Windows and Doors

Over time, the seal to a double glazed window will fail, causing moisture to make its way in between the two panes of glass. This is what causes your sealed unit to look foggy or cloudy. When this happens, give us a call and we will come take a look to give you a quote. Alternatively, if you already have an idea on sizing of the window, fill out the form on our site and we will gladly e-mail or call you with ball-park pricing. RPM will also supply and install broken or cracked single glazed windows. For single pane replacement, we typically cut this glass to size on-site and will install the very same day. Throughout every step of our window replacement process, from initial inquiry to cleaning up after the installation, it is our priority to offer you exceptional window quality, competitive prices as well as the first-class customer service. Our competitive prices, first class customer service and a strict window replacement process make us one of Ottawa’s leading window manufacturers and installation outfits.

types of single glazed glass

Although most single paned windows are 3mm (1/8”) clear glass, some may have textured glass – especially if you are in an older home. Since there are so many different patterns/textures to choose from, we recommend that if you are trying to match an existing piece to take a photo and e-mail it to us (or bring it by our shop) – we will do our best to match it! If you’re not sure which type of patterned glass you’d like, stop by the show room and we will show you samples. To read

types of sealed units

A sealed unit will usually be made with two pieces of 3mm (1/8”) glass with a ½” airspace between the two panes. As you may have already noticed while reading through our website, nothing in the glass industry is typical or standard. Like most other applications, sealed units come in different types including:

low e / argon

Tinted for climate control or privacy.

laminated for security and/or sound proofing

The thickness of glass and air space can vary depending on the application. Call us today to set up an on-site consultation. You can check out our portfolio to see examples.

switching from single glazed to double

Most older homes still have single paned windows, and you may benefit from removing those single panes and install new and efficient windows. Some questions to ask yourself when considering this change would be:

when do i need an upgrade/replacement

Am I noticing a lot of street noise such as traffic, sirens, foot traffic, etc.?
Is there a draft coming from my windows?
Are my single paned windows looking dingy and outdated?
New windows can be very energy efficient and even help with keeping your home warm in the winter months and cooler in the summer months. In some instances, windows can be converted from single to double glaze.

Your existing windows may be:
Older windows are often single glazed and non-thermally broken (metal from inside to outside). They offer minimal insulating value and allow energy to transfer easily. Aging, outdated seals and gaskets can also contribute to air flow and increased heat loss.
Poor insulation also allows the passage of sound waves. Noise pollution can be annoying and distracting and may even affect sleep patterns.
Windows are a defining element of any building. Old windows may reduce “street appeal”.
Small leaks and the resulting damage may not be obvious but can lead to serious problems and ever increasing repair bills.
Your new windows will:
Energy-efficient windows reduce cold drafts and make units feel warmer during the heating season.
The interior surfaces of energy-efficient windows stay warmer, which means you can maintain a higher level of relative humidity without worrying about condensation on the windows (keep in mind that efficiency improvements to windows will not prevent condensation if the humidity level inside is too high).
Minimizing air leakage and improving the thermal performance of your windows. All our Windows Vinyl windows are Energy Star Zone rated B or better.
Condensation can cause premature deterioration of windows, as well as walls and finishes, leading to costly maintenance or replacement.
Promote a healthy living environment. By reducing condensation, energy- efficient windows help prevent mold growth.
Nothing provides greater street appeal and lasting investment than new windows
