Energy Efficiency
Windows and doors can account for up to 25% of the total energy lost from your home.
​
Having them replaced will not only save you money, but reduce carbon emissions and the impact on the
environment.
Benefits
Reduced heat loss
Lower energy bills
Quieter living space
Greater all-round comfort
Energy Ratings
Window and door energy ratings are a clear and obvious way of determining their efficiency. They identify how good the products are at:
• Keeping out draughts
• Adding warmth through solar-gain
• Preventing heat loss
There are two ways of rating energy efficiency; energy ratings and u.values
Energy Ratings
The British Fenestration Rating Council (BFRC) uses a scale of A++, which is the highest total energy-efficiency rating, to E, which is the lowest.
U-Values
A U-value is a unit of measurement, in W/m2K, used to measure the transference of heat through a structure.
It’s used to determine how quickly heat can escape through a material. The lower the U-value of a material, the slower the heat will transmit through the material, meaning the material has high thermal insulation properties.
Our profile 22 uPVC standard double glazed windows are A rated, with a u.value of 1.3
​


Our profile 22 uPVC standard triple glazed windows are A+ rated, with a u.value of 1.0
Section Title
Glass is an important factor in defining the energy
performance of your new windows and doors.
All the double and triple-glazed glass units
we supply use smart low-emissivity (low-e) coatings
to trap and hold energy.
We also use warm-edge spacer bars, which separate
the sheets of glass in double and triple-glazed units to
put distance between the cold air outside and warm
air inside.
​
This cavity is filled with argon, a gas denser than air
which creates a highly effective insulating barrier,
helping to keep your home cosy and warm in the
winter months.


Our window frames feature five internal chambers
in the sash and six in the outer frame. This thermally
efficient ‘honeycomb’ creates a series of barriers to
conserve heat.
When it comes to replacing your windows, the glass you choose can make a big difference
​
We always advise to think about your needs for each room, as each home is different.
​
We have three glass offerings available, which make it easy when matching to your needs......

A special coating on the glass helps stop heat escaping, so you’ll use less energy to keep your home warm.
​
The high-security transparent layer makes the glass much tougher to break through than standard, unlaminated glass. Used in an approved window frame, they’re designed to meet the official police security initiative ‘Secured by Design’ standard.
A built-in acoustic layer helps keep exterior noise exactly where it belongs –outside. If you live on a busy road or close to other disturbing sounds, noise control glazing should be on your list.
Prolonged exposure to ultra-violet light from the sun will contribute to your furniture and curtains fading over time. A hidden layer of protection on the glass blocks out 99% of the sun’s UV rays.
Rooms with lots of glass will give you a great view, but the warmth from natural daylight can make it uncomfortably hot on sunny days. A special coating can be added, designed to keep out heat from the sun’s rays. It’s particularly suited to south- and west-facing rooms with sunny aspects, or larger glazed areas such as bi-fold and patio doors.
