About Us

All Under One Roof
This quality range comes to you from Klober, and is the result of a fresh, innovative design approach.

Each product has been universally designed to simplify both specification and installation.

The products also benefit from other special features, cleverly incorporated through considerable technical expertise and design skills, to enhance either their performance or visual appearance.

In producing the range, full use has been made of the latest materials and manufacturing technology, plus Klober's research findings on all aspects of roofing.

All products are rigorously tested - as you'd expect from a company with a reputation for quality. This includes performance and wind tunnel testing ensuring that every product in the range will stand up to the worst of the British weather and comply fully with British Standards and all other
relevant performance requirements.

For further advice on any aspect concerning specification, design or installation of Klober products, please contact our Sales Office.

Condensation.A rising problem.
Condensation is a symptom of modern living and of today’s preoccupation 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 greater draught proofing, double glazing and fewer open fire places, ventilation is reduced throughout the home - encouraging this moisture-laden air to rise into the roof space. Here too, natural ventilation is virtually eliminated through the use of underlay. The traditional roof void is also cold because of the presence of thicker insulation material. So as the warm, moisture-laden air rises from below, it cools, reaches dewpoint, and condenses on cold surfaces.

If left unchecked, this condensation can cause severe damage to the fabric of the building. Timber can rot, weakening the structure. Wetting will cause timber and timber-based materials
to swell and distort, permanently damaging sarking boards and wall plates. Metal corrosion can occur on components such as roof truss nail plates. Insulation materials will absorb dripping
water and lose their thermal effectiveness. Ceilings could damaged by condensation soaking through. Electrical circuits could be affected. Mould growth will form, and anything stored
in the loft could be permanently damaged.

Solution.
There are two solutions to prevent excessive condensation forming in a roof void, one is to ventilate in the traditional way and the other is to use a vapour permeable underlay that allows
the roof structure to breathe. Klober can offer both, providing a wide range of eaves ventilation systems, slate ventilators and tile ventilators along with a range of vapour permeable underlays that all have BBA Certification.

In recognition of the increased importance of controlling condensation, both the Approved Document of the Building Regulations and the British Standard relating to ventilation have been revised. A summary of the main requirements which apply generally to all new and existing buildings is given here, with specific situations tabled overleaf. It should be noted, however, that anything differing markedly from typical domestic situations may need special consideration.

The Klober roof ventilation products featured on the following pages have been specifically designed to provide the most simple and cost-effective solution to condensation.

They can be used in new build, re-roofing and refurbishment situations, and through their
universal nature will simplify specifications and speed installation.
