

Notes
The foam output is highly dependent on the temperatures of the cylinder and the substrate. At low temperatures, both the discharge pressure of the fresh material from the valve and the yield of cured foam are reduced. To achieve a good yield, it is recommended that the cylinder be stored at a temperature of approx. +20 °C and in any case never below +5 °C. At higher temperatures, it may be difficult to dispense the product correctly, as the increased pressure inside the cylinder makes it harder to control the flow of material from the valve.

Storage

Store in a cool place in an upright position. Take great care to avoid storing the product horizontally, as this causes deposits to form rapidly beneath the valve, which will irreversibly impair the extrusion of the foam. Window & Door has a shelf life of at least 18 months when stored upright, in a cool place (at temperatures below 25 °C), in a dry place and in its original, unopened packaging. Observe the expiry date indicated on the cylinder.

Warnings

Substrates and objects that are completely saturated with water prevent the foam from adhering.
The Window & Door can is a pressurised container. Protect from direct sunlight and do not expose to temperatures exceeding 50 °C. Do not pierce or burn, even after use. Do not spray onto a flame or any incandescent object. Keep away from all sources of ignition, flames and sparks. Do not smoke. Do not breathe in the aerosols. Keep out of the reach of children. This product contains highly flammable components; therefore, use it only in well-ventilated areas. Particularly when using several cans in the same location, there is a risk of explosive air/propellant gas mixtures forming. Contains 4,4'-diphenylmethane diisocyanate (EEC No. 615-005-00-9). Harmful if inhaled. Irritating to the eyes, respiratory tract and skin. May cause sensitisation by inhalation and skin contact. In case of contact with the eyes, rinse immediately with plenty of water and seek medical advice. In case of skin contact, wash immediately and thoroughly with soap and water. Wear suitable protective clothing and gloves. In case of inadequate ventilation, use a suitable respirator. In the event of an accident or if you feel unwell, seek medical advice immediately (if possible, show the label to the doctor).
