Brits Nonwoven

Isotherm and its insulation derivatives are manufactured to the highest standards by Atlantis-based Brits Nonwoven.

The product range consists of lightweight, compressible but resilient insulation material manufactured from thermally–bonded polyester. Once correctly installed, no maintenance is required. Unlike traditional glass-fibre materials, the Isotherm range is safe to handle and can be installed without protective clothing, gloves or masks.

Eco-friendly, Isotherm is manufactured using polymer from recycled PET bottles and is itself 100% recyclable.

Isotherm - Ceiling insulation
Isotherm reduces the passage of solar heat into a structure during summer and saves energy in winter by reducing heat loss through the roof.

Non-toxic and user-friendly, Isotherm does not sustain vermin and is resistant to fungi and bacteria. Aside from its thermal and acoustic insulation properties, it is easy to handle and rapid to install. It is manufactured in blanket form thus it can be cut to fit snugly between ceiling beams and wrap around hot water plumbing.

Isofoil - Composite insulation 
Isofoil is designed for the factory or warehouse where there is no ceiling, the agriculture or poultry farming industries. The outer jacket is made from aluminium foil or polyethylene. Both facilitate condensation control under metal deck, fibrous cement and tile roofs.

Acoustisorb - Acoustic insulation
Acoustisorb is ideal for use in walls and partitions needing acoustic (and thermal) insulation.

Isotherm and Acoustisorb derivatives
A variety of Isotherm and Acoustisorb derivatives have been developed, including duct lagging, geyser blankets and flexible combinations of thermal and acoustic insulation materials.

Flammability
Isotherm is non-flammable, thus fire-retardant chemicals are not required.
