Energy Efficient Windows & Doors

Carlson specialize in energy efficient windows and doors with low u-Values. All our products exceed Irish & UK Building Regulations and Standards.

ENERGY SAVING

Energy-efficient windows and doors play a key role in reducing heat loss, lowering heating bills, and improving year-round comfort. Choosing high-performance replacement windows is one of the most effective ways to enhance your home’s energy efficiency and reduce its environmental impact.

The Environment

From an environmental perspective, one of the most important functions of a window is its ability to retain indoor heat and minimise energy loss.

Carlson’s climate-smart windows and doors are designed with sustainability at their core—manufactured in line with our environmental policy and focused on long-term energy conservation. Energy conservation is a top priority for all Carlson windows and doors.

ENERGY EFFICIENT GLASS

Every element of our windows and doors is engineered to perform in even the harshest weather conditions. As standard, our double and triple glazed units feature Low-E Argon-filled glass and warm edge spacer bars, ensuring excellent thermal insulation and energy efficiency.

Low ‘E’ Glass

Carlson uses Low ‘E’ glass on all our products. Low ‘E’ stands for “Low Emissivity”. A microscopically thin invisible layer of metallic film is coated on the inner face of the outer pane of glass. This allows sunlight (heat) to enter through the glass, while significantly reducing any heat loss from the room.

Argon Filled Energy Glass

Carlson uses “Argon Filled” Energy Glass as standard in all products. This provides additional insulation in our Double & Triple Glazed Units.

Warm Edge Technology

Warm Edge Spacer Bars come as standard in all our Window and Door products. They provide improved insulation and help prevent internal condensation by eliminating the cold bridge effect at the edge of the glass.

HOW DO I KNOW IF A WINDOW IS ENERGY EFFICIENT?

In order to measure the energy efficiency of a Window, there are different ratings.

 

U-Value Ratings

Simply put, U-Value ratings indicate how energy efficient a window or door is, in other words how well it keeps heat inside your home.

U-Value is a measure of the total heat flow through a window or door, from the air inside the room to the air outside. The lower the number, the better the insulation.

G-Value Ratings

However, other factors such as G-Value also come into play. Also known as Solar Heat Gain, G-Values are a measure of the free radiant heat that enters your home through the glass.

This can also be a consideration when choosing high performance Windows & Doors.

Double Glazing

All our products are available in energy efficient Double Glazing.

Our Timber windows and doors are manufactured from high quality Scandinavian pine – an excellent insulator.

Our AluClad windows are the same as our Timber Range, with a maintenance free aluminium cladding added to the exterior.

Triple Glazing

Our Timber & Alu-Clad Ranges are also available in Triple Glazing, which provides additional insulation and acoustic ratings.

Triple Glazing can be ideal for well insulated, energy efficient homes and/or where noise is an issue, such as busy roads, rail lines, airports etc.

Carlson U-Value Ratings

Carlson are continually improving our u-Value Ratings through research and development to ensure our windows and doors are as energy efficient as possible so you save money on your utility bills.

U-Value ratings indicate how energy efficient a window or door is.  The lower the number, the better the insulation.

What Our Customer’s Say

“Am I happy with Carlson windows and doors?  Absolutely!  Being a bit of a nerd, I spent a long time researching the available scientific data on heat retention, costs, benefits, testimonials with a questioning attitude and a dash of skepticism.

The final decision was made when I spoke to two home owners with personal experience of Carlson, and saw for myself the finished product years after installation.  I was very impressed by the knowledgeable salesman, no pressure tactics, just answered our questions in a straightforward manner.  He didn’t over-promise, but his colleagues certainly delivered, on time, on budget and with minimal disruption to our busy family.

The team doing the installation, took an obvious pride in their work and the company they work for.  I enjoyed several mugs of tea with the team; they were clean, tidy, hard-working, reliable, efficient, unobtrusive and professional.

A year later, I am delighted I chose Carlson, perhaps not the cheapest, but you get what you pay for.  I would be delighted to talk to any potential customers, and no I’m getting nothing for this testimonial.”

Brendan, Mount Merrion
