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, thermal and acoustic properties.

Manufactured using rockfibre mineral wool that has a thermal conductivity of 0.037W/mK and achieves a fire classification of Euroclass A1 as defined in BS EN 13501-1, and conforms to BS EN 13162 and EN16001 Energy Management Systems.

ARC Eco-Closer will significantly reduce the risk of cold bridging around window and door openings when fitted in accordance with the manufacturer’s recommendations.

FEATURES AND BENEFITS

• Up to 60 minutes fire integrity
• Prevents cold bridging
• Integral DPC helps eliminate moisture, mould and staining around windows & doors
• Easy to install – no mechanical fixings required
• 2.4m lengths

INSTALLATION

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 please refer to ‘Jointing Method’ below.

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) THIS IS THE MOST COMMON METHOD OF INSTALLATION:
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

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.
