Casement Windows
If you’re trying to make your home more energy-efficient, your best bet is casement windows. Dalmen Pro offers a selection of casement-style windows in our Omni, Optima, and Renaissance series, able to match the décor and style of any home. And their design allows you to move from maximum ventilation to unbeatable insulation simply by opening or closing your window.
The Ultimate Energy-Efficient Window
What makes the casement window so energy-efficient? There are two features that come into play—its superior ventilation, and its ability to create an airtight pressure seal. No window ventilates quite like a casement does. It’s not just that it can open more widely than any other window on the market (though that helps); it’s that its shape when opened at an angle acts like a sail, guiding breezes right into your home, even when the wind’s blowing at an awkward angle. And unlike hung or slider windows, which simply slide shut, when you shut a casement window, its sash seals into the frame, restricting airflow, keeping your home’s temperature regulated and your heating and cooling bills low.
As the perfect complement to both your window and your home, our casement windows are available in Omni Series PVC, Optima Series PVC-aluminum hybrid, and Renaissance Series—which unites a PVC or aluminum outer frame to a wooden inner frame via a PVC core—frames, and are made with our best low-E, energy-efficient glass. Casement windows are a perfect choice for any home!

Double Glaze 
- 1. Seals: Specially-formulated silicone provides outstanding durability when exposed to moisture and UV exposure and provides long-term adhesion as well as structural integrity.
- 2. Spacer The no-polymer content waives the risk of chemical fogging. The spacer, made from stainless steel, provides maximum area for primary and secondary sealant coverage, as well as less stress on the seal system and increased resistance to condensation.
- 3. Desiccants Optimum moisture absorption and minimal effects related to temperature and pressure changes are assured by the beaded molecular sieve which provides initial frost points below -53°C Desiccant.
Double Glaze LOW-E 
- 1. Seals: Specially-formulated silicone provides outstanding durability when exposed to moisture and UV exposure and provides long-term adhesion as well as structural integrity.
- 2. Spacer The no-polymer content waives the risk of chemical fogging. The spacer, made from stainless steel, provides maximum area for primary and secondary sealant coverage, as well as less stress on the seal system and increased resistance to condensation.

Energy Saving Dalmen Pro Double Low-E
The options are not limited when it comes to Low E glass types, there are numerous types available to suit virtually any climate. When considering energy efficiency for Canadian weather, it’s important to know that Dalmen Pro Windows uses a superior and most beneficial product. Low E is a microscopically thin coating containing layers of metal and metal oxides that is unique and does not affect clarity.
This coating works together with an argon-gas-enhanced airspace, which significantly reduces the amount of hot rays from the sun entering the home in the summer. It also reduces energy costs of both heating and air conditioning by trapping interior climate conditions.
Low E glass is available for all Dalmen Pro windows and doors. Thanks to Low E’s innovative design, it works to protect your curtains, furniture, and flooring from fading by resisting damaging ultraviolet rays.
The Low E Difference
Low E is a thin coating designed to reflect heat that invisible to the naked eye. It can reduce your monthly utility bills as well as the size of your carbon footprint by improving the energy efficiency of your home.
Triple Glaze 
Three panes of glass with two spacers is a major step up from double pane windows as it offers greater performance when comparing factors such as R-Value*.
Due to the harsh winter climate in Canada, windows consisting of three panes, with a glass spacer for separation, are required for all residential applications.
- 1. Seals: Specially-formulated silicone provides outstanding durability when exposed to moisture and UV exposure and provides long-term adhesion as well as structural integrity.
- 2. Spacer The no-polymer content waives the risk of chemical fogging. The spacer, made from stainless steel, provides maximum area for primary and secondary sealant coverage, as well as less stress on the seal system and increased resistance to condensation.
- 3. Desiccants Optimum moisture absorption and minimal effects related to temperature and pressure changes are assured by the beaded molecular sieve which provides initial frost points below -53°C Desiccant.
*R-Value: esignates window resistance to heat flow. Windows with higher R-Value are more efficient in reducing winter heating costs. (This number is the inverse of U-Value).
