ENGINEERED TIMBER
Engineered timber is made from short piecies 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.
WOOD SPECIES
PINE
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.
OAK
Main hardwood used for our windows and doors. Oak is the most popular hardwood, naturally beautiful, heavy, durable and strong.
ACCOYA
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.
PAINTS by TEKNOS
TEKNOS is a global coatings company which offers a wide range of paints and coatings for the manufacturing industry, building professionals and consumers.
Teknos coatings help to control the inherent properties of different timbers. They minimise discolouration, maximise durability and protect against problems such as blue stain and mould.
Whatever the combination of timber species, colour application method, Teknos have a system that enables to create a lasting and attractive finish. In addition to traditional joinery they also offer coatings for composite wood and aluminium wood windows and doors. Developed to target key requirements of manufacturers, Teknos use quality binders which keep yellowing and discolouration to a minimum – a key consideration for white or translucent finishes.
GLAZING by ALTEHS
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.
OBSCURE GLASS available in various patterns to suit all locations and personal taste. Some examples below:

HARDWARE BY ROTO
ROTO hardware system is based on a proven concept which, thanks to a very wide range of accessories, covers practically all the customers’ needs and meets individual demands for making day-to-day living more pleasant.
ROTO hardware boasts a high level of basic security even in the basic version and so provides greater burglary protection right from the outset.
QL SEALS by DEVENTER
Deventer weather seals offer complete solutions for windows and doors. Wind, water, smoke and fire are the types of conditions these protect against. Not only do they protect against the elements but are also a useful addition to minimise energy waste by keeping warmth in and stopping draughts. With rainstorms and strong wind becoming more frequent, the functioning of your windows and doors can be easily affected so administering these seals will aid this. Seals have been substantially tested and the quality of their design means they are incredibly resistant to water and wind. For reinforcement, all seals can be applied to windows and doors that are wind and water tight. The special closed cell structure that these seals are made up of is the reason that the seals are so effective and resilient against the elements.

“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.”
