Thermal Efficient Replacement Doors 

Double Glazed uPVC Window Manufacturers

At SDL Windows bases in Stoke-on-Trent we take pride in the levels of service and quality in the products that we supply. Replacing old windows and doors for new quality Double Glazing, and Composite Doors can offers many hidden benefits to home owner’s, not just in the look, but also in the design and security. New Double Glazed Windows, and Composite front Doors offer home owners advantages such as thermal efficiency, reduced external sound, the reduction or even removal of condensation, and not let’s forget the added security.

Security

Installing extra secuirty to your home

Security is a paramount importance in homes today, installing upvc windows with deadlock, shoot-bolts and composite keeps can significantly improve your homes vulnerability.

Unfortunately the topic of security has to take pole position as to the benefits of replacing your windows and composite doors. All our double glazed windows have security casement shoot-bolts where a window opener is required. These lock types stop intruders from prying open the window casements in order to gain entry. The security can also be improved by requesting the glass units to be laminated, so even if the unwanted guest breaks the glass, they would still have to get through the tough laminated film. Our composite Doors security is also second to none. All doors can be supplied with a Police Accredited Certificate, (Secured By Design). The manufacturers are so confident of the high levels of security the these Composite Doors offer, that they Guarantee to pay £500 if your door is broken in and supply you with a brand new Replacement door. Now that’s confidence on a different scale. We also offer a bespoke range of  Fire Doors with 30 minute ratings.

Thermal Efficiency

All Our Replacement Double Glazed Windows are Supplied and Fitted A Rated as standard

Double Glazed Windows will reduce the heat loss from your home, all our double glazed windows are filled with argon gas to upgrade their thermal efficiency

Complex manufactured composite doors and double glazing have great thermal efficiency values as there are either two panes of glass in the glazed units, or the compound doors slab is made from highly thermal efficient materials. The two panes of glass in a double glazed unit from alliance products are filled with a Argon Gas, this added extra at no additional cost greatly improves the units rating, which is why all our windows are A Rated as standard. Using this technique, it is very difficult for different temperatures leave through the glass, this keeps your home warmer in the winter and cooler in the summer. These added benefits help to reduce your fuel bills in both summer and winter, and also reduce your homes carbon foot print.

Reduced Sound

sound reducing upvc windows

The image above shows how better noise is reduced when upvc double glazing is installed into a home

Follow the installation of your new Double Glazed Windows or  Door, you will be unable to notice the reduction is sound from single glazed units and wooden doors. Again the double panes of glass or with the complex door slabs materials, these both reduce sound levels greatly, but if you are looking to get the greatest of sound reduction, then we can supply the glass in both windows and doors which have a lamination film on the inner sides of the units. These laminated units have the best values for noise reductions and also offer fantastic security improvement.

Condensation Reduction and Removal

The reason why many homes suffer from condensation is due to a naturally occurring event, this is when warm and cold air meet, the moisture in the air then condenses at the meeting place (your old window panes). This can cause mould and unsightly black and green patched on your walls and windows. The Double Glazed Windows that we install are A rated, which means that a thermally efficient barrier is in place, not only in the glass as mentioned above but also in the design of the window casements, with these improvements and if required trickle vents, your home can be condensation free.
