Owens Corning just committed to spend $3.9 billion to acquire Masonite International Corporation. But what did they get for their money? 

Here's a look at some of the details of this mega-deal.

The $3.9 billion cash deal will combine a 99-year-old door maker with a construction-materials company with roots back to the 1800s.

In the FDMC 300 list of top North American wood product manufacturers, the company ranks #8.

Since the announcement, shares of Masonite International Corp. rocketed toward their best day in 15 years Friday, after the doors maker agreed to be acquired.

NASDAQ.com, in its analysis of the deal, said:" Masonite's doors business, known for its innovation and quality, aligns seamlessly with OC's existing product portfolio. With Masonite's market-leading position and OC's commercial prowess, the synergy is expected to drive growth in the doors market. Leveraging OC's go-to-market model, the combined entity aims to capitalize on opportunities in residential construction."
