Eco-Closer

The ARC Eco-Closer is easily installed, either as the brick and block work progresses, or in to pre-formed openings. Simply cut the jamb profile to the height of the window or door opening plus 75mm to allow the bottom edges to drop into the cavity below the sill. Once the jamb sections are installed, measure the required width for the sill section and cut a length to butt tightly to the jamb sections. If a longer length than 2.4m is required, see jointing method to the right.

Option 1 (First Fix)

As above and build in the jamb sections as the brickwork progresses using ARC Brick Ties* (1 every 225mm). Ties are not required on the sill section, simply hold in place with an adhesive or nail to block. ARC Brick Ties are optional and are sold separately.

Option 2 (Second Fix)

Cut sections to required size as above and simply push fit once the openings are formed. Sections can be secured by nailing to block or using a suitable adhesive.

» No gaps should exist either between the cavity closer and construction, or between jointed sections

» The cavity closer must fill the cavity between brick and block, with cavity insulation cut back

» The PVC up-stand should be fitted against the external leaf to deflect any moisture penetration through the brick

» A plasterboard sill should be mechanically fitted over the cavity closer

» Care should be taken when handling the product to ensure that the mineral wool isn’t damaged.
