We’ve dedicated our business to providing energy saving products that effectively insulate period properties, yet at the same time are sympathetic towards the unique traditional features. CosyHome Insulation products will allow you to save energy, reduce heat loss and cut your heating bills without sacrificing your home’s character and beauty.

CosyGlazing is a unique secondary glazing system that is elegant, effective and unobtrusive. Made of plexiglass - a modern, lightweight equivalent to glass - and fixed using magnetic strips, it is easy to remove for cleaning. It can be supplied in white or with a wooden frame to complement your property.

•  CosyGlazing reduces heatloss from single glazed windows by 70%
•  CosyGlazing fits to every type of window and you can open your windows as usual
•  CosyGlazing is approved for Grade 1 and Grade 2 Listed Buildings
•  CosyGlazing is made from Plexiglas, which is used for airoplane windows.

Unlike conventional secondary glazing, which has a large aluminium frame,CosyGlazing mounts directly on to the opening window sashes, making it virtually invisible from the inside or outside, and allowing you to open your sash or casement windows as usual.
