Owens Corning 703 series acoustic insulation (also called rigid fiberglass) is the #1 global material for in-frame absorption as well as building acoustic panels and bass traps. It’s used by top brands like Nankarrow, Acoustimac, Auralex, Acoustical Surfaces, Real Traps, GIK Acoustics, etc. and is also recommended by top global acoustic consultants. It is stiff enough to be easily wrapped without requiring to be framed using an edge hardener yet it is very easy to cut into shape. It is ideal for DIY acoustic panels or fiberglass acoustic panels.
Combine two layers to make broadband panels for your studio or home theatre. Place one acoustic panel in every reflection point in your room. Typically the critical reflection points are the 2 spots to the side of each speaker, the ceiling directly above the speakers and the opposite wall to the speakers (behind listening area). We would also recommend that you place more acoustic panels every 2 feet thereafter to get the best absorption possible.
Owens Corning® Types 703 & 705 700 Series® Fiberglass Insulation™ Boards are made of inorganic glass fibers with a thermosetting resin binder and formed into rigid boards.
Owens Corning 703 Fiberglass Acoustical Board is the preferred product for use as the core insulation for acoustical wall and ceiling panels. The reasons for the popularity of the 703 Fiberglass panels mainly has to due with the panels ability to absorb both Mid and High range frequencies while being lightweight, rigid, and economically priced. Owens Corning 703 Fiberglass Acoustical Board is made of 48kg/m3 density fiberglass which allows the panels to be both lightweight and rigid. 2″ 703 Fiberglass Board is very good at absorbing both Mid and High range sound frequencies which makes it the ideal product for Acoustical wall / ceiling panels. When you double them up (4″), they become effective upto 100Hz. At three layers (6″) they can absorb down to 70Hz. So 703 Fiberglass panels should be stacked to create thicker panels to better absorb low frequencies in Bass Trap applications.
2″ Owens Corning 703 Fiberglass panels are usually inserted into a 2ft x 4ft frame and then wrapped with acoustical transparent fabric and fastened to walls/ceilings with panel hardware. The 2″ 703 panels can also be used to make frameless acoustical panels. Coat the perimeter edges and 4 corners of the fiberglass with an edge hardener, wrap the fabric directly over the fiberglass panel.

Acoustic Performance in 1/3 Octave Bands
OC Type 703 can be easily cut with a knife and fit neatly into irregularly shaped areas. Fasteners shall be located not less than 3″ (75mm) from each edge or corner of the board. Pin spacing along the equipment should be no greater than 12″ (300mm) on centers. Additional pins or clips may be required to hold the insulation tightly against the surface. Weld pin lengths must be selected for tight fit but avoid “oil-canning.”
For Vertical Applications
Type 703 can be installed between furring strips, hat channels and Z-shaped furring where a finish will be applied.
For exposed applications
The product can be impaled on impaling pins or adhered with adhesive.
For Horizontal Applications
Type 703 can be installed on horizontal surfaces by using impaling pins.
On Masonry Construction Type 703 and Type 705 can be installed on the interior face with Nankarrow ProPin self adhesive impaling pins, or by using appropriate adhesives. Lengths should be selected for tight fit. Protect pin tips where subject to contact. Pins should be located 3″-8″ from the edge(s) of the board.
