Insects.
Our windows can be optionally fitted with insect screens – in the form of a vertical screen roller blind or a fixed screen frame. For maximum protection against uninvited guests. Even when the lights are on.

Darkness, tranquillity, fresh air and protection from uninvited guests – these are the fundamentals for a restful night’s sleep. Well-designed bedroom windows can offer all of these.
Finstral windows are particularly airtight and offer outstanding noise protection, making them ideal for bedrooms.




“The window plays a key role in sound insulation.”

Always properly protected by Finstral windows.
For maximum comfort, particularly in the bedroom, intelligent provision is made to guard against insects, burglars and heat. To keep out what should stay out.
Finstral offers a wide selection of blackout options to meet your own personal tastes – from traditional hinged shutters to innovative shading devices incorporated in the window sash.










Optional features for convenient ventilation.
Good indoor environmental conditions are particularly important in the bedroom: we offer diverse ventilation options for particularly reliable, discreet and energy-efficient ventilation.
Do you just want to inspect, touch and try out our products? At the Finstral Studio, you will find a wide range of windows and doors. Along with expert answers to your questions.
Windows are investments for decades. Which makes intelligent design all the more important. The diversity of design and functional options is far greater than you can imagine.

At a glance.
Darkness, fresh air and tranquillity are an absolute must for bedrooms. To meet these demands, Finstral offers customised windows with uncompromising performance. We make a difference by tackling typical sleeping problems at source. Our highly compact profiles and special sound insulation glazing reliably block out noise. With our Twin coupled sash, we integrate the blackout device in the sheltered gap between the panes. Fixed insect screens keep out mosquitoes when you air your bedroom during the night. Everything from a single source.
In winter, a permanently tilted window will cool down the walls, waste expensive heating energy and freely let in street noise. Instead, experts recommend thorough shock ventilation before bedtime. For those who still need a continuous, gentle supply of fresh air overnight, Finstral’s rebate ventilators, invisibly integrated in the window frame, offer the ideal, energy-efficient and, above all, silent alternative.
If the bed is located directly by the window and children play on it, then safety has to be the top priority. Here, apart from standard burglary protection features (RC 2), Finstral offers window handles that are lockable from the inside and smart “tilt-before-turn” hardware. With the latter function, turning the handle only allows the window to be tilted. A key is then required to fully open it. In this way you can ventilate without any risk of accidents.
Experts recommend cross ventilation several times a day. The duration depends on the time of year: in winter, five to ten minutes with the heating turned off will suffice. Moisture and steam can thus escape with little heat loss while neither walls nor furniture will cool down. Ventilating for 20 to 30 minutes is ideal in summer, preferably in the morning and evening when the outdoor temperatures are lower (Source: BMUKN (Federal Ministry for the Environment, Climate Action, Nature Conservation and Nuclear Safety)).
