Ply Gem Results

Key Highlights Second Quarter Results

Second Quarter 2015 Highlights

• Sales increase of 22.8% was due to the Simonton and Canyon Stone acquisitions and growth within the U.S. businesses in each segment. The growth in the U.S. was partially offset by weaker market conditions in Canada and unfavorable foreign currency exchange rates which impacted sales by $7.5.

• Gross margin expansion of 340 basis points driven by increased average selling prices in both of our business segments, favorable freight costs, operating efficiency improvements in our Windows and Doors segment, and favorable commodity costs, partially offset by unfavorable foreign currency impact from a weakening Canadian dollar.

• Fifth consecutive year-over-year quarterly adjusted EBITDA improvement. Excluding acquisitions, incremental year-over-year quarterly adjusted EBITDA growth of 20.5%.

End Market Exposure (*)

• 45.5% increase in sales due largely to the Simonton acquisition which accounted for $86.5 of the sales growth. Excluding Simonton, sales for the U.S. business increased 5.8% due to higher average selling prices, improved product mix, and improvement in U.S. market conditions. Growth in the U.S. was partially offset by weaker market conditions in Western Canada and unfavorable foreign currency exchange rates which negatively impacted sales by $3.0.

• Gross margin improved by 660 basis points driven by $24.1 of Simonton gross margin and a 300 basis point gross margin improvement in our legacy windows businesses due to improved pricing, product mix and manufacturing efficiencies partially offset by unfavorable foreign currency.

• SG&A expense includes $17.9 of expense attributable to Simonton. Excluding Simonton, SG&A expense as a percent of net sales decreased from 13.4% to 13.2%.

Selling Price Increases

Q1 2015 announced price increases are effective for both business segments. W&D Segment selling price increases range from 6% to 15%. SFS Segment selling price increases range from 6% to 8%

Continued Implementation of Enterprise Lean and Sales & Operations Planning (S&OP) System in U.S. Windows and Doors

Enterprise Lean provides product simplification and improves manufacturing flexibility. Realized approximately $4.5 of benefit in 2014 and will provide for an estimated annual savings of approximately $10.0 when fully implemented in 2016

S&OP system provides enhanced capacity and resource planning system which will reduce future ramp-up costs and maximize fixed manufacturing investments

3Q 2015 Guidance

Based on the forecasted growth of the U.S. housing market and R&R spend, the impact of our enacted selling price increases and other margin enhancing initiatives, the expected impact of Simonton, anticipated acquisition synergies, and commodity fluctuations, we expect our adjusted EBITDA for 3Q 2015, in the range of $71.0 to $76.0 with the expectation that this year-over-year improvement trend will continue into the fourth quarter on a proportional basis

Economic Outlook & Guidance Expect Continued Steady Growth in U.S. Housing Starts

Expect continued overall moderate growth of 8% to 12% in U.S. housing

recovery in 2015, however we expect the market to experience periods of choppiness in the growth rate

Expect continued moderate growth of 3% to 4% in big ticket R&R spend

Overall Canadian housing starts expected to moderate relative to 2014 with lower starts in oil-producing regions of Western Canada partially offset by higher starts in other regions
