If we roll back the years to the mid ‘60s and early ‘70s, when the construction of new social housing was at its peak, the choice of window material was almost exclusively timber with some aluminium products being used in mid and high rise blocks. From then on, we have seen the emergence of PVC-U profile as well as composite doors making up the material choices. LHC has been procuring these products throughout that time.

Why work with LHC for windows & doors procurement?

Today, the product performance demands are substantial and the science ever-evolving. Top of the list must be both the on-going requirements for greater energy efficiency and security. Furthermore, weather performance, durability, glazing safety, fire safety and site installation techniques are also continually being enhanced. And, the majority of projects now serviced by LHC are for refurbishment purposes.

As a centre of excellence, LHC must keep abreast of these advances - indeed, we have been at the forefront and, in a number of cases, driven or influenced the improvements. This is mainly possible as a result of our long-standing representation on several BSI and industry technical committees. At a rough count, there are approximately 70 British and European Standards serving all forms of windows and doors specification items. Then there are the regulatory requirements such as the newly introduced Part Q of Building Regulations in England and the longer standing Scottish Building Standard 4.13. 

Benefits of working with LHC for windows & doors procurement

LHC has three of its Technical Team serving on British Standards committees for windows and doors in Chris Powell, Jim Noble and Richard Wilby. Chris has been our British Standards representative for the past 10 years and is Chairman of the committee responsible for drafting BS 8213-4, ‘Code of practice for the survey and installation of windows and external doorsets’. He also sits on several industry technical panels. Jim is gradually sharing this work whilst Richard advises on site practice and workmanship. It is through this representation work that LHC can keep abreast of requirements and proposed developments as well as taking advantage of valuable associated networking.

For example, for our forthcoming Communal Entrance Doorsets Framework (CED1), LHC has set up a collaboration with Secured by Design (SBD). SBD can rightly claim to provide specialist targeted guidance specific to all security related areas of design including the building’s location, external environment, type of occupancy together with a risk analysis of likely vulnerability.

Within SBD’s latest publication of “Homes 2016”, specific guidance on the design considerations applicable to communal and shared entrance doorsets ran in direct parallel to the specification demands being drafted by LHC for our proposed framework and, at the conclusion of detailed technical discussions, it seemed that a “partnership” between us would be a valuable and unique step forward.

In conclusion, when LHC prepares a framework tender specification, we firstly have to ensure all of our performance requirements are fully up to date. Any possible planned future revisions or additions, especially regulatory, are taken into account and flagged up. Our technical committee work is certainly an excellent way of being at the forefront of these developments. As an LHC framework user, our clients have the full complimentary support and expertise of our Technical Team at their disposal.
