Wall capping provides two beneficial services to both existing and new parapet and perimeter walls.
Wall capping is now recognised as the most cost effective means to protect and weatherproof existing structures and also provides a very attractive, cosmetic improvement to the line of any building.
When considering new structures, wall capping is often specified as part of the building programme to minimise any future maintenance. The capping can be supplied in a range of polyester coated colours that can merge and become part of the overall colour scheme of the project.
For long term, virtually maintenance free, protection we would recommend considering NLC wall capping systems.
Technical Specification
The 'Elite' wall capping range is manufactured from aluminium alloy 14 gauge (2.0mm) to BS 1470 SIC.
Sizes
The capping systems are manufactured to suit each individual wall. The dimensions of the girth of the wall must include any previous rendering etc. Standard length of wall capping is 3.0m.
Accessories and Fittings
All 90° and non-standard angles are fabricated and welded in house. There is a wide range of stop-ends and 'T' sections individually manufactured to suit each application.
Fixings
The capping system is fixed in position by clipping both edged of the capping under the internal connecting collar. The system ensures minimal visibility of fixings from ground level.
The internal collars are fixed to the top of the wall at prescribed intervals using HPS 6/5 hammer screws of stainless fixings.
Applied to each internal connecting collar are tow strips of low modulus sealant. The sealant will allow thermal movement without the possibility of leakage. An expansion gap of 3mm should be left between section to accommodate any movement.
