Nu-lok quality is BBA assured
All can now benefit from quality assurance when choosing a roofing system, as Nu-lok Roofing Systems announces British Board of Agrement (BBA) certification.
It was selected over a resin-based roof product for its durability and colourfastness, both of which are guaranteed for fifty years.
Roofing challenge Cedar Court was constructed seven years ago and comprises two three-storey blocks of apartments, each with a complex roof design.
A Mansard roof of 70deg pitch rises to a higher roof with a pitch of 35deg.
In addition, the roofline is interrupted by twenty dormer windows with curved profiles.
The buildings were originally constructed with a double-lapped, resin tile roof, but residents had suffered a series of leaks as well as loss of slates in high wind conditions.
There had also been unacceptable loss of appearance due to fading.
Following a report by NHBC-appointed roofing consultants Michael Kilbey Associates, and in conjunction with the Residents Association, it was decided to have the roof replaced.
A Felts Building Contractors were appointed as the approved main contractor for the project and Cobsen-Davies Roofing (Bicester) Limited undertook the roofing works.
It is usual under these circumstances to replace the defective roof with like-for-like.
Cobsen-Davies quoted for an equivalent resin roof type, but also offered Nu-Lok as an innovative alternative solution.
Innovative alternative solution.
The patented, highly innovative Nu-Lok Roofing System can halve installation times, reduce overall project costs and minimise future maintenance while providing a high quality, traditional slate effect.
Although new to the British market (the system was officially launched at Interbuild 2004), hundreds of thousands of square metres of Nu-Lok have been installed or specified already on construction and refurbishment projects in England, Northern Ireland, America and Australasia.
The system comprises a patented metal fixing system that replaces traditional timber battens with a heavy gauge galvanised steel batten.
The Nu-Lok Link Channel then snap-fits between the battens without the need for additional fixings.
Each Link Channel features a high-grade 316 stainless steel locking clip, used to secure the leading edge of each slate.
Designed to eliminate the need for side-lapping of slates, the Link Channel routes rainwater onto the surface of the ceramic slate below.
The innovative fixing system is used with Nu-Lok's proprietary vitrified ceramic slates, which are virtually non-porous (<0.03%) and will not sustain biological life, preventing moss and algae growth.
Their traditional slate appearance provides a high quality aesthetic finish on new buildings and also wins favour with planning authorities in conservation areas where the existing roofing material is predominantly slate.
A significant benefit of Nu-Lok Ceramic Slates is that each slate is through-coloured, making fading literally impossible.
Their high compressive strength, flatness and excellent dimensional stability mean future warping is eradicated.
All these features ensure that a Nu-Lok roof requires little or no maintenance and will continue to look as good as the day it was installed.
Outstanding performance.
With the NHBC's consent, Nu-Lok was specified for installation at Cedar Court.
Because of the problems experienced with the original roofing method, durability was a deciding factor - as was the colourfastness of the tiles.
Nu-Lok not only met these requirements, it brought additional confidence because of the 50-year Performance and Colourfast Guarantee offered as standard by manufacturers Nu-Lok Roofing Systems (UK) Limited.
Approximately 850mư of the new roofing system was fitted across both apartment blocks by Cobsen-Davies Roofing (Bicester) Limited.
The roofing contractors found the system very easy to install, as Peter Edwards, Managing Director of the Bicester operation, explained.
"The Nu-Lok Ceramic Slates are incredibly easy to handle because they are lightweight and uniform in shape.
The ceramic cuts to a perfectly straight line every time, so we achieved an excellent finished quality." Above all, Mr Edwards was impressed with the ease and speed with which a Nu-Lok roof can be assembled.
"The potential for this system is huge.
I reckon it could double the area of roof we can lay in a given period.
A competent gang can lay around 500m2 in a week.
With Nu-Lok, I could install double that area on my own once the battens are down.
This ease of installation, combined with the high quality finish and durability of the system, makes Nu-Lok pretty awesome." Introduced to Britain less than one year ago, the Nu-Lok Roofing System is taking the market by storm.
It has already been selected over traditional roofing products on a number of specifications where Nu-Lok is to be used in conjunction with the Kingspan TS 1000 Tile Support System.
The two products are ideally suited to each other: a fact that has not escaped the architects!.
