In addition to legislative changes affecting roofing practices, demand for airtightness is giving rise to increasingly complex roof designs. Klober was the first company to develop a range of tapes, sealants, air barriers, vapour control layers and sealing collars specifically for the purpose of maximizing airtightness in roofs and walls. Their use enables movement of heat, air and moisture through the building envelope to be controlled for greater thermal efficiency and reduced risk of condensation.

Klober tapes and sealants are used to seal laps and penetrations made for pipes, ducting and cables and to bond membranes to other building materials. They provide an exceptional standard of adhesion and are equally effective with either rough or smooth surfaces.

Air barriers and vapour control layers (AVCLs) provide a standard of performance in roofs and walls which far exceeds the requirements of BS9250 making them ideal for Passivhaus / EnerPhit construction.

The range is supported by literature which examines air permeability requirements of Approved Document Part L and the contribution of specific products in SAP calculation. An accompanying CPD presentation is also available.

Klober has been at the forefront of other key pitched roofing developments such as  vapour permeable and air-open underlays, dry fixing of ridge, hip, eaves and verge, solar installation and universal tile vents. Solar installation accessories complement those in the Klober airtightness range as the Microgeneration Certification Scheme now requires the use of installation kits which have been tested and certified in accordance with the requirements of MCS 012. Use of such products is a condition of qualification for the feed-in tariff and Klober kits were among the first to be tested by the British Board of Agrément. In addition to laboratory testing, mandatory factory production control audits have confirmed that management systems are in place to ensure consistent product quality.

Since the NHBC decision that vapour permeable underlays should be supported by high level ventilation Klober’s BBA-certified air-open underlay, Permo® air, has seen a dramatic increase in specification. As the most breathable air-open, low resistance underlay available it provides the ideal solution where there is a high risk of condensation forming in the roof space. The requirement by BS 5534 to print wind zone compatibility on all underlay packaging further endorses the product’s suitability for regions of the UK subject to its severest weather conditions. BS 5534 is also the subject of a Klober CPD presentation.
