The Environmental Advantages of using  Kytun Dry Roofing Products

The UK & Ireland’s climate is becoming wetter as average temperatures rise.  Rainfall events are becoming more frequent and are heavier, with the increasing likelihood of extreme weather events such as floods, storms and heatwaves. 

The revision of BS 5534 in 2014 was as a result of the increased frequency and intensity of storm events. The roofing industry has seen quite a rapid shift away from a reliance on mortar to keep roofing materials in place and towards mechanical and dry fixing, with systems for use at ridges, hips, and verges.  Natural building movement and wind forces will cause mortar bedding to crack and ultimately fail, making it ineffective.  By contrast, dry fix systems can cope with settlement by allowing a degree of movement in the surrounding materials.

Aluminium is called the ‘Green Metal’ because it is one of the most environmentally friendly metals on the planet.  It is the most abundant metal in the Earth's crust and the most recycled of any industrial metal.  Of the more than 1 billion tons of aluminium ever produced, roughly 75% is still in use today thanks to recycling.  Recycling aluminium saves 95% of the energy required to produce aluminium from raw materials.  Consequently, it is one of the most valuable items in your recycling bin and ultimately the most recyclable industrial material.

Whilst PVC and other plastics are extremely popular materials for dry fix verge systems, aluminium is increasingly being seen as a superior alternative material for roofing products.  As well the environmental benefits of aluminium, it also offers some great advantages over uPVC.  Aluminium is stronger than uPVC, which means products can be slimmer and lighter and transport costs are lower.  It is highly corrosion resistant and, with an expected service life of over 45 years with little or no maintenance, lasts longer than uPVC.  Aluminium can be supplied in a huge range of colours, with more vibrant colours than plastic.
