New Aluminium Casement Windows for Your Next Installation

It’s more apparent than ever to become more energy efficient, especially in homes. With the government introducing more regulations on thermal practicality, our team at D&I want to promote our windows. Aluminium casement windows are believed to be one of the most energy efficient models in the home improvement industry; aluminium material is known to be the most durable. With each material combined, we can create a thermal barrier like never before.

Living in the UK, we know the unpredictable weather conditions. Cold draughts and condensation can be unbearable; get in touch with our team and choose the best materials for your new home renovation. Keep your Wakefield property warm and dry when choosing aluminium casement windows in either top or side hung styles.

D&I offers competitive prices for top quality products, and we are always happy to answer any questions or queries that you may have.

Tight Corners

We are proud to promote Sheerline’s state-of-the-art craftsmanship, meaning that each screw is placed inside the mitre joints, creating the perfect 90 degree angles without any protrusions. Our aluminium casement windows are ideal for refurbishing due to their adjustability.

These corners are so special that they seal the glass in to create a ‘beadless’ window, making it more difficult for intruders to remove the glass. Have a secure, perfected solution with our aluminium casement windows.

Ultra Secure

A key aspect of a good window is its security. Our team ensure that we have a multipoint locking system available to provide your home and loved ones with the newest materials and strongest locks.

These aluminium casement windows are made with extra space within the frame to ease the installation of these locking systems. The locks will never protrude from the frame or ruin the incredible sightlines of the window. Instead, you will receive a stunning aesthetic and secure aluminium casement window for your Wakefield home.

Energy Efficient

As window installers, we know that single glazed products are outdated and inefficient. Due to this, we use double glazing in all of our products. With double glazed aluminium casement windows, your overall U-values can be as low as 1.4W/m2K, which are government standard approved!

Keep the draughts and moisture out of your home when choosing our improved aluminium casement windows. With polyamide thermal breaks, we can help ‘break’ the amount of heat loss and provide you with the very best insulation on the market.

Sleek Sightlines

Aluminium casement windows include one of the best materials on the market for their thermal efficiency and low maintenance. Due to its incredible strength, manufacturers can use less material! With smaller, sleeker frames, all Wakefield homeowners can have the modern look of their dreams.

Choose one of our woodgrain finishes to maintain a traditional home. This way, you can receive the thermal efficiency and aesthetic allure you have always wanted. Improve the kerb appeal of your Wakefield property with the simple addition of aluminium casement windows!
