VictorianSASH triple glazed sash look alike window


Our VictorianSASH triple glazed wooden window has been designed to replace traditional sliding box sash windows. The sash window replacement resembles the authenticity of the appearance with the heritage and elegance of the classic sliding sash window, but with great airtightness and thermal performance.

Fixed top sash and tilt & turn bottom window sash combines the latest technology, high security and performance with the period features of a traditional sash timber window.


VictorianSASH is an excellent solution for EnerPHit retrofit projects.






" When the windows arrived, we were amazed by both their appearance and the workmanship. We were delighted! No one seeing the house from the front can even tell they are modern windows, but we can, as the house is now warm and draught-free. "  /Juliet and Ray/

"These windows enabled us to maintain the appearance of this fine old house while carrying out a pragmatic retrofit within a limited budget, alongside an ambitious extension to give the clients more living space. The cost of these windows was a pleasant surprise to the builder and the appearance was a pleasant surprise to the planning officer."  /Architect Phil Bixby/

  • -  TIMBER  -


    Engineered timber is made from short pieces of wood  joint, glued, compressed and laminated together to form longer length timber  without knots, splits and stains.

    This solution makes engineered timber stronger and more less likely to warp or twist in wet and humid conditions compared to solid timber.



    Main and most used softwood for our windows and doors. We are using  slow growing pine from Nordic forests. Pine is soft, has medium density and  is easy to work with. Knots are tightly fixed in the timber and are small in size. Being less expensive than hardwood, pine is often the choice of timber when considering your budget.


    Main hardwood used for  our windows and doors.  Oak is  the most popular hardwood, naturally beautiful,  heavy, durable and strong.


    Accoya is a high performance wood made through non-toxic acetylation process of sustainably sourced softwood. The natural beauty of the wood is not compromised during this process. Accoya wood  is exceptionally durable, dimensionally stable  and naturally renewable .  Its properties  match or even exceed those of best tropical  hardwood.

  • -  GLAZING  -


    The glass types available are extensive to suit the needs and requirements of your project.


    LOW-E  GLASS  is specially treated with a microscopically thin, virtually  invisible transparent coating on one surface. The coating reflects heat back into the building, thereby reducing the heat loss through the  window.  This  glass is used  as a standard in all  our windows and doors.


    TOUGHENED SAFETY GLASS is up to five times stronger than ordinary glass of the same thickness. Toughened glass is used where strength, thermal resistance, and safety are important.


    LAMINATED GLASS   is a type of safety glass that holds together when shattered. It provides even greater security levels that toughened glass,  offers better levels of sound reduction and thermal insulation.


    ACOUSTIC GLASS  considerably reduces external noises, especially near busy areas such as motorways, main roads , railways and airports.
