Energy efficient
stormproof sash
This is an enhanced energy efficient version of our stormproof shootbolt.
Using Accoya timber (treated Radiata Pine), our stormproof shootbolt window achieved an ‘A’ rating (with an adapted cill – see inset), the ultimate accolade in energy efficiency. The stormproof shootbolt casement window made from unsorted redwood reached an impressive ‘B’ rating.
