The introduction of the revised Part L of the Building Regulations in October 2010 has thrown up a number of new challenges for contractors and specifiers. Top of the list is the stipulation of a 25% reduction in carbon emissions for new houses compared to 2006 levels and the significant improvement in U-values within the building fabric. With these new requirements comes the challenge of understanding the changes and creating buildable solutions. Thankfully help is on hand from leading insulation manufacturer Celotex.

Celotex is the market leading manufacturer of polyisocyanurate (PIR) insulation boards and has unrivalled experience in the creation of thermally efficient building envelopes that offer low carbon emission and low U-values. Having created some of the best insulation products on the market, that enable the new targets of Part L to be met, the company is ideally placed to provide essential guidance and support to specifiers and contractors.

The 25% reduction in carbon emissions naturally means there is a need to create better-insulated walls. In many cases this will mean the use of more insulation, affecting buildability. For example, more insulation will affect the size of cavity walls required, which in turn affects the amount of usable and saleable space within buildings. To counter this Celotex, which operates an ongoing programme of research and development, has recently improved the thermal conductivity of many of its products. With a value of 0.022W/mK, Celotex can offer a range of innovative solutions to help meet the new requirements, all achievable with some of the thinnest possible insulation solutions.

As well as offering products that are up to 100% more thermally efficient than some mineral wools and able to deliver up to 10mm savings when compared to typical PIR products, Celotex also offers specifiers and contractors a wealth of technical information and support. As well as advice and guidance from the company’s Technical Centre, Celotex is also offering a dedicated CPD.

“The 25% reduction in CO2 emissions from new build houses required by Part L 2010 will need increased focus on the fabric of the building and tighter U-values will require increased levels of insulation in walls, floors and roofs of new properties,” commented Rob Warren, Celotex’Technical Manager. “Heat loss through party walls, the design of cavity walls and the focus on the design and buildability of elements where thermal bridging can occur, now require additional consideration. As leaders in PIR insulation, Celotex is taking the lead on providing specifiers and contractors with guidance to aid with the understanding and implementation of the new regulations.”
