Timber

Engineered 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.

Wood species

Pine - softwood

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 - hardwood

Oak wood is characterized by a very good hardness and mechanical resistance, in particular to compression and bending, but also resistance to fungus and mold attacks. It presents a pleasant colours stratification, from the yellowish sapwood to the brown heartwood.

Red grandis - hardwood

Red Grandis is stable, durable and dense hardwood . The colour can vary to almost white to light pink or dark red. Typical uses for this timber are windows, doors, and all aspects of external applications. It is particularly well suited to large items such as door frames as it comes in long engineered lengths so it is less likely to bow and warp; this in turn reduces the need to overlap and finger joint frames.

Meranti - hardwood

Meranti is a soft to firm hardwood timber. This timber is exported from South-East Asia. It belongs to the mahogany species. Meranti is not subject to warping or twisting and is dent resistant. It has natural resistance to rot and moisture, insects and sunlight exposure

Finish

Windows and doors can be finished in any RAL colour or combinations of colours.

RAL is a colour standard created in Germany in 1925, which is widely used when choosing paint colours for painting various surfaces. It is a versatile and widely used colour palette throughout Europe and beyond. RAL Classic consists of 216 Colours. The RAL Design collection includes 1,825 colours. The colours of RAL Classic and RAL Design do not intersect.

You can view RAL colour collections here.

To ensure the smooth operation and optimal performance, our windows have 3 coats of sprayed microporous water-based paint.

Applied in controlled environment, multi-porous spray paints cover all concealed areas of the windows and doors, and are up to 6 times thicker than brush applied paints or stains, therefore offering a long service life with just simple maintenance.

They minimise discolouration, maximise durability and protect against problems such as blue stain and mould.

Glass options

We have a huge rage of different types of glass to choose from.

low-e glass

Low-E Glass is used as a standard in all our windows and doors.

It 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.

toughened glass

Toughened 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

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

acoustic glass

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

obscure glass

Obscure Glass available in various patterns to suit all locations and personal taste.

solar control glass

is a glass with a special coating designed to reduce the amount of heat entering a building. It reflects and absorbs heat as well as filtering light for reduced glare. Using a solar control glass can reduce the need for air-conditioning and blinds. There are many types of solar control glass offering different aesthetic options; tinted, reflective and neutral.
