Consumer Protection and Building Control Compliance but With A Difference

Building Control Compliance only when and where necessary

Whether you’re in London, Surrey, Kent or on the Isle of Wight Building Control compliance is necessary when a window or a door is renewed including the sub-frame. In other words complete replacement. However with the majority of projects we’ve encountered this isn’t necessary but if upon survey we recommended that the sub-frame should be replaced then as the householder you are required to obtain a certificate of Part L Building Regs compliance. This rule is the same for all London boroughs and throughout the UK. It’s only exempt in listed buildings and some conservation areas. At Sashpro, we don’t approach a project assuming complete replacement and over the years we’ve come to consider it ‘good practice’ to make further use of seasoned existing sub-frames deemed to be in fair to good order for one simple reason. In period houses the works required for renewal of sub-frames can have an effect on the structural integrity of buildings where original timber lintels will have lost their tensile strength and will have partnered with sub-frames to support an elevation, especially a bay window or a doorway that has historic stucco works featured.  This sympathetic approach is a cut above the average supplier, we’re proud of our learned (sometimes the hard way) knowledge and so we want to partner with customers engaged on projects that protect our historic building stock, not through ignorance dismantle it.

Policies governing general environmental issues have become local Building Control legislation dictating specific insulation values (known as u-values) that a new period replacement door or window should have ‘built-in’. Various organisations such as FENSA were set up in order to regulate primarily the plastics windows sector due to the bad behavior often experienced by consumers in an unregulated market.

Sashpro’s Consumer Protection Plan

At Sashpro we not only offer you unparalleled buying protection through our connections with regulatory bodies such as the BBS and White Paper guidance from English Heritage but we also ensure that your purchase is protected with a comprehensive insurance backed guarantee. Further to that our own in-house complaints and quality assurance directives and procedures are in place should anything happen during the process that you’re either displeased with or unsure of.

If you live in a period house the rules are in favour of you – thanks to some intervention from English Heritage – that’s because your local planning office wants to keep its housing stock in pristine period condition. While the insulation value calculations are the same as for other types of fenestration, aesthetic value is just as important a consideration. Our clients can expect a finished product that will not compromise on the traditional look and feel of an English made period window or door but neither will they be compromising  Building Control Regulations Part L.

We achieve this by the way we plan and construct each fenestration project we encounter. We choose our working timbers both for their inherent durability and the natural thermal properties they possess. For example, a hardwood timber section will offer tensile strength but this is not all we’re looking for. Temperature transference within the grain of hardwood is quicker than with some high grade softwoods and the result is a colder framing element. The result of our research into grading timbers for their U value along with state of the art glazing means we can achieve Part L Building Regulations that are within period dimensional detail.

All this allows for a more sympathetic interpretation of the general Building Regs resulting in your project getting the best of both worlds – a product that not only serves to insulate your home but one that looks right as well.
