Some of our regular customers (Platinum Associate, Bridge Academy-Hackney, L&Q, Ellis & Co, …etc) rely on our professional glazing services in case of any glazing issues on their buildings. Double glazing sounds easy and looks easy, but it is a special area, which requires adequate knowledge about the glazing and frame system (PVCu windows or doors, aluminium frame system /Schuco, Sieger/ curtain wall system, Crittall style windows, casement windows, bespoke steel, wooden or aluminium windows and doors, composite doors and windows …etc). Our professionals have more than a decade experience in these glazing systems and their characteristic. We undertake all parts of any double glazing unit replacement or installation projects from the initial survey, when our engineer takes accurate measurement about all dimensions of the required double glazed unit (thickness of the glasses, lamination, air-gap, …etc), manufacturing the new glass unit, managing the delivery and lifting operation if necessary, and install or replace it professionally. Our manufacturers provide safety glass, security glass, laminated glass, fire rated glass (fire safety glass), heat stop and sun reflective glass in any colour and dimensions or frosted glass units for keep your privacy on the highest level. Double or triple glazed units can have a wide range of fire rating (30min – 60min), heat insulation efficiency and noise cancellation characteristic which can be specify the cost of the glass unit. We can manage any double glazed unit (sealed unit) and organise the installation or replacement process.

Misted / blown double glazed unit, double glazing

The most common issue is when the double glazing in a window or a door is getting to be misted or foggy / blown inside, between the two layers of glass, which can destroy the view through the window and the appearance of the room from inside and the building from outside. However the main issue is that these misted (blown) double glazed units loose their heat insulation ability completely, which can highly affect the energy efficiency of the property. Mist (condensation) can appear in the double glazing when the sealing (hot melt sealant usually) on the perimeters of the glass unit detached from the glass surface and let the air and its humidity in. As the general air humidity is getting in a trap inside the blown double glazing, this humidity condenses on the surfaces and became mist / fog, generated by the difference of the rapidly changing temperature between the two glasses. This excess “water” condensation generates bigger and bigger gap between the two glasses and more and more fog and mist on the surfaces. These misted double glazed units must be taken off for any further measures. Repairing these misted / foggy or blown double glazed units in situ, in the frame is not possible, so the replacement of the faulty blown double glazed unit can mean resolution for this awkward situation only. If some glass parts of the double glazed unit is worthy (coloured, fire rated, toughened, …etc), then it can be salvaged and used for the new unit. In this case we can replace the unit temporarily, with temporary materials, using a plywood or transparent polycarbonate sheet but it means some extra cost in the process. We can offer the best prices and the most efficient double glass replacement service in London, provided a like for like, or any bespoke or redesigned double glazed (sealed) unit.

Double glazed unit (DGU) repairs

Repairing double glazed units in situ, in the frame is not possible or do that in the workshop is not cost effective. The replacement glass unit means the only acceptable and cost effective solution for this issue which can be managed quickly, depending on the leading time of the manufacturing.

Double glazed unit (DGU) replacement

Double glazed unit replacement or any glazing work on site is a complex undertaking. Our professional services covers the initial site visit and survey, when our engineer can collect all information, take accurate measurement about the damaged double glazed unit, specify all details of the new glass unit, manufacturing and delivery, and the replacement of the double glazed unit on site. Double glazed unit replacement is coming up, when the glass is damaged, cracked, shattered or misted. These issues can be caused by the age of the double glazed unit, some mechanical impact, wrong installation manner, constant movement in the frame (wrong fixing) or just a simple material/manufacturing issue, a so called Nickel Sulphide Inclusion (NSI) in the toughened glass part, when the glass shatters to a million small particles (toughened / tempered safety glass) without any mechanical impact or previous sign. We can manage any DGU double glazed unit replacement, no matter that the glass is accessible from inside the building or it requires special external access (rope access / abseiling) solutions.

Double glazing

Double glazing is the most common glazing solution in our modern world. Its safety, energy efficiency, cost, easy manufacturing and installation process make this type of glazing really popular and widely demanded and accepted. Double glazing is far more complicated than it sound in the first instance. The thickness of the glass layers, types of the glasses in the unit (toughened, laminated, safety, fire rated glass, …etc) sun reflection coatings, thickness of the airgap and the gasses filled in the “airgap” make the double glazed unit and its characteristics really various. Of course, the price of the double glazing is proportional with these characteristics, but eventually the most simple and cheapest double glazed unit has far better energy efficiency than any single floated glass (pane). There are some basic building and safety regulations about the double glazing generally, which can help to keep the minimum standards and safety.

Double glazing energy efficiency

The energy efficiency of any double glazing shows far better values than any traditional single glass (pane). The energy efficiency of the double glazing depends on the thickness of the glasses and the “airgap”, the gas filled in the “airgap”, the coatings (sun reflection or heat stop coatings), the situation and overall size of the glass unit. The most basic information about the energy efficiency rates is available on the British Fenestration Rating Council (BFRC) website and it can give you directions for the best choice and actual regulations. Any external door or windows made and fitted with (at least) double glazing, these are the double glazed windows and doors. It can be just better the triple glazing and triple glazed windows and doors (see below).

Triple glazing

The most basic difference between double glazing and triple glazing is the main characteristics of these glass units, such as energy efficiency and noise cancellation. Triple glazing has far better energy efficiency rate and noise cancellation characteristics on the basic level than any other double glazing. Triple glazing has two “airgaps” whilst double glazing has one “airgap”, which means 50% – 80% better energy efficiency. As the tree layer glass, their various thickness and types of the glasses in one unit can break the waves of the sound, reduce the vibration and change the resonance between the layers, triple glazing has a really good noise cancellation characteristic. Triple glazing is the next stage in the fenestration industry. Despite these good characteristics of triple glazing, its price pushes this solution to the background in general usage.

Triple glazing energy efficiency

The energy efficiency rate of any triple glazing far exceeds of any single floated glass, double glazing or other structural glazing. Triple glazing is used for luxury apartments and buildings, passive houses, and highly rated green houses, where the cost of this solution is calculable as value and/or a long term investment to achieve the highest rate of energy efficiency. Triple glazing means tree layer of glass and two airgaps, which cannot be beaten in energy efficiency, especially if it’s been coated with a special heat stop solution.

Double glazing replacement on atrium glazing and conservatories

Our specialist team undertakes any atrium glass replacement and conservatory glazing works. Double glazing is widely used for atrium glazing and conservatories.

Double glazing vs secondary glazing

Double glazing is a far more efficient, cost effective and comfortable solution like any secondary glazing to safe energy, prevent the internal areas of the flat form the cold and condensation on the windows and glass surfaces, which affects negatively the comfort and human health. Sometimes, when the window or glass replacement (swap to double glazing) is not possible (heritage buildings, budget, …etc) then London Glazing Repairs provides the best prices and most professional service to install or repair secondary glazing.

Nickel Sulphide Inclusion

Nickel Sulphide Inclusion is the most common issue when the external layer (usually) of a double glazed unit made from a toughened glass. The tempering process of the tempered / toughened glass can concentrate some elements (iron) and chemicals ( Nickel Sulphide) in some certain spots in the glass pane, which makes the toughened glass really vulnerable against quick heat expansion or shrinking, when the glass is shattering without any previous sign or mechanical impact. Replacing these shattered glass units, especially on the high level of the building requires special skills, equipment and a professional team. We can provide “low iron glass” and “heat soak tested (HST)” glass in these cases, but it can slightly increase the leading time and the final cost of the project.
