Cementitious screed vs mastic asphalt screed
Correct specification of screed for roofing, flooring or car park applications may seem like a minute detail, but it can have significant implications on building performance. Whilst cementitious screeds have been the ‘go to’ solution for many years, mastic asphalt screed is increasingly becoming an appealing alternative for specifiers and contractors in modern construction. A […]
The best practices of flat roof build ups
Over the last couple of decades, we have seen a steady increase in thicknesses of insulation being used in construction. This has, however, had an impact on design in both the new build and refurbishment sector. In terms of the thermal design of a flat roof, what are the options and the best practices of […]
Offsite construction methods and their benefits
The construction industry is turning more and more to offsite construction methods and the trend will become even more popular in the future. The main reasons behind this are the tighter build programmes, higher levels of cost control and skill shortage that the industry is currently facing. With the implementation of the ‘Construction 2025’ strategy, […]
Rainwater outlets in flat roof design
A lot of rain is falling onto flat roofs, and from the dawning day of the flat roof, it always has done. So, the question is when dealing with the problem of flat roof drainage, why do some people still get it wrong? What do we need to consider when getting an efficient drainage system […]
Adhered roofing applications in cold weather
Use of adhesives in winter months The winter months pose various issues for roofing trades especially when installing adhered single ply membrane systems. Generally, both PU adhesives and contact adhesives are not recommended to be used if the temperature is below 5° C, leaving the roofing contractor with no choice other than changing the system […]
Speedy solution to avoid project delays
IKO has developed a screed solution to reduce the long project waiting times in winter months. Compared to using a traditional screed to create required falls, counter deflection or even out substrates, IKO Permascreed can shorten the project timelines by at least 28 days thanks to its fast-drying capabilities, meaning your building can be watertight […]
What is the difference between tissue-faced and foil-faced thermal insulation boards?
The difference between tissue-faced and foil-faced thermal insulation boards is in which type of single ply membrane solution is most appropriate to be installed in contact with them, and the way in which those membranes are attached. The type of facing also affects the overall thermal performance of the insulation board. The difference between the […]
Are single ply membranes suitable for use on roof terraces and ballasted flat roofs?
Single ply flat roof systems can be used to waterproof roof terraces or balconies, and ballasted flat roofs. The waterproofing should not be damaged by the installation of gravel ballast, concrete paving slabs or timber decking, and it may be necessary to install a protection fleece or separating layer before loading the roof with its […]
What standard colours are polymeric single ply membranes available in?
Single ply membranes are offered in a limited range of standard colours, usually a selection of greys. Non-standard colours are available subject to minimum order quantities and extended lead times. As well as naming the colours of their single ply membrane, waterproofing manufacturers commonly also use the closest matching RAL number, to allow for more […]
