Dacatie Cavity Closers

Subframes UK is an approved fabricator for Dacatie Green Building Solutions, supplying BBA certified cavity closers from 50mm to 300mm in 2, 3 and 4-sided configurations for first and second fix installation across masonry, timber frame and steel frame construction.

Technical specifications

Cavity widths from 50mm to 300mm
2, 3 and 4-sided frame configurations
Thermal resistance meeting the 0.45m²K/W minimum required by Part L
Zero Ozone Depletion Potential; Global Warming Potential below 5
BBA certified profiles across the standard range
Fire-rated protection available via Dacasock FIRESOCK

Dacatie profiles prevent thermal bridging at window and door reveals, reducing heat loss and the risk of condensation and moisture migration across the cavity. The range meets Part L (thermal performance), Part B (fire safety, where fire-rated profiles apply) and Part C (moisture protection).

BBA certification across the standard profile range provides specifiers and contractors with assurance of compliance and performance.

Construction applications

Dacatie profiles suit masonry, timber frame and steel frame construction across residential and commercial projects. The size range covers cavity widths from standard brick and block builds up to 300mm for wider-cavity timber frame applications, supporting both first and second fix installation.

For projects requiring fire resistance, the Dacasock FIRESOCK system works alongside Dacatie cavity closers to meet Part B requirements.
