What are your windows and doors constructed from?

German System Windows are constructed of timber aluminum, vinyl (UPVC) and aluminum which fit perfectly for any kind of project (residential, commercial).

Why choose energy efficient windows?

Energy efficient windows are an important consideration for both new and existing homes. Heat gain and heat loss through windows are responsible for 25%–30% of residential heating and cooling energy use.

If you are selecting windows for new construction or to replace existing windows, it’s important to choose the most efficient windows you can afford that work best in your climate.

If your existing windows are in good condition, taking steps to reduce the energy loss through windows can make your home more comfortable and save you money on energy bills.

You have two broad options if you hope to reduce the amount of energy lost through your windows and improve the comfort of your home:

  1. Update your existing windows to improve efficiency
  2. Replace your windows.

What kind of warranty do you offer?

We offer a lifetime warranty.

Do you offer installation of your products?

German System Windows has a qualified installation team to get the job done right, regardless of the project size.

What colors are available?

Most of our products are available in 360 RAL colors. We also offer custom colors.

I have an older home and I want to replace the windows and doors. Can German System Windows replicate the look of my current windows?

Absolutely, German System Windows can manufacture windows and door units based on your specifications in order to meet your criteria.

10 Reasons to choose European Tilt and Turn Windows

1.Energy Efficiency

        Who wouldn’t like a lower energy bill? And while you’re saving money, why not lessen your

environmental footprint? The majority of Tilt and Turn style windows and doors utilize materials and

production methods that better regulate indoor temperature, improving energy efficiency and

minimizing the damaging environmental effects that contribute to climate change; due to an ability

to regulate indoor temperature, these clever windows and doors contribute to lower heating and cooling

costs, with energy savings upwards of 60% for an average home.

2.Temperature Control

         Opening windows on a hot summer day instead of cranking the AC is a gallant gesture, but not

necessarily an efficient one this creates air flow but not air exchange. Alternatively, turning up the

heat on a chilly Northern American fall or winter day won’t solve your temperature woes; this will only contribute

to ever increasing heating costs and environmental damage. Tilt and Turn windows and doors contain

a thick, durable air chamber built into the frame. This feature prevents cold air from being transferred

to the middle air chamber, and inhibits warm air from escaping the resulting ‘air lock’ keeps your home

comfortably cool in the summer, and cozy and warm in the winter.

3. Sound Reduction

       Noise pollution can be a serious problem, especially in urban areas with heavy traffic. Even in quieter

residential areas, you and your family could easily be awoken by a sound in the night, such as the

neighbor’s dog barking or a baby crying. Tilt and Turn style windows and doors provide substantial

noise reduction, and lead to less noise in rooms where they are installed; the rubber seal and multi

point locking mechanism creates an airtight seal which improves insulation and limits noise

impact, providing you and your family with some much needed peace and quiet.

4. Easy to clean

It’s rare when a window can make cleaning easier. With the window placed in the turn position,

you can safely clean the exterior of your windows while inside your home. That means no ladders or extra effort.

A seasonal chore easily becomes normal maintenance with a simple turn of a handle.

5. More secure

For a Tilt turn window to function it requires more robust internal hardware with multiple locking points.

Additionally, the in-swing hinges further secure the window from being forced/pulled open from the exterior.

The tilt position also aids in security while still enabling ventilation. The inward tilt still allows the window to remain open

with little ability to maneuver the window fully-open by unwanted “guests”.

6.Better Air-Seals

The performance of a tilt and turn window is one of the less obvious ways this window is superior to its competition.

Better air seals yield a tighter seal, creating an air-tight window. Traditionally, sliding, single hung, and double hung windows are much

more prone to air and water leakage due to their lack of air seals and poor quality. However, GSW Tilt Turn windows boast 2-4 air seals

per window creating a truly air-tight high-performance product.

7.  Aesthetic Hidden Sash

Many of our clients prefer minimal design, so our hidden sash style is a welcomed option.

The Hidden Sash frame mimics the look of our fixed windows, while providing the function of a fully operable

window. This allows for architectural lines to remain consistent with uniform window frames throughout, regardless of window type.


        When renovating your home, you undoubtedly expect your new windows and doors to stand the test

of time (without compromising your budget). European style Tilt and Turn windows and doors are

engineered to provide long lasting performance; from steel reinforced framing to a compression seal

sash with two weather seals, they provide lasting style, function, and peace of mind, without breaking

the bank.

9. Easy to use

Cleaning windows and doors is a task that we all dread, but the Tilt and Turn style simplifies cleaning;

exterior and interior surfaces can be effortlessly cleaned from inside of the room.

There’s no need to hire professionals to clean your exterior window panes, and there is certainly no need to climb a ladder to an upper story window to complete this task yourself.

10. Hidden Hinges

All our windows are available with hidden hinges, truly enabling a clean effortless look. This sleek option gives the illusion

of a fixed window while remaining operable. Plus, no obtrusive hardware distracting the eye, lends itself to a more modern aesthetic.


What is argon gas and why is it used with Low-E glass?

Argon is a safe colorless, odorless, non-toxic, non-flammable inert gas. It is used to reduce heat loss in sealed units by slowing down convection in the air space. Commonly it is used in place of air between the glass panes of an insulated Low-E glass unit. Argon’s heat conductivity is lower than that of air and thus, it is a better insulator and contributes to a lower U-factor. Argon is not an effective solar performer by itself and so; it is used in conjunction with Low-E insulated glass. Argon gas is a relatively inexpensive option, and can easily recover its cost in heat savings.

What is a Premium White SuperSpacer® and why is it important?

The Premium White Super Spacer® is the best performing solution on the market. SuperSpacer® spacers have a conductivity rate 45 times lower than aluminum spacers. SuperSpacer® Premium helps to reduce your condensation problems, and also reduces the risk of thermal breakage. When you are planning to build or renovate, demand the Premium White SuperSpacer® for your windows and doors and assure yourself of comfortable viewing throughout the seasons.

What is the U-factor?

The U-factor or U-value is the measure of a window’s thermal efficiency, based on its resistance to the flow of energy. The lower the U-factor, the more thermally efficient the window is. Most new window technologies have been aimed at lowering the U-factors through the use of three important innovations: Premium White SuperSpacer®, low emissivity glass coatings and argon gas.

What is low emissivity glass?

Low emissivity glass, commonly referred to, as Low-E is glass that has been coated with a micro-thin metallic film to improve thermal performance. The coating reduces the transfer of heat rays through the glass while still allowing light to pass through. In essence, the coating reflects heat back toward its source. Thus, heat from the furnace stays inside the home during cold weather, resulting in greater comfort and lower energy costs. Low-E coatings also reduce harmful ultraviolet rays that cause drapes and upholstery to fade.
