The mandatory requirement for the thermal efficiency of buildings, is set out in “The Building Regulations Approved Documents” - Part L for England and Wales, Part F in Northern Ireland and in Section 6 of the SBSA Technical Handbooks for Scotland. To help ensure that the requirements of these documents are met.


The SarnaTherm range encompasses products suitable for use in adhered, mechanically fastened, loose laid ballasted and SarnaVert green roofing applications that have been tested for compatibility with other Sarnafil roofing components (critical in adhered applications). They meet a wide variety of fire resistance, acoustic and design requirements.


Sika Limited's unique Sarnafil Branded Product Supply Agreements, with the industry's major thermal insulation manufacturers, ensures that specifying SarnaTherm provides the peace of mind of guaranteed product compatibility, without the risk of splitting the roofing system guarantee liability between the primary waterproofing and the thermal insulation manufacturers.
