Patio Door Test Wall – A Valuable Investment in Quality

Have you ever wondered how patio door manufacturers test and perform quality control on their products? Well, the more sophisticated ones deploy what’s commonly referred to as a test wall.  A test wall is a high-tech and expensive piece of equipment. One expressly designed for simulating how the patio door will stand up to different weather conditions. Test Wall Benefits At Sunview Patio Doors, we constructed the test wall pictured here several months ago. As a result, we have been able to see first-hand, how our doors will perform in real-life situations. Water Resistance There are three primary functions served by the test wall. The first has to do with water resistance. This particular test wall has 240 high-pressure spray nozzles that can simulate a severe storm with horizontally driving rain. By running these tests, we can tell if water is seeping through the seals on the top and sides of the door. Also, we can assess water issues from the seal at the bottom. It reassures us that our doors have been optimally assembled and that the seals are at the level of quality we expect. Air Infiltration The second variable tested with the wall is air infiltration.   The test accurately measures the amount of air leaking through a door at a designated wind speed.  Air resistance is an important part of the energy equation when measuring the efficiency of a patio door. More importantly, it will help with heating and cooling bills. High-Wind Impact Finally, we use another process that simulates the effect of high winds.  These tests allow us to measure how the door behaves in extreme wind conditions.  This test is...

Corner Key Technology Provides Unmatched Strength and Durability

Corner welds are often critical stress points when manufacturing premium patio doors. Corners are especially important considerations for heavier products in high-use environments. Therefore, to optimally reinforce its door corners, Sunview uses unique “Corner Key” technology imported from Italy. Since Sunview’s exclusive Corner Keys are custom-designed from high-grade aluminum, they will prevent doors from ever sagging or shifting. Sunview Corner Key Technology Sunview Corner Keys are engineered to exacting specifications. And, they are precisely aligned and securely tightened during the manufacturing process. This two-step attention to detail ensures 100% angle accuracy throughout the life of the product. As a result, doors with Corner Keys will have significanty improved durability and strength for decades. Also, since we use aluminum, there is very little weight added to the door. Monticelli is Sunview’s partner in the process. They are a world leader in the manufacturing of corner brackets and accessories for doors and windows. It is the only company which deals with corner joints from the designing stage to development. “Ortelles” is the name of the Corner Key built for Sunview, and they are the first aluminum corner joints engineered to fit perfectly within PVC profiles. Also, tightening two additional aluminum profiles into the central hollow after the traditional weld further strengthens the Corner Keys. The Corner Key is one of the many innovations incorporated into Sunview patio doors. It sits unseen inside each corner of Sunview’s Essex Swing Doors and  Muskoka Folding Glass Wall Systems. This unsung hero will keep these premium doors straight and true in all weather conditions and through constant use. Take a look at the video to see how the...
