Invisiweep NC New Product Launch

Date Posted: 07th July 2021

At Timloc Building Products, we pride ourselves on our continuous product development to ensure we are consistently delivering the best range of products and service options for you to choose from.

As a result of this continued innovation, we are pleased to introduce the brand new Invisiweep NC – the non-combustible wall weep for use in high-rise buildings.


  • Suitable for use in high-rise buildings with a storey 18m or more above ground level to Regulation 7(2) and Building Regulations Approved Document B.
  • Suitable for use in buildings with a storey 11m or more above ground level to Building (Scotland) technical handbook 2019: domestic and non-domestic, 2.7.

Invisiweep NC is manufactured from high pressure die cast in A1 non-combustible metal protected by an electroplated coating. The non-combustible weep maintains all the great features of our popular Invisiweep, including:


  • Internal 4mm vermin barrier and rainwater baffle
  • External ribs & tapered profile for secure fixing into mortar
  • Full height upstand to cavity side
  • Venturi effect for optimal drainage
  • Discrete water outlet for a truly concealed wall weep

Invisiweep NC is available in box quantities of 50 and on next working day delivery for all orders placed before 12pm. Orders can be combined with the full Timloc range to meet our low carriage-paid order values of £100 to branch or £150 direct to site.
