Thermal Washer with Cap is a molded tube washer with a 2-9/16 diameter (65mm) face for holding back insulation.
The washer can be used with almost any screw up to #1/4 gauge and with a head size up to 5/8 making it incredibly versatile. Incorporated into the polyamide molding is a cap that neatly flips shut, hiding the screw and virtually eliminating any thermal bridging without the inconvenience of installing a second part.
If necessary, it is then possible to render over the washer without any worry of an uneven surface. The washer is conveniently boxed in 100s for easy transportation and ease of application on site.
