Calcium Organic Stabilised

The raw materials that are used to produce Sheerframe windows are carefully selected to ensure any risk to humans or the environment - whether perceived or actual - is kept to an absolute minimum.

Sheerframe windows were amongst the first PVC windows to become lead-free, with the use of lead additives phased out as a precautionary measure and replaced with calcium organic stabilisers. It is steps like this that ensure the health of the people that manufacture Sheerframe windows and Sheerframe customers can be assured of total safety.
