Can IKO Polymeric calculate the number of fixings required to secure the roofing system?
Yes, IKO Polymeric can undertake wind uplift calculations, in accordance with EN 1991-1-4 to design the fixing layout needed for a specific roof. This calculation must be carried out prior to installing the roof system to ensure it is adequately secured against wind uplift forces. Please contact our Technical Services team or your local Business […]
Can IKO Armourplan and IKO Spectraplan roofing systems be installed in adverse weather conditions?
Generally speaking roofing systems should not be installed in adverse weather conditions. It is not recommended to trap water within the roofing system and roofing materials should be kept clean and dry. Generally adhesives, cleaners and sealants have a +5⁰C operating limit restricting their use in colder months. In cold weather conditions a mechanically fastened […]
Can you manufacture a special colour membrane for my roof?
Yes, IKO Armourplan membranes can be manufactured to any RAL reference colour. IKO Spectraplan TPE membrane colours are harder to formulate, and you should check with your local Business Manager to find out what is possible. Minimum quantities apply to bespoke colour production runs.
What standard colours are available in IKO Armourplan and IKO Spectraplan membranes?
IKO Armourplan is available in Mid Grey (RAL 7046), Slate Grey (RAL 7015), and Light Grey (RAL 7047) colours. IKO Spectraplan is available in Light Grey (RAL 7035). Please note these are the closest RAL numbers.
What is the minimum drainage falls for a single ply flat roof?
The recommended minimum fall for a flat roof is 1:80 (0.72⁰). This applies whether the waterproofing is a polymeric single ply membrane, a reinforced bitumen membrane, or another type listed in BS 6229:2018, the code of practice for flat roofs with continuously supported flexible waterproof coverings. To achieve a 1:80 fall, the code of practice […]
Issue 9: ballasted or buried roofs
The following guidance should be followed when a flat roofing area is to be overlaid with a permanent system such as heavy-duty timber decking, paving, ballast, or bio-diverse (Green/Brown) systems. Any such roofing project must have an Electronic Leak Test carried out once the waterproofing is completed and before the finished surface materials are installed. […]
Issue 8: preparation of in-situ concrete decks
In-situ Concrete for roof decks shall be specified and produced in accordance with BS EN 206:2013 and installed in accordance with BS13670:2009 and the National Structural Concrete Specification. Normal Weight and Lightweight concretes are suitable substrates for most IKO Waterproofing system applications. As defined in BS EN 206:2013, Normal Weight and Lightweight concrete shall have […]
Issue 7: rippling in Spectraplan TPE membranes
Spectraplan TPE membranes can exhibit surface rippling, particularly with changes in temperature, the effect is also noticeable when the daylight changes from dispersed or diffused light of a cloudy day to direct sunlight. This is an inherent feature of the membrane as a result of in-built extensibility during the manufacturing process. The effect will normally […]
Issue 6: roof maintenance guidelines
All polymeric membranes 1.0 General Roof maintenance, as with any part of the building, is essential in order to comply with the waterproofing system guarantee and to ensure maximum performance and life expectancy. 2.0 Access Access to the roof must only be allowed under supervision of the Building Manager or the person responsible for building […]
Issue 5: guidance for working with IKO Polymeric systems in cold weather
Use of adhesives Generally both PU Adhesives and contact adhesives should not be used if the temperature is below 5° C, they should also be stored at 15+°C. Storing the adhesives on the roof overnight during low temperatures is considered poor practice and should be avoided. If this is unavoidable then provision should be made […]
