the centre for ecology and hydrology (CEH) is the UK’s centre of excellence for land and freshwater science.
as part of a £50 million restructuring programme, NVELOPE’s ‘intelligent’ cladding support system has been specified.
the new laboratory building aims to be sustainable and comply with the highest environmental standards and has received an excellent BRE (building research establishment) rating for its design and construction elements.
the building was clad in a renewable material, western red cedar which is naturally resistant to decay and insect attack, offers superior acoustic qualities and is an excellent material for thermal insulation.
to hold the cladding firmly in place and create a robust shell, NV6 NVELOPE cladding support system was specified. the NVELOPE carriers enable the easy application of timber battens on to which the cladding can be fixed.
for a stunning new residential scheme in central london, o-central, architects required a reliable, durable and practical method of fixing the vast amounts of exterior cladding to the building.
designed by architects tate & hindle for oakmayne properties, the building required an innovative approach to the exterior cladding, which could be installed quickly as it was to be completed on a fast track 69-week programme.
tate & hindle specified white render and Trespa meteon rainscreen cladding panels. extremely weather resistant, they are not affected by sun, rain (including acid rain) or moisture. to provide a secure fix for the panels, NVELOPE provided its NV2 (structural adhesive) rainscreen cladding support system.
for o-central, with aesthetics of paramount importance, the panels were held onto the NV2 support system using sikatack panel adhesive, a high performance adhesive system.
NVELOPE produces a comprehensive range of cladding support systems to suit most applications, including vertical fix, horizontal fix and secret fix. as part of a complete technical support package, NVELOPE provides specifiers with a range of tools and services.
a combination of Trespa meteon HPL and cement based petrarch cladding panels were selected for their versatility and colour. to provide a seamless fix of the petrarch cladding, NVELOPE’s NV2 (structural adhesive) rainscreen cladding system was specified.
this system comprises:
• sika tack panel adhesive (activators, primer, tape, adhesive)
• NV2 cladding support system
NVELOPE brackets in a size range from 90mm to 120mm were provided, allowing a cladding zone from 90mm to 160mm to be accommodated. the supports were easily fixed to the substrate of the structure using pre-drilled holes.
designed with sustainable principles in mind, the adhesive fix helps limit cold bridging to provide more effective energy saving temperature control to the structure. the NV2 cladding support system is also easily recycled, being aluminium, so can be re-used at the end of its life for 5% of the energy required for its original production.
this project posed a number of challenges. including access issues and a building with walls which deviated by as much as 70mm in places. to add to the challenge we had to use panels which weigh 45kg and are prone to warping.
NVELOPE worked closely with AJ wells, the manufacturer, to design the system and introduced an installer with the expertise to achieve budgets, time constraints and the high level of on-site skill required to deliver a project such as this.
façade concepts (www.facadeconcepts.com) were the installers who took up this challenge. they knew that there was one company who could supply them with the necessary cladding systems, along with bespoke clips and a speed of delivery and support service which is second-to-none. naturally, they chose NVELOPE.
transport for london (tfl), the client, wanted to create a dramatic, arresting edifice using strongly patterned panels designed by local artist jacqueline poncelet, incorporating iconic themes such as cars and the underground logo, within the abstract patterns.
unusually, the cladding on this building is purely decorative. however, the panels reach right down to ground level, in the street, on the boundary wall side. so the cladding had to be extremely durable and graffiti resistant. vitreous enamel panels are much used by London underground for signage and internal cladding. so this material was chosen for its durability and ability to have pattern applied.
the project required 1,529 square metres of 1.8x1.2 sized cladding panels each weighing 45kg and taking two men to lift. matt, at façade concepts specified our NV3 system to support the panels. however, as the vitreous panels aren’t normally put to this use matt had to specify stiffeners to support the panels, to prevent warping. he also worked with us to develop a bespoke clip to attach the panels to the supporting system.
ordinarily this project would require 60mm brackets for installation. however, because of the 70mm deviation within the walls a range of brackets was used, from 60 – 120mm. in fact, an additional 650 brackets were used to compensate for the deviation.
we were able to provide the full range of brackets, rails and clips for the challenges and bespoke nature of this project. matt small, knew that he would get the service level a project of this nature requires. matt says, “we have had great support from NVELOPE. the service is good and we have trust in them. when i phoned up at 3pm the order arrived on site the very next day.”
thanks to the expertise of our technical design support service our range of brackets and systems can be optimised for complex projects such as this one. we can add real value to the design process, bringing architects and specifiers real freedom.
