MUMFORD & WOOD LAUNCHES NEW SBD CONSERVATION™ CASEMENT RANGE WITH ECO SPECIFICATION OPTION

  • Enhanced Security – BS 7950 and Secured by Design certification.
  • Exceeds current building regulations – BFRC A energy rated.
  • Provides improved sound insulation – 40db acoustic rating.
  • Meets severe weather tests BS EN12211:2000 Class 5.
  • Naturally durable timber with 60 year life expectancy.



Mumford & Wood, the specialist manufacturer of premium quality timber windows and doors, introduces the new, ultra-high performance SBD Conservation™ casement window range with A-C window energy ratings.

Available to order, this traditionally styled flush fitting casement comes with many desirable and technical features that set a new benchmark in window design. The SBD Conservation™ casement is BFRC A -C energy rated which exceeds the requirement of revised Building Regulations for 2010. The BRE Green Guide certifies the company’s environmental manufacturing processes achieve an A+ rated window which stacks up maximum credits in the Code for Sustainable Homes. In this, the higher the credit points the closer specifiers and developers will come to achieving zero carbon rated homes scheduled by 2016. High performance windows and doors contribute towards the control of energy and CO2 emissions adding to the cumulative point score to CSH Level 6.

“This is a product range for the future – it excels at every level – security, energy ratings, BRE Green Guide A+ rated, air permeability Class 4, water tightness and wind resistance and without any compromise in traditional design aesthetics,” says Chris Wood, Managing Director, Mumford & Wood Limited. “Windows in our classic Conservation™ range, which is currently C energy rated, will be enhanced with this high performance A rated alternative.” Building Regulations require a CSH Level 3 performance window by 2010 which equates to a C rated window. This is adequately surpassed by the new SBD Conservation™ casement range.

The SBD Conservation™ casement also meets Enhanced Security British Standard 7950 as required by Secured by Design recognition while the traditional appearance of its design conceals the robust ironmongery that will withstand repetitive and extreme impact tests. A fourth category under the CSH is that of Health and Wellbeing in which improvement to the quality of life in homes through good natural daylighting reduces the need for energy to light a home with artificial light. The new SBD Conservation™ casement uses very clear, low iron glass which achieves good solar gain required for higher energy rated windows and in doing so accounts for those essential CSH points. Double glazed units use argon filled, laminated silence glass which achieves a 40db Acoustic Ratings and is a positive attribute under the CSH Health and Wellbeing category.

These BSI Kitemarked, fully factory finished products are manufactured from truly sustainable laminated and engineered premium quality Larch which is naturally durable and achieves a consistent and knot-free surface. Here the BRE Green Guide A+ rating for use of certified timber contributes toward the CSH total points count. Delivered to site with three coats of water-based microporous paint or stain ensures longer maintenance cycles.

“Perfect for new build or refurbishment, private homeowners and social housing landlords, developers and specifiers can be sure they are meeting all the sustainable targets while providing a comfortable, secure and attractive fenestration system for all property types,” states Chris Wood. “But with all this technology we believe the aesthetics are even better than our much loved, highly popular standard ConservationTM product. With the new SBD Conservation™ casement we have a completely flush timber casement with no visible keeps or hinging systems.”
