Why to choose Secondary Double Glazing?
Simply, secondary double glazing is the choice to help you save money, save energy, save the planet and protect you from burglars.
Most plastic windows that are retro installed today are entry-level or minimum standard products. Most new house builders use similar but less expensive products. Bespoke new timber windows can be better warmth insulators than those plastic windows.
Top of range UPVC windows and purpose made joinery windows meet or exceed the minimum requirements of the current buildings regulations. They are on a level playing field when it comes to cost and quality.
How Effective Is Secondary Double Glazing?
Secondary double glazing is extremely effective both in terms of heat retention and noise rejection.
Our standard products can be bought on our online store. They reduce noise by around 20dBA across a broad range of frequencies. Heat retention capacity increases similarly – the existing ‘U’ value can be enhanced down to 1.6 if using our new hinged window with a 28 mm Argon filled Double Glazed Sealed Unit.
The consequential reduction in energy use saves you money and reduces your household’s carbon footprint.
The added security of SDG as standard, glazed with 4 mm toughened glass, deters house-breakers. If they do break the glass, the resulting gunshot noise will scare them off after waking you and the neighbours! Chance burglars, seeing Secondary Windows just pass on to somewhere else! Further security and sound-reducing glazing is an option.
So, you’ll decide to be more comfortable in your own home even if you buy one room at a time! We’ve told you about some types of glass – you can select further options later … 6.4 mm safety laminated, acoustic or low-E glass, 6.8 mm security or acoustic glazing, 4 mm and 6 mm low-E toughened glass and up to 10.8 mm complex laminated or specialist glasses. We do the common patterned glasses but not very often as usually the primary window has obscuring glass in a bathroom or shower.
