Quantum Profile Systems

Quantum Profile Systems’ Dacatie brand specialises in insulated cavity closers, fire-rated cavity barriers, fire socks and associated accessories designed for window and door reveals in masonry or timber-frame constructions. Their insulated cavity closers (e.g., TF1000, TF2000, Supafix) offer continuous thermal and moisture protection across cavity widths from 50 mm to 160 mm, meeting Part L Building Regulations, reducing condensation and improving air-tightness with zero ODP and low GWP insulation. A full suite of fire-rated options such as TFR1000/TFR2000 (30–60 min integrity) and the XFR2000 (60 min) provides specifier precision for compliance with Approved Documents B and L and supports fire separation in concealed voids.

All Dacatie cavity products are BBA-certified, ISO 9001 and ISO 14001 accredited, and manufactured in the UK using lean processes and up to 50 % recycled PVC‑U. Their design features including push-fit and first‑fix frame formers, check‑reveal options, integrated damp‑proof courses, and frame ties cater to both new-build and retrofit applications. They simplify installation, support thermal performance and fire safety in cavity wall systems, and meet rigorous environmental and regulatory standards.
