Alpha Clad offer a large selection of high performance thermal and acoustic insulation, ranging from glassfibre and rockfibre quilts to acoustic slabs and polyisocyanurate boards. All of our glass fibre and rock fibre type insulation quilts are classified non-combustible to BS476 Part 4, meet  Euroclass A1 to BS EN ISO 13501-1 and achieve very impressive thermal conductivity (lambda value) figures.   These quilts are odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage fungi, mould or  bacterial growth.  However, it is important to stress that not all quilts supplied within the construction industry are the same!  Products  used within the cladding construction industry should have lambda values of 0.040 or better.  Therefore, you must  ensure that ‘U’ value performance quotes are for comparable products and the thermal conductivity value is  stipulated within the calculations.  Typical loft type insulation, available from the major DIY suppliers tends to only  achieve a lambda value of 0.044.  If this insulation is used, in the thicknesses we quote, it will not meet Building  Regulation requirements.  The way the insulation is placed during construction is also critical.  Any compression reduces the product’s  performance.  Therefore, spacer compression, indentations from lining panel ribs etc., must be taken into account –  a 200mm quilt compressed into a 160mm cavity will only theoretically perform as good as a 160mm quilt!  Attention to detail at junctions is also important.  Building Regulations Approved Document L2a stipulates that the  building fabric should be constructed so that there are no significant thermal bridges or gaps in the insulation layer  within the various elements of the building fabric, particularly at joints between elements and at the edges of  elements, such as those around window and door openings.  For advice concerning correct product choice, ‘U’ value compliance, acoustic performance and junction detailing  good practice, combined with excellent rates and quick lead times please contact us.
