Our objective is to provide simple and valuable advice on how to control your storage environment, the installation process, and moisture content to make sure you take full advantage of the performance capabilities Bereco windows and doors have to offer.
All our products are made from FSC® 100%, multi-layered, defect-free timber. Opposing grain direction applied during the engineering process, combined with removal of natural defects helps add significant strength to product sections.
Our products are finished and protected by a Teknos factory finish system. Both are water repellent and flexible to expand and contract with the natural movement of timber. Teknos’ microporous finishes allow a natural transfer of moisture vapour between the joinery and the atmosphere
While protecting our factory-finished components from damage is well recognised, it is also vital that basic precautions are taken to prevent excessive change in the moisture content of the timber. In addition, it is essential that our products are installed level and plumb to 1/1000 degree in accordance with our Installation Guidelines and Part L of the Building Regulations.
An incorrectly installed window or door cannot only affect the operation of our products but it can also have a negative effect on their performance capabilities. Cold bridging, significant air/heat leakage, and water infiltration are all potential issues that can arise from an incorrectly installed windows or doors. An incorrectly installed window or door would also invalidate any related warranties.
The moisture content of timber changes constantly with variations in the ambient temperature and relative humidity. Excessive moisture content can cause dimensional changes through swelling or shrinkage of components, blistering, localised failure of the surface coating, bowing or twisting of the timber, cracking of glazing units and operational issues.
The manufacturing process is carried out in a controlled environment, ensuring that all timber products are supplied at 12% (+/-2%) moisture content.
In typical UK conditions, timber dimensions will vary approximately 1% for every 3% change in moisture content. Our design allows for this movement, what it does not allow for is excessive moisture. Products that are fitted in an uncontrolled and unheated building site environment means that the moisture content can increase up to and exceeding 25%. This can cause dimensional changes as large as 3-4% (which would equate to 2.5mm+/- in size causing windows and doors to stick and even not close).
Whether you’re a homeowner working on a renovation project for your home, an architect looking for specific windows and doors, or a trade professional building new homes and properties, we offer a tailored service to help you budget, design, and order bespoke timber windows and doors.
