On a rail that can be integrated into the floor, the folding door that easily folds into many pieces allows to fully open walls of up to 6m in width. The folding doors have been produced using our window profiles ensuring unity. It is possible to choose the opening type as needed whether it is all to one side, to both sides from the middle or however necessary. The folding door option is a very popular product in summer cottages, relaxing areas in private homes and hotels alike. Choosing between two different thickness profiles we cover needs from standard thermal transmittance requirements to near passive.

AS Lasita Aken produced its windows and doors mainly from pine (it is possible to choose from finger jointed or solid pine) but also from premium timber such as oak and meranti.

All of the timber used is bought from reliable partners whose products have certificates of compliances and necessary documents. The timber goes through multiple quality checks and all non-complying material is removed from production.

For increased stability, the scantlings are glued together from three or four lamellas and in principle are faultless from all sides. Raw material passes double quality inspection: primary inspection at intake of materials (visual inspection of moisture content and conformity) and secondary inspection at selection of materials prior production. The material is chosen based on moisture content, bending and wood defects and if possible materials with similar structures and colour shades are used together.

PINE (Type: Scots Pine; Pinus sylvestris – Latin)

Air dry density 480-530 kg/m3.
Most used tree species. Timber is with average strength, measure stable to humidity and is not impact resistant. For the solid material, the exterior lamellas have unified structure and tone throughout the lamella. For finger jointed material, differences in in structure and tone may occur.


MERANTI (Type: Shorea SPP – Latin)

Air dry density 580-770 kg/m3
The colour of unprocessed timber is from dark red-brown to lilac-brownish. Measure stable to humidity. Until three meters, solid, without finger joints material is used. Where possible, a batch contains materials with similar shades but differences may occur. To eliminate this, darker tones a recommended where differences are not seen.

OAK (Type: White oak, Quercus alba – Latin)

Air dry density 690-700 kg/m3
The timber is hard yet flexible with good strength properties. Very resistant to decomposition and extremely resistant to wood diseases. Solid material is used up to 4000mm. For longer details finger joints are used.


Good glazing is an essential part of any good window. In addition to the excellent energy saving characteristics quality glass units nowadays have, they offer many possibilities for comfort and protection. In our products it is possible to choose as extra between tempered and laminated glazing for protection, solar protection glazing to keep away the hot summer sun, sound reduction glasses as well as self-cleaning glazing. A well thought through glazing package ensures comfortable living for many years.



A well picked handle is for a window like an icing on a cake working both as an interior design element and a functional tool. As standard we supply handles in a variety of colours from the Hoppe Tokyo design. As per request, it is possible to choose from a wide range of handles.
