Committed to the manufacture of high quality stabilised timber windows, doors and conservatories, Dendura’s design philosophy is clear-cut – to create the most visually appealing products, utilising the best available components, and incorporating a multitude of sustainable design features to set the standard in terms of aesthetic appeal, durability and energy efficiency.
The exclusive use of stabilised timber is environmentally more sustainable as the manufacturing process utilises more of the tree, dries evenly and offers reduced energy consumption through reduced kiln usage.
In addition to being more environmentally sustainable, the timber stabilisation process creates products with a greater performance in terms of dimensional stability and long-term durability. The process also provides enhanced aesthetics through the selection of defect-free timber.
The stabilising process involves bonding lamels of solid timber together using a high quality PVA glue. This provides the structural and dimensional stability, and allows selection of fine quality pieces of timber for the outer faces.
Stabilised timber engineering ensures that Dendura can utilise a higher proportion of wood from each and every tree increasing the efficiency of manufacture whilst also conserving energy.
All Dendura’s timber is sourced from sustainable managed forests and the use of technologically advanced manufacturing processes ensures minimal wastage. By choosing timber from managed forests the company is utilising a renewable and growing resource; the vast majority of Dendura’s timber is sourced from European forests that are typically growing in size at a rate of 30% per year.
Forests can be very effective carbon sinks by harvesting the timber and converting it into products which continue to store the carbon whilst replanting more replacement trees. Growing trees absorb CO2 from the atmosphere at a rate of 1kg per m3 of growth and convert it into carbohydrates through photosynthesis, releasing the oxygen we breathe.
When it comes to conserving energy there are many facts and figures to consider, but how do you know which figures matter? If you are building a new home then ‘U values’ will probably matter more to you. The U value measures the amount of heat loss through a substrate such as a wall or window. Its measured as/(m2-k) so when doing comparisons the lower the figure the better. However, with windows there are two U values to consider; the Centre Pane U value (CPU) and the Overall window U value.
At Dendura its double glazed units meet CPU value of 1.2w/(m2-k) as standard. Moreover, its traditional range casement window is accredited with BS6375 part 1, achieving the highest class ratings for air permeability and exposure.
