KLOBER Overview of Klober History Klober was founded in i960 in Schwelm, Germany. The philosophy of the company was to manufacture ventilation pipes on an industrial scale which could be installed on any roof - no matter what the pitch. During the seventies, the product range grew to include safety and support products as well as walkway systems and roof windows. By the start of the 1990's Klober entered the market with vapour permeable membranes which strongly influenced the way roofs were constructed. The development of a ridge and hip solution also changed the installation methods within...

KLOBER Introduction to membranes & sealing products Reducing air leakage through the roof With 25% of heat loss traditionally being through the roof, it is essential to use products which both reduce this figure whilst providing adquate levels of ventilation. With increasingly strict legislation gov-erning the energy efficiency of houses, those involved in roofing will need to take advantage of products which will help reduce heat loss including sealing tapes and vapour control layers/vapour barriers. Airtight connections should be made between laps in the underlays them-selves as well as...

Introduction to membranes & adhesive tapes KLOBER Tiling underlays It is common practice to use an underlay below the roof covering as a secondary barrier against wind driven rain and snow. The underlay can also be used as a temporary waterproofing barrier during the construction process but we recommend that the roof finish is quickly applied. Underlays also play a significant part in deflecting wind pressure applied directly on to the roof finish. Traditional felt underlays and the newer plastic/polypropylene based underlays are impervious to water vapour and require ventilation of the...

KLtfBER Condensation Condensation - a rising problem Condensation is a symptom of modern living and of today's proccupation with saving energy by minimising heat loss. The increased presence of central heating, showers and modern domestic appliances produces greater amounts of water vapour in the home. An unvented tumble drier alone can emit as much as 7.5 litres per day. Matters are made worse by the fact that these moisture-producing activities are often concentrated at certain times of the day, followed by long periods when the house is either unoccupied or unheated. In addition, through...

The Control of Condensation in Buildings BS 5250:2002 KLBER BS 5250: 2002 The Control of Condensation in Buildings looks at recommendations to limit the amount of interstitial and surface condensation forming in building structures including roofs. The Standard makes recommendations into preventing excessive condensation forming in roof voids by looking at the two types of underlay used in pitched roofing, the air tightness of the ceiling below the roof structure, and the provision of roof void ventilation when using both types of underlay. Non-ventilated roof structures are not covered in...

KLtfBER Roof types The cold ventilated pitched roof with type HR underlay Thicker insulation means that ventilation accessories become more v intricate to ensure a clear ventilation path is maintained at the eaves Ventilation of roof space allows dust and dirt to accumulate. In some cases insects and birds enter to make their nests High level ventilation may also be required Impermeable or high resistance type underlay will trap water vapour in loft if not adequately ventilated The risk of condensation is greatest on frosty nights with a clear sky Cross ventilation of the roof is essential...
