Devon by CertainTeed Thermal Vinyl Replacement Windows

Devon windows are manufactured from Certavin#153;, CertainTeed's exclusive vinyl formulation. They can stand up to a lifetime of harsh exposure without corroding, peeling, chipping, or flaking.

Double-hung sashes tilt in, sliders lift out, and casements open 90º for easy cleaning from inside your home.

The features that perform -- day after day, decade after decade.

Rough handling. Tough environments. Devon windows have seen it all. And survived beautifully.

That means you can install them and forget them. Your family can use them year in and year out, without a worry.

High-strength fusion-welded sashes and mechanically fastened frames are strong and structurally sound. They can stand up to pressures that make other windows shift, bend, or collapse.

And every detail has been refined. Custom-designed hardware is made from non-corrosive metals or UV-stabilized engineered plastics for long life. The balance and the tilt-in mechanisms for the sashes are corrosion-resistant and tested for decades of trouble-free operation.

There's virtually no maintenance required to keep your Devon windows looking great. Their solid vinyl construction means no scraping, puttying, or painting. In fact, just a quick wash with soap and water will make sashes and frames look like new.

Pro Windows and Siding are experts in the installation of this exquisite premium siding.

For truly easy sash operation, CertainTeed's balance operates like a high-quality retractable tape measure -- with a smooth, steady pull.

Why your windows will operate easily -- always!

The balance system makes the difference in how well your windows operate.

Ordinary systems, like block-and-tackle or spiral balances, are based on simple wire-spiral springs. You've played with springs like these -- the farther you stretch them the harder they pull back. You can feel that when you open and close most windows.

CertainTeed's balance system is different. It's based on a ¾" wide stainless steel coil that applies a constant force. There's no change in tension, so sashes are easy to open and close, and stay where you put them.

Relax and stay comfortable -- whatever the weather.

You can trust Devon windows to resist air and water infiltration. They've been tested in the laboratory and proven in the real world -- even during severe storms.

From the storms and snows of the northern states to the heat and hurricanes of the southern coasts, Devon windows have met the test. So you don't have to worry.

A comfortable home.

They even block outside noise, with a sound transmission coefficient (STC) that's better than a 4-inch cinder block wall.

Real thermal efficiency

For optimum performance choose CertainTeed's proprietary Thermaflect® glazing system with Low "E" glass, and argon gas (which increases the insulation value of the double-pane unit).

Thermaflect's special coating of two microscopic layers of silver -- versus one on ordinary Low "E" -- gives it additional selectivity. Thermaflect not only keeps heat inside in cool weather, it keeps out the sun's heat in warm weather two times better than ordinary Low"E". It does all this while blocking 87% of the UV rays that can damage fabrics and carpets, and letting in high levels of visible light for a natural view.

In Winter and Summer, Thermaflect will help keep you more comfortable, and help reduce energy costs.

Cross section of sash and sill

How advanced engineering beats the worst weather.

Air spaces in the sash and frame (1) and double wall profiles (2) add insulation and strength.

Double-pane insulating glass unit (3) with a low-conductance spacer (4) is far superior to single-pane windows; glass is bonded to sash (5) and made weather-tight with a rigid glazing bead featuring a flexible lip (6).

A sloped sill (7), a rubber gasket seal (8), and silicone treated, high-density-pile double weatherstripping with a mylar fin (9) help keep your home draft-free.
