Acara Concepts Ltd – Natural & Sustainable Thermal and Acoustic Insulation

Specialist Insulation Solutions for Construction and Renovation
Acara Concepts Ltd is a specialist distributor of natural and sustainable thermal and acoustic insulation materials. Established in 2007, the company supplies products from European manufacturers to architects, specifiers, contractors, installers, developers and homeowners throughout the UK and Ireland.

Naturheld Wood Fibre Insulation
Naturheld wood fibre insulation provides thermal and acoustic insulation for walls, roofs, attic floors and suspended timber floors. The range includes rigid boards and flexible batts for different construction systems. Wood fibre insulation is vapour-open, hygroscopic and capillary-active, helping manage moisture when correctly specified within an appropriate building design. It also provides thermal mass and can contribute to acoustic comfort.

Naturheld 140, 180 and 220 are water-resistant tongue-and-groove boards for internal and external applications, including wall insulation, roof sarking and timber-frame construction. They can be finished with suitable lime plaster or render or ventilated cladding. Naturheld 110 boards are suited to CLT structures or for between studs, rafters and joists.
Naturheld Flex is a flexible wood fibre batt for installation between studs, joists and rafters.

Roof, Wall and Floor Insulation
Acara Concepts supplies Naturheld wood fibre solutions for roofs, solid masonry walls, timber-frame and CLT construction, loft floors and suspended timber floors. Systems can be specified for internal or external insulation, with suitable breathable finishes or ventilated cladding.
Naturheld Flex can be used between suspended timber floor joists where the construction and ventilation arrangements are suitable. For solid ground floors, the company supplies Glapor recycled foam glass insulation with Limecrete screed for vapour-open floor build-ups.

PhoneStar Acoustic Insulation
Acara Concepts distributes PhoneStar sound insulation panels throughout the UK and Ireland. Made from sand and structural cardboard, PhoneStar panels are designed to effectively reduce sound transmission through walls, floors and ceilings.
The product range has European Technical Assessment ETA 20/0371. Published test data for 15mm PhoneStar TRI boards includes airborne sound insulation of 38 (-5) dB Rw (Ctr) and impact sound reduction of 22 dB ΔLw for the boards tested on their own. Actual overall performance depends on the complete construction build-up, installation and surrounding structure.

LIGNO® Timber Acoustic Panels
Acara Concepts supplies LIGNO® slatted wooden acoustic panels for interiors requiring sound absorption and natural timber finishes. Available profiles, timber species and finishes suit residential and commercial interiors, offices, education and hospitality projects. Fire classifications depend on the selected product and finish.
