ARC Eco-Closer closes the cavity around window and door openings in masonry walls, providing up to 60
minutes fire integrity. The rigid PVCu profile is insulated with non-combustible rockfibre mineral wool which
provides fire and thermal properties.

Installation

The person installing the ARC Eco-Closer should
first familiar themselves with this datasheet,
ensuring the correct product is being fitted into the
cavity.
The ARC Eco-Closer is easily installed, either as
the brick and block work progresses, or in to preformed 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.

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.

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.

Jointing Method
Where a longer length than the supplied 2.4m is required, the following jointing method should be used. Using an appropriate saw, remove 150mm of the plastic profile only, then push the exposed insulation into the next length
of plastic profile.
