A thin external wall insulation coating
Cork Spray is a strong thermal insulation coating and with the benefit of this system being spray applied at an average thickness of 4mm, which means there will be no need of further amendments to windowsills, fascias, soffits, plumbing, electrical fixtures etc. This reduces the cost of labour down to a minimum when compared to thick boarded EWI panels.
Cork Spray is ideal for existing rendered substrates, Stone, pebbledash, mismatched and damaged brick work, lowering labour costs. As opposed to painting your external substrate every other year (which is false economy) Cork Spray is also a pre-coloured system.
Cork Spray will provide a weatherproof and durable finish, while remaining breathable and extremely flexible.
Cork is an incredible natural resource, self-sustainable and a carbon-negative material, that helps to also save the planet with the fight against carbon.
Cork Spray stands the test of time and provides a long lasting, traditional or modern coloured uplift in appearance, that will not crack, chip or peel.
