Solutions for Fire
ARC Eco-Closer
The ARC Fire Rated Eco-Closer is a rigid PVCu profile, with flexible weatherseal, insulated with non-combustible rockfibre insulation. ARC Eco-Closer has 1 hour fire integrity, tested at Warrington Fire Research. Preferred by specifiers and ideal for all types of building work including major contracts.
Four in one rockfibre insulation, providing a fire, thermal and acoustic solution as well as environmental benefits (zero ODP and GWP).
Complies with the 2010 Part L Building Regulations. Prevents cold bridging, eliminating moisture, mould and staining around windows and doors.

ARC Fire Rated Insulated DPC / Cavity Closer
The ARC Rockfibre Insulated DPC ins an insulated DPC which has been developed to close masonry cavities for thermal acoustic and fire applications. The primary reason for fitting the ARC Insulated DPC is to close off cavities around windows and doors preventing cold bridging. Can easily be installed as the brick and block work progresses where a traditional block return is used. Also available with a polyethylene insulation.
- 4 hours fire integrity - Warrington Fire Research test
- Easy to install
- Prevents cold bridging
- Exceeds the minimum requirement for Part L 2010 provided the window is set back 30mm from the inner face of the outer brickwork and thermally efficient materials are used in the construction
- Manufactured to NCBC standard

ARC Rockfibre Lamella Thermal and Acoustic Plasterboards
Designed to offer both thermal and acoustic insulation for internal walls, helping to improve upon statutory requirements. ARC Rockfibre Lamella Plasterboards are suitable for both refurbishment and new build projects in the domestic and commerical markets where increased thermal and acoustic performance is required. Rigid rockfibre slabs are cut into strips and turned through 90 degrees so that the fibres lie at right angles to the plasterboard. This gives increased resistance to compression of a slab of the same density.
ARC's Lamella Plasterboards are manufactured using rockfibre mineral wool which conforms to BS EN 13162: 2001 Thermal Insulation products for buildings, factory made mineral wool products specificiation, and achieves a fire classification of Euroclass A1 as defined in BS EN 13501-1.
Also available with a standard rigid rockfibre mineral wool slab insulation.
Various sizes and thicknesses available on request.
ARC Lamella Plasterboard Laminate:
Plasterboard length 2400 x 1200mm wide x 12.5mm thick.
Plasterboard conductivity 0.25W/mk
ARC Thermal and Acoustic Lamella Floor Boards
Designed to provide both thermal and acoustic insulation for both ground and intermediate floors, in either new build or refurbishment work. ARC Thermal and Acoustic Lamella Floor Boards consist of high density Rockfibre mineral wool lamella strips bonded on to tongue and grooved moisture-resistant chipboard.
- Excellent thermal and acoustic insulation
- CFC and HCFC free
- Suitable for all constructions
- Will accomodate pipe runs and minor imperfections in sub floor
- Easy to lay
- Suitable for new build and refurbishment work
The ARC Lamella Floor Board works on the 'floating floor' principle to isolate and absorb impact and airbourne sound. Rigid Rockfibre slabs are cut into strips and turned through 90 degrees so that the fibres lie at right angles to the chipboard. This gives increased resistance to compression of a slab of the same density, whilst remaining resilient to take up imperfections in the sub floor.
Available with either 18 or 22mm chipboard bonded to insulation with a thickness ranging from 15 to 100mm.
ARC Lamella Boards:
Chipboard length 2400mm x 600mm wide x 18mm thick
Chipboard conductivity 0.14 W/mk
Insulation: Lamella Rockwool Conductivity 0.044 W/mk, lamella rockfibre insulation supplied to the required thickness standard thickness 25 - 100mm)
