Novia AirSeal 310 FR Sealant
Fire rated sealant to improve airtightness in vapour control applications
Product Overview
Novia® AirSeal 310 FR is a halogen free, polymer emulsion-based cartridge sealant. It is easily applied and dries to a flexible and smooth surfaced finish which provides movement capability in fire rated linear joint and penetration seals. It is readily over paintable. It has excellent adhesion to a wide range of substrates and will not harden or crack with age.
Novia® AirSeal 310 FR should be used in all applications where additional sealing is required, for example internal corners, floor sections or window reveals. Novia® AirSeal 310 FR should be used in addition to Novia’s other AVCL installation tapes: Novia® Double-Sided Butyl Tape and single-sided Novia® Aluminium Foil Tape or Novia® Metallised BOPP Tape.
Novia AirSeal 310 FR forms a fire and smoke seal in joints up to 35mm wide without slumping. It is ideal for sealing joints such as:
- Air and Vapour Control Membranes
- In and around internal partitions where flexibility may be required
- Linear gap seals. Vertical or horizontal at head or foot of wall.
Use in conjunction with VC4000 Fire Rated Air and Vapour Control Layer.

Installation Tips
To achieve a high-quality joint, ensure surfaces are dry and free of all dirt, oil, and loose material, using a wire brush if necessary. Non porous surfaces should be degreased using a suitable degreasing agent. Highly porous surfaces should be sealed with a suitable primer. For a cleaner finish, apply masking tape to each side of joint and gun sealant firmly into joint, smoothing off with a wetted spatula. Masking tape should be removed within 10 minutes of application.
Due to the wide variety of construction materials available, it may be necessary to test the suitability of the surfaces and substrates to be sealed prior to use. Novia® AirSeal 310 FR is not suitable for use as the load-bearing element of a system, so the use of mechanical fastenings is always required. Use galvanised or stainless fixings that will be permanent, and are strong enough to support the weight of the installation.
A sealant cartridge gun is required to be able to use this product effectively.
