Product Description

Description

The GridFusor™ is specially designed as a replacement for ceiling tiles in a standard drop ceiling grid. Two GridFusors™ will easily fit into a standard 2′ x 4′ grid opening. The GridFusor™ is made from EPS (expanded polystyrene) so it’s light enough easily mountable on walls, ceilings, etc. without the use of damaging adhesives or massive mounting holes while still providing excellent diffusion characteristics.

Specifications

• Thirteen-root QRD diffusor design
• Easily paintable (water-based paint only). Painting will have no impact on diffusion characteristics.
• Square shape allows for easy orientation changes to scatter in multiple dimensions.
• Dimensions: 23.75″ x 23.75″ x 6” thick
• Easy to install using small nails or double-sided tape

Materials

Camira Cara Fabrics

GIK is excited to use the Camira Cara fabric line standard in all our products. The Camira fabric will look familiar to fans of Guilford of Maine fabrics, similar to their FR701 line but with different color options. With a richer aesthetic and tactile feel and wider range of available colors compared to our previous standard offerings, Camira Cara allows every product to look as good as it performs.

Sustainability

GIK Acoustics has long prioritized sustainability as a guiding principle. We carefully select materials that balance acoustic performance with environmental responsibility, sourcing from suppliers who share our commitment to reducing waste and carbon impact. Our products use durable, recyclable components that minimize landfill waste while maintaining the highest acoustic standards.

Health & Safety

Health and safety are built into every GIK product. All materials—including fabrics, cores, and wood elements—are formaldehyde-free, and independently tested for indoor air quality. This ensures our treatments are safe for studios, homes, schools, and offices alike. We believe superior acoustics should never come at the expense of well-being, which is why our products are made with clean, non-toxic materials that protect both the people who use them and the spaces where they’re installed.

Care Instructions

Camira Cara Fabric

Vacuum regularly. Wipe with a damp cloth using soap and water or use proprietary upholstery shampoo. For deeper cleaning use bleach or alcohol.

Veneer Finishes

Clean with a soft cloth or soft brush, lightly dampened with lukewarm PH-neutral, soapy water. Do not use solvents or chemical cleaners, but cleaning can be done with alcohol-based cleaners. Finally, wipe with a damp cloth afterward.

A Lightweight Ceiling Diffusion Solution

Ceilings, especially in taller rooms, are excellent places for diffusion. If, however, you have a drop tile ceiling, it’s difficult to hang anything from it. Drop ceilings can also provide a bit too much upper-, mid- and high-frequency absorption. We have a solution for you: the GIK Acoustics GridFusor©.

Mirror-Imaged 13 Root Diffusers

Incorporating a mirror-imaged pair of 13-root diffusors, the GridFusor© provides excellent diffusion from 600 Hz to 5,000 Hz and additional scattering below and above the diffusion range. The GridFusor© is light enough that no additional support is required for your existing ceiling grid and it’s light enough that insulation above can still provide broadband bass control.

The Antidote to Dead Ceilings

If your room is a bit too dry due to carpeted floors and acoustic tile ceilings, the GridFusor© is a perfect solution. Stop having your hands tied when it comes to dealing with room acoustics where a drop tile ceiling is required.

Although the GridFusor© is designed to work in a drop ceiling situation, it can also be used other places in your room as required. It is easily mounted with impaling clips.

Lightweight, Unfinished, Paintable

The Gridfusors are made from unfinished EPS foam, so they are lightweight. They can be painted (with non-oil-based paint only) to match any decor.

FAQ

What is the GridFusor used for?

The GridFusor is a lightweight, molded diffusor that scatters sound to reduce flutter echoes and create a more natural sense of space. It’s an affordable way to add diffusion without adding absorption that deadens the room.

Where should I install the GridFusor?

The GridFusor is designed to fit perfectly into standard drop ceiling grids, making installation quick and seamless. They can also be mounted to walls using impaling clips, brad nails, or screws, giving you flexibility to place them wherever reflections need to be scattered while keeping energy in the room.

How does the GridFusor differ from wood diffusors like the Q7D or Q11D?

While the Q7D and Q11D are solid wood quadratic diffusors with deeper frequency range coverage, the GridFusor is made from lightweight molded EPS foam. It’s less expensive, lighter, easier to install in ceilings, and still very effective in the mid and high frequencies.

Can I mix GridFusors with absorptive panels?

Yes. In fact, combining GridFusors with broadband absorbers or bass traps is one of the best strategies for achieving a balanced acoustic environment. The absorbers handle decay control, while the GridFusors keep the room lively and open without being harsh.

    Works as advertised. Seems kind of expensive for styrofoam. Easy to install.

    GridFusor - but not as we know it.

    Although this GIK Acoustic product is best used 'as is' on any remaining larger surface areas where diffusion or dispersion is desired - I actually go to the effort of fully integrating it into a design aesthetic.

    For example see picture below where I have sliced several GridFusors (previous product name VersiFusor) into 10cm wide strips and then applied these strips in-between gaps of GIK Acoustics Monster Bass traps placed on ceiling. The view is of the ceiling (looking at first reflection point) is taken from the listening position in dedicated HiFi/media room.
