RAL Coloured PVCu Windows and Doors
RAL Coloured PVCu Windows and Doors

L F Replacement Windows take advantage of the ‘deuctone decoroc‘ in-house process that Deceuninck offer. Dating back over 22 years, this patented finish structurally bonds to the UPVC and crucially is applied at bar length stage before the insertion of gaskets. This means, obviously, that there is no chance of over spray onto gaskets which can happen when pre-assembled frames are sprayed.

The other fundamental benefit of the product is that it is done in-house by the systems company, Deceuninck, and therefore comes complete with a full warranty of at least 10 years on both the finish and the profile. Several RAL Colours are available. 

The beauty of the deuctone decoroc finish is that it is proven. It has been around for 22 years which for anyones money is the longest any colour UPVC finish has been in existence for. This gives all in the supply chain piece of mind that the product will be there to stay especially when extended warrenties are becoming more common…

Vertical Sliders
Vertical Sliders

Our vertical sliding windows offers improved fire safety because, at the touch of a button, the sashes can be quickly folded inwards and down on top of each other.

This helps the window comply with general provisions outlined in Building Regulations Part B (Fire safety) - as long as a window has an unobstructed opening area that is at least 0.33m2, 450mm high and 450mm wide, it is deemed sufficient as a means of escape in the event of a fire.

LF Replacement Windows preferred Deceuninck vertical slider because it offers superior aesthetics compared to other systems on the market.

This is created by a combination of slimmer sightlines and attention to detail on styling, such as decorative horns and decorative glazing beads. This was important for the company as it will be fitting the window in many distinctive and architecturally significant properties.

It captures the stylish look of the Georgian era, combined with the low maintenance and energy efficiency benefits of PVC-u.

The slide-and-tilt mechanism also allows access to the outer panes, making them easy to clean and maintain from inside a building.

We are finding that vertical sliders windows are used primarily in property where the original wooden windows where vertical sliding sash windows.

Deceunick supplies the vertical sliding system in white colour.

Secondary Glazing
Secondary Glazing

Secondary glazing is a good second choice when external double glazing is not “allowed” as your first choice because of the current UK planning restrictions.

Secondary glazing to match your existing window configurations as far as possible is available, as has been designed to be as unobtrusive as possible.

Consequently, L F Replacement Windows supply and fit secondary glazed window systems that are horizontal sliding, vertical sliding, side hinged, lift out, fixed, butt hinged, lift in, clip out or combination units (i.e. side hinged and lift out secondary glazed window systems). Also available is a heavy duty double glazed secondary glazed window system, where noise and/or heat loss is a particular problem and added insulation for a particular property is needed.

More Benifits for Secondary Glazing

Ideal if you can not afford high quality double glazing, particularly in built up urban areas where traffic noise is a nuisance, or indeed if standard double glazing has been fitted and the disturbances persist.

Secondary glazing can be installed in listed properties and properties within conservation areas where restrictions prevent the modification of the old existing external windows.

Secondary glazing can be a cost effective alternative to replacing your existing single glazed windows, for example in leasehold properties where changing the existing windows may be uneconomical.

Secondary glazing can be fitted to any window that needs noise reduction and/or draught reduction, where other glazing options not viable or practical.

One major benefit of tilt back vertical sliding secondary glazing is that it is ideal for cleaning, as both the back of the glass and the existing window can be easily cleaned.

In environments with extreme noise disruption where high spec glass is insufficient to cope, there is a heavy duty system that can take a double glazed unit.

This is available as horizontal or vertical sliding secondary glazing.  Click Here to Download Brochure
