We are an official FINEO glass installer

Fineo double glazing for sash windows is already a popular feature on countless Essex homes and with good reason.  Fineo glass is light and thin – only 6.7mm – perfectly proportioned for the narrow rebate of a sash window but yet with the most amazing thermal regulation allowing homeowners to enjoy the lower energy costs and constant warm temperatures usually associated with a much more modern home.  We can adjust the rebate slightly if necessary to accommodate the glass and with barely any additional weight, your sash windows will run as smoothly as ever. 

As a part of the retrofitting process, we also repair windows’ timber frames

Chameleon will ensure that every window is perfectly rebalanced with the new glazing so that the system of weights and pulleys runs efficiently if not better than before.  If any repairs are required then we use Accoya wood which is a new timber with superior longevity and weatherproofing compared to more traditional woods.
