Double and Single Slider Windows
Horizontal slider windows are a convenient choice for anyone looking for a great view and a low-maintenance solution. Dalmen Pro’s selection of single and double slider windows give you versatile choices for your home, featuring an energy-efficient design and durable construction in our signature Omni and Optima Series frames. It’s easy to see why slider windows are such a hit with homeowners!

Convenience in Design, Beauty in Elegant Simplicity
Sometimes the best things in life are also the simplest: a game of catch in the back yard, a tall glass of lemonade on a hot, humid day, a friendly smile when you’re feeling down…
Slider windows work on the premise that sometimes, less is more, so don’t mistake their simplicity for a lack of design. They work without springs, levers, or cranks—with fewer moving parts, they’re easy to use, low-maintenance, and likely to last you years to come. And you can put away your ladder, too; since the sashes simply rest along a track, you can easily remove them for cleaning, any time!
Unlike their vertical counterparts, single and double slider windows fit into much wider openings, making them perfect to enjoy a mostly-unobstructed view while allowing plenty of airflow through your home. And with Dalmen Pro’s high standards for energy efficiency, you can rest assured that you’re making the smart investment for your home. Our Omni Series PVC frames and Optima Series PVC-aluminum hybrids are both designed to help regulate your home’s temperature, while triple-glazed low-E glass works around the clock to let light in without turning your favourite room into a sauna!

Window Package
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).
