Replacement windows and doors

Product Information / Technical Specification

uPVC

There are many profiles of uPVC on the market which, when installed, can seem very similar.  Profiles are made up of uPVC (unplasticised polyvinyl chloride) and cavities, which reduce the heat loss through the frames.  The more cavities the profile has (and therefore the thicker the profile), the more efficient it is at reducing heat loss.  Similarly, the narrower the frame, ie fewer cavities, the poorer the insulation factor.

Whilst we are not tied to any one manufacturer or profile, and can supply and install any profile on the market, including Halo, Profile 22, Rehau and Eurocell, we have chosen one in particular as our primary product.   This is the Duraflex profile, 70mm in width, and combines function, form and aesthetic appeal into one.

The Duraflex:

• Has a superior 8 multi-point locking mechanism for optimum security, with police 'security by design' accreditation
• Has a strong aesthestic appeal
• Is manufactured well, using for example good length screws on the locks and keeps which won't easily come out when forced
• Has simultaneously fully welded frames which provide increased structural strength, and is re-inforced with galvanised steel for further maximum strength
• Is tested and compliant with the BFRC window energy ratings
• Is manufactured to the stringent BS7950 security standard and complies to the BS7412 standard for weather resistance and draught proofing

In addition it fits well with an excellent internal beading system, good for us as it is great to fit, and good for you as it prevents the glass from being removed from the outside, thereby providing added security; and it incorporates a night vent facility to allow ventilation whilst still maintaining a locked and secure unit.

Timber

Our standard Timber products are supplied by Dempsey Dyer. All Dempsey Dyer products are gasket glazed, with either sloped or concealed drainage systems, and incorporate security tape, friction stays and espagnolette locking as standard. A range of cill, frame thickness, finish and ironmongery options are available. We supply high quality hardwood and softwood timber products based on a high quality design. The beauty of timber is unsurpassable and if looked after will last for many generations.

Aluminium

Aluminium is naturally stronger and much more stable than other materials commonly used for windows and doors. They will not warp, rust or need painting and are particularly suitable for bay windows, doors and conservatories, where extremely strong sections are essential. Our aluminium profile is protected by a tough and resilient powder paint coating or hard anodised surface. Both finishes will give you years of excellent service with only the minimum amount of maintenance.

Energy Efficiency

Replacing your windows with energy efficient windows can save money and reduce your carbon footprint.  Old and single glazed windows can be a major source of heat loss in the winter, which increases the carbon footprint of the property and increases heating costs.

The British Fenestration Rating Council Limited (BFRC) window rating system has been developed to address this problem and allows you to compare the energy efficiency of different products.  Windows are currently rated from A to C, with A being the  most energy efficient.  All Eclipse windows have been tested and comply with the BFRC Window Energy Ratings A to C, when the correct double glazed unit is incorporated into the frame.

Changes to the Building Regulations in October 2010, mean all replacement windows must now have an A, B or C energy rating.  The ratings are similar to those you’ll see when buying white goods. In this case, they indicate the combined energy efficiency of the frames and glazing. The higher the rating, the better the window at reducing heat loss.

How your window’s energy rating is calculated:

Energy efficient windows allow the sun’s energy to pass through the glass allowing the warmth of the sun to heat your home. At the same time, a glass coating reflects heat on the inside back into the room rather than allowing it to escape.

Energy ratings can be increased with argon-filled glass units and warm edge spacer bars (the bar which holds the two panes of glass apart). These slow the transfer of heat from the inner pane to the outer pane.
