Secondary Glazing Windows

Replacing the glazing in a period property doesn’t happen often – and it deserves to be done right, using the proper glass. After WWII putting a hold on things, Haven’s ‘Thermopane’ product was finally put into production in 1952. It promptly became one of the most popular luxury products on the home market.

Everything you need to know about double glazing (we hope.) Double glazing is becoming, and in fact has become, the standard offering for glass upgrades in most homes around the country, and indeed the world. It offers plenty of additional benefits, making a home warmer, quieter, and more energy efficient. Double glazing as we know it today, however, was invented in 1930 in the USA, by C D Haven. His maverick designs involved two panes of glass, commercial Glazing equal in size and thickness, bonded into one single frame. This required perfect uniformity in the glass used, which was pretty expensive and impractical at the time. It wasn’t until 1941 that he even managed to secure a deal with a company willing to produce his innovative product.
If conventional double glazing is not possible, such as in a listed building or with stained-glass windows, secondary glazing is the ultimate solution for insulating your building. In our blog we use the term ‘secondary glazing’ for an extra window mounted on the inside of an existing window. This means you must make sure to check for proper adhesion with the latest window frame types (various types of PVC, foil or coated aluminium). Soudal takes care to stay up-to-date with these developments so as to be able to guarantee optimal adhesion.

Double glazing consists of two panes of glass separated by a vacuum or a layer of inert gas such as argon or krypton set in the same frame. The air gap reduces the thermal conductivity between the two panes, keeping the heat inside and the cold out. Many windows also come with Low-E (low emissivity) coatings on one of the glass surfaces, for improved thermal performance. Double-glazed windows have two panes of glass, separated with a layer of normal air or, for more efficiency, a layer of argon gas. The panes are then sealed to keep the gas contained, creating an airtight, sealed unit. To reduce noise and improve thermal insulation, secondary glazing offers an effective and affordable alternative to traditional Velux window installation replacement.

SealerA substance applied to glass and frame surfaces that guarantees consistent adhesion. Screen printed glassScreen printed glass is tempered or heat-strengthened glass, one face of which is covered, either partially or totally, with mineral pigments.
