Cavalok Cavity Closers (also known as cavity closures) have
become a critical and compulsory building component used in all
new-build projects to seal apertures in cavity walls. Our range focuses on rigid, frame-forming cavity closers which
combine several essential features into just one product.
SAVE ENERGY- Dramatically speed-up
and improve bricklaying by using the pre-made cavity frame as a
template, guaranteeing the opening size.
SAVE ENERGY - Fit windows in seconds
with the window acceptor features and accessories of our systems.
SAVE ENERGY - Integrate the closing
of the cavity and DPC into the building process from the beginning.
SAVE ENERGY - Enhance CO2 emission
performance with the thermal break and secure insulation created
by a Cavalok closed wall junction.
