Yes, we can supply the closure cut to the final aperture shape. Also available in strip form for linear gaps or in sheet form for site cutting.
Generally, sizes in the region of 50mm to 200mm wide are commonplace for linear applications. Infills to the underside of profiled decks are usually cut to fit the cross-section of the aperture.
No specialist equipment is required. AVCs are semi-flexible, allowing deformation for ease of installation; linear strips are usually compression fitted into place. The SSPL technical team can offer guidance on additional fixings to secure large deflections or voids.
Siderise AVCs do not have a tested fire resistance rating; they are supplied as an acoustic only void closure. Where an application has a fire stop requirement, AVCs can be fitted in pairs either side of the fire stop to greatly enhance the SRI. See Siderise TW range for when a fire resistance performance is also required.
