Flexi Frame.

Use Flexi Frame on ceilings and walls to eliminate unnecessary noise, ensure optimal sound absorption and to add an extra design dimension to your rooms. With beautiful wood panels and a sound-absorbing core consisting of insulation, you invite nature in and create tranquillity.


I-Wood Denmark® Flexi Frame is produced according to the customer’s specific dimensions. Below are several examples showing the sizes and the different dimensions. To reduce waste and fully use the panels, you should aim to keep the module height below 1400 mm. This allows you to create two pieces from one panel.

Examples, dimensions:
(W x H) (D: 40mm)

All wood panels from I-Wood Denmark® are produced with an A-veneer, to ensure the best quality in your room.

Our acoustic panels are available in several types, including plain MDF, moisture resistant MDF and fire-retardant MDF. Selected variants are available with both black and light coloured MDF cores.

Plain MDF is used indoors for classic ceiling and wall panels. Moisture-resistant MDF is treated with special oil, so your panels can resist rot and mould and thus can be used outdoors as under-panelling, in overhangs, covered terraces or carport ceilings. May not be used on vertical surfaces that are directly exposed to water.

Fire-retardant MDF has a B-s1, d0 approval as raw board. Additionally, we offer surface treatment using a flame-retardant polyurethane varnish.

Panels from I-Wood Denmark® have sound-absorbing properties, they ensure improved acoustics and reduce excessive noise. Flexi Wall and Flexi Frame both have 22 mm of insulation built-in, which is a sound absorbing material. The two products both have a diffusing and absorbing effect and will improve the reverberation and acoustics in the room.

Acoustics and well-being are important fields and for this reason we have collaborated with Force Technology and had them perform a range of accredited acoustic tests. Read more about what good acoustics are and find more specific examples of this. You are also welcome contact us with any technical questions.


For installing I-Wood Denmark® Flexi Frame, we recommend loosening the felt from the upper left and right corners, respectively. Loosen the felt approx. 15-20 cm down to make room for fastening. Fasten Flexi Frame at the desired height by inserting a screw through the frame between two wood strips. This is done on both the left and right corners. The type of surface will determine whether this should be done before installation.


The felt is produced from 100% recyclable plastic, a large proportion of which is collected from the world's oceans. In addition, all our wood is CE-approved and purchased from FSC-certified suppliers. Thus helping to ensure sustainable forestry, with the focus on abundant plant life, wildlife and working conditions.
