Method for attach fiberglass to MDF walls

[JC Fardo]

Hi

I have a TL building in progress and its project indicates linning the line walls with fiberglass roof mat. Our local stores sells 15mm ( 5/8") yellow resin hardened FG roof mat sheets with decorative PVC skin. From Saint-Gobain with commercial brand "Forrovid"

What is the best usual method you DIY member use to stick the roof mat to MDF

Hot melt, hot melt in dots, contact glue, PVA glue?

Peel off the PVC?

In advance thanks form comments and assistance

Are you sure you need the fiberglass panels and not just loose fiberglass insulation ? If it's really the panels you are supposed to use, you'd probably need to use an epoxy or fiberglass resin and use weight to ensure the entire panel maintains good contact while the resin cures. Spot gluing or even just having a small air pocket could result in noise from vibrations that would be very difficult to eliminate. Adding fiberglass panels is the kind of thing done before assembly, so it's probably insulation that you need, not the "resin hardened" panels.

Hi

Thanks for comments

That´s the pic from an original Bob MLTL box posted at Madisound board. I had to take my conclusions from that.

I think you´re right WRT epoxy glue and preassure to avoid air gaps

Those are panels but they are soft enough to cut with a razor knife. If that's what you have, I'd just peel off the plastic or foil and glue them in with contact (rubber) cement. I thought you were talking about some stiff strong fiberglass panels.

Around here those compressed glass wool panels are used in drop ceilings. Yup, peel off the decorative plastic film on one side and discard, and just use spray contact cement to boh surfaces as per instructions on the can. I have used this type of ceiling panel to line the walls of one of my very successful transmission lines.

Wear a respirator with that spray adhesive! It is IMO one of the most deadly things you can get your hands on without a special permit.

Drop ceiling panel. Yes, that´s the correct words I´was looking for.

Around here there´s a new water based contact glue, to brush in, not spray. I´ll try here and for veneering too.

RCA, what drivers and TL geometry is yours?

More (successful, I hope) results to come

Sorry, cannot talk tech about my proposed commercial offerings. Suffice it to say the line design is unconventional. BTW this is not the Ultor-XTM speaker shown in my avatar.
