Onduline, the light weight roofing systems specialist, has added a ‘new and improved’ range of waterproof highly vapour-permeable membranes to its construction portfolio, further extending its growing presence in the ‘Pro Builder’ market.
BBA certificated ONDUTISS AIR
The BBA certificated ONDUTISS AIR membranes have a high technical specification, including advanced levels of tensile strength, tear resistance and ductility, and are available in four different grades, 100gms, 120gms, 140gms and 160gms.
Having BBA certification means the breathable membranes are suitable for pitched roofs on new build as well as renovation projects.
Superior Technical Strength
Ardit Strica, Technical Manager for Onduline Building Products, said the upgraded range had been specifically created to meet the requirements of the construction sector.
“Membranes may not be something you would typically get excited about, but the technical strengths of this suite of products give us confidence enough to say they are truly market leading,” he said.
“Among their other advantages, their tensile strength, tear resistance and ability to stretch before breaking compare extremely favourably when measured against similar products on the market.
“The last thing a roofing contractor wants is a frustrating rip when they are building up the roof, which will not only compromise the waterproofing but will also lose valuable time and ultimately cost money.
“The focus is very often on the grammage of a membrane, which is important, but it is the technical qualities that sets the range apart.”
Vapor Permeable Membranes
ONDUTISS AIR carries a W1 classification resistance to water penetration and a Class E reaction to fire. Its three layers comprise a microporous film protected on both sides by a layer of polypropylene.
It is suitable for use on roofs with a full deck or purlins as an initial underlay for thermally insulated, ventilated, sloping roofs, and in particular for use under concrete tiles and sheet tiles.
As well as improving the efficiency of thermal insulation, it helps reduce energy consumption, reduces CO2 emissions to the atmosphere, regulates the flow of water vapour and is resistant to high and low temperatures.
The 100gms and 120gms products are available now through selected roofing and builders merchants, while the 140gms and 160gms are being supplied to order for specific projects.
Ardit added: “There is something for all, meeting the requirements of everyone from roofing contractors to architects and specifiers.
“We are delighted to be bringing this range to the professional construction sector, and expect to be introducing further product innovation in the near future.”
