Twiga Eco Insul

Twiga Eco Insul (TEI), a new generation glass wool insulation introduced by U.P.Twiga Fiberglass Limited. It’s a high performing insulation solution for thermal and acoustic applications. Eco Insul is soft to skin, odourless and formaldehyde-free. The product is completely fire safe (non-combustible). It fulfils all the requirements of National Building Code, 2016 - Part 4: ‘fire and life safety’ and Part 8: ‘Building Services’ –Thermal insulation. The insulation meets all mandatory and optional requirements of IS 8183, too. It is available in flexible blanket/roll form and semi-rigid or rigid board form. Several factory-applied laminations or facing options are available with Twiga Eco Insul products for better vapour control or noise absorption as per application requirements.
