Perfect for both modern and traditional properties…
This ULTRA-sleek window is ideal for both modern and traditional properties. Depending on the style and size, as much as 12% more light can be gained by installing our Slim-Jim windows, compared to other typical uPVC windows.
Our expertly engineered Slim-Jim Windows are designed to fit within any typical British home.
Its aesthetic slim design ensures that your replacement-new windows will enhance the look of your property, rather than detract from its overall appearance that sometimes happens with typical thicker framed uPVC windows.
Our “slim-Jim window is often chosen by our customers originally looking for aluminium windows due to its ultra slim frame and the fact that like aluminium is available in a full range of colours, BUT less expensive..!
As with every project we undertake, our team of glass and glazing experts are on hand to help you design a bespoke window to suit your property’s style.
We can tailor your new Slim-Jim windows to create either a modern or established look. Our exclusive Slim-Jim windows are also available in a whole range of colours to suit any property.
Our Slim-Jim windows are extremely energy efficient, and have been awarded an energy index rating of ‘A+’.
Its impressive energy rating guarantees that your home stays warm and dry all year round, and in the process, helps to cut the cost of your household bills.
Your new Slim-Jim windows will be completely draught proof and watertight. The Slim-Jim profile is produced with all weather bubble gaskets (seals), fused to both the inner and outer frame section.
The bubble gaskets are hollow and offer greater compression and remain in-line with the profile for a neater appearance. They are fused to the profile, which means they can never shrink back, reducing the chance of leaks or unpleasant draughts in your home.
Naturally, you want to be assured that the quality of the installation will match the quality of the products. As a CERTASS registered company we work with an agreed code of practice, which includes a full understanding of the building regulations and the other CERTASS requirements.
Prior to your installation, a full and accurate survey will be carried out. The survey will ensure that your desired style of window will combine effectively with your home.
