Enviroblinds are pleased to offer a new range of external roller blinds from HAROL, renowned for their quality and design since 1946. The foam filled, roll formed aluminium blinds offer protection against excessive solar gain by blocking out the heat externally. The systems are fully adjustable and control the level of daylight from no shading to full black out. They also have the added benefit of providing additional insulation during cold weather and improving the sound insulation. These systems can be retrofitted or included as new build systems.
