Secondary Glazing for Heat Insulation
Our
standard range of Secondary Glazing provides very good Heat Insulation.
To put this into perspective, the heat insulation of a window is expressed as
the U Value - the lowest U Values provide the best insulation.
- A single glazed metal window will typically have a U Value of 5.7
- A single glazed timber window will typically have a U Value of
4.8
- A double glazed timber or PVC window will have a U Value
of between 2.7 & 1.8, depending upon the depth of cavity, the glass
type/s & whether the cavity is air or argon filled.
Building Regulations for Replacement Windows set a U Value of 2.0
for Residential & 2.2 for Commercial.
Our standard 4mm Float
Glass Secondary Glazing over an average single glazed window achieves a U Value
of 2.5
Our Secondary Glazing with a 4mm Thermal (Pilkington K
Glass™) Low E Hard Coat Glass will typically achieve a U Value of 1.9
- better than the Standards set for Replacement Windows.
Secondary
Glazing is Ugly & Obtrusive
Not True. Our Systems have been Designed to
be effective, stylish & discreet - they are nothing like the sort
of thing that you may have seen elsewhere or in years past.
Additionally,
we put as much emphasis on achieving an Unobtrusive Installation as we do on achieving
Optimum Heat Insulation.
Suitability
Our extensive range
of Secondary Glazing is suitable for installation to virtually any type of primary
window or door in both Residential & Commercial properties.
We have
fitted it in flats, houses, offices, Listed & Period properties, hotels, churches,
public sector buildings, etc.
