Highlands and Islands work shows EWI specialist has what it takes

// the building envelope

Alan Hodge, Sales Director for Kilsaran International Ltd explains to HA Magazine what conditions the company has exposed its insulated render system to as it works to build its business across the British Isles.

Drawing on the long manufacturing heritage of its parent company in Ireland – a specialist in the production of paving and other cement based products – Manchester based Kilsaran has spent the past two years making a name for itself in the even more competitive field of façade contracts.

Now with a number of successfully completed projects under its belt, carried out in some of the most challenging climate conditions the UK has to offer - the company is seeking to extend its influence in the overcladding and renovation of existing residential properties; particularly working with social housing providers, whatever the type of building they have in their stock.

Alan Hodge is Sales Director for Kilsaran International Ltd. and has been involved throughout the launch and growth of the new business. He told HA Magazine:  “We were established as a façade solutions specialist and are involved in the manufacture of render treatments as well as the supply of the Ceretherm external wall insulation system, produced by Henkel.

“The latter has proved to be absolutely ideal for the exterior renovation of properties we have worked on in the North of England and Scotland, where the exposure conditions are very harsh. Not only can we offer excellent weather resistance with the choice of a dash finish or a silicone top coat render to shed the rain, but the method of attachment for the insulation boards using a PU foam adhesive and supplementary fixings is very much belt and braces also.

“This features the use of special foam adhesive which on its own meets the requirements of the European standard ETAG 004; before we make use of the drilled and driven plug mechanical fixings. We have done a lot of work on wind load calculations and pull out tests for the different property types we have been dealing with, and their locations, in order to get the fixing patterns right.”

The Ceresit CT 84 foam adhesive which Alan Hodge is referring to is dispensed from aerosol cans to not only offer good initial grab, but it cures in just two hours, compared to two days for cement based adhesives. Furthermore it can be used in temperatures down to 0 degrees centigrade which is a specially important consideration in northern latitudes.

Then the Ceresit silicone based render available for use as the top coat to the EWI system contains a biocide that resists the growth of algae or other processes which might discolour the render. The Ceretherm system also offers the option of additional reinforcement to provide the very highest standard of resistance to mechanical damage from accidental knocks or the repeated pounding of a football. 

Aside from investing heavily in ensuring its actual products and systems are fit for purpose, Kilsaran has also been working to establish a UK wide network of approved installers; having begun its early jobs working with Preston based Trade Energy: itself a specialist contractor for facades. And in parallel with this Kilsaran is in the process of appointing key distributors around the country from the ranks of the independent builder’s merchant chains.

Most recently, Kilsaran and Trade Energy have carried out a pilot project on one of the Scottish islands where the Ceretherm system has been applied across the outer walls to a pair of timber framed semi-detached houses whose thermal and weather performance had saddled the occupants with the double-pronged problems of high energy bills and poor comfort levels. The properties would be classed as ‘hard to treat’ by most social housing providers, even if they weren’t located in one of the UK’s most exposed locations.
