Tradesmith Ltd are proud to add to our extensive product range, the WarmCore aluminium bi-folding door system

Hi-tech elegance

Built around the belief that beauty doesn't have to compromise performance, WarmCore aluminium windows and doors were created out of the desire to combine the desirability and durability of aluminium with unparalleled insulation.

Precision-manufactured with a high quality surface finish and affording slim sight lines when installed, aluminium has become the material of choice for premium folding sliding door applications. WarmCore utilises a composite of materials to ensure an end product that is energy efficient and recyclable, combined with the premium quality, structural integrity and architectural design elegance of aluminium to create a product perfect for both residential and commercial building applications.

The unique, full width thermal core is key to why WarmCore products are 25% more thermally efficient than traditional aluminium systems.

High Strength Construction

From the design of the unique thermal core and the outer faces of the profile which are high grade aluminium, positioned to add the greatest structural rigidity, to the 60-80 micron thick (exceeding marine grade) powder coat finish, WarmCore has been designed to stand the test of time.

All fixings used are chosen to resist corrosion - and multi-point locks and purpose designed hinges have been precision engineered to perform consistently every single time, year on year.

In keeping with this attention to quality, WarmCore carries a 10 Year Guarantee - covering materials and surface finish. So you can feel confident in your decision to add WarmCore to your product range.

Thermal Core

At the heart of WarmCore products is a thermal core which significantly out-performs the polyamide thermal breaks commonly used in other aluminium systems. The fully concealed, bright orange, multi-chambered core maximises the use of lower conductivity material to improve thermal performance by up to 25%.

Dual Colour

WarmCore windows and doors come in four distinctive, modern colours and offer unrivalled thermal performance compared with traditional aluminium systems. 

WarmCore External Styling

With clean modern lines WarmCore creates windows with a refined and understated beauty. Perfectly suited to modern architecture as well as replacement projects, from large fixed pane 'picture windows' to windows with multiple openers, WarmCore has it covered.

Four external aluminium designs deliver a range of classic aesthetic styles:

1. Pencil round - 2. Chamfered - 3. Square - 4. Decorative


The WarmCore Advantage U-Value Performance

Using standard 28mm double glazing the WarmCore folding sliding door achieves a U-value of 1.5 W/m2 K. Upgrading to low-E glass gives an improved U-value of 1.4 W/m2 K, while a U-value as low as 1.0 W/m2 K is achievable using 44mm triple glazing. The advantage against traditional aluminium doors is clear, with many struggling to meet current legislation.

WarmCore has been designed from the ground up to offer market leading thermal performance, protecting against future tightening of Building Regulations – Part L.
