Standard white (HIPCA semi-gloss). Any standard powder paint, wood grain or anodised finish to order.- Warmer A Series 40 window will reduce heat loss by up to 50% using standard glass and up to 65% with a thermally efficient glass (low-E). Further improvements are possible using sealed glass units that create triple glazing. Perimeter mastic seals will almost eliminate drafts and ensure much greater comfort near the window. The effectiveness of the insulation is measured by U-values, the lower the figure the better the insulation.
