Energy Efficiency- Thermal performance.

We can advise you on the most energy efficient solution for your home. Our standard windows are A rated in energy efficiency, which will help you to save money on your energy bills at a time when prices are constantly rising. With the Energy Saving Trust estimating that up to 26% heat loss from homes is via poorly insulated windows, our A rated solutions easily justify our claims that they should be seen as an investment and not a cost.

And, if you want the optimum in energy efficiency, then we have a range of triple glazed windows available which are among the most efficient A Rated windows on the market in Northern Ireland.  

Frames & Glazing 

Frames are designed with multiple internal chambers within the profile system. Each chamber acts as a barrier against heat loss from inside the home and against cold air entering from outside, ensuring excellent thermal efficiency.

A++ Double and Triple Glazing Options-

Energy efficient glazing units feature energy reflecting glass as standard, which maximises heat gain by retaining interior warmth and transmitting solar energy from outside. Thermo spacer bars connect the glazing panes, helping to eliminate cold areas at the edge of the unit, reducing condensation.

Triple glazing 

U-Values 

U-values take into account all components of the window including the frame, glass and spacer bar; therefore the lower the U-value, the more energy efficient
the window.

Our double glazed windows offer U-values of 1.4 W/m2K as standard (‘A’ rating),

with the option to reduce the overall U-value to 1.2 W/m2K. By selecting the triple glazed windows, featuring Soft Coat Xtra and Argon gas, you can further reduce the whole window U-value to only 0.8 W/m2K. Camden windows are independently tested and certified, and exceed building regulation requirements for energy efficiency, which can be beneficial if renting or selling a property

Heat loss can be measured by either thermal transmittance or U-value. The lower the U-value, the better the thermal insulation. In 2006, Window Energy Ratings (or WERs) were introduced  for calculating the energy efficiency of different windows. Ratings are awarded from A+ to G, with an A+ rating indicating the highest levels of energy efficiency.

Current minimum building regulations require either ‘C’ rated windows or a ‘u’ value of 1.6 or lower. Make your home warmer by upgrading to an ‘A’ rated window or improve to a ‘u’ value. Windows play an integral role in creating an energy efficient home and situated in the right spot, they will help maintain a comfortable home, once installed our high-grade low emissivity windows will ensure your home stays cool in the summer and warm in the winter.

Saving you money on your energy bills by keeping the heat inside your home.
Up to 20 percent of the home’s heat can be lost through its windows, particularly if they are poorly installed or single glazed. Over time, this can result in a substantial increase in the cost of heating your home. Installing energy efficient windows, or making the home improvement for replacing the glass with double glazing is great decision.

The uPVC casement windows we offer come fitted with high-quality locking systems as a standard. They have passed the PAS 24:2012 Enhanced Security Performance, giving a high level of protection.

Tough, robust and durable. Inliten frames are fully welded, internally beaded and steel reinforced for maximum strength, and because they are made to measure, structural integrity. These windows also have the Secured by Design accreditation awarded by the Association of Chief Police Officers. This is only awarded to fittings that offer the highest security options.

Burglars usually gain entry to your home through a window or door. So you’re windows security is high on the agenda. it’s important for you to select windows with adequate locking devices. You also need to think about the window itself – the frame must be of high quality and able to withstand hard knocks.

Windows offers the Espagnolette locking system, an extremely robust multi-point lock that offers exceptional security. When locked, your door or window will bolt itself into the top of the frame and the floor, as well as at the handle, giving it even structural strength throughout. Any would-be burglars would have to attack the lock at all points to gain entrance, delaying their attempts until the alarm is raised.
