Triple Glazed Windows
Designed to meet the ever-increasing drive for enhanced thermal performance, the new Howarth Triple Glazed range uses the very best materials and techniques to ensure that every product meets the U-Values that increasing sections of the market are demanding.
These low U Values are achieved by using a 44mm Triple Glazed unit that increases its thermal capabilities, meaning it can be supplied with up to an A Rating from the BFRC for thermal performance. 
In addition, the Howarth Triple Glazed range also earns an A+ Rating from the BRE Green Guide for environmental performance.
Based on our popular flush-fit styling, the Triple Glazed window will fit into any traditional or contemporary development. A reversible hinge system means that the window also lends itself to use in multi-storey developments, where its reversible action makes tasks such as cleaning and simple maintenance much easier, reducing the need for external scaffolding. All main frame components and sashes are manufactured using clear-faced laminated Redwood for enhanced strength and durability, as well as providing a clear knot-free finish.
It should be noted though that all plant-on sections, sill and head drips are made from non-laminated Redwood which may contain knots.The new Howarth Triple Glazed window is also very good for the environment. Improved thermal performance means that less energy is needed to heat buildings, thus reducing the environmental impact. Frames can also be manufactured from FSC accredited timber with full chain of custody for sustainability.
